Hi,
root@ppm-c240-ceph3:/var/run/ceph# ceph --admin-daemon
/var/run/ceph/ceph-osd.11.asok config show | less | grep rgw_max_chunk_size
"rgw_max_chunk_size": "524288",
root@ppm-c240-ceph3:/var/run/ceph#
And the value is above 4 MB.

Thanks Craig.
I will try that!
I thought it was more complicate than that because of the entries for
the "public_network" and "rgw dns name" in the config file...
I will give it a try.

I have a 3 node Ceph 0.87 cluster. After a while I see an error in radosgw
and I don’t find references in the list archives
heartbeat_map is_healthy 'RGWProcess::m_tp thread 0x7fc4eac2d700' had timed

The only solution is restart radosgw and for a while it works just fine
Any idea
Hi there,
today I had an osd crash with ceph 0.87/giant which made my hole cluster

Hi Gregory,
Sorry for the delay getting back.
There was no activity at all on those 3 pools. Activity on the fourth
pool was under 1 Mbps of writes.
I think I waited several hours, but I can't recall exactly. One hour at
least is for sure.
Thanks

There are really only two ways to do snapshots that I know of and they have
trade-offs:
COW into the snapshot (like VMware, Ceph, etc):
When a write is committed, the changes are committed to a diff file and the
base file is left untouched. This only has a single write penalty, if you

You may need split horizon DNS. The internal machines' DNS should resolve
to the internal IP, and the external machines' DNS should resolve to the
external IP.
There are various ways to do that. The RadosGW config has an example of

Hi,
The 2147483647 means that CRUSH did not find enough OSD for a given PG. If you
check the crush rule associated with the erasure coded pool, you will most
probably find why.

So the problem started once remapping+backfilling started, and lasted until
