Hi, I was trying to move a disk between glusters domain storage without success. # gluster --version glusterfs 6.10 Now have a VM with this message: The VM has snapshot(s) with disk(s) in illegal status. Please don't shutdown the VM before successfully retrying the snapshot delete oVirt verison is Version 4.3.10.4-1.el7 I cannot delete the snapshot. What should I do? hanks -- Jose Ferradeira http://www.logicworks.pt

Latest version of Ovirt - 4.4.3 Hi everyboby. I have tryed to install hosted engine from ovirt cockpit, but when select iSCSI target I give the same error - Error: Cannot retrieve iSCSI LUNs. After that I have installed hosted engine from console with command - "hosted-engine --deploy" and than installed successfully. From console was able to retrieve iSCSI luns and select one there. Who can try to deploy ovirt from cockpit?

Guest OS Memory Free/Cached/Buffered: Not Configured
by Stefan Seifried 30 Nov '20

30 Nov '20

Hi, I'm quite new to oVirt, so my apologizies if I'm asking something dead obvious: I noticed that there is an item in the 'General Tab' of each VM, which says 'Guest OS Memory Free/Cached/Buffered' and on all my VM's it says 'Not Configured'. Right now I'm trying to figure out how to enable this feature. I assume that this gives me the equivalent output of executing 'free' on the shell on a Linux guest. Googling and digging around the VMM guide did not give me any pointers so far. Thanks in advance, Stefan PS: A little background info: I have one 'client' which keeps nagging me to increase the RAM on his VM because it's constantly operating at 95% memory load (as shown on the VM dashboard). After a quick investigation with 'free' I could see that Linux has built up the disk cache to 12G (from 16G total, no swapping occured). My intention is to make the real memory load visible to him, as he has already access to the VM portal for shutdown/restart/etc.

Re: Constantly XFS in memory corruption inside VMs

Are you using "nobarrier" mount options in the VM ? If yes, can you try to remove the "nobarrrier" option.

If there's any corruption it may be silent corruption... I've cases where the VM was new, just installed, run dnf -y update to get the updated packages, rebooted, and boom XFS corruption. So perhaps the motion process isn't the one to blame. But, in fact, I remember when moving a VM that it went down during the process and when I rebooted it was corrupted. But this may not seems related. It perhaps was already in a inconsistent state. Anyway, here's the mount options: Host1: 192.168.10.14:/mnt/pool0/ovirt/vm on /rhev/data-center/mnt/192.168.10.14:_mnt_pool0_ovirt_vm type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,soft,nosharecache,proto=tcp,timeo=100,retrans=3,sec=sys,clientaddr=192.168.10.1,local_lock=none,addr=192.168.10.14) Host2: 192.168.10.14:/mnt/pool0/ovirt/vm on /rhev/data-center/mnt/192.168.10.14:_mnt_pool0_ovirt_vm type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,soft,nosharecache,proto=tcp,timeo=100,retrans=3,sec=sys,clientaddr=192.168.10.1,local_lock=none,addr=192.168.10.14) The options are the default ones.

Ovirt 4.4.3 - Unable to start hosted engine
by Marco Marino 28 Nov '20

28 Nov '20

Hi, I have an ovirt 4.4.3 with 2 clusters, hosted engine and iscsi storage. First cluster, composed of 2 servers (host1 and host2), is dedicated to the hosted engine, the second cluster is for vms. Furthermore, there is a SAN with 3 luns: one for hosted engine storage, one for vms and one unused. My SAN is built on top of a pacemaker/drbd cluster with 2 nodes with a virtual ip used as iscsi Portal IP. Starting from today, after a failover of the iscsi cluster, I'm unable to start the hosted engine. It seems that there is some problem with storage. Actually I have only one node (host1) running in the cluster. It seems there is some lock on lvs, but I'm not sure of this. Here are some details about the problem: 1. iscsiadm -m session iSCSI Transport Class version 2.0-870 version 6.2.0.878-2 Target: iqn.2003-01.org.linux-iscsi.s1-node1.x8664:sn.2a734f67d5b1 (non-flash) Current Portal: 10.3.8.8:3260,1 Persistent Portal: 10.3.8.8:3260,1 ********** Interface: ********** Iface Name: default Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:4b668221d9a9 Iface IPaddress: 10.3.8.10 Iface HWaddress: default Iface Netdev: default SID: 1 iSCSI Connection State: LOGGED IN iSCSI Session State: LOGGED_IN Internal iscsid Session State: NO CHANGE ********* Timeouts: ********* Recovery Timeout: 5 Target Reset Timeout: 30 LUN Reset Timeout: 30 Abort Timeout: 15 ***** CHAP: ***** username: <empty> password: ******** username_in: <empty> password_in: ******** ************************ Negotiated iSCSI params: ************************ HeaderDigest: None DataDigest: None MaxRecvDataSegmentLength: 262144 MaxXmitDataSegmentLength: 262144 FirstBurstLength: 65536 MaxBurstLength: 262144 ImmediateData: Yes InitialR2T: Yes MaxOutstandingR2T: 1 ************************ Attached SCSI devices: ************************ Host Number: 7 State: running scsi7 Channel 00 Id 0 Lun: 0 Attached scsi disk sdb State: running scsi7 Channel 00 Id 0 Lun: 1 Attached scsi disk sdc State: running 2. vdsm.log errors: 2020-11-27 18:37:16,786+0100 INFO (jsonrpc/0) [api] FINISH getStats error=Virtual machine does not exist: {'vmId': 'f3a1194d-0632-43c6-8e12-7f22518cff87'} (api:129) ..... 2020-11-27 18:37:52,864+0100 INFO (jsonrpc/4) [vdsm.api] FINISH getVolumeInfo error=(-223, 'Sanlock resource read failure', 'Lease does not exist on storage') from=::1,60880, task_id=138a3615-d537-4e5f-a39c-335269ad0917 (api:52) 2020-11-27 18:37:52,864+0100 ERROR (jsonrpc/4) [storage.TaskManager.Task] (Task='138a3615-d537-4e5f-a39c-335269ad0917') Unexpected error (task:880) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 887, in _run return fn(*args, **kargs) File "<decorator-gen-159>", line 2, in getVolumeInfo File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/storage/hsm.py", line 3142, in getVolumeInfo info = self._produce_volume(sdUUID, imgUUID, volUUID).getInfo() File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 258, in getInfo leasestatus = self.getLeaseStatus() File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 203, in getLeaseStatus self.volUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 549, in inquireVolumeLease return self._domainLock.inquire(lease) File "/usr/lib/python3.6/site-packages/vdsm/storage/clusterlock.py", line 464, in inquire sector=self._block_size) sanlock.SanlockException: (-223, 'Sanlock resource read failure', 'Lease does not exist on storage') 2020-11-27 18:37:52,865+0100 INFO (jsonrpc/4) [storage.TaskManager.Task] (Task='138a3615-d537-4e5f-a39c-335269ad0917') aborting: Task is aborted: "value=(-223, 'Sanlock resource read failure', 'Lease does not exist on storage') abortedcode=100" (task:1190) 3. supervdsm.log MainProcess|monitor/de4645f::DEBUG::2020-11-27 18:41:25,286::commands::153::common.commands::(start) /usr/bin/taskset --cpu-list 0-11 /usr/sbin/dmsetup remove de4645fc--f379--4837--916b--a0c2b89927d9-dfa4e933--2b9c--4057--a4c5--aa4485b070e9 (cwd None) MainProcess|monitor/de4645f::DEBUG::2020-11-27 18:41:25,293::commands::98::common.commands::(run) FAILED: <err> = b'device-mapper: remove ioctl on de4645fc--f379--4837--916b--a0c2b89927d9-dfa4e933--2b9c--4057--a4c5--aa4485b070e9 failed: Device or resource busy\nCommand failed.\n';

[ANN] oVirt 4.4.4 Third Release Candidate is now available for testing
by Sandro Bonazzola 27 Nov '20

27 Nov '20

oVirt 4.4.4 Third Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.4 Third Release Candidate for testing, as of November 26th, 2020. This update is the fourth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.4 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.4 (redeploy in case of already being on 4.4.4). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer * oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

"gluster-ansible-roles is not installed on Host" error on Cockpit
by Hesham Ahmed 26 Nov '20

26 Nov '20

On a new 4.3.1 oVirt Node installation, when trying to deploy HCI (also when trying adding a new gluster volume to existing clusters) using Cockpit, an error is displayed "gluster-ansible-roles is not installed on Host. To continue deployment, please install gluster-ansible-roles on Host and try again". There is no package named gluster-ansible-roles in the repositories: [root@localhost ~]# yum install gluster-ansible-roles Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist, package_upload, product-id, search-disabled-repos, subscription-manager, vdsmupgrade This system is not registered with an entitlement server. You can use subscription-manager to register. Loading mirror speeds from cached hostfile * ovirt-4.3-epel: mirror.horizon.vn No package gluster-ansible-roles available. Error: Nothing to do Uploading Enabled Repositories Report Cannot upload enabled repos report, is this client registered? This is due to check introduced here: https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js Changing the line from: [ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" } to [ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" } resolves the issue. The above code snippet is installed at /usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g' /usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart cockpit"
