Hi,
1) I have flavors like 1 vCPU, 2GB memory, 20GB root disk. No swap + no
ephemeral disk. Then I just create an instance via horizon choosing an image +
a flavor.
2) OpenStack itselfs runs on Ubuntu 12.04.4 LTS, for the instances I have some
Ubuntu 12.04/14.04s, Debians and CentOS'.

Hi,
In the last few days I've had some issues with the radosgw in which all
requests would just stop being served.
After some investigation I would go for a single slow OSD. I just restarted
that OSD and everything would just go back to work. Every single time there

Hi,
I did a test with 'rados -p ecdata bench 10 write' on an ECpool
with a cache replicated pool over it (ceph 0.83).
The benchmark wrote about 12TB of data. After the 10 seconds run,
rados started to delete his benchmark files.
But only about 2,5TB got deleted, then rados returned.

Hi Wido,
as the backing disk is running a deep scrub it's constantly 100% busy, no
errors though...
I'm running everything on XFS.
I had a similar feeling that was the OSD slowing down those requests. What
would be the affected pool? .rgw?
thanks,

I am confuse to understand how File store in Ceph.
I do two test. where is the File or the object for the File
①rados put Python.msi Python.msi -p data
②rbd -p testpool create fio_test --size 2048
rados command of ① means use Ceph as Object storage ?
rbd command of ② means use Ceph as Block
Thanks for your reply.
