Hi,
is there any documentation about mapping usernames, user-ids,
groupnames and group-ids between hosts sharing the same CephFS storage?
Thanx for any hint,
Renne

Hi,
I’m facing this issue, too. I haven’t found any satisfying mapping solution so far. Now
I’m considering deploying FreeIPA to unify the uid and gid on every host. CephFS does not
store user names and group names in the file system as far as I know.

i guess this is a bit outside of the scope of ceph … as with every
distributed environment, basically you'll have to make sure that
numerical uids/gids get resolved to identical user/group names on every
host involved. an appropriate name service switch configuration with a
suitable backend (pam_ldap, winbind, …) is the way to go.

CephFS is only recording the numeric user ID and group ID in the
directory entry. It is up to the client to map that onto user name and
group name.
What you use for consistent mappings between your CephFS clients is up
to you. It could be NIS, libnss-ldap, winbind (Active Directory) or any
other method that keeps the passwd and group files in sync.
