Hi,
We have extended our clusters with some new nodes and currently it is
impossible to remove from any old node the nvme drive which holding the index
pool in the cluster without generating slow ops and cluster performance

Currently how I want to remove is in quincy non cephadm c
BlueStore vs Filestore doesn’t matter beyond each OSD. Filestore is very
deprecated so you’ll want to redeploy any Filestore OSDs when you can. `ceph
osd metadata` can survey.
I’ve had multiple issues over time with the MG spinners fwiw. For what SAS
spinners cost with some effort you ca
Hello folks! I hope you are doing well :)
I have a general question about XFS and LVM backend OSD performance
and possible effects if they are used together in the same pool.
I built a cluster 5 years ago with Nautilus and I used the XFS backend for
OSD's.
After 5 years they reached me back with
My point is that you may have more 10-30s delays that aren’t surfaced.

So far metrics of the hosted VMs show no other I/O slowdown except when these
hiccups occur.

Hi Tim,
there is no log attached to your post, you better share it via some
other means.
BTW - what log did you mean - monitor or OSD one?
It would be nice to have logs for a couple of OSDs suffering from slow
ops, preferably relevant to two different cases.
Thanks,
Igor

All devices are affected equally, every time one or two random ODSs report slow
ops. So I don't think the SSDs are to blame.
Thanks,

Hi,
I just noticed across different Ceph versions that when browsing the
dashboard, the MGR is logging lots of prometheus queries for the
balancer status:
