I will have to do some looking into how that is done on Proxmox, but most
definitely.

Any chance you can attempt to repeat the process on the latest master
or pacific branch clients (no need to upgrade the MONs/OSDs)?

The steps are pretty straight forward.
- Create rbd image of 500G on the primary
- Enable rbd-mirror snapshot on the image
- Map the image on the primary
- Format the block device with ext4
- Mount it and write out 200-300G worth of data (I am using rsync with some
local real data we have)
Any chance you could write a small reproducer test script? I can't
repeat what you are seeing and we do have test cases that really
hammer random IO on primary images, create snapshots, rinse-and-repeat
and they haven't turned up anything yet.
Thanks!

I have been doing a lot of testing.
The size of the RBD image doesn't have any effect.
I run into the issue once I actually write data to the rbd. The more data I
write out, the larger the chance of reproducing the issue.
I seem to hit the issue of missing the filesystem all together the

it is possible that the payload reduction also solved or at least reduced a

Hello everyone,
I'm trying to add an OSD node to my current cluster. I created an lvm volume
for this node to use for OSD.
My current Ceph version is 14.2.6 and it runs on an RHEL 7 OS.
However, I got error when trying to activate the node. I'm confused with the
output. I tried to see what
Just to follow up with an anecdote -- I had asked the question because
we had to do a planned failover of one of our MDSs.
The intervention went well and we didn't need to remove the openfiles
table objects.
We stopped the active mds.0 then the standby took over -- the rejoin
step took around 5
