debian

[tlcscousin]

I am trying to learn Linux and setting up a debian box with software raid. A standalone install without raid works great but cannot get software raid to install when doing a fresh install.I have googled until i was almost blue in the face. Is there a book for beginners that actually covers linux a bit better? I have 5 or 6 books on linux and all just explain how to install without raid and none really cover much in depth.

Maybe you using the wrong search criteria, have you tried searching using "lvm raid".

I was able to find this withing a few seconds:

I have not looked for that particular search string, i was trying to setup the raid during the initial install in the GUI setup.

The above link is what i was using to start the install i managed to get it almost installed until i got to the updating the distro during setup and it locked at 19% updating tzdata.I tried quite a few things to get it to get passed that file which research seemed to point to a date time issue and ended up starting from scratch.
I can get the disks partioned and then when finishing the partition it gives me no root file system defined and fails there.
I have been asked to create a test install where we can place plesk to test their updates as every time we allow updates it kills something on the server actually running plesk. The person who setup the original server has moved on.

Howtoforge has lots of nice tutorials,

http://www.howtoforge.org/how-to-install-ubuntu8.04-with-software-raid1

As an example.
Not for Debian, but Ubuntu is very similar.

If it stops during updates You might want to try
another server as your update source.
Or wait and try later, the server could just be having problems
when you ran the update.

The update was during install so was not offerred any chance to back out. Did a wipe and reinstall and Raid says it is working but the big partition shows as not mounted and have to figure out how to mount and access it.Have raid set with 3 partitions per drive 1gb gor root system 8 for swap and 489 for files once i get it going. The system boots but the big partition shows in disks as unknown file system and says it needs to be mounted.
fstab does not show the third partition as there so i assume its something i need to edit fstab to fix.

 

[BadBigBen]

You could try mounting it manually first, to get it running, before you edit the fstab file...

e.g.

create a folder under your HOME folder, e.g. mkdir /home/user/bigp

then mount it: mount /sda3 /home/user/bigp

where /sda3 is the path to the big partion...

more info can be found at the man page:

The large disk would not mount and would not unmount was getting an error that the kernel was having issues with both md0 and md1 and suggested unmounting them to allow access. They would not umount either. Wiped the install out figured will try setting up weverything and then create the raid as per other documents i managed to find.
Hopefully by tomorrow i will be able to either report success or look for a bit more advice on the setup.
I looked at LVM but it doesnt quite fit with what we are trying to do.
