I think engine.log would be a good place to start, it would likely tell us on which host there's a problem (if there is one) On Sun, Apr 25, 2021 at 10:22 AM Matthew.Stier(a)fujitsu.com <Matthew.Stier(a)fujitsu.com> wrote: > > Which logs, on which hosts should I be looking through? > > I have a hint of that from my research, but all 121 hosts are up and running. > > -----Original Message----- > From: Benny Zlotnik <bzlotnik(a)redhat.com> > Sent: Sunday, April 25, 2021 1:53 AM > To: Stier, Matthew <Matthew.Stier(a)fujitsu.com> > Cc: users(a)ovirt.org > Subject: Re: [ovirt-users] Attempting to detach a storage domain > > What do the logs say? > This usually means that not all hosts were able to disconnect from it > > On Sun, Apr 25, 2021 at 9:45 AM Matthew.Stier(a)fujitsu.com <Matthew.Stier(a)fujitsu.com> wrote: > > > > Ovirt: 4.3.10 > > > > Storage: iSCSI > > > > > > > > Problem: Attempting to place storage domain into ‘maintenance’ in preparation for detachment and destruction, has left it hung in a ‘Preparation for maintenance’ state. > > > > > > > > I have three storage domain I need to put into maintenance, detach and delete.

How to reduce load during create VM
by ovirt.org＠nevim.eu 26 Apr '21

26 Apr '21

Hi everyone, please, can you limit the "Create VM" process somewhere so that setting up quota does not load the server so much, especially storage when duplicating the template disk?

oVirt on GCP
by mario.gandara＠gmail.com 26 Apr '21

26 Apr '21

Hello, guys! I'm trying to deploy oVirt on GCP for the last two weeks. Someone did it on GCP using nested virtualization? My scenario is: One standalone oVirt Engine and two hosts. In the future I imagine to scale this solution. Thank you. Mário Gândara

Problem with ISCSI multipathing identifying faild path to a LUN every few seconds.
by Gal Villaret 25 Apr '21

25 Apr '21

Hi All, In the past few days, we have been having problems with hosts becoming unmanageable due to multipathd identifying false failed paths and VDSM crashing because of it. We were running version 4.4.1 and upgrading to 4.4.5(engine) and 4.4.6(nodes) seems to have resolved the VDSM. However, currently, we see that the multipathing events continue. From what we have observed, the events start in correlation to the host reporting on low swap space. The low swap space seems to be related to Commvault backup operation running. By running top on the host while a backup operation is running I can see swap being consumed to 100% although there is plenty of RAM available. After the multipath events start happening the only means of stopping it was to reboot the host. This is the warning in oVirt UI: Apr 24, 2021, 9:14:07 PM - Available swap memory of host Ovirt-Node2 [953 MB] is under defined threshold [1024 MB]. This is the first appearance of the multipath event in /var/log/messages: Apr 24 21:14:58 ovirt-node2 kernel: sd 21:0:0:9: [sdgi] tag#77 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE cmd_age=15s Apr 24 21:14:58 ovirt-node2 kernel: sd 21:0:0:9: [sdgi] tag#77 Sense Key : Aborted Command [current] Apr 24 21:14:58 ovirt-node2 kernel: sd 21:0:0:9: [sdgi] tag#77 <<vendor>>ASC=0xc1 ASCQ=0x1 Apr 24 21:14:58 ovirt-node2 kernel: sd 21:0:0:9: [sdgi] tag#77 CDB: Read(16) 88 00 00 00 00 00 79 ac 75 a0 00 00 06 00 00 00 Apr 24 21:14:58 ovirt-node2 kernel: blk_update_request: I/O error, dev sdgi, sector 2041345440 op 0x0:(READ) flags 0x4200 phys_seg 192 prio class 0 Apr 24 21:14:58 ovirt-node2 kernel: device-mapper: multipath: 253:20: Failing path 131:224.

Migration VM and Storage Domains
by LS CHENG 25 Apr '21

25 Apr '21

Hi I have a question about migrating VM's. If I have 2 VM and each VM is stored in separate Storage Domains can the VM migrate between physical hosts? Or the VM must be stored in the same Storage Domain? For example VM1 is stored in SD1 and runs in HOST-A VM2 is stored in SD2 and runs in HOST-B Can VM2 migrated to HOST-A? Thanks

What do the logs say?

Attempting to detach a storage domain
by Matthew.Stier＠fujitsu.com 25 Apr '21

25 Apr '21

Ovirt: 4.3.10 Storage: iSCSI Problem: Attempting to place storage domain into 'maintenance' in preparation for detachment and destruction, has left it hung in a 'Preparation for maintenance' state. I have three storage domain I need to put into maintenance, detach and delete. When I placed place the first, and smallest (100GB) into maintenance mode, it switched to 'Preparing for Maintenance', and has stuck there for hours. Early on, I was able to re-activate it, but I do want to remove for use somewhere else, and I want make sure I can remove it, before I try to do the same with two 11TB storage domains.
