to add hard drive to fstab


I recently rebuilt a system by replacing the boot drive.
and installe opensuse 12.1 64bit from the dvd.
all is well.

but here is a thing I also have 3 1TB drives that are raided together in this box.
When I did the install mentioned above these (all 3 ) were unPowered so they were not 'seen'

I have looked at my fstab and did some googling..
i am rather certain that i need to add ( loosley speaking )
mount by id##bigIdNum### 1 1.

so my Q is how do do a 'probe' to see that id num

also.

i have a copy of my PRevious fstab..same machine , smae raid cntrler same 3 drives... would the id ###bigIdNum be the same? seems like it should be.

so that line in my previous fstab ---should work?

thanks

The "id ###bigIdNum" is called UUID and is only set to a new value when you format the partition, so your previous line should work.

To check the UUIDs type:
Code:
ls -l /dev/disk/by-uuid

I tend to run 'fdisk -l' which provides an output something like this:

Device Boot Start End Blocks Id System
/dev/sda1 2048 206847 102400 7 HPFS/NTFS/exFAT
/dev/sda2 206848 138618879 69206016 7 HPFS/NTFS/exFAT

/dev/sda10 1191688192 1204279295 6295552 82 Linux swap / Solaris

The output from "ls /dev/disk/by-uuid/" looks like this:

0b97651a-5f2b-4872-9463-35937194bde7 95309357-232d-49f2-9b2f-5eb8156ab882

84c2a6e0-c2a4-49e2-beeb-e3e84c7cf684

It is difficult to marry the two together.

However, SuSE has used, for some time, /dev/disk/by-id/. The output from "ls /dev/disk/by-id/" looks pretty much as follows:

ata-SAMSUNG_HM641JI_S26XJ9AB526974

wwn-0x50024e920551987c-part8
wwn-0x50024e920551987c-part9

and the entries in "fstab" will be (sort of) as follows:

/dev/disk/by-id/ata-SAMSUNG_HM641JI_S26XJ9AB526974-part10 swap swap defaults 0 0
/dev/disk/by-id/ata-SAMSUNG_HM641JI_S26XJ9AB526974-part5 / ext4 acl,user_xattr 1 1
/dev/disk/by-id/ata-SAMSUNG_HM641JI_S26XJ9AB526974-part9 /home ext3 acl,user_xattr 1 2

This is obviously a much easier way of seeing what's going on.

Also, I like to set up my various removable devices as I want. If you plug them in and run "/dev/disk/by-id/" you can find the name, create the entry in "fstab" and create the directory "/media/SanDisk16gb" (for example - see below).

There is a problem, however, with SuSE.12.1. For me, at any rate, the directories created in "/media" are not persistent; reboot and they are gone. I've created a "MkDir" script with lots of "mkdir /media/??????????" lines in it to get over this.

Maybe somebody knows a better way?

Hope this helps.

As tobiSGD said, the UUID is assigned to a partition when the partition is formatted. Be aware that if you ever need to replace the drive the UUIDs of the new drive will be different (why I don't use UUIDs).

Another method of mounting is to use labels when formatting. The fstab entry would then be something like: "LABEL=boot /boot ext4 acl,user_xattr 1 2" (for a separate boot partition)". See manpage for mount options.
