Hi all :
I have some questions about the durability of ceph. I am trying
to mesure the durability of ceph .I konw it should be related with
host and disk failing probability, failing detection time, when to
trigger the recover and the recovery time . I use it with multiple
replication, say k
Hello,
Some osd's not getting activated after a reboot operation which cause that
particular osd's landing in failed state.
Here you can see mount points were not getting updated to osd-num and
mounted as a incorrect mount point, which caused osd. can't able to
mount/activate the osd's.

Hello guys,
we have currently an issue with our ceph setup based on XFS. Sometimes
some nodes are dying with high load with this calltrace in dmesg:

Hi Tyler,
I wanted to make sure you got a reply to this, but unfortunately I don't
have much to give you. It sounds like you already took a look at the
disk metrics and ceph is probably not waiting on disk IO based on your
description. If you can easily invoke the problem, you could attach g
I came across this a few times. My problem was with journals I set up by
myself. I didn't give them the proper GUID partition type ID so the udev
rules didn't know how to make sure the partition looked correct. What the
udev rules were unable to do was chown the journal block device as
ceph:ceph
Is this on an RGW cluster?
If so, you might be running into the same problem I was seeing with large
bucket sizes:

The solution is to shard your buckets so the bucket index doesn't get too big.

Looks like a kernel bug. However this isn't completely up to date,
4.4.0-79 is available. You'd probably better post this o
What are the cephx permissions of the key you are using to issue repair
commands?

Hello all,
I work in the same team as Tyler here, and I can provide more info here..
The cluster is indeed an RGW cluster, with many small (100 KB) objects
similar to your use case Bryan. But we have the blind bucket set up with
"index_type": 1 for this particular bucket, as we wanted to avoid

Thanks very much for the insights Greg!
My most recent suspicion around the resource consumption is that, with my
current configuration, xen is provisioning rbd-nbd storage for guests,
rather than just using the kernel module like I was last time around. And,
