Hello all,
bad news the problem shown again today !
I had mounted a bindfs and nfs server running on the same "proxy" server
when I ran a massive chmod on a directory with large amount of data I
got part of the directories that disapeared!
The problem wasn t showing as fast as it was with kernel 3.11 but
it still was showing.
I don t know the origine and if the bindfs / nfs are related.

Hello Yan,
Good guess ! thank you for your advice I updated this morning my
cephfs-proxy ubuntu 13.10 to recommended 3.12 kernel and
after the first preliminary tests the issue isn t showing anymore.

Hello all!
I experience a strange issue since last update to ubuntu 13.10
(saucy) and ceph emperor 0.72.1
kernel version 3.11.0-13-generic #20-Ubuntu
ceph packages installed are the ones for RARING
when I mount my ceph cluster using cephfs and I upload a tons of
data or do a directory listing (find . -printf "%d %k" ) or do
a chown -R user:user * at some point the filesystem disapear!
I don t know how to solve this issue there is no entry in anylog
the only thing that seems to be affected is ceph-watch-notice that
get stuckl
and forbid the unmount "have to pid kill .-9 that process to
umount / mount the ceph cluster on client proxy to start over the
process.
in the chown if I put --changes to slow it down just enought then
the problem seems to disapear.
sounds like the d_prune_aliases() bug. please try updating 3.12 kernel
or using ceph-fuse
Yan, Zheng
Any suggestions are welcome
Atte,
