Hi,
I recommend to setup a test environment (VM could be ok, with several
virtual disks to test the zfs, for example 10-12 vms + os disk).
In short:
- install pve as usual
- follow the documents here, it is updated to the latest version:
http://pthree.org/2012/04/17/install-zfs-on-debian-gnulinux/
- read this carefully, it will save your time and frustration:
http://pthree.org/2013/01/03/zfs-administration-part-xvii-best-practices-and-caveats/
Please note:
- zfsonlinux is really great, and relatively easy to manage. Easy as
a pilot can manage a boing 747. In other words, you should play around
zfs before deploy in real life environment.
- do not use hw. raid cards (especially in raidXY mode), just cause
troubles and could be more expensive
- using ZIL is great, safe to use mirror and not more than 4-8GB
- L2ARC is great, safe to use stripped volumes on several disks
(partitions)
- your setup really depends on your real life workload and use case,
hard to tell what is the ultimate best solution, which perfects for
everybody
- and a lot more things, you will see. It has a learning curve and
the benefits are awesome.
Personally I had serious issues with drbd and live migration on
software raid, strange and unexplained (by intel professional)
hardware raid hot swap issue which cause massive data loss and
downtime on the system. Even hours to fsck and data corruption
happened. Now I use zfs nearly 10 months on several systems based on
pve and I have to tell you, awesome.
Bye,
István
many thanks...
just a simple question:
ZFS is a local filesystem
what type of export do you prefer when you share it?
NFSv3 or NFSv4?
O have you other hints?
