Hi
I'm about to change some SATA SSD disks to NVME disks and for CEPH I too
would like to know how to assign space. I have 3 1TB SATA OSDs so I'll
split the NVME disks in 3 partitions of equal size, I'm not going to
assign a different WAL partition because, if the docs are right, the WAL

I have been trying cephfs on the latest 12.x release.
Performance under cephfs mounted via kernel seems to be as expected maxing out
the underlying storage / resources using kernel version 4.13.4.
However when it comes to mounting cephfs via ceph-fuse looking at performance

I'm sorry I forgot about your issue. Crazy few weeks.
I checked the log you initially sent to the list, but it only contains
the log from one of the monitors, and it's from the one synchronizing.
This monitor is not stuck however - synchronizing is progressing, albeit
slowly.

I copied the log of the crashing monitor to

Can I somehow get access to the logs of the other monitors, without

I would like to not stop them, as currently we are running with 2/3

I can only speak for some environments, but sometimes, you would want to
make sure that a cluster cannot fill up until you can add more capacity.
Some organizations are unable to purchase new capacity rapidly and making
sure you cannot exceed your current capacity, then you can't run into
problems

Hi Bryan.
I hope that solved it for you.
Another think you can do in situations like this is to set the full_ration
higher so you can work on the problem. Always set it back to a safe value
after the issue is solved.
*ceph pg set_full_ratio 0.98*

Are you using erasure coding? I recently was able to reproduce a bug in

hi all,
we have a ceph 10.2.7 cluster with a 8+3 EC pool.
in that pool, there is a pg in inconsistent state.

however, we are unable to solve our issue.
from the primary osd logs, the reported pg had a missing object.

First a general comment: local RAID will be faster than Ceph for a
single threaded (queue depth=1) io operation test. A single thread Ceph
client will see at best same disk speed for reads and for writes 4-6
times slower than single disk. Not to mention the latency of local disks

You may try playing with the sizes of reads/writes. Another
alternative is to use libcephfs directly to avoid
measuring resource load as outlined earlier will show if the drives are
performing well or not. Also how many osds do you have ?

I updated the ticket with some findings. It appears that osd.93 has that
snapshot object in its missing set that gets sent to osd.78, and then
osd.69 claims to have the object. Can you upload debug logs of those OSDs
that go along with this log? (Or just generate a new set of them together.)

I concur - at the moment we need to manually sum the RBD images to look at how
much we have "provisioned" vs what ceph df shows. in our case we had a rapid
run of provisioning new LUNs but it took a while before usage started to catch
up with what was provisioned as data was migrated in. Cep
