If you have a backfillfull, no pg's will be able to migrate.
Better is to just add harddrives, because at least one of your osd's is
to full.
I know you can set the backfillfull ratio's with commands like these
ceph tell osd.* injectargs '--mon_osd_full_ratio=0.97'
ceph tell osd.* injectar
I've heard of the same(?) problem on another cluster; they upgraded
from 12.2.7 to 12.2.10 and suddenly got problems with their CephFS
(and only with the CephFS).
However, they downgraded the MDS to 12.2.8 before I could take a look
at it, so not sure what caused the issue. 12.2.8 works fine with t

I have a process stuck in D+ writing to cephfs kernel mount. Anything
can be done about this? (without rebooting)
CentOS Linux release 7.5.1804 (Core)

Hi,
to be more precise, netstat table looks as in the following snippet:
tcp 0 0 10.10.200.5:6815 10.10.25.4:43788 ESTABLISHED
51981/ceph-osd
tcp 0 0 10.10.15.2:41020 10.10.200.8:6813 ESTABLISHED

tcp 0 0 10.10.15.2:48724 10.10.20
check /proc//stack to find where it is stuck

Dear Ceph Users,
We have set up a cephFS cluster with 6 osd machines, each with 16 8TB
harddisk. Ceph version is luminous 12.2.5. We created one data pool with
these hard disks and created another meta data pool with 3 ssd. We created
a MDS with 65GB cache size.
But our users are keep complaining

Hi Yan Zheng,
1. mds cache limit is set to 64GB
2. we get the size of meta data pool by running `ceph df` and saw meta data
pool just used 200MB space.
Thanks,

Hi all, looks like I might have pooched something. Between the two nodes I
have, I moved all the PGs to one machine, reformatted the other machine,
rebuilt that machine, and moved the PGs back. In both cases, I did this by
taking the OSDs on the machine being moved from “out” and waiting for hea
