Hi Alexandre,
What is the behavior of mongo when a shard is unavailable for some reason
(crash or network partition) ? If shard3 is on the wrong side of a network
partition and uses RBD, it will hang. Is it something that mongo will
gracefully handle ?
I have no experience in this but I'm cur

This was this tracker:

But It has been solved and backported to firefly.
Also, can you test 0.80.6 and 0.80.7 ?

Hello!
If I using cache tier 1 pool in writeback mode, it is a good idea turn
off journal on OSDs?
I think in this sutuation journal can help if you are hit a rebalance
procedure in a "cold" storage. In outer situation the journal is
useless, I think.
Any comments?

Hi,
Do you have also tested 0.80.6 and 0.80.7 librbd ?
could be usefull to search commits in git.

Having a few problems removing cephfs file systems.

Hi all,
I'm running a small Ceph cluster with 4 OSD nodes, which serves as a
storage backend for a set of KVM virtual machines. The VMs use RBD for disk
storage. On the VM side I'm using virtio-scsi instead of virtio-blk in
order to gain DISCARD support.
Each OSD node is running on a separate mac

Hello!
I try to collect some info about Ceph performance on cluster. The question
is, if I can collect all metrics from the cluster, or the only way to do it
is to ask all nodes by ceph perf dump commands?
Or, may be, there are some better ways to understand on what operations
Ceph spend time?
And

Hi Howard,
be default each OSD is weighed based on its capacity automatically. So the
smaller OSDs will receive less data than the bigger ones.
Be careful though in this case to properly monitor the utilization rate of all
OSDs in your cluster so that one of them does not reach the odd_full rat

This is very strange, you shouldn't have corruption.
Do you use writeback ? if yes, do you have disable barrier on your filesystem ?

What version of Ceph are you running? It's varied by a bit.
But I think you want to just turn off the MDS and run the "fail"
command — deactivate is actually the command for removing a logical
MDS from the cluster, and you can't do that for a lone MDS because

Hi all,
Trying to do this:

Getting this error:
Error EINVAL: entity client.radosgw.gateway exists but key does not match
What can this be??
Thanks!

My particular interest is for a less dynamic environment, so manual
key distribution is not a problem. Re. OpenStack, it's probably good
enough to have the Cinder host creating them as needed (presumably
stored in its DB) and just send the secret keys over the message bus
to compute hosts as needed

thanks very much for your advice .
yes，as you said，disabled the rbd_cache will improve the read request，but if
i disabled rbd_cache， the randwrite request will be worse. so this method
maybe can not solve my problem, is it ?
In addition , I also test the 0.80.6 and 0.80.7 librbd,they are as good
Wow, Cong
