Mounting unionfilesystem fails. #29

Closed virtaj closed 5 years ago

virtaj commented 5 years ago

Trying omv 5.0.4-1 and unionfilesystem 5.0.

Creating unionfs through webui works ok and it creates correct entries to fstab. However mounting it fails. Unmount and mount again from terminal works. ` root@nas:~# cat /etc/fstab

All I can think is that it is trying to mount the mountpoint before the directory is created. I will have to look into it.

I know doesn't help... But I reboot after making changes

The saving grace about mergerfs is that it's path based, so it doesn't care if you unmount and remove a drive. Point is you don't have to modify Union fs to remove an external drive, though omv won't be happy until you reattach it

Rebooting does work but that wasn't necessary when creating new pools on OMV 4.x. So, something has changed that I would like to fix.

I'm experiencing similar problems, rebooting mounts the mountpoint again until I apply any new changes in the OMV then the mountpoint gets inaccessible yet again and I some errors because it cant access the mount.

Are you rebooting before you apply the changes? If so, reboot after you apply the changes. The initial problem in this issue is fixed in newer OMV 5.x versions. Changing the pool options without a reboot will not be "fixed".
