Hi Team,
I was trying to forcefully lost the unfound objects using the below
commands mentioned in the documentation , it is not working in the latest
release , any prerequisites required for EC pool.
cn1.chn6m1c1ru1c1.cdn ~# *ceph pg 4.1206 mark_unfound_lost revert|delete*
-bash: delete: comman
Hi,
I have a similar issue and would also need some advice how to get rid
of the already deleted files.
Ceph is our OpenStack backend and there was a nova clone without
parent information. Apparently, the base image had been deleted
without a warning or anything although there were existi
EC pools only support deleting unfound objects as there aren't multiple
copies around that could be reverted to.
ceph pg mark_unfound_lost delete

It's a very bad idea to accept data if you can't guarantee that it will be
stored in way that tolerates a disk outage
without data loss. Just don't.
Increase the number of coding chunks to 3 if you want to withstand two
simultaneous disk
failures without impacting availability.

Perhaps the image had associated snapshots? Deleting the object
doesn't delete the associated snapshots so those objects will remain
until the snapshot is removed. However, if you have removed the RBD
header, the snapshot id is now gone.

Hi Grigory,
are these lines the only lines in your log file for OSD 15?
Just for sanity, what are the log levels you have set, if any, in your config
file away from the default? If you set all log levels to 0 like some people do
you may want to simply go back to the default by commenting out th

Didn't mean to hit send on that quite yet, but that's the gist of
everything you need to do. There is nothing special about this for RGW vs
AWS except that AWS can set this permission on a full bucket while in RGW
you need to do this on each object when you upload them.

You talked about "using default settings wherever possible"... Well, Ceph's
default settings everywhere they exist, is to not allow you to write while
you don't have at least 1 more copy that you can lose without data loss.

Hi Gregg, John,
Thanks for the warning. It was definitely conveyed that they are dangerous. I
thought the online part was implied to be a bad idea, but just wanted to verify.
John,
We were mostly operating off of what the mds logs reported. After bringing the
mds back online and active, we mo
My cluster got stuck somehow, and at one point in trying to recycle things to
unstick it, I ended up shutting down everything, then bringing up just the
monitors. At that point, the cluster reported the status below.
With nothing but the monitors running, I don't see how the status can say

Thank you everyone for your replies. However, I feel that at least
part of the discussion deviated from the topic of my original post. As

We recently began our upgrade testing for going from Jewel (10.2.10) to
Luminous (12.2.5) on our clusters. The first part of the upgrade went
pretty smoothly (upgrading the mon nodes, adding the mgr nodes, upgrading
the OSD nodes), however, when we got to the RGWs we started seeing internal
