Hello,
I'm a newbie to CEPH, gaining some familiarity by hosting some virtual
machines on a test cluster. I'm using a virtualisation product called
Proxmox Virtual Environment, which conveniently handles cluster setup,
pool setup, OSD creation etc.
During the attempted removal of an OSD, my pool
will always hit at least 22% of your OSDS, and probably more. If you're
unable to add more disks, I would highly recommend adding SSD journals.

Hi all,
I think I know the answer to this already after reading similar queries,
but I'll ask in case times have changed.
After an error on my part, I have a very small number of pgs in
remapped+peering. They don't look like they'll get out of that state.
Some IO is blocked too, as you
No, I/O will block for those PGs as long as you don't mark them as
lost.
Isn't there any way to get those OSDs back? If you can you can restore
the PGs.
Interesting, 'lost' is a term I'm not yet familiar with, regarding ceph.
I'll read up on it.
One of the OSDs was re-used straight away, and
. In case I should be troubleshooting this side, is/isn't this happening
to others?

You can turn the filestore up to 20 instead of 1. ;) You might also explore

reveals references to log files which have very similar entries,
but I can't see anything that just repeats like mine does.

Hi all,
First off, I should point out that this is a 'small cluster' issue and
may well be due to the stretched resources. If I'm doomed to

After seeing some recommendations I found in another thread, my impatience got
the better of me, and I've start the process again, but there is some logic, I
promise :-)
I've copied the process from Michael Kidd, I believe, and it goes along the
lines of:
setting noup, noin,
perhaps? Is the activity leading up to something, and BTRFS is slowly
doing what Ceph is asking of it, or is it just going round and round in
circles and I just can't see? :-)

That's fair enough Greg, I'll keep upgrading when the opportunity arises, and
maybe it'll spring back to life someday :-)

After messing up some of my data in the past (my own doing, playing with
BTRFS in old kernels), I've been extra cautious and now run a ZFS mirror
across multiple RBD images. It's led me to believe that I have a faulty
SSD in one of my hosts:
