After I tried to copy some files into a rbd device I ran into a "osd full"
state. So I restarted my server and wanted to remove some files from the
filesystem again. But at this moment I cannot execute "rbd map" anymore and I do
not know why.
This all happened in my testing environment and this is the current state with
'ceph status'
health HEALTH_ERR
2 full osd(s)
monmap e1: 1 mons at {test1=10.0.0.141:6789/0}
election epoch 1, quorum 0 test1
osdmap e69: 2 osds: 2 up, 2 in
flags full
pgmap v469: 100 pgs, 1 pools, 1727 MB data, 438 objects
3917 MB used, 156 MB / 4073 MB avail
100 active+clean
strace reports this before 'rbd map pool/disk' hangs

setsockopt(3, SOL_SOCKET, SO_PASSCRED, [1], 4) = 0
open("/sys/bus/rbd/add_single_major", O_WRONLY) = 4
write(4, "10.0.0.141:6789 name=admin,key=c"..., 61
Any idea why I cannot access the rbd device anymore?
