First of all, thank you for your detailed answer.

Good to know.
I shall give that a spin on one of my test cluster nodes then, once a

consider following values for a pool:

The PG calculator generates number of PGs for this pool as : 32768.

Is there an enumerated list of issues with snapshots on cache pools.
We currently have snapshots on a cache tier and haven't seen any
issues (development cluster). I just want to know what we should be
looking for.

I'm not sure why crushtool --test --simulate doesn't match what the
cluster actually does, but the cluster seems to be executing the rules
even though crushtool doesn't. Just kind of stinks that you have to
test the rules on actual data.
Should I create a ticket for this?

This was excellent advice. It should be on some official Ceph
troubleshooting page. It takes a while for the monitors to deal with new
info, but it works.
Thanks again!

Hi Experts,
After implemented Ceph initially with 3 OSDs, now I am facing an issue:
It reports healthy but sometimes(or often) fails to access the pools.
While sometimes it comes back to normal automatically.
For example:
*[*ceph@gcloudcon ceph-cluster]$ *rados -p volumes ls*
No, 262144 ops total in 18 seconds.
Oh ok ;)
rbd bench-write is clearly doing something VERY differently from rados
bench (and given its output was also written by somebody else), maybe some
Ceph dev can enlighten us?
Maybe rbd_cache is merging 4k block to 4M rados objects ?

Hi,
Yeah, my problem is the performance with o_direct and o_dsync.
I guess you switched something at the rbd bench-write results:
elapsed: 18 ops: 262144 ops/sec: 14466.30 bytes/sec: 59253946.11
Means
elapsed: 18
ops: 262144
ops/sec: 14466.30
bytes/sec: 59253946.11
what makes ~4k per IO
26 matches
