Dear CephFS experts
Before it was possible to mount a subtree of a filesystem using
ceph-fuse and -r option.
In invernalis, I am not understanding how that is working, and I am only
able to mount the full tree. 'ceph-fuse --help' does not seem to show
that option although 'man ceph-fuse' says it should work.
Basically, this works:
# /usr/local/ceph920/bin/ceph-fuse -m MON_IP:6789 /coepp/cephfs
ceph-fuse[7826]: starting ceph client
2015-12-15 01:00:03.231332 7f70c2ffc720 -1 init, newargv =
0x7f70c655a840 newargc=11
ceph-fuse[7826]: starting fuse
# ll /coepp/cephfs
total 2
drwxr-xr-x 1 root root 0 Dec 15 00:45 adl
drwxr-xr-x 1 root root 0 Dec 15 00:45 mel
drwxr-xr-x 1 root root 0 Dec 15 00:47 share
drwxr-xr-x 1 root root 0 Dec 15 00:44 syd
But this doesn't
# ceph-fuse -m MON_IP:6789 -r /coepp/cephfs/syd /coepp/cephfs
ceph-fuse[8906]: starting ceph client
2015-12-15 01:02:12.897012 7ff838e4d720 -1 init, newargv =
0x7ff83d00a870 newargc=11
ceph-fuse[8906]: ceph mount failed with (2) No such file or directory
ceph-fuse[8904]: mount failed: (2) No such file or directory
Is it just me not fully understanding how to properly do it?
TIA
Goncalo
