Dear Cephers,
On reading a technical blog from Croit:
https://croit.io/blog/ceph-performance-test-and-optimization
It says the following: "It should be noted that it is still debated whether a
configuration with multiple active MDS servers is OK for production Ceph
clusters."
Just wonder whet
Hello all,
I am still digging into this. I disabled this osd from starting at boot, then
rebooted the node.
I then tried doing the following:
sudo cephadm shell
And the following was the result. To me it seems to indicate that the OSD
drive is ok and can be decrypted but does still not run.
Hi Stephen,
I think this output you posted is pretty normal, there is no systemd in the
container, thus the error.
You still need to find the logs. You may try “sudo cephadm logs --name osd.0”.
If that still fails, you should try to run the ceph-osd daemon manually.

Hi,
There is no down OSD:
yeah, I see the same in my lab, it also shows more daemons than I have
for that custom spec. I think it's somehow showing also some failed
attempts to deploy OSDs. In my case it's 4/8 but I only have 8 OSDs in
total, but I changed the spec a couple of times in o
OSD will probably not sart if wal device is lost. You can give a try by
removing the corresponding link to the block device from
/var/lib/ceph/osd/ceph-ID/block.wal. Or it will use block.db for wal in
that case.
IOPS should be counted as well. I would go 1:3 way if we are considering
IOPS. But its
I continued looking into the issue and have no idea what hinders the
performance yet. However:
1. A client operating with kernel 5.3.0-42 (ubuntu 18.04) has no such
problems. I delete a directory with hashed subdirs (00 - ff) and total
space taken by files ~707MB spread across those 256 in 3.25 s
Hi!
While trying to set a domain name for my company's ceph cluster, I used
Nginx on another server to reverse proxy the public IP address of the
dashboard and the port 8443. The domain name is from CloudFlare. The
dashboard came up for HTTP only but threw error for HTTPS and I could not
log in. S
