I have built a couple of ceph test clusters, and am attempting to mount the
storage through ceph-fuse on a RHEL 6.4 VM (the clusters are also in VMs). The
first one I built under v0.80, using directories for the ceph OSDs (as per the
Storage Cluster Quick Start at
http://ceph.com/docs/master/start/quick-ceph-deploy/ ). The second is built
under v0.84, using the disks directly for OSDs. I have the keyring files for
each available on the client node, and copy in the appropriate one when I try
mounting.
The first cluster will mount with no problem, and I can read and write to it.
If I try to mount the second cluster instead (copying in the keyring file and a
ceph.conf with the appropriate mon node info), ceph-fuse gets as far as
"starting ceph client", and never gets any further. I could leave it there for
half an hour (ran the command and went to get lunch) and it never completes.
The status command shows each cluster as healthy.
