fully automatic script to install Debian 11 with ZFS root on Hetzner VPS
|
||||
WARNING: all data on the disk will be destroyed
|
||||
How to use: add SSH key to the rescue console, set it OS to linux64, then press "mount rescue and power cycle" button
|
||||
Next, connect via SSH to console, and run the script
|
||||
Answer script questions about desired hostname, ZFS ARC cache size et cetera
|
||||
To cope with network failures its higly recommended to run the script inside screen console
|
||||
screen -dmS zfs
|
||||
screen -r zfs
|
||||
To detach from screen console, hit Ctrl-d then a

fully automatic script to install Ubuntu 20 LTS with ZFS root on Hetzner VPS
|
||||
WARNING: all data on the disk will be destroyed
|
||||
How to use: add SSH key to the rescue console, set it OS to linux64, then press "mount rescue and power cycle" button
|
||||
Next, connect via SSH to console, and run the script
|
||||
Answer script questions about desired hostname and ZFS ARC cache size
|
||||
To cope with network failures its higly recommended to run the script inside screen console
|
||||
screen -dmS zfs
|
||||
screen -r zfs
|
||||
To detach from screen console, hit Ctrl-d then a
