    @poddingue Thanks for looking into this! I checked the bulk "Reconnect to all hosts" action as well, and you're right — it doesn't work either. It only works if I select a single SR, open its page, and use the "Reconnect to all hosts" action from there.

    @ludalm13 the PCI-DSS Requirement 10 part helps your case, I think, because it turns this from a nice-to-have into something an auditor will ask for. You're not the only one asking, either. The Feeder request @dknight-bg linked is at four votes now. I'll also point the XO backend folks at the PR directly, a tag in a forum thread is easy to miss in a busy week.

    Just as an update on this. Did get the migrations working. Still haven't gotten the backups working. Pool is still stable otherwise. Have managed to get backups by using Veeam so it's not to much of a problem.

    Hi, This was fixed in Latest. But if you need to stay on Stable, you can open a ticket to have a patch.

    For anyone else who steps through this, I've also installed the latest xen-guest-agent with the below process. Repeat for each host in the environment, 1 at a time from your Helper VM. ### ssh into your helper ### oc debug node/fedora-cmp-1/2/3 chroot /host cd /var/tmp curl -LO https://gitlab.com/xen-project/xen-guest-agent/-/jobs/6041686376/artifacts/raw/RPMS/x86_64/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm sudo rpm-ostree install /var/tmp/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm mkdir /var/tmp/xga && cd /var/tmp/xga rpm2cpio ../xen-guest-agent-0.4.0-0.fc37.x86_64.rpm | cpio -idmv ### From your helper... DRAIN YOUR WORKERS ### oc adm drain fedora-cmp-1/2/3 --ignore-daemonsets --delete-emptydir-data ### log back into fedora-cmp-1/2/3... ### sudo systemctl reboot ### from helper ### oc adm uncordon fedora-cmp-1/2/3 ### login to fedora-cmp-1/2/3 ### chroot /host sudo systemctl enable --now xen-guest-agent And then from XO this is what your VMs will look like.

    @mrnaz look for the (first) error in your terminal where you execute the script to upgrade. Probably you need to upgrade the yarn or node version.

    @mauzilla I've done so that I have two separate backup jobs incremental every 4 hours, with exception on weekends. Retention usually 8 days weekly full backups, zstd compression, every Sunday night. This way we have a separate backup from the incremental chain. We also are able to do more maintenance jobs on the nfs server etc during the off hours on the weekend.

    @olivierlambert Thanks, We had been looking at Terraform so I guess we'll keep heading down that path for the time being.

    @vmpr Not much, this is a system issue which means that it's either due to your NFS server or to the connection between your XO and the NFS server. First, try to unmount the share and restart xo-server, if it keeps happening, restart the whole machine on which XO is. If that does not help, you should mount the share manually and do some tests directly on it.

    Most users are relying NFS shares. However, we are open to build something for tapes. The problem is: we have no knowledge on that technology nor have any tape system in our lab. If there's enough traction for this, or even sponsored dev to do it, we'll be happy to work on that!

    @olivierlambert XO does not test the full VHD structure because that would be too long, but does check both the begining and the end of the file (and all other VHDs in the chain) before each backup to make sure the files were not truncated. For full backup we are using a simple heuristic to attempt to validate XVA files, but it's very basic and unfortunately it does not applies to compressed files.

    For the installation of the correct node version for some major Linux distributions please follow the installation instructions in this readme: https://github.com/nodesource/distributions/blob/master/README.md The Ubuntu section worked for me.

    @julien-f I believe that you already updated the docs, but that occurred after the postings above. You may want to review the section discussing forever-service to be sure it doesn't need modified.

    @s-pam i'd say use them, always use the. Only a few KB of space and could be every handy. We have 3 servers in the pool so overlooked requirement for full pool recovery. (p.s we didn't fail, it's during DR testing it was flagged) we had the backups on already and if this had been a real issue, would have saved a lot of bacon!! turn it on ! (and check you can get it without a running XOA for quicker restore in full meltdown.)
