[ovirt-users] Re: oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious

FYI the fix is to check the "Disabled Physical Block Size Reporting" box in the extent window. Note in testing this I had to delete the extent and create a new one, toggling the switch on and then restarting the iscsi service didn't seem to do it, maybe the client cached something.

[ovirt-users] Re: oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious

Thank you both. This is certainly good information. If I'm going to jump to a different backing store, now it's the time to do it. But I'm not going to jump simply for the sake of jumping. The nfs issue was reproduced at redhat on a storage appliance other than truenas (QNAP I believe), so I am

And as a complement for the last message, having 500GB of SLOG is almost irrelevant. SLOG isn’t a write cache mechanism, it’s a write offload one. The maximum size used by SLOG is equal to the maximum transaction group that you could have. I don’t know the maths to measure this for you, but I

David do yourself a favor a move away from NFS on TrueNAS for VM hosting. As a personal experience hosting VMs on NFS may cause your entire infrastructure to be down if you change something on TrueNAS, even adding a new NFS share may trigger a NFS server restart and suddenly all your VMs will

[ovirt-users] Re: oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious

The cluster is on nfs today, with 500gb NVME SiLOG. Under heavy IO the vm's are thrown into paused state instead of iowait. A prior email chain identified a code error in qemu, with a repro using nothing more than DD to set 2 gb on the virtual disk to 0's . Since the point of the system is to

[ovirt-users] Re: oVirt + TrueNAS: Unable to create iSCSI domain - I am missing something obvious

TrueNAS supports 512 bytes block in iSCSI. Check at: Sharing => iSCSI => Extent. Edit your Extent configuration and look for Block Size. I’m running three different oVirt DCs with TrueNAS and iSCSI in all of them. Sent from my iPhone On 2 Mar 2022, at 11:49, Nir Soffer wrote:  On Wed, Mar
