sBlatt's questions

Yesterday, one hdd of my LVM crashed (smart-error)

The Machine has the following setup:
- 4 hdds
- 1 Partition Raid10 (System, 4*50GB)
- 1 Partition normal (/boot, 200MB, sda)
- 1 Partition LVM2 (Data, 4*~850GB)
- Ubuntu 10.04 Server (headless)

Now my lvm won't mount anymore, Ubuntu asks me to skip or manually recover on bootup. When I press S the system starts, but without my lvm getting mounted.

Now my system partition does not seam to be affected (/proc/mdstat looks as usual) an /boot works fine, too.

What I will try now is to
- buy a new hdd
- Integrate the hdd in my lvm
- Try to remove the sda-part of the lvm (copy it over to the new sde, or whatever lvm wants)
- Do the raid stuff (I think I'll find out how to do that, otherwise I'll ask a separate question)

Now my problems:
- How can I remove sda from the lvm (remove meaning copy contents and mark partition as not in use so I can unplug the drive)?
- If I am not able to remove the partition normally, are there any tools to recover the files on this partition, so I could manually copy them to the "new" lvm?

Thank you for your help

EDIT:
separated solution from Question

Is it possible (and how) to use a computer headset (or speakers+mic) as a hands-free device for my mobile? I bought a bluetooth-dongle but I couldn't get it to work yet. I think I already set this up on an older version of Ubuntu on my laptop.

I'm using Ubuntu 10.10, the phone is an android 2.2 (but I think this doesn't matter) and the bluetooth device is a Integrated System Solution Corp. Bluetooth Device (according to lsusb).

Output of lsusb -v

EDIT: I found a project that seams to do just what I want: http://nohands.sourceforge.net. I tried to install it on my laptop but it didn't work. I'll try it again on my computer at home and post a description as soon as it works (or any of you guys could post a solution if you're faster;)

Edit2: I was able to connect my phone, but somehow the audio doesn't work. I think the program has troubles with pulseaudio, as the soundtest fails. Any ideas?

Edit3: I'm still trying to get this to work. I might buy another bluetooth dongle. ATM I'm able to dial numbers in hfconsole - that's all. Somehow I'm shure there is a way to get this to work!

I'm currently (for some days now) having the problem, that my Ubuntu clock runs too fast. and by too fast I mean like: last time I adjusted it was at 4 PM, now (10:25 PM) it shows 10:57 PM ! Any ideas how to fix that?

Could it have something to do with handbrake? (I'm currently ripping my DVD collection, so handbrake is always running).

My System:

Ubuntu 10.4, all updates, handbrake from getdeb (0.9.4 I think), Intel Core2Quad, 4 GB Ram, NVidia GTX 260 (195.36.24 according to nvidia-settings)

Output of dmesg
Output of cat /proc/interrupts

Output of cmdline:
