Changing Network Interfaces on host causes bond to go offline
by oBSD Nub 29 Jul '18

29 Jul '18

Everytime I try to change assigned Logical networks (add ip addresses, assign a logical network, etc) the bond0 interface winds up going down. I have to do a ifup bond0 from the console, and the engine reconnects. After a lot of digging, I think this is the offending command, but I don't know how to read it or next troubleshooting steps. Anyone want to point me in the right direction? Thanks! 2018-07-28 18:07:36,661-0500 WARN (vdsm.Scheduler) [Executor] Worker blocked: <Worker name=jsonrpc/6 running <Task <JsonRpcTask {'params': {u'connectionParams': [{u'netIfaceName': u'bond0.3001', u'id': u'0808bc71-b5f7-4886-9dc8-e21b0d2abf14', u'connection': u'192.168.200.81', u'iqn': u'iqn.2002-10.com.infortrend:raid.uid577981.001', u'user': u'', u'tpgt': u'1', u'ifaceName': u'bond0.3001', u'password': '********', u'port': u'3260'}, {u'netIfaceName': u'bond0.3002', u'id': u'77c7e9dd-cd46-48be-ade1-06645772c405', u'connection': u'192.168.200.81', u'iqn': u'iqn.2002-10.com.infortrend:raid.uid577981.001', u'user': u'', u'tpgt': u'1', u'ifaceName': u'bond0.3002', u'password': '********', u'port': u'3260'}], u'storagepoolID': u'2cde92be-7b43-11e8-b08d-00505690367f', u'domainType': 3}, 'jsonrpc': '2.0', 'method': u'StoragePool.connectStorageServer', 'id': u'9a414389-2b42-4a20-b59c-c3bc9d19c7b4'} at 0x7f29980cdcd0> timeout=60, duration=60 at 0x7f29980cdfd0> task#=4 at 0x7f299837af10>, traceback: File: "/usr/lib64/python2.7/threading.py", line 785, in __bootstrap self.__bootstrap_inner() File: "/usr/lib64/python2.7/threading.py", line 812, in __bootstrap_inner self.run() File: "/usr/lib64/python2.7/threading.py", line 765, in run self.__target(*self.__args, **self.__kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/common/concurrent.py", line 194, in run ret = func(*args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 301, in _run self._execute_task() File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 315, in _execute_task task() File: "/usr/lib/python2.7/site-packages/vdsm/executor.py", line 391, in __call__ self._callable() File: "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 523, in __call__ self._handler(self._ctx, self._req) File: "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 566, in _serveRequest response = self._handle_request(req, ctx) File: "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 606, in _handle_request res = method(**params) File: "/usr/lib/python2.7/site-packages/vdsm/rpc/Bridge.py", line 197, in _dynamicMethod result = fn(*methodArgs) File: "/usr/lib/python2.7/site-packages/vdsm/API.py", line 1070, in connectStorageServer connectionParams) File: "/usr/lib/python2.7/site-packages/vdsm/storage/dispatcher.py", line 73, in wrapper result = ctask.prepare(func, *args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 108, in wrapper return m(self, *a, **kw) File: "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 1179, in prepare result = self._run(func, *args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File: "<string>", line 2, in connectStorageServer File: "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 48, in method ret = func(*args, **kwargs) File: "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 2395, in connectStorageServer conObj.connect() File: "/usr/lib/python2.7/site-packages/vdsm/storage/storageServer.py", line 487, in connect iscsi.addIscsiNode(self._iface, self._target, self._cred) File: "/usr/lib/python2.7/site-packages/vdsm/storage/iscsi.py", line 217, in addIscsiNode iscsiadm.node_login(iface.name, target.address, target.iqn) File: "/usr/lib/python2.7/site-packages/vdsm/storage/iscsiadm.py", line 327, in node_login portal, "-l"]) File: "/usr/lib/python2.7/site-packages/vdsm/storage/iscsiadm.py", line 122, in _runCmd return misc.execCmd(cmd, printable=printCmd, sudo=True, sync=sync) File: "/usr/lib/python2.7/site-packages/vdsm/common/commands.py", line 80, in execCmd (out, err) = p.communicate(data) File: "/usr/lib64/python2.7/site-packages/subprocess32.py", line 924, in communicate stdout, stderr = self._communicate(input, endtime, timeout) File: "/usr/lib64/python2.7/site-packages/subprocess32.py", line 1706, in _communicate orig_timeout) File: "/usr/lib64/python2.7/site-packages/subprocess32.py", line 1779, in _communicate_with_poll ready = poller.poll(self._remaining_time(endtime)) (executor:363)

NFS Storage Advice?
by Wesley Stewart 28 Jul '18

28 Jul '18

I currently have a NFS server with decent speeds. I get about 200MB/s write and 400+ MB/s read. My single node oVirt host has a mirrored SSD store for my Windows 10 VM, and I have about 3-5 VMs running on the NFS data store. However, VM/s on the NFS datastore are SLOW. They can write to their own disk around 10-50 MB/s. However a VM on the mirrored SSD drives can get 150-250 MB/s transfer speed from the same NFS storage (Through NFS mounts). Does anyone have any suggestions on what I could try to speed up the NFS storage for the VMs? My single node ovirt box has a 1ft Cat6 crossover cable plugged directly into my NFS servers 10GB port. Thanks!

Spice console pixelated noise on display changes
by Mitja Mihelič 28 Jul '18

28 Jul '18

Dear all, We are running the following setup: ovirt-engine host: - CentOS release 7.5.1804 - ovirt-engine-4.1.9.1-1.el7.centos.noarch - spice-html5-0.1.7-1.el7.noarch We have noticed problems with the Spice console. When it opens and displays the information presented by the VM's console it is OK at first. But as soon as any part of the display changes, that part gets replaced by random pixelated noise. For example I open the console of a standard CentOS server. When I type something at the login prompt the text is invisible and random pixels are displayed at the position of the blinking cursor. Please see attached screenshot spice-1-login_typing_and_cursor_waiting.png. Please also see other the attached screenshots. Login prompt after VM reboot: spice-2-login_after_boot.png Login prompt after hitting Enter a few times: spice-3-login_2x_enter.png We have tried and succesfully reproduced the issue on OSX (Chrome, FF, Safari) and Windows (Chrome, FF). VNC works fine. Why would this be happening? Help would be very much appreciated. Kind regards, Mitja -- Mitja Mihelič ARNES, Tehnološki park 18, p.p. 7, SI-1001 Ljubljana, Slovenia tel: +386 1 479 8877, fax: +386 1 479 88 7

Understanding JBOD brick configuration
by Jayme 27 Jul '18

27 Jul '18

I'm deploying three host Ovirt HCI and I'm a bit confused about how to configure the glusterFS volumes and bricks in the cockpit. My three hosts are configured the exact same way physically: 2x250GB SSDs in Raid 1 for OS 2 x 2TB SSD in JBOD which I intend to use for Gluster (devices sda and sdb) So on Step 3 (Volumes) of gluster deployment I'm leaving the volumes default (with no arbiter as I want replica 3). So that is creating a volume for Engine, Data and VMstore On step 4 (Bricks) I'm choosing jbod and next is where I'm getting confused. I have to specify the device name and size for each volume. It appears that I have to break up sda and sdb devices here. I have 4 TB total between the two JBOD drives but does that mean I can only specify up to 2TB usable for the data volume (on either sda or sdb) then split the space on the second 2TB drive between engine and vmstore? If so this seems like an awful waste of a 2TB drive for use for only engine and vmstore volumes. With my JBOD configuration of two separate disks per hosts is there any way I can have a data volume use most of that space say 3.5TB and the rest goes to engine/vmstore? It was my understanding that glusterFS would pool all available space together and I could use it however I wanted. Can I achieve this without putting the 2TB disks in to a raid configuraiton? Thanks!

trunked ports
by william.dossett＠gmail.com 27 Jul '18

27 Jul '18

Hi, I setup oVirt a few years back. now that the HCI is real, I am revisiting it. I have deployed with Gluster, and am now moving on to networking. I come from a VMware shop and normally we trunk all the network ports exposing all VLANs to the hosts and place VMs in Portgoups that are tagged with VLANs. I did manage to do this years back but I am struggling to get this to work today. I had pretty limited hardware back then and I thought I installed using vlan tagging and trunked ports, but I don't see any option to do this using the glusterfs and hosted engine setup. Each host has a dual port 10Gb NICs I use one for storage that is connected to my storage network and one for ovirtmgmt. (I need to add another of these for redundancy down the road, but no money for that at the moment) The hosts also have 4 x 1Gb ports. So in lieu of being able to configure vlan tagging to trunked ports on hosted engine deploy, I am considering cabling up a 1 Gb port on each in my management services VLAN and when it is all up and running create another logical network (or several of them as I think these equate to what is a vlan tagged port group in VMware) with the 10Gb NIC backing for VMs. Does that sound reasonable? Or if anyone can point me to any docs that describe how to deploy to a specific VLAN with trunk ports, that would be nice as well as I won't have to actually go to the office and run additional cables. Appreciate any advice Bill
