Hi.
From our point of view, it's important to keep disk failure prediction
tool as part of Ceph, ideally as an MGR module. In environments with
hundreds or thousands of disks, it's crucial to know whether, for
example, a significant number of them are likely to fail within a month

There are no user processes running on them. It only has the operating system and ceph installed.

Hey Rafael,
So these client mounts probably use the kernel mounts with an older kernel
version that gets identified as the luminous client.
You can try upgrading the kernel version and remounting.

Hi Linas,
Is the intent of purging of this data mainly due to just cost concerns? If
the goal is purely preservation of data, the likely cheapest and least
maintenance intensive way of doing this is a large scale tape archive.
Such archives (purely based on a google search) exist at LLNL and OU,
The intent is the US administration’s assault against science, Linas doesn’t
*want* to do it, he wants to preserve for the hope of a better future.

Some of your messages come across without newlines which makes them hard to

Is Block alignment for Databases a thing with RBD?
I heard something with 16K alignment ...
If yes how can be checked what alignment a RBD got.

Hi all,
This most likely boils down to the kernel version of connected clients. We
faced the same problem some time ago and just kicked away the client mds
connections with a follow up kernel update on the servers doing the mount.
I can check the version details later for more clarity.
Best,
Lai
If you have a line on the data, I have connections that can store it or I
can consult pro bono on building a system to store it.
However wan-ceph is not the answer here.

I’ve done the same as well.
It doesn’t help that smartctl doesn’t even try to have consistent output for
SATA, SAS, and NVMe drives, and especially that it doesn’t enforce uniform
attribute labels. Yes, the fundamental problem is that SMART is mechanism

You could interrupt the cleanup task and use the file system.

One of the advantages is that you usually see immediately what is

Can someone paste in here their copy of logrotate?
The trick always with rotating logs is that the service writing to it needs
to be restarted or told to stop writing so the file handle gets closed.
Otherwise it stays open and the free disc space isn't recovered.

It's the same across all versions I have used so far.
