Public bug reported:
I have two 500GB hard drives in a software mirror array using nVidia's
RAID controller build-into my P7N-SLI Platinum motherboard.
/dev/mapper contains the following:
[code]
crw-rw---- 1 root root 10, 60 2008-10-17 02:05 control
brw-rw---- 1 root disk 254, 0 2008-10-17 02:05 nvidia_cfffhefc
brw-rw---- 1 root disk 254, 1 2008-10-17 02:05 nvidia_cfffhefc1
[/code]
The RAID 1 device is comprised of two drives:
[code]
brw-rw---- 1 root disk 8, 16 2008-10-17 02:04 /dev/sdb
brw-rw---- 1 root disk 8, 17 2008-10-17 02:04 /dev/sdb1
brw-rw---- 1 root disk 8, 32 2008-10-17 02:04 /dev/sdc
brw-rw---- 1 root disk 8, 33 2008-10-17 02:04 /dev/sdc1
[/code]
Specifically, it's using /dev/sdb1 as the primary drive, and /dev/sdc1
as the secondary drive.
I am using a custom kernel due to a bug that I previously reported
having to do with slow hard drive access. It's version is '2.6.26.5'.
Here's the output of lsmod:

Restarting dbus via the command, 'sudo /etc/init.d/dbus restart' seems
to fix the problem, but makes some other things buggy until I restart
the computer. (I don't remember which things get buggy; it's kind-of
random.)
In Removable Media (Places menu), I have the following entries:
Floppy Drive
WinVista
WinXP
20.5 GB Media
PERSONAL (incorrect entry for mirror)
PERSONAL (incorrect entry for mirror)
PERSONAL (the correct entry for the mirror - automounted via fstab)
The last 'PERSONAL' entry has a different, lighter drive icon, and is
mountable, while clicking on the others produces the following error:
Unable to mount the volume 'PERSONAL'.
Details
mount: /dev/sdb1 already mounted or /media/PERSONAL_ busy
This makes sense, since it's the wrong partition to be mounting.
Here's my fstab entry for the mirror:
[code]
# PERSONAL
/dev/mapper/nvidia_cfffhefc1 /media/PERSONAL ext3 defaults,relatime,acl
0 0
[/code]
This has been an annoyance, since I often forget which drive to click on
and get an error message instead of the drive's contents. Any
suggestions would be well-appreciated.
Please let me know if you need any more details.
Thanks.
