Hello, I recently use cephfs in version 17.2.6 I have a pool named "*data*" and a fs "*kube*" it was working fine until a few days ago, now i can no longer create a new subvolume*, *it gives me the following error: Error EINVAL: invalid value specified for ceph.dir.subvolume
here is the command used: ceph fs subvolume create kube newcsivol --pool_layout data
from what I understand it seems that it creates the subvolume but immediately puts it in the trash !? here is the log : 2023-06-23T08:30:53.307+0000 7f2b929d2700 0 log_channel(audit) log [DBG] :
