    @Danp I was going to do the upgrade over the December / January Christmas break in Australia but that is when this issue became apparent so we didn't want to be making major changes until it was resolved. I note @anthoineb noted the first report was late August / September 2025 which was just before 8.2.1 reached EOL, so it would be a shame not to have a fix for it tested on 8.2.1 as it seems an upgrade to 8.3 would be unwise while we still have this issue?

    @laszlobortel since we are generating the stream sequentially, we though that there wasn't any real world gain. Also, if my understanding is correct using one thread means we will have only one process( + xo + nbdkit-vddk) processes , and we were trying to limit the risk of zombie process locking the disks , which was far too common with the previous code we'll do a quick test to ensure it does not beak anything and propose either a better default of a configuration option note that this will be a concurrency per disk, so VM with a lot of disk will put more pressure on the source

    Hi! ISO-SR over HBA/FC would be very nice, especially when migration form a SAN vmware-System to XCP-NG. One other thing is altering. Errors like "VM cannot be migrated" or similar should not be silent but should be very visible / even mailed to the admin. Another thing (could be cosmetical though) in my opinion is that a failed Rolling upgrade remains visible with a half fulled progress bar in the task-view. this is confusing.

    Large VM Migration fails, host has free disk - Storage_error

    I managed to do the migration by splitting over the two storages the remove system has. This made it work and I managed to move that one VM. However I still have a second one It's thick provisioned (LVM - never can remember the terms thin/thick). Offline isn't an option unfortunately since I need the services running, can't take if off for 15 hours. But since two of the services are docker containers, both having a separate disk of 500GB, I can make it work by setting up a two new systems and moving everything from the container there. Which would reduce the size by 1TB and make thing easier to manage. Was hoping I could finally upgrade the main xcp-ng last weekend.

    @Pilow Does disk show up after you do the snapshot? If it is able to do the snapshot there is a high chance it can boot up. So try booting up (and check for disk) and shut it down and do the snapshot at that time if the disk show up. It helps to boot up on the old v5 commit and check from that side too if you have both copy before the commit update. Yep I can confirm that snapshot doesn't always work. But using the older v5 that used to work before the update does get it showing up on the newer v5 commit if I go through whole snapshot, revert, etc. one of those case work.

    Tracked it down to it thinking there was a pool version mismatch... then when I tried to transition to a new master it would fail with Xmlrpc_client.Connection_reset ... digging deeper it was complaining that it couldn't restore from the wrong version. Lots of head banging later... I setup a backup for the pool metadata and forced the backup immediately. TADA... I can now change the master with no issues at all.

    Yes, there's a possible weird combo between XOSTOR and HA in some situations. Let me add @ronan-a or @dthenot in the loop. It's likely that XOA disconnection is just a visible symptom of something else. It's not ultra trivial to reproduce though.
