Hi,
Can you try modifying osd_snap_trim_sleep ? The default value is 0, I have good
results with 0.25 with a ceph cluster using SATA disks :
ceph tell osd.* injectargs -- --osd_snap_trim_sleep 0.25
Best regards,

Hi Kris,
Indeed I am seeing some spikes on the latency, they seem to be linked to
other spikes on throughput and cluster global IOPS. I also see some spikes
on the OSD (I guess this is when the journal is flushed) but IO on the
journals are quite steady. I already tuned a bit the osd filestore and

Hi Loic,
I applied the fixed version. I don't get error messages when running

Just try to give the booting OSD and all MONs the resources they ask for (CPU,
memory).
Yes, it causes disruption but only for a select group of clients, and only for
a moment (<20s with my extremely high number of PGs).
From a service provider perspective this might break SLAs, but until you get
Unfortunately I haven't found a newer package for centos in ceph repos.
Not even an src.rpm so I could build the newer package on CentOS.
I've re-created the monitor on that machine from scratch (this is fairly
simple and quick).

When I adjusted the third parameter of OPTION(osd_snap_trim_sleep, OPT_FLOAT,
0) from 0 to 1, the issue could be fixed. I tried again with the value 0.1, it
would not cause any problem either.
So what is the best choice, Have you got a commended value?
Thanks!!

Thanks, I'll look into that.

Hi,
I try to test ceph 9.2 cluster.
My lab have 1 mon and 2 osd with 4 disks each.
Only 1 osd server (with 4 disks) are online.
The disks of second osd don't go up ...

Hi to all
Someone has news about Geo-replication?

If you don't need synchronnous replication then asynchronnous is the way to go,
but Ceph doesn't offer that natively. (not for RBD anyway, not sure how radosgw
could be set up).
200km will add at least 1ms of latency network-wise, 2ms RTT, for TCP it will
be more.
For sync replication (which ce
If using s3cmd to radosgw and using s3cmd's --disable-multipart option, is
there any limit to the size of the object that can be stored thru radosgw?
Also, is there a recommendation for multipart chunk size for radosgw?

Thanks Josh - this turned out to be a snafu on our end, filesystem out of
space, sorry for the hassle.
The workaround completely resolved the merge-diff failure. Thanks again!

Thanks a lot for your help, Varada. Since I was deploying Ceph via ceph-deploy
I could not see the actual errors. Low disk space led to a failure in creating
monfs. Things are now working fine.
