Just for posterity, we made the CephFS available again.
We walked through the disaster recovery steps where one of the steps
was to reset the journal. I was under the impression that the
specified command 'cephfs-journal-tool [--rank=N] journal reset' would
simply reset all the journals
Good to hear that, Eugen!

Hi,
I'm developing RBD images' backup system. In my case, a backup data
must be stored at least two weeks. To meet this requirement, I'd like
to take backups as follows:
1. Take a full backup by rbd export first.
2. Take a differencial backups everyday.
3. Merge the full backup and the oldest

Hi,
I saw in the changelogs that it should now finally be possible to delete
files from lost+found with 18.x .
I upgraded recently but still I can't delete or move files from there. I
tried to change permissions but still every time I try it, I get "read
only filesystem" but only when
Thanks for this, I've replied above but sadly a client eviction and remount
didn't help.

Hi,
Thank you very much for the reply.
So I evicted all my clients and still no luck. Check for blocked ops returns 0
from each mds service. Each mds service is serving a different pool suffering
the same issue.
If I write any recent files I can both stat and pull those so I have zero
issues
Per Guillaume it was tested and does not have any impact on other areas.
So I will cherry-pick it for the release
Thx

Hi Yuri,
Any chance we can include [1] ? This patch fixes mpath devices deployments, the
PR has missed a merge and was backported onto reef this morning only.

Hi,
I'm trying to help someone with a broken CephFS. We managed to recover
basic ceph functionality but the CephFS is still inaccessible
(currently read-only). We went through the disaster recovery steps but
to no avail. Here's a snippet from the startup logs:
---snip---
mds.0.41
So we did walk through the advanced recovery page but didn't really
succeed. The CephFS is still going to readonly because of the
purge_queue error. Is there any chance to recover from that or should
we try to recover with an empty metadata pool next?
I'd still appreciate any comments. ;-)
Hi Mohamed,
Changing weights is no longer a good practice.
The balancer is supposed to do the job.
The number of pg per osd is really tight on your infrastructure.
Can you display the ceph osd tree command?

Hi,
Another update: after 2 more weeks the mgr process grew to ~1.5 GB, which
again was expected:
mgr.ceph01.vankui ceph01 *:8443,9283 running (2w)102s ago 2y
1519M- 16.2.14 fc0182d6cda5 3451f8c6c07e
mgr.ceph02.shsinf ceph02 *:8443,9283 running (2w)102s ago 7M
After analysis, our cluster used compression, but did not use isal during
compression.
The compilation of ISAL compress in the current code depends on the macro
HAVE_NASM_X64_AVX2. However, the macro HAVE_NASM_X64_AVX2 has been removed,
resulting in the compression not using ISAL even if
Hello the team,
We initially had a cluster of 3 machines with 4 osd on each machine, we
added 4 machines in the cluster (each machine with 4 osd)
We launched the balancing but it never finished, still in progress. But the
big issue: we have an osd full and all the pools on this osd are read only.
Hi Frank,
Sure, just take your time.
Thanks

Hi Xiubo,
I will update the case. I'm afraid this will have to wait a little bit though.
I'm too occupied for a while and also don't have a test cluster that would help
speed things up. I will
