I have two test clusters running Bobtail (0.56.4) and Ubuntu Precise
(12.04.2). The problem I'm having is that I'm not able to get either
of them into a state where I can both mount the filesystem and have
all the PGs in the active+clean state.
It seems that on both clusters I can get them into a 100% active+clean
state by setting "ceph osd crush tunables bobtail", but when I try to
mount the filesystem I get:
mount error 5 = Input/output error
However, if I set "ceph osd crush tunables legacy" I can mount both
filesystems, but then some of the PGs are stuck in the
"active+remapped" state:
# ceph -s
health HEALTH_WARN 29 pgs stuck unclean; recovery 5/1604152 degraded (0.000%)
monmap e1: 1 mons at {a=172.16.0.50:6789/0}, election epoch 1, quorum 0 a
osdmap e10272: 20 osds: 20 up, 20 in
pgmap v1114740: 1920 pgs: 1890 active+clean, 29 active+remapped, 1
active+clean+scrubbing; 3086 GB data, 6201 GB used, 3098 GB / 9300 GB
avail; 232B/s wr, 0op/s; 5/1604152 degraded (0.000%)
mdsmap e420: 1/1/1 up {0=a=up:active}
Is any one else seeing this?
Thanks,
Bryan
