So, I installed proxmox on my server which used to run OMV bare metal. Now I installed OMV as VM. I used to have some data drive connected to OMV when it was bare metal. How do I connect them directly to OMV VM without loosing any data? All disk shows up under node>>Disks but not under datacenter>> storage. It doesn't even show up in OMV Disks either.
 
You can try this guide from the wiki.

without loosing any data?
Backups would be good.

All disk shows up under node>>Disks but not under datacenter>> storage
This is normal if you just connect the disk to the host. You can, for example, create an EXT4 file system on a disk and mount it to the PVE host without adding it as "storage" to Proxmox VE. To add it to ProxmoxVE you would have to go to Datacenter->Storage->Add Directory and point it ("Directory" in the creation dialog) to the mount path.
 
I was going to try that but I didn't wanted to loose data. you are right, I should have back up but still in process of buying more hard drives. Little spending at time.
 
so I used same command for all of my three disk I want to passthrough for OMV, i think it is only mounting last one and removing other as I as new one. Any idea how to passthrough all three?

Code:
root@mystic:~# qm set 101 -scsi2 /dev/disk/by-id/ata-ST4000VN008-2DR166_ZGY75F6G
update VM 101: -scsi2 /dev/disk/by-id/ata-ST4000VN008-2DR166_ZGY75F6G
Use of uninitialized value $data in split at /usr/share/perl5/PVE/JSONSchema.pm line 792.
root@mystic:~# grep ZGY75F6G  /etc/pve/qemu-server/101.conf
scsi2: /dev/disk/by-id/ata-ST4000VN008-2DR166_ZGY75F6G,size=3907018584K
root@mystic:~# qm set 101 -scsi2 /dev/disk/by-id/ata-ST2000DM001-1ER164_Z4Z2G2XD
update VM 101: -scsi2 /dev/disk/by-id/ata-ST2000DM001-1ER164_Z4Z2G2XD
Use of uninitialized value $data in split at /usr/share/perl5/PVE/JSONSchema.pm line 792.
root@mystic:~# grep Z4Z2G2XD /etc/pve/qemu-server/101.conf
scsi2: /dev/disk/by-id/ata-ST2000DM001-1ER164_Z4Z2G2XD,size=1953514584K
 
Like in the real world, you have to attach your disks to different (virtual) ports if you want to use them in parallel. For example:
Code:
qm set 101 -scsi2 ...
qm set 101 -scsi3 ...
qm set 101 -scsi4 ...
 
Aa, make sense. I tried with out -scsi2 word altogether as noob because i saw that it assign that in somewhere. Is there a limit on how many I can use, not that I am planning to use more than 5 or 10 ever but for knowledge.
 
The qm command lets you assign up to 30 scsi devices. You can search the qm man page for --scsi[n] :)
