OSD per disk.

OSD per disk.

[chandrashekhar]

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.

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

Thanks Alexandre,  I created four directories in /data  (osd0,osd1,osd2,osd3) 
and mounted as below:

/dev/sdb1 -> /data/osd1
/dev/sdc1 -> /data/osd2
/dev/sdd1 -> /data/osd3


But when I start ceph its starting mons and md daemons but not osds. Please help
me to get this working.

Re: OSD per disk.

[Alexandre DERUMIER]

maybe try 

[osd.0] 
host = testnode 
osd data = /data/osd0 
osd journal = /data/osd0/osd0journal 
osd journal size = 1000 

[osd.1] 
host = testnode 
osd data = /data/osd1 
osd journal = /data/osd1/osd1journal 
osd journal size = 1000 
[osd.2] 
host = testnode 
osd data = /data/osd2 
osd journal = /data/osd2/osd2journal 
osd journal size = 1000 
[osd.3] 
host = testnode 
osd data = /data/osd3 
osd journal = /data/osd3/osd3journal 
osd journal size = 1000 



you can start osd with

/etc/init.d/ceph start osd0
/etc/init.d/ceph start osd1
/etc/init.d/ceph start osd2
/etc/init.d/ceph start osd3

You almost certainly do not want to have 2 MON nodes in your cluster; an
odd number of nodes is strongly recommended.

(Reason: a strict majority of MON odes must be up and functional to
maintain quorum; increasing the number of MONs from 1 to 2 makes
failures more likely but does not increase resiliency.)

David

That shouldn't be needed. osd.0 will happily read the [osd] section in
the config file.

How did you create the cluster? mkcephfs?

Do you see log entries in /var/log/ceph/*osd*.log ? What do they say?

Re: OSD per disk.

[Sam Just]

That bug was fixed in f859f25d7eaec01fb6a82b88409d005c8177fea2.

It actually appears to mean that the osd failed to authenticate.

mkcephfs -a -c /etc/ceph/ceph.conf  -k /etc/ceph/keyring.admin -- is working
fine, but when I tried to start ceph its showing following error.
