[SOLVED] PBS with SAN for Backup Storage

[kokel]

Hi there,

we are planning to use SAN for Backup Storage in PBS. Just, because we have a spare SAN Storage to use.
Because of SAN the PBS will see one big Block Device. Any recommendations how to use this big block device, what filesystem should we use?

I have read it is recommended to use a ZFS special device to speed up things. But in case of SAN I assume ZFS would be no good idea.
And in case there isn't ZFS in use for backup storage I think a zfs special device doesn't make any sense, right?

Thanks,
Kokel

As the SAN deals with disk redundancy, you dont have to use ZFS.

You should be able of creating smaller-than-the-whole-SAN LUNs in your SAN and connect to those LUNs from PBS. After that, PBS will see a disk that you may format as ext4 or xfs, mount that partition and use it for a PBS repo.

Thanks for the answers.
@VictorSTS: What do you mean with "creating smaller-than-the-whole-SAN LUNs"?

We plan to use LVM on top of the Block devices presented by SAN.

I understood that "Because of SAN the PBS will see one big Block Device. Any recommendations how to use this big block device" was a problem for you...

So you can use LVM as you plan or simply create LUNs in the SAN a present the space you have in the SAN as a few block devices.

Ahh, ok. The Server is connected directly via Fibre-Channel to the SAN, so we have to create LUNs to present the space to the server.
