Good morning folks, and thank you in advance.
I am working on migrating my oVirt backing store from NFS to iSCSI.
oVirt Environment:
oVirt Open Virtualization Manager
Software Version:4.4.4.7-1.el8
TrueNAS environment:
FreeBSD truenas.local 12.2-RELEASE-p11 75566f060d4(HEAD) TRUENAS amd64
The iSCSI share is on a TrueNAS server, exposed to user VDSM and group 36.
oVirt sees the targeted share, but is unable to make use of it.
The latest issue is "Error while executing action New SAN Storage Domain: Volume Group block size error, please check your Volume Group configuration, Supported block size is 512 bytes."
As near as I can tell, oVirt does not support any block size other than 512 bytes, while TrueNAS's smallest OOB block size is 4k.
I know that oVirt on TrueNAS is a common configuration, so I expect I am missing something really obvious here, probably a TrueNAS configuration needed to make TrueNAS work with 512 byte blocks.
Any advice would be helpful.
