Hi,
I have a ceph 12.2.8 cluster on filestore with rather large omap dirs
(avg size is about 150G). Recently slow requests became a problem, so
after some digging I decided to convert omap from leveldb to rocksdb.
Conversion went fine and slow requests rate went down to acceptable
level. Unfo
Hey,
After rebooting a server that hosts the MGR Dashboard I am now unable to
get the dashboard module to run.
Upon restarting the mgr service I see the following :

Hello,
I’m trying to find a way to use async+dpdk as network on cep13.2.0. .After I
have compiled ceph with dpdk and mount hugepage, I got a segmentation fault
like this:
./bin/ceph-mon -i a -c ceph.conf
EAL:Detected 48 lcore(s)
EAL: No free hugepages reported in hugepages-1048576KB

Hi Jody,
yes, this is a known issue.
Indeed, currently 'ceph df detail' reports raw space usage in GLOBAL
section and 'logical' in the POOLS one. While logical one has some flaws.
There is a pending PR targeted to Nautilus to fix that:

You can get all the details from the admin socket of the OSDs:
ceph daemon osd.X perf dump
(must be run on the server the OSD is running on)
Examples of relevant metrics are: bluestore_allocated/stored and the
bluefs block for metadata.
Running perf schema might contain some details on the meani
Hello,
I’m trying to find a way to determine real/physical/raw storage capacity usage
when storing a similar set of objects in different pools, for example a 3-way
replicated pool vs. a 4+2 erasure coded pool, and in particular how this ratio
changes from small (where Bluestore block size matt
Hi Florian,
You assumed correctly, the "test" container (private) was created with the
"openstack container create test", then I am using the S3 API to
enable/disable object versioning on it.
I use the following Python snippet to enable/disable S3 bucket versioning:
import boto, boto.s3, boto.s3.

This stuff is logged under the 'civetweb' subsystem, so can be turned
off with 'debug_civetweb = 0'. You can configure 'debug_rgw' separately.

There’s a couple of things I would look into:
* Any packet loss whatsoever – especially on your cluster / private
replication network
* Test against an R3 pool to see if EC on RBD with overwrites is the culprit
* Check to see what processes are in the “R” state during high iowait time
