Hi all,
on my ceph admin machine, a lot of large files are produced by
prometheus, e.g.:
./var/lib/ceph/8c774934-1535-11ec-973e-525400130e4f/prometheus.cephadm/data/wal/00026165
./var/lib/ceph/8c774934-1535-11ec-973e-525400130e4f/prometheus.cephadm/data/wal/00026166

Hi all,
I'm running Pacific with cephadm.
After installation, ceph automatically provisoned 5 ceph monitor nodes across
the cluster. After a few OSDs crashed due to a hardware related issue with the
SAS interface, 3 monitor services are stopped and won't restart again. Is it
related to the OS
. But without any logs or more details
it's just guessing.
Regards,
Eugen

Compare the keyring file with the ones on the working mon nodes.

Hi Eugen,
I assume the mon db is stored on the "OS disk". I could not find any
error related lines in cephad

Hi all,
in Ceph Pacific 6.2.5, the MDS failover function does not working. The

mds remain until now to standby. Also the cluster remains in Ceph Error

Hi all,
while trying to perform an update from Ceph Pacific to the current Patch
version, errors occure due to failed osd deamon which are still present
and installed on some Ceph hosts although I purged the corresponding OSD
using the GUI. I am using a Red Hat environment, what is the save wa
the save way to tell ceph to also delete specific deamon ID
(not OSD IDs)?

Hi,
the strange thing is that on 2 different host, an OSD deamon with the

remove these daemons or what could be the
preferred workaround?

Hi all,
I have a similar question regarding a cluster configuration consisting
of HDDs, SSDs and NVMes. Let's say I would setup a OSD configuration in
a yaml file like this:

placement:
host_pattern:'*'
spec:
data_devices:

Hi all,
for a ceph cluster with RAM size of 256 GB per node, I would increase
the osd_memory_target from default 4GB up to 12GB. Through the ceph
dashboard, different values are given to set the new value (global, mon,
..., osd). Is there any difference between them? From my point of view,

Dear Ceph users,
I have a small Ceph cluster where each host consist of a small amount of
SSDs and a larger number of HDDs. Is there a way to use the SSDs as
performance optimization such as putting OSD Journals to the SSDs and/or
using SSDs for caching?
Best regards,

be a better and more stable
option, although it is unlikely that you will be able to automate this
with Ceph toolset.

i am planning to set up on my ceph cluster an RBD pool for virtual

Are there any performance issues when using both RBD and CephFS or is it
