Hello

After updating to Unraid v7.2 (stable), file transfers from my Windows 10 VM (running on Proxmox) to the Unraid server consistently fail with an error, regardless of file size. This issue did not occur on previous Unraid releases.

Interestingly, the transfer succeeded once immediately after restarting the Windows VM, even for files exceeding 4 GB. Subsequent attempts reproduced the error.

Has anyone else encountered this behavior on v7.2?

This file is 4.2GB

This file is 18.5KB

I suspect I know what the issue is, but to confirm, please post the diagnostics.

Having same issue here as well, on 7.2. What happened to me is I added a new ZFS cache pool, then changed my shares to use the new cache pool. When mover runs, it remove the share folder which then causes the issues. I can manually create the folder again but mover just removes it on next run. I also tried to manually create the dataset but again mover kills it. The work around is to manually create the folder\dataset back after mover runs.

This should be fixed for the next release; the workaround for now is to type zfs mount -a

Just to be clear, I have not changed any settings or configurations from previous UnRaid versions. @phunky1 is experiencing a different isolated issue.

It is what I suspected; it affects some users when using a zfs pool as primary storage, workaround for now is to do a zfs mount -a

The last info I have is that LT was planning to release a 7.2.1-rc.1 with this and some other fixes this week. This would allow the affected users to confirm it resolves the issue, since I and LT cannot reproduce it, and not for a lack of trying on my part, and if all looks good, then release 7.2.1 stable a week or so later.

I can confirm the zfs mount -a works.

7.2.1-rc.1 is out, and it should resolve this issue, please retest.

@JorgeB Had the same issue on W11 and your command resolved it. Cheers. Let me know if you want diagnostics or anything else.

You can update to 7.2.1-rc.1 to confirm if it's fixed there; it should be.
