Cannot delete share: device or resource busy

[jacquesgalore]

Hi all -

 

I'm encountering an odd error. I have a share called `Time Machine - Jacques` located on `/mnt/disk1/`. I am trying to delete it, but unraid will not allow it:

What happens:

1. If you try to Delete, rename or change in the GUI it "processes" but nothing happens
2. Krusader will not let you delete
3. In the terminal, `rm -rf <directory>` returns "Cannot remove device or resource busy"

 

Details:

1. There is nothing in the share (confirmed in terminal using ls -alh)
2. The permissions are identical to other shares (confirmed in terminal)
3. There are no processes running (confirmed using lsof | grep)
4. There are no loops running on it (confirmed using losetup)
5. I've run in Safe Mode and stopped all Containers and VMs
6. Disk Check ran and came back normal

 

Questions:

1. Ideas or recommendations?
2. Can I delete without mounting the array?

 

Thanks

I have been able to delete this now (once) via umount, but now the share re-appears every time I reboot.

 

The same thing happens with renames and any settings. Upon reboot, the "Time Machine - Jacques" is back.

This appears to be the root of the issue in the boot logs.

I was able to solve this by:

1. Unmounting the share

2. Using `zfs destroy -r` instead of `rm -rf`

 

It appears that `rm -rf` is "queueing" the command but upon boot the changes are not successful.

 

By using zfs directly I was able to circumvent this.

I have the same issue, how do I unmount the share?

 

[Verpz]

I get an error saying it is already unmounted. Still says device or resource is busy

I have the same issue (apparently) but it's a pool and can't be accessed (as far as I know) without mounting the array.
