Ubuntu

Raid built with Bios not seen under /media.

Asked by peter b on 2008-01-15

Hello to all,

I had a Raid mirror (fake raid) set up under bios, formatted ntfs under win. Gutsy has seen it and mapped it under /media/sdb1 as well as displayed it on desktop as a drive identified with the win_label..

The other day I had to rebuild it and reformatted under win with ntfs.

Now Nautilus under /media/sdb1 shows no files on it and the desktop does not show it anymore. However, under Computer it appears as a drive with the win_label and under Nautilus it appears as file with win_label under /medial. On the task bar it appears as a drive with win_label and mounted. I did nothing on fstab.

It appears to me that by reformatting the uid for sure was changed, fstab seen the change and acted on it but somehow under /media/sdb1 and desktop it fell through the cracks so to speak.

Any idea how to get it back on the desktop and see the files on it under /media/sdb1? I tried gconf-editor but no success. I can live with the current situation but It would be nice to see it on the desktop again.

Any help is appreciated.

Regards,
peter b

Today I restarted Gutsy; on the console the message /dev/disk_to_disk followed by UID=...something, not present was displayed and at the end the message fail in red appeared.

Checking further, in /etc there are 3 files that refer to fstab as follows:

fstab --> current, created after raid rebuilt
fstab.pre-uuid --> created at install time, and
fstab.pre-ntfs-config --> created after the previous one probably after an update or ntfs-3g package install; I do not remember

In any rate, the statement that I made in the previous post that the uid was changed by reformatting is true --> the uid in fstab files (all of them) for /dev/sdb1 is the same; that makes the second statement that fstab seen the change and acted on it untrue hence the message on the console. So, I will proceed as follows:

So, I will proceed as follows:

1. make a copy of fstab just in case
2. obtain the new uid of the newly rebuilt raid
3. edit fstab with the new uid for /dev/sdb1
reboot and hope for the best.

Any comments re this course of action?

Success, everything is just fine after the actions mentioned in the previous post performed. The Raid icon is back on the desktop and the files are in /media/sdb1
