python sdk v3 host nic issues

VM storage issue after snapshot deletion
by Ollie Armstrong 05 Aug '16

05 Aug '16

Hi everyone. I'm having an issue with a VM after initiating a snapshot deletion. Shortly after the deletion started the VM was paused and has not recovered since, this was over 12 hours ago. I've dug into the logs and here's some things that jumped out at me: engine.log Message: VM XXXXXX has been paused due to unknown storage error. vdsm.log Improbable extension request for volume cb180795-1da8-4a4c-90a9-b42d00485018 on domain 0243ebd9-fd3f-4674-b4e7-05af734280e7, pausing the VM to avoid corruptions (capacity: 53687091200, allocated: 5750586880, physical: 1073741824, next physical size: 2147483648) The vdsm.log line I've quoted is repeated approximately every 2 seconds from the first occurrence and is still going. I've attached engine.log and uploaded vdsm.log to my server [1] as it was 10M. The VM in question has the ID 184f89f4-8427-4a28-8787-8912f5c5f038. The VM is still paused and cannot be resumed, seemingly as a precaution to avoid corruption. Is there anything I can do to recover the data on the disk? All help is greatly appreciated. I'm running oVirt 3.6.6.2-1 on CentOS 7. Cheers, Ollie [1] https://ollie.io/vdsm.log

No VMs to import
by Frank Rothenstein 05 Aug '16

05 Aug '16

Hello, now that gluster 3.7.14 is out I was able to change the storage domains mount from NFS back to GlusterFS. The first domain worked flawlessly this way: set domain to maintenance -> detach -> remove -> import Domain (this time GlusterFS) -> import VMs The other storage domain works too, but in the gui is no tab Import VMs or Import Disks. Is there any other way to rescan/reimport VMs on this storage domain?

Hi, I try to install the hosted_engine on 3 Servers which host also the gluster data storage. When I install now the hosted_engine, which storage path should I use? Setup 1: server1: server1.san:/hosted_engine server2: server1.san:/hosted_engine server3: server1.san:/hosted_engine Setup 2: server1: localhost:/hosted_engine server2: localhost:/hosted_engine server3: localhost:/hosted_engine Setup 3: /etc/hosts: 127.0.0.1 gluster server1: gluster:/hosted_engine server2: gluster:/hosted_engine server3: gluster:/hosted_engine Other Setup?

Multipath iSCSI with several IPs
by James Michels 04 Aug '16

04 Aug '16

Hello, I want to add an iSCSI based storage domain. For that I add a domain on the Storage tab with one of the IPs (say 10.10.10.1), but for failover purposes I'd like to use multipath to add a failover IP so if the first one fails, LUNs can be reached via the second (say 10.10.10.2). How can this be done in oVirt 4.0.1? I have not seen a way how to add the second IP for multipath purposes. Thank you James
