Hey Kenneth,
We encountered this when the number of strays (unlinked files yet to be
purged) reached 1 million, which is a result of many many file removals
happening on the fs repeatedly. It can also happen when there are more than
100k files in a dir with default settings.
You can tune it via
buy us enough time to move to bluestore.

start/stop all osds manually. this was ok for us, particularly since we
didn't intend to run that state for a long period, and eventually upgraded
to jewel and soon to be luminous. In your case, since trusty is supported
in luminous I

hey guys.
wondering if anyone else has done some solid benchmarking of jewel vs
luminous, in particular on the same cluster that has been upgraded (same
cluster, client and config).
we have recently upgraded a cluster from 10.2.9 to 12.2.0, and
unfortunately i only captured results from a single

Hi all,
I am curious what practices other people follow when removing OSDs from a
cluster. According to the docs, you are supposed to:
1. ceph osd out
2. stop daemon
3. ceph osd crush remove
4. ceph auth del
5. ceph osd rm
What value does ceph osd out (1) add to the removal process and why is
inb=121882KB/s, maxb=121882KB/s,
mint=860318msec, maxt=860318msec
Disk stats (read/write):
dm-1: ios=0/2072, merge=0/0, ticks=0/233, in_queue=233, util=0.01%,
aggrios=1/2249, aggrmerge=7/559, aggrticks=9/254, aggrin_queue=261,
aggrutil=0.01%
sda: ios=1/2
onf and rerunning the tests is sufficient.

Hi ceph-users,
Hoping to get some help with a tricky problem. I have a rhel7.1 VM guest
(host machine also rhel7.1) with root disk presented from ceph 0.94.2-0
(rbd) using libvirt.
The VM also has a second rbd for storage presented from the same ceph
cluster, also using libvirt.
The VM boots
