NFS Ganesha export fails after adding Rados Gateway subusers

This document (7023860) is provided subject to the disclaimer at the end of this document.


SUSE Enterprise Storage 5.5
Ceph version 12.2.10 (or earlier).


After creating RGW (Rados GateWay) subusers, Ganesha NFS exports fail with:

ganesha.nfsd-xxxxxxx[main] create_export :FSAL :CRIT :Unable to mount RGW cluster for </path>.
ganesha.nfsd-xxxxxxx[main] create_export :FSAL :CRIT :Authorization Failed for user <user>
ganesha.nfsd-xxxxxxx[main] mdcache_fsal_create_export :FSAL :MAJ :Failed to call create_export on underlying FSAL RGW
ganesha.nfsd-xxxxxxx[main] fsal_cfg_commit :CONFIG :CRIT :Could not create export for (</dir>) to (</path>)


Upgrade to at least Ceph version 12.2.11 or until an upgrade is possible, temporarily remove the newly created subuser(s).


Due to a bug in versions prior to Ceph 12.2.11, verification was done against the first key listed with:

# radosgw-admin user info --uid <user_id>

which in some cases can be that of the subuser(s).
