[Users] Nodes lose storage at random
Hi All, We're seeing some weird issues in our ovirt setup. We have 4 nodes connected and an NFS (v3) filestore (FreeBSD/ZFS). Once in a while, it seems at random, a node loses their connection to storage, recovers it a minute later. The other nodes usually don't lose their storage at that moment. Just one, or two at a time. We've setup extra tooling to verify the storage performance at those moments and the availability for other systems. It's always online, just the nodes don't think so. The engine tells me this: 2014-02-18 11:48:03,598 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain d88764c8-ecc3-4f22-967e-2ce225ac4498:Export in problem. vds: hv5 2014-02-18 11:48:18,909 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain e9f70496-f181-4c9b-9ecb-d7f780772b04:Data in problem. vds: hv5 2014-02-18 11:48:45,021 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-18) [46683672] Failed to refresh VDS , vds = 66e6aace-e51d-4006-bb2f-d85c2f1fd8d2 : hv5, VDS Network Error, continuing. 2014-02-18 11:48:45,070 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-41) [2ef1a894] Correlation ID: 2ef1a894, Call Stack: null, Custom Event ID: -1, Message: Invalid status on Data Center GS.

Meital, I'm running the latest stable oVirt, 3.3.3 on Centos 6.5. For my nodes I use the node iso CentOS 6 "oVirt Node - 3.0.1 - 1.0.2.el6". I have no ways of reproducing just yet. I can confirm that it's happening on all nodes in the cluster. And every time a node goes offline, this error pops up. Could the fact that lockd & statd were not running on the NFS host cause this error? Is there a workaround available that we know of?

Meital,
I'm running the latest stable oVirt, 3.3.3 on Centos 6.5. For my nodes I use the node iso CentOS 6 "oVirt Node - 3.0.1 - 1.0.2.el6".
I have no ways of reproducing just yet. I can confirm that it's happening on all nodes in the cluster. And every time a node goes offline, this error pops up.
Could the fact that lockd & statd were not running on the NFS host cause this error? Is there a workaround available that we know of?

Which oVirt version are you using? I see that there are a few old bugs that describes the same behaviour, but with different reproduction steps, for example [1], [2].
Can you think of any reproduction steps that might be causing this issue?

Hi All,
We're seeing some weird issues in our ovirt setup. We have 4 nodes connected and an NFS (v3) filestore (FreeBSD/ZFS).
Once in a while, it seems at random, a node loses their connection to storage, recovers it a minute later. The other nodes usually don't lose their storage at that moment. Just one, or two at a time.
We've setup extra tooling to verify the storage performance at those moments and the availability for other systems. It's always online, just the nodes don't think so.
The engine tells me this:
2014-02-18 11:48:03,598 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain d88764c8-ecc3-4f22-967e-2ce225ac4498:Export in problem. vds: hv5 2014-02-18 11:48:18,909 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain e9f70496-f181-4c9b-9ecb-d7f780772b04:Data in problem. vds: hv5 2014-02-18 11:48:45,021 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-18) [46683672] Failed to refresh VDS , vds = 66e6aace-e51d-4006-bb2f-d85c2f1fd8d2 : hv5, VDS Network Error, continuing. 2014-02-18 11:48:45,070 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-41) [2ef1a894] Correlation ID: 2ef1a894, Call Stack: null, Custom Event ID: -1, Message: Invalid status on Data Center GS. Setting Data Center status to Non Responsive (On host hv5, Error: Network error during communication with the Host.).
The export and data domain live over NFS. There's another domain, ISO, that lives on the engine machine, also shared over NFS. That domain doesn't have any issue at all.
Attached are the logfiles for the relevant time period for both the engine server and the node. The node by the way, is a deployment of the node ISO, not a full blown installation.
Any clues on where to begin searching? The NFS server shows no issues nor anything in the logs. I did notice that the statd and lockd daemons were not running, but I wonder if that can have anything to do with the issue.

To follow up on this: The setup has only ~80 VM's active right now. The 2 bugreports are not in scope for this setup, the issues occur at random, even when there's no activity (create/delete VM's) and there are only 4 directories in /rhev/data-center/mnt/.

Meital,

I have no ways of reproducing just yet. I can confirm that it's happening on all nodes in the cluster. And every time a node goes offline, this error pops up.
Could the fact that lockd & statd were not running on the NFS host cause this error? Is there a workaround available that we know of?

Hi All,
We're seeing some weird issues in our ovirt setup. We have 4 nodes connected and an NFS (v3) filestore (FreeBSD/ZFS).
Once in a while, it seems at random, a node loses their connection to storage, recovers it a minute later. The other nodes usually don't lose their storage at that moment. Just one, or two at a time.
We've setup extra tooling to verify the storage performance at those moments and the availability for other systems. It's always online, just the nodes don't think so.
The engine tells me this:
2014-02-18 11:48:03,598 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain d88764c8-ecc3-4f22-967e-2ce225ac4498:Export in problem. vds: hv5 2014-02-18 11:48:18,909 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain e9f70496-f181-4c9b-9ecb-d7f780772b04:Data in problem. vds: hv5 2014-02-18 11:48:45,021 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-18) [46683672] Failed to refresh VDS , vds = 66e6aace-e51d-4006-bb2f-d85c2f1fd8d2 : hv5, VDS Network Error, continuing. 2014-02-18 11:48:45,070 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-41) [2ef1a894] Correlation ID: 2ef1a894, Call Stack: null, Custom Event ID: -1, Message: Invalid status on Data Center GS. Setting Data Center status to Non Responsive (On host hv5, Error: Network error during communication with the Host.).
The export and data domain live over NFS. There's another domain, ISO, that lives on the engine machine, also shared over NFS. That domain doesn't have any issue at all.
Attached are the logfiles for the relevant time period for both the engine server and the node. The node by the way, is a deployment of the node ISO, not a full blown installation.
Any clues on where to begin searching? The NFS server shows no issues nor anything in the logs. I did notice that the statd and lockd daemons were not running, but I wonder if that can have anything to do with the issue.

One other interesting fact is that each node has 4 NFS mountpoints. 2 (data & export) to the main SAN, 1 to the engine machine for ISO and one to the legacy SAN. When this issue occurs, the only mountpoint in a problem state seem to be the 2 mountpoints to the main SAN: 2014-02-18 11:48:03,598 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain d88764c8-ecc3-4f22-967e-2ce225ac4498:Export in problem. vds: hv5 2014-02-18 11:48:18,909 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-6-thread-48) domain e9f70496-f181-4c9b-9ecb-d7f780772b04:Data in problem. vds: hv5 On Tue, Feb 18, 2014 at 3:04 PM, Johan Kooijman <mail@johankooijman.com>wrote:

Meaning that vdsm was restarted.
Which oVirt version are you using? I see that there are a few old bugs that describes the same behaviour, but with different reproduction steps, for example [1], [2].
Can you think of any reproduction steps that might be causing this issue?

Hi All,
We're seeing some weird issues in our ovirt setup. We have 4 nodes connected and an NFS (v3) filestore (FreeBSD/ZFS).
Once in a while, it seems at random, a node loses their connection to storage, recovers it a minute later. The other nodes usually don't lose their storage at that moment. Just one, or two at a time.
We've setup extra tooling to verify the storage performance at those moments and the availability for other systems. It's always online, just the nodes don't think so.
The engine tells me this:

Setting Data Center status to Non Responsive (On host hv5, Error: Network error during communication with the Host.).
The export and data domain live over NFS. There's another domain, ISO, that lives on the engine machine, also shared over NFS. That domain doesn't have any issue at all.
Attached are the logfiles for the relevant time period for both the engine server and the node. The node by the way, is a deployment of the node ISO, not a full blown installation.
Any clues on where to begin searching? The NFS server shows no issues nor anything in the logs. I did notice that the statd and lockd daemons were not running, but I wonder if that can have anything to do with the issue.

Meital, It's been 4 days since the last crash - but 5 minutes ago one of the nodes had the same issues. I've been running the script on the SPM as you mentioned. It turns out that at the time the node went down, the SPM didn't have more remoteFileHandler processes than before or after the crash - 29. I'm not sure what to make of this piece of information.

Hi Johan,
Can you please run something like this on the spm node? while true; do echo `date; ps ax | grep -i remotefilehandler | wc -l` >> /tmp/handler_num.txt; sleep 1; done
When it'll happen again, please stop the script, and write here the maximum number and the time that it happened.
Also, please check if "process_pool_max_slots_per_domain" is defined in /etc/vdsm/vdsm.conf, and if so, what's the value? (if it's not defined there, the default is 10)
Thanks!

To follow up on this: The setup has only ~80 VM's active right now. The 2 bugreports are not in scope for this setup, the issues occur at random, even when there's no activity (create/delete VM's) and there are only 4 directories in /rhev/data-center/mnt/.

Meital,
I'm running the latest stable oVirt, 3.3.3 on Centos 6.5. For my nodes I use the node iso CentOS 6 "oVirt Node - 3.0.1 - 1.0.2.el6".
I have no ways of reproducing just yet. I can confirm that it's happening on all nodes in the cluster. And every time a node goes offline, this error pops up.
Could the fact that lockd & statd were not running on the NFS host cause this error? Is there a workaround available that we know of?

We can see in /var/log/messages, that sanlock failed to write to the ids lockspace [1], which after 80 seconds [2], caused vdsm to loose its host id lease. In this case, sanlock kill vdsm [3], which die after 11 retries [4]. Then vdsm is respawned again [5]. This is expected. We don't know why sanlock failed to write to the storage, but in [6] the kernel tell us that the nfs server is not responding. Since the nfs server is accessible from other machines, it means you have some issue with this host. Later the machine reboots [7], and nfs server is still not accessible. Then you have lot of WARN_ON call traces [8], that looks related to network code. We can see that you are not running most recent kernel [7]. We experienced various nfs issues during the 6.5 beta.

Thanks for looking into it. I've been running the ovirt ISO untill now, will switch to stock C6.5 to see if it makes a difference. On Sat, Feb 22, 2014 at 8:57 PM, Nir Soffer <nsoffer@redhat.com> wrote:

We can see in /var/log/messages, that sanlock failed to write to the ids lockspace [1], which after 80 seconds [2], caused vdsm to loose its host id lease. In this case, sanlock kill vdsm [3], which die after 11 retries [4]. Then vdsm is respawned again [5]. This is expected.
We don't know why sanlock failed to write to the storage, but in [6] the kernel tell us that the nfs server is not responding. Since the nfs server is accessible from other machines, it means you have some issue with this host.
Later the machine reboots [7], and nfs server is still not accessible. Then you have lot of WARN_ON call traces [8], that looks related to network code.
We can see that you are not running most recent kernel [7]. We experienced various nfs issues during the 6.5 beta.
I would try to get help from kernel folks about this.

Been reinstalling to stocj CentOS 6.5 last night, all successful. Until roughly midnight GMT, 2 out of 4 hosts were showing the same errors.
Any more suggestions?
Lets see the logs from these hosts?
Interestingly enough - same thing happened today, around the same time. Logs from this host are attached. Around 1:10 AM stuff starts to go wrong again. Same pattern - we reboot the node and the node is fine again. On Sun, Feb 23, 2014 at 12:11 PM, Nir Soffer <nsoffer@redhat.com> wrote:

So we made some progress, we know that it is not a problem with old kernel. In messages we see the same picture: 1. sanlock fail to renew the lease 2. after 80 secodns, kill vdsm 3. sanlock and vdsm cannot access the storage 4. kernel complain about nfs server timeouts (explains why sanlock failed to renew the lease) 5. after reboot, nfs is accessible again 6. after few days goto step 1 This looks like kernel nfs issue. Could be also kvm issue (running bsd on the one of the vm?) Could be also some incompatibility with the nfs server - maybe you are using esoteric configuration options? CCing Ronen, in case this is related to kvm. thread: http://lists.ovirt.org/pipermail/users/2014-February/021507.html Nir

Not seems to be related to KVM. Adding Ric Wheeler. Ronen.

Gents, I'm sending this email for archiving purposes: It's been a while since my last update on this topic. It turned out that although only one node, randomly, at a time lost connection to storage, the issue was not at all with ovirt, but with the storage. I'd like to refer to these 2 topics for more information: http://lists.freebsd.org/pipermail/freebsd-net/2014-March/038061.html and http://lists.freebsd.org/pipermail/freebsd-net/2014-February/037967.html. Keywords: ovirt freebsd 9.2 zfs ixgbe intel 10gbit NFS On Mon, Feb 24, 2014 at 3:55 PM, Ronen Hod <rhod@redhat.com> wrote:
