How to install ZFS-fuse under Proxmox

(Tested with Kernel 2.6.32)

 apt-get install build-essential libaio-dev libattr1-dev libacl1-dev libz-dev libz-dev libfuse-dev libfuse2 scons libssl-dev
 wget -nd http://zfs-fuse.net/releases/0.6.0/zfs-fuse-0.6.0.tar.bz2
 tar jxvf zfs-fuse-0.6.0.tar.bz2
 cd zfs-fuse-0.6.0
 cd src
 scons
 scond install

Fire up ZFS-fuse daemon

 /usr/local/sbin/zfs-fuse

Create Zpool

 zpool create -m /var/lib/vz/images2 /dev/sdb

Create ZFS

 zfs create images2/109

ZFS clone a vm 109 to vm 110

 zfs snapshot images2/109@master
 zfs clone images2/109@master images2/110

Debian GNU/kFreeBSD

zfs works much better using Debian/GNU kFreeBSD then fuse.

after installing the system to kvm or hardware:

• add some disks . in KVM i was only able to get ide to work.

• the scsi disks look like:

ls /dev/ad*
/dev/ad10  /dev/ad10s1  /dev/ad10s2  /dev/ad11  /dev/ad12  /dev/ad13

• per http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide - if I read it right - use entire disk not slices for zfs (I assume slices = partitions).

• if the disks have partition tables, then clear them. just not the operating system disk! I used fdisk to clear the tables. This may not be necessary , if it is not then please delete this part.

fdisk /dev/ad11
o
w

then same for ad12 and ad13

• install this

aptitude install zfsutils

• make a pool

zpool create -f  zfs-pool /dev/ad11 /dev/ad12  /dev/ad13

df | grep zfs-pool
zfs-pool       zfs    1.4T   18K  1.4T   1% /zfs-pool
