I think the client should reconnect when it's out of sleep. Could you

I think you can do the following.
NOTE: If you know the objects that are recently created, you can skip to
step 5
1. List the objects in the metadata pool and copy it to a file
rados -p ls > /tmp/metadata_obj_list
2. Prepare a bulk stat script for each object. Unfortunately xargs didn't

Yes, this issue is already fixed in main [1] and the quincy backport is

Hi,
~6K log segments to be trimmed, that's huge.
1. Are there any custom configs configured on this setup ?
2. Is subtree pinning enabled ?
3. Are there any warnings w.r.t rados slowness ?
4. Please share the mds perf dump to check for latencies and other stuff.

The MDS requests the clients to release caps to trim caches when there is
cache pressure or it
might proactively request the client to release caps in some cases. But the
client is failing to release the
caps soon enough in your case.
Few questions:
1. Have you tuned MDS cache configurations? If
Hi Mathias,
I am glad that you could find it's a client related issue and figured a way
around it.
I too could reproduce the issue locally i.e. when a client which was
initially copying the snapshot still
has access to it even when it's got deleted from the other client. I think
this needs further
Created a tracker to investigate this further.

Hi Thomas,
As the documentation says, the MDS enters up:resolve from up:replay if the
Ceph file system has multiple ranks (including this one), i.e. it’s not a
single active MDS cluster.
The MDS is resolving any uncommitted inter-MDS operations. All ranks in the
file system must be in this state o

Hi Thomas,
I have created the tracker https://tracker.ceph.com/issues/58489 to track

Hi,
First of all I would suggest upgrading your cluster on one of the supported
releases.
I think full recovery is recommended to get back the mds.
1. Stop the mdses and all the clients.
2. Fail the fs.
a. ceph fs fail
3. Backup the journal: (If the below command fails, make rados level c

I think there is no specific recommendation for active-active MDS. Though
2*1G is sufficient,
it is recommended to use 2

Is this the kernel client ? If so, could you try dropping the cache as
below ?
# sync; echo 3 > /proc/sys/vm/drop_caches
Mimic is EOL a long time back. Please upgrade to the latest supported version.
