Hi Patrick,
I haven't gone through this thread yet but I want to note for those
reading that we do now have documentation (thanks for the frequent
pokes Janek!) for the recall configurations:
https://docs.ceph.com/en/latest/cephfs/cache-configuration/#mds-recall
Please let us know if it's missi
This sounds like there is one or a few clients acquiring too many
caps. Have you checked this? Are there any messages about the OOM
killer? What config changes for the MDS have you made?
Yes, it's individual clients acquiring too my caps. I first ran the
adjusted recall settings you suggeste
Yes, use everywhere virtio-scsi (via kvm with discard='unmap'). 'lsblk
--discard' also shows discard is supported. vm's with xfs filesystem
seem to behave better.

I should have started out by asking how is the RBD mounted? Directly

What driver did you use to mount the volumes? I believe only
virtio-scsi supports fstrim commands.

Is there a solution for this? Because I have some more old vm's having
x100GB's of free fs.

Thanks for bringing this up.
We need to update Cheroot in Fedora and EPEL 8. I've opened

get this into Fedora first.
I've published an el8 RPM at

Hi,
We have a ceph 15.2.7 deployment using cephadm under podman w/ systemd.

In our case, eventually the mgr container stops emitting output/logging. We

All:
I recently was tasked with building and implementing Ceph in an
environment where FIPS cryptography is strictly enforced. As such, I ran into
several issues regarding Ceph's use of low-level cryptographic functions since
those are strictly forbidden when OpenSSL is in FIPS mode. The
Never mind, when I enable it on a more busy directory, I do see new
ephemeral pins popping up. Just not on the directories I set it on
originally. Let's see how that holds up.

Thanks. I tried playing around a bit with
mds_export_ephemeral_distributed just now, because it's pretty much the
same thing that your script does manually. Unfortunately, it seems to
have no effect.
I pinned all top-level directories to mds.0 and then enabled

Hi，Jason：
As discussed last time，After setting conf_rbd_qos_bps_limit, the speed of
discard is also limited，
which can make operation such as mkfs.xfs very slow, though we can add -K
option to solve this problem,
but we can't make sure that other operation or application never call discard

What exactly do you set to 64k?
We used to set mds_max_caps_per_client to 5, but once we started
using the tuned caps recall config, we reverted that back to the
default 1M without issue.
mds_max_caps_per_client. As I mentioned, some clients hit this limit
regularly and they aren't entir
