never created or some stripe was just simply lost?

Hi,
I've stumpled upon this a couple of times, where Ceph just stops
responding, but still works.
The cause has been package loss on the network layer, but Ceph doesn't
say anything.
Is there a debug flag for showing retransmission of package, or someway
to see that packages are lost?

Hi,
Following-up this issue, I've identified that almost all unfound objects
belongs to a single RBD volume (with the help of the script below).
Now what's the best way to try to recover the filesystem stored on this
RBD volume?

Hello Team,
I have configured ceph as a multibackend for openstack.
I have created 2 pools .

2. poolb (replication size =2 )

What are your ulimit settings? You could be hitting the max process count.

Hi all,
Today I have a problem using CephFS. I use firefly last release, with
kernel 3.16 client (Debian experimental).
I have a directory in CephFS, associated to a pool pool2 (with
set_layout).
All is working fine, I can add and remove files, objects are stored in
the right pool.

Another thing we're looking into is compression. The intersection of
compression and object striping (fracturing) is interesting. Is the striping

That's not how ulimit works. Check the `ulimit -a` output.

Indeed.
And to forestall the next questions, see man initscript, mine looks like
this:

Subject: Re: [ceph-users] Cephfs
Ceph messages are transmitted using tcp, so the system isn't directly aware
of packet loss at any level. I suppose we could try and export messenger
reconnect counts via the admin socket, but that'd be a very noisy measure
-- it seems simplest to just query the OS or hardware directly?

We were building a test cluster here, and I enabled MDS in order to use
ceph-fuse to fill the cluster with data. It seems the metadata server is

You can turn off the MDS and create a new FS in new pools. The ability

Looking at the docs (as below), it seems like .95 and .85 are the default

stop reading an writing to avoid data corruption.

Hi Erick,
the address to use in the mount syntax is the address of your MON node, not the
one of the MDS node.
Or may be you have deployed both a MON and an MDS on ceph01?
