Everytime I try to reduce a share size by 2TB I get this error:
Traceback (most recent call last):
File “/opt/rockstor/src/rockstor/rest_framework_custom/generic_view.py”, line 41, in _handle_exception
Is that what this error is referring to?
Share size enforcement is temporarily disabled due to incomplete support in BTRFS. Until this status changes, the effective size of a Share is equal to the size of the Pool it belongs to.

@nandor Hello again.
This is an odd one, we haven’t had a quota / qgroups issue reported for a while now. Do you have quotas disabled / enabled and can you confirm the exact Rockstor version via a:
yum info rockstor
just in case as we have a bug when moving from testing to stable where it can show available rather than installed version.
A note on the quoted note, yes we don’t as yet enforce quotas as they are only just coming of age and we need more the Tumbleweed age of kernels before we can use them to enforce space usage anyway.
Hope that helps.

@nandor Thanks for the info.
So given our current ‘non imposed’ quota arrangement this is mostly a cosmetic issue but does look like a bug. Does the same error occur post a reboot. Rockstor re-calculates a bunch of stuff on each boot-up and it may be that this issue is transient to your particular boot up. I.e. not having reboot since a major Rockstor upgrade for example. Let us know if that has any bearing on this issue and if not then we should create an issue detailing what we know of this thus far.
Thanks for the report and for helping to support Rockstors development.

Rebooted and no change. I didn’t do anything fancy to get this to happen. I just simply created 1 Pool and a few shares and then tried to later resize one of those shares. Is there anyone who knows more than I do about btrfs that can tell me what this command does exactly so I can try to replicate it in the CLI to debug?
Edit one thing I did that was causing problems before is that I made minutely snapshots and told it to save up to 750 of them. I was doing this for testing and forgot and left it that way. 2 days later it had tried to mount > 500 snapshot file systems and was causing all sorts of havoc. I deleted all the snapshots and created a reasonable interval to clean it up. Is it possible it created a ton of quota groups? I have a lot of them, though admittedly I dont know what they mean:
[root@san-nas ~]# btrfs qgroup show /mnt2//MainStorage
qgroupid rfer excl

Is there a way to cleanup unused qgroups?

Fix
I was able to fix this by disabling / re-enabling Quotas on the storage pool. When I now look at the qgroup list it is much more reasonable:
qgroupid rfer excl max_rfer
-------- ---- ---- --------
0/5 0.00B 0.00B none
0/257 1.82TiB 1.82TiB none
0/258 1.42GiB 1.42GiB none
0/259 0.00B 0.00B none
0/354 19.36GiB 19.36GiB none
0/8560 2.79GiB 2.79GiB none
0/8561 32.00KiB 32.00KiB none
2015/1 0.00B 0.00B none
I suspect this is a cleanup issue where old qgroups are never being pruned but I don’t acutally understand how btrfs works so I can’t be certain.

@nandor Well done. Yes I was going to suggest a disable / re-enable. But you’ve got their first.
qgroupid’s beginning with 0 are auto created by btrfs itself, but only if quotas are enabled if I remember. However the ones beginning with 2015 are Rockstor created. And Rockstor has to manage these as it goes along. When quotas are disabled qgroupid info is lost. When quotas are re-enabled Rockstor has to re-create them on the fly. It’s actually quite involved and we have for sure more work to be done there.
Once upon a time, Rockstor was absolutely dependant upon quotas (still in in the now older testing channel). Then docker-ce developed a very un-helpful habit of disabling quotas before we were ready to support this state. As a result we had to move quickly to add quota disabled capabilities. This was a tall order but we’ve just about done it. There are most likely outstanding bugs in our quota related code and you may have hit one here.
Glad you got this sorted and thanks for sharing your findings.
Note however that it can take quite some time to re-establish quota info once it is turned back on again: this depends on pool (btrfs volume) size/use and the number of shares/snapshots/clones (btrfs subvols).

Took about 10 mins to re-establish but my hardware is pushing 3Gb/s on read/write and closer to 6 on read only.
