Hi ,
Are your OSDs disk file system btrfs ? or ext4 ,ext3 , or ??
i use ceph 0.23 , ubuntu 10.10 x86_64,2.6.35-22 ,mount btrfs osd is
successful, but mount ext4 osd fail, with its logs , it seems that it
should set "osd journal = /PATH/TO/JOURNAL" at ceph.conf and set
"user_xattr" at /etc/fstab. you can try it.
