Many thanks for the "quick installer" and the recent updates<br>
Ensuring all the packages necessary are pre-installed<br>
Ensuring that the disk(s) are available and can be correctly mounted etc<br>
Else, for failures at disk set-up the script was not re-runnable<br>

**But what's happening here? Pls find the error and the response from fdisk**<br>

(c)ontinue with install, (m)odify options, or save current configuration and (a)bort? (c/m/a) [c]: c<br>

rubyhost: Unable to find disks: /dev/sdb5 from /dev/fd0,/dev/sda,/dev/sdb,/dev/sr0 and retry<br>

FATAL: all hosts have already failed -- aborting<br>
Host: rubyhost had 1 failures<br>
Control Nodes have failures. Please fix the failures and re-run the installation.<br>
