Hi Igor,
thanks for your reply.
To workaround it you might want to switch both bluestore and bluefs allocators
back to bitmap for now.
Indeed, setting both allocators to bitmap brought the OSD back online and the
cluster recovered.
You rescued my cluster. ;-)
Cheers

Is this cephcsi plugin under control of redhat?

How good is it at isolating tenants from each other? Can they see each

Huhhh...
Its unfortunate that every google search i did for turning off rbd cache,
specified "put it in the [client] section".
Doh.
Maybe this would make a good candidate to update the ceph rbd docs?
Speaking of which.. what is the *exact* syntax for that command please?
None of the below work:

As an open source project,
I guess I left out in my examples, where I tried rbd_cache as well, and failed
# rbd config global set rbd_cache false
rbd: invalid config entity: rbd_cache (must be global, client or client.)
So, while i am happy to file a documentation pull request.. I still need to
find the specific comman

I am happy to say, this seems to have been the solution.
After running
ceph config set global rbd_cache false
I can now run the full 256 thread varient,
fio --direct=1 --rw=randwrite --bs=4k --ioengine=libaio --filename=/dev/rbd0
--iodepth=256 --numjobs=1 --time_based --group_reporting --na
Huhhh..
It seems worthwhile to point out two inconsistencies, then.
1. the "old way", of ceph config set global rbd_cache false
doesnt require this odd redundant "global set global" syntax. It is confusing
to users to have to specify "global" twice.
may I suggest that the syntax for rbd config
one final word of warning for everyone.
while i no longer have the performance glitch
I can no longer reproduce it.
Doing
ceph config set global rbd_cache true
does not seem to reproduce the old behaviour. even if i do things like unmap
and remap the test rbd.
Which is worrying. because

This is attempt #3 to submit this issue to this mailing list. I don't

I have an issue with MDS corruption which so far I haven't been able to
resolve using the recovery steps I've found online. I'm on v15.2.6. I've
tried all the recovery steps mentioned here,
What if you just stop the containers, configure the new IP address for that
server, then restart the containers? I think it should just work as long as
this server can still reach the MONs.

Thanks for this.
Is download.ceph.com more heavily loaded than usual? It's taking more
than 24 hours to rsync this release to our local mirror (and AFAICT
none of the European mirrors have caught up yet).
