5+ disk installation

[svennd]

Hey,

Is it possible to have an installation with more then 5 disks ? I have a 8 disk machine. I'm in doubt about zfs-raid10 or zfs-raid6, either way, i want to use all, is it possible if so how ? :$

thx !

kind regards,

Svenn

you want 8 disk in a ZFS RAID10 or zraid? the ISO installer currently does not support this but there is already a feature request for this:

see https://bugzilla.proxmox.com/show_bug.cgi?id=611

I wanted RAIDZ2 or "zfs's raid 10 alternative". Both are oke, so the best way to go at this is installing debian and upgrade to proxmox from there ? or is there a way around in debug installer mode ?

Thanks for the reply Tom!

From my extensive reading lots and lots about ZFS, you probably don't want all 8 disks in the same vdev. If you want to do raid-10, then start by using two disks in a mirror at install time, then you can grow your zfs pool by adding more mirror pairs to it. They'll get striped in and you'll have your RAID-10 equivalent.

My current servers I just built have two SSD's for boot/system, and 4 seagate constellations for data. I used the two SSDs on the initial install and manually created another zfs pool with the other four drives afterwards.

Yes, i think this is the best way! Have it too. It is much more better performance on hdds were is the whole partion in zfs.
