1 Ganet extstorage provider for local zfs volumes
3 http://docs.ganeti.org/ganeti/master/html/man-ganeti-extstorage-interface.html
7 On node which has zfs storage pool
9 cd /usr/share/ganeti/extstorage/
10 git clone https://github.com/ffzg/ganeti-extstorage-zfs zfs
14 You need to specify zfs filesystem under which block devices will be created.
16 Now ssh into ganeti master node and do following:
18 1. enable new disk template
20 gnt-cluster modify --enabled-disk-templates plain,drbd,ext \
21 --ipolicy-disk-templates plain,drbd,ext
23 2. create log directory
25 mkdir /var/log/ganeti/extstorage
27 3. try instance creation with something similar to
29 gnt-instance add -t ext --disk=0:size=10G,provider=zfs \
30 --disk=1:size=20G,provider=zfs \
31 -n arh-hw --no-name-check --no-ip-check \
32 -o debootstrap+default -B maxmem=512M zfs-ext-test
