Thank you for your reply.

I’m still hoping to get some more input, but there are many people running ceph
on ext4, and it sounds like it works pretty good out of the box. Maybe I’m
overthinking this, then?

I don't think there were any stale or unclean PGs, (when there are,
I have seen "health detail" list them and it did not in this case).
I have since restarted the 2 osds and the health went immediately to HEALTH_OK.

Instead of guessing I took a look at one of my OSDs.
TL;DR: I’m going to bump the inode size to 512 which should fit majority of
xattrs, no need to touch filestore parameters.
Short news first - I can’t find a file with more than 2 xattrs. (and that’s
good)
Then I extracted all the xattrs on a

This reminds me of when a buggy leveldb package slipped into the ceph

Which version of leveldb do you have installed?

Hi,
I've observed the same thing but never spent time to figure that out. It would
be nice to know. I don't think it's a bug, just something slightly confusing.
Cheers

I'll consider looking into more detail at the slow OSDs.

In my experience I have seen something like this this happen twice - First
time there were unclean PGs because Ceph was down to one replica of a PG.
When that happens Ceph blocks IO to remaining replicas when the number
falls below the Œmin_size¹ parameter. That will manifest as blocked ops.

Does anyone know if it is possible to use Ceph storage in Redhat Enterprise
Virtualization (RHEV),
and connect it as a data domain in the Redhat Enterprise Virtualization Manager
(RHEVM).
My RHEV version and Hypervisors are the latest RHEV 6.5 version.

RHEV does not formally support Ceph yet. Future versions are looking to
include Cinder support which will allow you to hook in Ceph.
You should contact your RHEV contacts who can give an indication of the
timeline for this.

Do you recommend to enable or disable hyper threading on CPU ?
Is it the case for Mon ? Osd ? Radosgw ?

I was getting better performance with HT enabled (Intel cpu) for ceph-osd. I
guess for mon it doesn't matter, but, for RadosGW I didn't measure the
difference...We are running our benchmark with HT enabled for all components
though.

Hi Florent,
10x degradation is definitely unusual! A couple of things to look at:
Are 8K rados bench writes to the rgw.buckets pool slow? You can with
something like:
rados -p rgw.buckets bench 30 write -t 256 -b 8192
You may also want to try targeting a specific RGW server to make sure

I change the "mds_cache_size" to 50 from 10 get rid of the
WARN temporary.
Now dumping the mds daemon shows like this:
"inode_max": 50,
"inodes": 124213,
But i have no idea if the "indoes" rises more than 50 , change the
"mds_cache_size" again?
Thanks.
