I just received a new root server (this one) with the following drives:
Disk /dev/sda: 480 Gb
Disk /dev/sdb: 480 Gb
Disk /dev/sdc: 240 Gb
Plus the 240Gb SSD.
Both sda and sdb are set up on RAID-1 and what I want to do is setup Ubuntu 14.04 on the smallest drive (sdc: 280 Gb) and a PostgreSQL database on one of the other drives configured in RAID.
The server is started in rescue mode on Debian 7.0 Wheezy. My interface shows up like this:
root@rescue ~ #
I would like to know, from the rescue mode, how can I install Ubuntu only on the drive that I want and then exit the rescue mode?
For setting up postgres I already found a couple of tutorials;
- https://dba.stackexchange.com/questions/103261/point-postgresql-on-ubuntu-to-a-new-datadir
- https://dba.stackexchange.com/questions/43155/optimum-configuration-for-4-ssd-drives
- https://dba.stackexchange.com/questions/28926/moving-postgresql-data-to-different-drive
So it will be easy once the initial and most important OS setup is done.
The reason I want to do this
In the previous companies I've worked for, whenever there was an issue with the OS and we needed a repair or reinstall it, for safety measures the sys-admin team had to burden with moving all non-OS data into a different drive while the repairs were made.
I found this guide, but as it says in the beginning, it may 'break' my system which is exactly what I don't want to do!
I want to make sure I install Ubuntu in the correct drive, from rescue, and boot it afterward from my installed OS, so that I can continue with my PostgreSQL installation on a different drive.
