[ceph-users] nfs-ganesha / cephfs issues

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)?
