Cephfs does have repair tools but I wouldn't jump the gun, your metadata pool is probably fine. Unless you're getting health errors or seeing errors in your MDS log?
Are you exporting a fuse or kernel mount with Ganesha (i.e using the vfs FSAL) or using the Ceph FSAL? Have you tried any tests directly on a CephFS mount (taking Ganesha out of the equation)?

I have on luminous 12.2.1 on a osd node nfs-ganesha 2.5.2 (from ceph

get stalls.
I thought it was related to the amount of files of rsyncing the centos7
distro. But when I tried to rsync just one file it also stalled. It
looks like it could not create the update of the 'CentOS_BuildTag' file.
Could this be a problem in the meta data pool of cephfs? Does this sound
familiar? Is there something like an fsck for cephfs?
