Hello,

I just upgraded from 7.2.4 -> 7.3.1 today. However after upgrading all my non-default shares as well as my Docker configurations were wiped. I had to do a setup wizard when I first booted into 7.3.1 so maybe that has to do with it. I did not do anything else except do a standard upgrade. The disks themselves mount fine just the shares are missing including array and cache.

The syslog shows emhttpd calling getxattr on /mnt/user/<share> paths during initialization, getting EOPNOTSUPP (errno 95 — filesystem doesn't support xattrs), and then skipping the shfs mount entirely.

emhttpd: error: malloc_share_locations, 8649: Operation not supported (95): getxattr: /mnt/user/syslogs

emhttpd: Starting services...

Some things I have tried:

• Downgrade to 7.2.4 - same issue

• Disabled some of my plugins

• Rebooted system

• Nothing with ZFS was created

From what I can tell my files and Docker is still there but something with my system configuration is not picking them up.

I have attached the diagnostics.

There's something creating this folder before the array is started, this is not allowed, /mnt/user cannot be used for any custom stuff, or the user shares won't work.

Hi,

I'm just replying here to share the fact that I just experienced the exact same issue: I upgrade from 7.2.5 to 7.3.1 and all my shares and Docker containers have been wiped. I can still see the data on the disks (/mnt/diskX) but the whole Docker container settings (with the Docker networks, etc.) and the shares are empty. I also went through the wizard and I wonder whether this has an effect. But in the end it detected my current setup and just confirmed it so I thought it was alright.

Here is my diagnostics too.

I opened a ticket with the Unraid team and I hope they can help us restore our shares and Docker containers in an easy way. I'll reply here if I get any response from them.

It's the same issue as above; you have something creating this folder before the array is started:

Thank you very much @JorgeB !

With your reply, I removed the offending line that was trying to create a directory under /mnt/user at boot time and after a restart, my server restored all the shares and Docker containers! \o/

Since I very recently added the offending line to my boot script and I can't remember if I had rebooted my server after the change, I am not certain this is a new constraint with 7.3 or if that always would have been an issue though.
In any case, thanks a lot for your help since it allowed me to fix the issue even before the Unraid official team can respond (I'm guessing the time difference means they're currently asleep).

Have a great one!

It has always been a constraint that only the system should create folders under /mnt/user so that probably means you did not get around to rebooting the server after changing your script.
