Hi Josh,
thank you for your answer, but I was in Bobtail so no listwatchers command :)
I planned a reboot of concerned compute nodes and all went fine then. I updated

hello!
Today our radosgw crashed while running multiple deletions via s3 api.
Is this known bug ?

Hi,
I think about sharding s3 buckets in CEPH cluster, create
bucket-per-XX (256 buckets) or even bucket-per-XXX (4096 buckets)
where XXX is sign from object md5 url.
Could this be the problem? (performance, or some limits)

We, in our environment, need a shared file system for

Is anyone using CephFS for this purpose?
When folks say CephFS is not production ready, is the primary concern

Hi,
RBD has had support for sparse allocation for some time now. However, when
using an RBD volume as a virtual disk for a virtual machine, the RBD volume
will inevitably grow until it reaches its actual nominal size, even if the
filesystem in the guest machine never reaches full utilization.

There is TRIM/discard support and I use it with some success. There are some
details here http://ceph.com/docs/master/rbd/qemu-rbd/ The one caveat I have
is that I've sometimes been able to crash an osd by doing fstrim inside a guest.

For what it's worth, I was still seeing some small sequential write
degradation with kernel RBD with dumpling, though random writes were not
consistently slower in the testing I did. There was also some variation
in performance between 0.61.2 and 0.61.7 likely due to the workaround we

Jumping in pretty late on this thread, but I can confirm much higher CPU
load on ceph-osd using 0.67.1 compared to 0.61.7 under a write-heavy RBD
workload. Under my workload, it seems like it might be 2x-5x higher CPU
load per process.
Thanks,

I've just been looking into this but have not yet tested. It looks like
discard is supported in the newer virtio-scsi devices but not virtio-blk.

Same problem with me. It took me one step further to add the public network
parameter to all the ceph.conf files. However, ceph-deploy tells me mons are
created but those won’t show up in ceph -w output.

Hey Greg,
I encountered a similar problem and we're just in the process of
tracking it down here on the list. Try downgrading your OSD-binaries to
0.61.8 Cuttlefish and re-test. If it's significantly faster on RBD,
you're probably experiencing the same problem I have with Dumpling.

Hey Greg,
Thanks for the tip! I was assuming a clean shutdown of the OSD should
flush the journal for you and have the OSD try to exit with it's
data-store in a clean state? Otherwise, I would first have to stop
updates a that particular OSD, then flush the journal, then stop it?

Hey Greg,
I didn't know that option, but I'm always careful to downgrade and
upgrade the OSDs one by one and wait for the cluster to report healthy
again before proceeding to the next, so, as you said, chances of losing
data should have been minimal. Will flush the journals too next time.
Thanks!
I should have also said that we experienced similar performance on
Cuttlefish. I have run identical benchmarks on both.

Ah. Right. So I should then be looking at:

Thank you - It works now as expected.
I've removed the MDS. As soon as the 2nd osd machine came up, it fixed
