Hi all,
I deploy ceph 0.56.6,
I have 1 server run OSD deamon (format ext4), 1 server run Mon + MDS.
I use RAID 6 with 44TB capacity, I divided into 2 partitions *(ext4)*, each
corresponding to 1 OSD.
Ceph -s:
health HEALTH_OK
monmap e1: 1 mons at {0=10.160.0.70:6789/0}, election epoch 1, quorum 0 0
osdmap e34: 2 osds: 2 up, 2 in
pgmap v1207: 576 pgs: 576 active+clean; 79200 MB data, 194 GB used,
38569 GB / 40811 GB avail; 60490KB/s wr, 14op/s
mdsmap e18: 1/1/1 up {0=1=up:active}, 1 up:standby
ceph osd tree
# id weight type name up/down reweight
-1 44 root default
-3 44 rack unknownrack
-2 44 host Ceph-store
0 22 osd.0 up 1
1 22 osd.1 up 1
But when I upload the data to mount partition of CEPH, I see errors:

It takes place continuously, without a break.
Kernel 2.6.32-358 did not support sync ?
I need help!
Thanks
