Hi,
While trying to balance cluster over night I have hit "osd full"
treshold on one osd.
Now I actually cannot start it, because ir says xfs file system is full.
# df -h /dev/sdb1
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 373G 373G 100K 100% /var/lib/ceph/osd/ceph-0
How to recover from this? Full osd sure is the situation to escape(red
flags in doc for that), whilst it should not mean lost osd, right?
And some debugging output follows, probably situation is not handled
best way by binary?
from /var/log/ceph/ceph-osd.0.log when starting osd.0
