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

Now what's the best way to try to recover the filesystem stored on this

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.
But when C
Hi,
I am running all commands as root, so there are no limits for the processes.

Another thing we're looking into is compression. The intersection of
compression and object striping (fracturing) is interesting. Is the striping
variable on a per-object basis?

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

Hi,
I am new to ceph file system, and have got a newbie question:
For a sparse file, how could ceph file system know the hole in the file was
never created or some stripe was just simply lost?
Thanks,

Indeed.
And to forestall the next questions, see "man initscript", mine looks like
this:
---
ulimit -Hn 131072
ulimit -Sn 65536
# Execute the program.
eval exec "$4"

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
having problems, so I figured I'd just remove it and rebuild it. However, the
"ceph-deploy mds destroy" command is not implemented; it appears that
You can turn off the MDS and create a new FS in new pools. The ability
to shut down a filesystem more completely is coming in Giant.

Hi,
I'm n00b in the ceph world, so here I go. I was following this tutorials
[1][2] (in case you need to know if I missed something), while trying to

(actually following what's there in [2]).
mount error 5 = Input/output error
What does your mount command look like ?

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?
