Re: OSD per disk.

[Alexandre DERUMIER <aderumier@odiso.com>]

Hi, just defined osds in ceph.conf, they mount each disk in correct mountpoint.

this example : 
1st server :
  /dev/sdb1 -> /data/osd0
  /dev/sdc1 -> /data/osd1
  /dev/sdd1 -> /data/osd2
  ....
same for journal.(you can use differents disk for journal or use another partition on same disk)



ceph.conf
[osd] 

osd data = /data/osd$id 
osd journal = /data/osd$id/journal 
osd journal size = 512 

[osd.0] 
host = ceph-node-1 


[osd.1] 
host = ceph-node-1 


[osd.2] 
host = ceph-node-1 



[osd.3] 
host = ceph-node-2 


[osd.4] 
host = ceph-node-2

Objet: OSD per disk. 

Hi, 

I want to setup a ceph cluster with 4 osds ( one OSD per disk), 2 mons, 1 
mds. Please help me to configure this. 

I have a machine with following hardware: 

4 hard disks ( each 500GB). 

/dev/sda - 500G ( OS ) 
/dev/sdb - 500G 
/dev/sdc - 500G 
/dev/sdd - 500G 


OS: ubuntu 12.O4 server ( 64 bit ) 




Thanks, 
Chandra.
