It only happens when there is a subvolume is in the subvolume group.


It should say, empty the subvolume group before remove it which causes customer confusion.

Neeraj, please create a tracker and link it in this bz.

Ceph Dashboard shows the error message we get from the respective call which is made to remove the subvolume group. Since we get the message as `error in rmdir /volumes/jul_group` we show that in the UI. Could you please attach mgr logs to the bz at the time of removal to see what are all the messages that we get from the volumes module? Based on that we can decide whether the fix should go in Dashboard or the Volume module.

In any case, this could be an RFE so moving it out to 7.1. If we have the fix earlier, maybe it could be targeted to 7.0z1

Hi,
I did reproduce the issue and found that we are not catching `ENOTEMPTY` error
in volumes plugin and that's why we are getting the generalised message for rmdir
instead of a customized one. Will create a tracker under CephFS.

It seems that the issue is not from Ceph-dashboard, but from volumes plugin.
@Nizamudeen, pls re-assign to me if you are ok!
