Shared and local storage, together
by duparchy＠esrf.fr 01 Feb '24

HI, We running some VMs from local storage. These are VMs for managing and monitoring tools such as Dell Storage Manager. So we don't want them to be stored in the shared storages they are managing and monitoring.... If something goes wrong on either the storage or the ISCSI network we want those VM to be up and running. Any way to enable both shared storages and some local storage in a cluster ? For the shake of using a host most efficiently and not for only a couple of VMs ?.

Cannot remove Snapshot. The VM is during a backup operation.
by and＠missme.ro 30 Jan '24

Hello! Running ovirt Version 4.5.5-1.el8 I had an issue with the iscsi server during the backup and I have two VMs that cannot be backed up anymore by Veeam. In the ovirt event log i have the following errors: Snapshot 'Auto-generated for Backup VM' creation for VM 'dns-a' has been completed. VDSM ovirt1-02 command StartNbdServerVDS failed: Bitmap does not exist: "{'reason': 'Bitmap does not exist in /rhev/data-center/mnt/blockSD/b2fa3469-a380-4180-a89a-43d65085d1b9/images/6a4de98a-b544-4df8-beb1-e560fd61c0e6/cdb26b8b-c447-48de-affa-d7f778aebac7', 'bitmap': '12d2fb20-74da-4e63-b240-f1a42210760c'}" Transfer was stopped by system.

The error on the Veeam backup proxy: dns-a: Unable to create image transfer: Reason: 'Operation Failed', Detail: '[]' When trying to delete the snapshot from the administration interface I receive the following error in the web interface (and nothing gets logged in the event log) Cannot remove Snapshot. The VM is during a backup operation. How should I go about fixing this issue?

HE Storage Domain Path Config Setting - Where?
by Matthew J Black 30 Jan '24

30 Jan '24

Hey Guys, Quick Q: In which file (on a Hosted-Engine or Hosted-Engine Host) is the configuration for the path to a Storage Domain kept - in particular, the "hosted-engine" Storage Domain? I've got something "funny" going on: the logs (as far as I can see) are reporting that 2 of my 3 HE-Hosts can't connect to the HE Storage Domain (but don't explain why), and the OVE GUI is reporting an "odd" (ie incorrect; non-existent) path to the HE Storage Domain. Via CLI I have confirmed that all three HE Hosts *can* reach (ie have the correct "findmnt" mappings) to the HE Storage Domain's actual file location, and I can't locate the "ghost" HE Storage Domain path or its config setting anywhere - so I don't even know if that's the issue, but I'd like to eliminate it from my trouble-shooting process. Anyway, if someone could get back to me, please, I'd really appreciate it. Cheers Dulux-Oz

Forbid hosts/nodes from assembling a soft-raid that was created inside a VM
by Vladislav Solovei 27 Jan '24

27 Jan '24

When I create a soft-raid (md-raid) inside a virtual machine (yes, sometimes it's necessary to do this to get a disk inside the VM with a capacity of more than 8TB), the host/node detects this array and assembles it automatically. I tried adding the parameter 'raid=noautodetect' to the kernel boot parameters, but it doesn't help. Is it possible to prevent hosts from doing this? :)

Low confirmed free space on gluster volume
by Jonas 27 Jan '24

27 Jan '24

Hello list I am regularly getting the following error on a Gluster volume hosted on a three node hyperconverged oVirt-Cluster: Warning! Low confirmed free space on gluster volume tier1-owncloud-users-01 This volume is configured with 3TiB (2.5TIB used) and is used as the name implies to store data of an ownCloud instance. It is not used as a storage domain in oVirt. I don't really want to resize the volume just to make the warning go away. While clicking through the oVirt web interface i found the configuration "Warning Low Confirmed Space Indicator" in the advanced parameters of the storage domains but did not find any similar setting in the configuration of the gluster volumes. Do you know of way to configure this setting for a gluster volume which is not used as a storage domain? Thank you Jonas

Change Hosted Engine VM MAC address
by Sergei Panchenko 26 Jan '24

26 Jan '24

Good morning, colleagues! Due some network issues I need to change HostedEngine VM MAC address. The additional diffeculty is unaccessebility of the HE Web-interface via the network (the cause of - those network issues -)). Is there any way to change the HE vNIC's MAC using command line (on the host where HE VM works or on the HE VM)? Thanks in advance, Sergei.

Need help again, new issue with VM import
by Michaal R 24 Jan '24

24 Jan '24

I have a VM that's a little over 4TB in size that won't import for whatever reason. I've tried changing the export from the streaming disk format to a flat vmdk,thinking that might be it, but it didn't work. I've gone through the OVF and don't see anything that stands out. Same for the logs, I see where it's having issues importing the 4TB drive from the VM, but I can't decipher the error messages well enough to know how to fix it. The drives had chkdsk run on them before they were exported, and the VM was cleanly shut down, so I don't understand what the issue is. Not even sure at this point how to run a filesystem repair on the vmdk, in case the export corrupted something. And I can't export it directly from ESXi either, for some reason. Each attempt fails with an unspecified error. Below is a snip from the import log where it's reading the drives. It has one of the first errors: [ 2.492229] scsi host0: Virtio SCSI HBA [ 2.501365] scsi 0:0:0:0: Direct-Access QEMU QEMU HARDDISK 2.5+ PQ: 0 ANSI: 5 [ 2.504080] scsi 0:0:1:0: Direct-Access QEMU QEMU HARDDISK 2.5+ PQ: 0 ANSI: 5 [ 2.506035] scsi 0:0:2:0: Direct-Access QEMU QEMU HARDDISK 2.5+ PQ: 0 ANSI: 5 [ 2.540737] sd 0:0:0:0: Power-on or device reset occurred [ 2.540790] sd 0:0:1:0: Power-on or device reset occurred [ 2.540899] sd 0:0:2:0: Power-on or device reset occurred [ 2.541130] sd 0:0:0:0: [sda] 8589934592 512-byte logical blocks: (4.40 TB/4.00 TiB) [ 2.541168] sd 0:0:2:0: [sdc] 8388608 512-byte logical blocks: (4.29 GB/4.00 GiB) [ 2.541319] sd 0:0:2:0: [sdc] Write Protect is off [ 2.541391] sd 0:0:0:0: [sda] Write Protect is off [ 2.541592] sd 0:0:2:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 2.542019] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 2.544060] sd 0:0:2:0: [sdc] Attached SCSI disk [ 2.545294] sd 0:0:1:0: [sdb] 251658240 512-byte logical blocks: (129 GB/120 GiB) [ 2.545437] sd 0:0:1:0: [sdb] Write Protect is off [ 2.545966] sd 0:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 2.551250] sdb: sdb1 sdb2 [ 2.556698] sd 0:0:1:0qemu-nbd: Disconnect client, due to: Failed to send reply: reading from file failed: Invalid argument : [sdb] Attached SCSI disk qemu-nbd: Disconnect client, due to: Failed to send reply: reading from file failed: Invalid argument qemu-nbd: Disconnect client, due to: Failed to send reply: reading from file failed: Invalid argument [ 2.618883] sd 0:0:0:0: [sda] tag#157 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=0s [ 2.618890] sd 0:0:0:0: [sda] tag#157 Sense Key : Aborted Command [current] [ 2.618892] sd 0:0:0:0: [sda] tag#157 Add.
