Unable to select drives during installation

During the installation, I was able to select the system disk, but after the reboot and going through the setup (step 7) where you select the 3 boxes "management services, local storage and Iscsi service" there are no disk present, just blank.  A note was under the screen shot saying that you can skip adding disks now and do it later after building the cluster.....  Well all 3 servers were reloaded and all 3 were talking to each other.  Got into the management web  on port 5000 and it all looked good. On the dashboard, there were all "0" for the Osd clusters.  Tried to add a Iscsi disk and it just looks at me.  there is nothing in the disk list.  Can go into the "Node list", all 3 servers are there and if you click on "edit", it shows the disks are there, and up state.  Physical disk show its there but no status, journal .  What did I miss?

in the Node List -> Physical Disks do you see your disks ? do you see a + button to add OSD and +j to add journal   ?

In the Node List- it lists the Name, Type, Management IP, Status and Action, all 3 disks are reporting as a 3.64TB size.  Under Action, Physical Disk List, View Log and Node Role Setting.  Under Physical Disk List its has the disk parameters listed, Used as System but no Status, Journal or Action.  Under Roles, management, Local Storage Service and ISCSI Target Service are check (unable to change settings).  Under Physical Disks, do not see any (+) button.  Using Chrome and IE 11.  Thanks

Are all disks are showing as "System"  in their usage ?

Can you show the output of

ceph-disk list

yes, all disk are showing usage as "system".

root@PS-NODE-1:~# root@PS-NODE-1:~# ceph-disk list
/dev/sda :
/dev/sda1 other, ext4, mounted on /boot
/dev/sda2 other, ext4, mounted on /
/dev/sda3 other, ext4, mounted on /var/lib/ceph
/dev/sda4 other, ext4, mounted on /opt/petasan/config
/dev/sr0 other, unknown

 

I had understood you have 3 disks in each node, but maybe you meant 3 disks in total which seems to be the output of ceph-disk.

In PetaSAN or most storage systems,  the system/os disk is not used for storage, this is for performance reasons since you want storage disks to be dedicated for that purpose. So you need more 1 disks per node so you can have storage disks.

Ok, misunderstood.  I'll split the RAID up on the Nodes so two disk will be seen on each node.  Thanks for the help

Cool, one thing to note in PetaSAN/Ceph : do not use RAID, Ceph does its own redundancy/self healing and prefers to have direct access to disks.
