Situation is --> I have installed openstack setup (Liberty) for my lab. Dear Ceph users,
I need your suggestion for my ceph design. I have Host 1 --> Controller + Compute1 Host 2 --> Compute 2 DELL SAN storage is attached to both hosts as [root@OSKVM1 ~]# iscsiadm -m node 10.35.0.3:3260,1 iqn.2001-05.com.equallogic:0-1cb196-07a83c107-47700000018575af-vol1 10.35.0.8:3260,1 iqn.2001-05.com.equallogic:0-1cb196-07a83c107-47700000018575af-vol1 10.35.0.*:3260,-1 iqn.2001-05.com.equallogic:0-1cb196-20d83c107-7290000002157606-vol2 10.35.0.8:3260,1 iqn.2001-05.com.equallogic:0-1cb196-20d83c107-7290000002157606-vol2 10.35.0.*:3260,-1 iqn.2001-05.com.equallogic:0-1cb196-f0783c107-70a000000245761a-vol3 10.35.0.8:3260,1 iqn.2001-05.com.equallogic:0-1cb196-f0783c107-70a000000245761a-vol3 10.35.0.*:3260,-1 iqn.2001-05.com.equallogic:0-1cb196-fda83c107-927000000275761a-vol4 10.35.0.8:3260,1 iqn.2001-05.com.equallogic:0-1cb196-fda83c107-927000000275761a-vol4 with fdisk -l, it is mentioned as sdc, sdd, sde and sdf on host1 sdb,sdc,sdd,and sde on host 2 I need to configure this SAN storage as CEPH. i am thinking of osd0 with sdc on host1 osd1 with sdd on host1 osd2 with sdd on host2 osd3 with sde on host2 So as to have [root@host1 ~]# ceph osd tree ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY -1 7.95996 root default -2 3.97998 host host1 0 1.98999 osd.0 up 1.00000 1.00000 1 1.98999 osd.1 up 1.00000 1.00000 -3 3.97998 host host2 2 1.98999 osd.2 up 1.00000 1.00000 3 1.98999 osd.3 up 1.00000 1.00000 Is it ok? or i must change my ceph design?
