Hi Jeremy,
good to know you managed to bring your OSDs up.
Have you been able to reweight them to 0 and migrate data out of these
"broken" OSDs?
If so I suggest to redeploy them - the corruption is still in the DB and
it might pop-up one day.
If not please do that first - you might still h
I have a vm on a osd node (which can reach host and other nodes via the

I can live-migrate the vm in this locked up state to a different host

I am not really familiar with spark, but I see it often used in
combination with mesos. They currently implemented a csi solution that
should enable access to ceph. I have been trying to get this to work[1]

Is there not some genius out there that can shed a ligth on this? ;)
Currently I am not able to reproduce this. Thus it would be nice to have
some procedure at hand that resolves stale cephfs mounts nicely.

Ceph RGW is frequently used as a backing store for Hadoop and Spark
(S3A connector).

Hi,
there have been several threads about hanging cephfs mounts, one quite
long thread [1] describes a couple of debugging options but also
mentions to avoid mounting cephfs on OSD nodes in a production
environment.
Do you see blacklisted clients with 'ceph osd blacklist ls'? If the

Hi Istvan,
I'm not sure it helps, but here's at least some pitfalls we faced when
migrating radosgws between clusters.

Hi Joachim
Thanks for that pointer. I've pulled ceph-iscsi from there and and
trying to get things going now on buster.
The problem I have at the moment though is with python3-rtslib-fb. That
hasn't been backported to buster, and the latest in the main buster repo
is 2.1.66, but ceph-iscsi r

Hi Igor,
I had taken the OSDs out already, so bringing them up allowed a full
rebalance to occur.
I verified that they were not exhibiting ATA or SMART-reportable errors,
wiped them and re-added.
I will deep scrub.
Thanks again!

I'm going to resurrect this thread in hopes that in the 6 months since, someone

Thanks David! A couple of things have happened since the last update.
The primary Fedora cheroot package maintainer updated cheroot from
