hi all!
I have 12 nodes ceph clouster ( 1 mon 2mds 9osd). today my osd.0 osd.3 osd.4 are down and can not restart them!
osd.0 , osd.3, osd.4 are in the same host which name is osd0!
firstly, here is the osd log:
#tail -f /var/log/ceph/osd.0.log
ceph version 0.62(***************************) , process ceph-osd, pid 20667
**ERROR:unable to open superblock on /data/osd.0 : (2) No such file or directory
secondly, /data/osd.0 is exit :
#ssh osd0 ls /data
osd.0 osd.3 osd.4
thirdly, I check the format of osd !
#mount
...
/dev/sda3 on /data/osd.0 type btrifs(rw noatime)
/dev/sdb3 on /data/osd.3 type btrifs(rw noatime)
/dev/sdb3 on /data/osd.4 type btrifs(rw noatime)
It seems that all work is ok! but why can not resart the osd in my cluster!
Any pointers would be much appreciated!
thanks!
peng
