Hi @aremiaskfa ,

This is, I’m afraid, @phillxnet’s expertise so I’m unsure of the root cause of the issue here. In the meantime, you should be able to workaround this by disabling quotas (they are currently not enforced).

See a similar thread below:

Error running a command. cmd = /usr/sbin/btrfs qgroup assign 0/258 2015/17 /mnt2/storage_1. rc = 1. stdout = ['']. stderr = ['ERROR: unable to assign quota group: File exists', '']

@acd Hello again. Could you say what version of Rockstor you are experiencing this with. Note that we don’t currently enforce share sizes so the Web-UI indication of a share size is basically a cosmetic currently. There were early quota maturity issues that have mostly now gone I believe so we can re-address this enforcement in time. But currently we have some more pressing issues that are taking the majority of development time available unfortunately. You could try, in the mean time, just …

@aremiaskfa I found that for resizing currently the quotas need to be turned on. I usually have them turned off. When I wanted to perform a resizing some time ago (on 4.1.0-0), I needed to turn quotas back on for the pool where I wanted to perform a resizing of a share.

For some reason, in my case the change in the WebUI didn’t hold, so I had to do it at the command line…

btrfs quota enable /mnt2/<volume_name>
and then after resizing or creating a new share, I disabled them.

I just tried it on my 4.6.9-1 installation … and this time it didn’t complain about it, so not sure whether I did anything different or something has changed, but I am also running on the Linux: 6.3.1 now (backport for Leap 15.4) so a new version of btrfs-progs might have taken care of that problem …

I guess, if currently have quotas on, then @Flox 's recommendation is the one to follow, and if you currently have them off, then you can see whether following mine addresses it. But as mentioned above, since we’re not enforcing quotas the resizing would be only for visual/cosmetic purposes at this moment.

We probably need to look further into this …

to further add to this, I am referencing another forum posting for which we addressed new share generation (I completely forgot that I had posted that originally)

Rockstor 4.5.7 Cannot create share with quotas disabled on pool

Not sure, whether this was discussed already in the past (my search didn’t yield any relevant results), but on Rockstor 4.5.7 during share creation on a pool for which the quotas are disabled, the UI comes back with an error that prevents it from doing so: Traceback (most recent call last): File "/opt/rockstor/src/rockstor/rest_framework_custom/generic_view.py", line 41, in _handle_exception yield File "/opt/rockstor/src/rockstor/storageadmin/views/share.py", line 206, in post add_share(pool, s…

and that scenario was fixed in Release Candidate 4.5.8-0
