Hi Bruce,
RHEL7.0 kernel has many issues on filesystem sub modules and most of them fixed
only in RHEL7.1.
So you should consider to go to RHEL7.1 directly and upgrade to at least kernel
3.10.0-229.1.2

Is there anyone having experience to try to tune Kernel RBD device by changing
scheduler and other settings?
Currently we are trying it on RHEL 7.1 bundled rbd module, to change the
following setting under /sys/block/rbdX/queue:

Dear cepher,
Currently I am working on crushmap to try to make sure the at least one copy
are going to different chassis.
Say chassis1 has host1,host2,host3, and chassis2 has host4,host5,host6.
With replication =2, it's not a problem, I can use the following step in rule

Hi David,
How about your pools size min_size setting?
In your cluster, you may need to set all pools min_size=1 before shutdown server

Hello community,
We have a cluster using v0.80.5, and recently
to BUG#8629, but before upgrade to the patched version, is
there any workaround other than reformat disk and create OSDs?
Also a side question: I don't find this bug fix in release note of v0.80.6 or
v0.80.7, so should I assume the patch is not yet released?
Thanks

Hi all,
I have some questions about unfound objects in rbd pool, what's the real impact

Currently our cluster (running on v0.80.5) has 25 unfound objects due to recent
OSD crashes, and cannot mark as lost yet (Bug #10405 created for this).
So far it seems we can still mount
