Hello,
We have cephfs with two active MDS. Currently rank 1 is repeatedly crashing
with FAILED ceph_assert(p->first <= start) in md_log_replay thread. Is there
any way to work around this and get to accesible file system or should we start
with disaster recovery?
It seems similar to

Error EINVAL: hostname is online, please remove host without --offline.
This is strange, why is it online? I thought you couldn't get it to
boot according to your first message. What is the current output of
'ceph orch host ls' and is it still present? Have you failed over the

I know that only a few are using this script but just trying my luck here
if someone has the same issue as mine.
But first, who has successfully used this script and what version did you
use? Im using this guide on my test environment (
Looking at the history I first tried
ceph orch host rm hostname --offline --force
and then
ceph orch host rm hostname --force
The second command must have removed the host (partially) because I
didn't try any other commands after that.
Now when I try these commands again, offline gives
Hi,
we're facing an issue during upgrades (and sometimes server reboots),
it appears to occur when (at leat) one of the MONs has to do a full
sync. And I'm wondering if the upgrade procedure could be improved in
that regard, I'll come back to that later. First, I'll try to
summarize the
I still saw client cache pressure messages, although I think it did in
general help a bit. What I additionally just did (like 5 minutes ago),
was reduce "mds_recall_max_caps" from 30,000 to 10,000 after looking at

As Dietmar said, VS Code may cause this. Quite funny to read,
actually, because we've been dealing with this issue for over a year,
and yesterday was the very first time Ceph complained about a client

Hi - in my home , I have been running cephfs for a few years, and have
reasonably good performance, however since exposing cephfs via SMB has been hit

Hi,
I'm not the biggest rbd-mirror expert.
As understand it, if you use one-way mirroring you can failover to the
remote site, continue to work there but there's no failover back to
primary site. You would need to stop client IO on DR, demote the image
and then import the remote images
Hi, did you remove the host from the host list [0]?

Hi all,
In my small cluster of 6 hosts I had troubles with a host (osd:s) and
was planning to remove it from the cluster. Before I got to do that I
needed to power down this host and therefore put it in maintenance mode.
Due to some mistakes on my part I couldn't boot the host again and
Hi,
it's a bit much output to scan through, I'd recommend to omit all
unnecessary information before pasting. Anyway, this sticks out:
