oVirt gluster sanlock issue
by Abi Askushi 08 Jun '17

08 Jun '17

Hi All, I have installed successfully several times oVirt (version 4.1) with 3 nodes on top glusterfs. This time, when trying to configure the same setup, I am facing the following issue which doesn't seem to go away. During installation i get the error: Failed to execute stage 'Misc configuration': Cannot acquire host id: (u'a5a6b0e7-fc3f-4838-8e26-c8b4d5e5e922', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argument')) The only different in this setup is that instead of standard partitioning i have GPT partitioning and the disks have 4K block size instead of 512. The /var/log/sanlock.log has the following lines: 2017-06-03 19:21:15+0200 23450 [943]: s9 lockspace ba6bd862-c2b8-46e7-b2c8-91e4a5bb2047:250:/rhev/data-center/mnt/_var_lib_ovirt-hosted-engin-setup_tmptjkIDI/ba6bd862-c2b8-46e7-b2c8-91e4a5bb2047/dom_md/ids:0 2017-06-03 19:21:36+0200 23471 [944]: s9:r5 resource ba6bd862-c2b8-46e7-b2c8-91e4a5bb2047:SDM:/rhev/data-center/mnt/_var_lib_ovirt-hosted-engine-setup_tmptjkIDI/ba6bd862-c2b8-46e7-b2c8-91e4a5bb2047/dom_md/leases:1048576 for 2,9,23040 2017-06-03 19:21:36+0200 23471 [943]: s10 lockspace a5a6b0e7-fc3f-4838-8e26-c8b4d5e5e922:250:/rhev/data-center/mnt/glusterSD/10.100.100.1: _engine/a5a6b0e7-fc3f-4838-8e26-c8b4d5e5e922/dom_md/ids:0 2017-06-03 19:21:36+0200 23471 [23522]: a5a6b0e7 aio collect RD 0x7f59b00008c0:0x7f59b00008d0:0x7f59b0101000 result -22:0 match res 2017-06-03 19:21:36+0200 23471 [23522]: read_sectors delta_leader offset 127488 rv -22 /rhev/data-center/mnt/glusterSD/10.100.100.1: _engine/a5a6b0e7-fc3f-4838-8e26-c8b4d5e5e922/dom_md/ids 2017-06-03 19:21:37+0200 23472 [930]: s9 host 250 1 23450 88c2244c-a782-40ed-9560-6cfa4d46f853.v0.neptune 2017-06-03 19:21:37+0200 23472 [943]: s10 add_lockspace fail result -22 And /var/log/vdsm/vdsm.log says: 2017-06-03 19:19:38,176+0200 WARN (jsonrpc/3) [storage.StorageServer.MountConnection] Using user specified backup-volfile-servers option (storageServer:253) 2017-06-03 19:21:12,379+0200 WARN (periodic/1) [throttled] MOM not available.

Power failure recovery
by Chris Boot 07 Jun '17

07 Jun '17

Hi all, We've got a three-node "hyper-converged" oVirt 4.1.2 + GlusterFS cluster on brand new hardware. It's not quite in production yet but, as these things always go, we already have some important VMs on it. Last night the servers (which aren't yet on UPS) suffered a brief power failure. They all booted up cleanly and the hosted engine started up ~10 minutes afterwards (presumably once the engine GlusterFS volume was sufficiently healed and the HA stack realised). So far so good. As soon at the HostedEngine started up it tried to start all our Highly Available VMs. Unfortunately our master storage domain was as yet inactive as GlusterFS was presumably still trying to get it healed. About 10 minutes later the master domain was activated and "reconstructed" and an SPM was selected, but oVirt had tried and failed to start all the HA VMs already and didn't bother trying again. All the VMs started just fine this morning when we realised what happened and logged-in to oVirt to start them. Is this known and/or expected behaviour? Can we do anything to delay starting HA VMs until the storage domains are there? Can we get oVirt to keep trying to start HA VMs when they fail to start? Is there a bug for this already or should I be raising one? Thanks, Chris -- Chris Boot bootc(a)bootc.net

Hosted engine question: why power-off

Why would the hosted engine power itself off? I did not issue a power off command Broadcast message from root@ovirt-engine (Wed 2017-06-07 13:45:10 UTC): "VM is shutting down!" The system is going down for power-off at Wed 2017-06-07 13:46:10 UTC!

nic order
by Nathanaël Blanchet 07 Jun '17

07 Jun '17

Hi all, I added a new nic on all my vms, but the MAC address pool was too small. So I extended it from 00:1a:4a:22:1f:00 to 00:1a:4a:22:1f:ff => 00:1a:4a:22:1e:00 to 00:1a:4a:22:1f:ff. It was okay but when rebooting some vms, nics are interverted and I couldn't join my vm on ip! I noticed nics were ordered now from the smallest MAC address to the greatest one, so the last plugged nic from the new pool was now the first in the vm, and all nics were moved at the bottom. Is it an expected behaviour? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

hosted engine install fails for bonded interface
by Ramachandra Reddy Ankireddypalle 07 Jun '17

07 Jun '17

Hi, I created a bonded interface consisting of two network interfaces. When I tried to install hosted engine over the bonded interface, it fails at the end with the following error message: [ ERROR ] Cannot automatically add the host to cluster Default: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> </p> </body></html> If I try to install over the eth interface instead of the bonded interface the install succeeds. Please suggest what needs to be done to use bonded interface. Thanks and Regards, Ram
