17 1-enable-ext-template.sh 2-create-log-directory.sh 3-lvm-wrappers.sh
19 Cron helper can be install under /etc/cron.daily
22 daily-block-snapshot purge-log
24 Overview commands are available (try running them to see output):
27 ill list node size snap
29 Create test instances:
32 t/drbd.sh t/plain.sh t/zfs.sh
34 Review that instaces have been created:
38 Test ganeti commands after reading them:
41 t/gnt-backup-export.sh t/gnt-instance-modify.sh
46 Ganti's extstorage provider doesn't support drbd target. But, lvm emulation scripts are sufficiant enough

50 KNOWN BUGS for extstorage
52 - gnt-backup export doesn't work because extstorage snapshoot hook are not available
53 - gnt-instance move works from somewhere to zfs, but not from zfs to somewhere
56 KNOWN BUGS for using -t plain on top of zfs
58 - cron/daily-block-snapshot snapshots are not correctly renamed
