It's changed UI because we're hosting them on readthedocs.com now. See

Hello All,
I am looking to understand some of the internal details on how multisite is
architected. On the Ceph user list, I see mentions of metadata logs, bucket
index shard logs etc. but there is just no documentation anywhere I could
find on how multisite works using these.
Could someone pleas
Hmm, so maybe your hardware is good enough that cache is actually not helping?
This is not unheard of. I don't really see any improvement from caching to
begin with. On the other hand, a synthetic benchmark is not really a test that
utilises the good sides of cache (in particular, write merges w

Unfortunately, I was never able to resolve it; the bucket(s) in question had to
be recreated and then removed.

Do you have test results for the same test without caching?
I have seen periodic stalls in any RBD IOP/s benchmark on ceph. The benchmarks
create IO requests much faster than OSDs can handle them. At some point all
queues run full and you start seeing slow ops on OSDs.
I would also prefer if IO

We will be having a Ceph science/research/big cluster call on Wednesday
November 25th. If anyone wants to discuss something specific they can
add it to the pad linked below. If you have questions or comments you
can contact me.
This is an informal open call of community members most

Hi,
I am using the Ceph development cluster through vstart.sh script. I would
like to measure/benchmark read and write performance (benchmark ceph at a
low level). For that I want to use the fio tool.
Can we use fio on the development cluster? AFAIK, we can. I have seen
the fio option in the

We're testing the rbd cache setting for openstack(Ceph 14.2.5 Bluestore

Thomas,
This is config controled by mds's mds_cap_revoke_eviction_timeout(300s
by default). If the client crashed or hung for long time, the cluster
will evict the client.
It can prevent others hung(waiting for locks). If you're the client will
recover later, you can set it zero.
Hoping this he
