Software Raid Debian 8

Postby justong1979 » 2017-10-23 23:24

Hello,

Im trying to setup software raid using Debian 8, 2 hard drives (250GB each) and instructions provided by http://www.iprobot.net/linux-tutorial/how-to-setup-software-raid-in-debian-ubuntu/ but im running into issues and I need some guidance.

Per the instructions I so far have things configured as follows:

Code: Select all
SCSI4 (0,0,0) (sda) - 250.1 GB ATA FUJITZU MJA2250B
#1 primary 98.6MB B K raid
#1 primary 1.0GB     K raid
#1 primary 249.0GB  K raid

SCSI5 (0,0,0) (sdb) - 250.1 GB ATA WDC WD2502ABYS 0
#1 primary 98.6MB B K raid
#1 primary 1.0GB     K raid
#1 primary 249.0GB  K raid


The problem comes when I "Finish partitioning & write changes" I get the error:
Code: Select all
No root file system is defined
Please correct this from the partitioning menu


What am I missing here? Thanks for the help!

You created 3 sets of RAID partitions, so I guess you want to create 3 RAID arrays.
Did you create the RAID arrays by entering the RAID configuration item ?
Did you configure each array and assign a contents type, mount point and so on... as you would do with plain partitions ?

Then I advise that you read a bit about the Linux RAID basics.
Prefer wikis over tutorials, because the latter often describe how but do not explain why.
A good starting point is https://raid.wiki.kernel.org.
