[SOLVED] 2 TB drive seen in BIOS, not seen in Mint

Postby carlcarl on Fri Feb 08, 2013 5:35 pm

I have a Linux box I use for file storage. I built it a few years ago with another distro (PCLOS), and it worked well enough. It was configured with a 40gig HD for the OS, and a RAID card running 5 500 gig drives for data (roughly 2 TB usable space). This showed up in PCLOS as a single ~2TB drive, as it should.

Recently the OS drive died. Complete failure. I replaced the drive and installed Mint 10 Julia (because it fits on a CD). My BIOS sees the RAID drive as usual, but Mint does not see the RAID drive at all.

What's worse, it did at first. For about a day. Now it does not see it at all. Hmmm. Grain of salt time. My wife says it did, but I don't recall...

Following directions in another thread, I've run the following commands with these results:

Code: Select all
carl@NAS2 ~ $ sudo parted /dev/sda print
Model: ATA WL40GBSATA (scsi)
Disk /dev/sda: 40.0GB
Sector size (logical/physical): 512B/512B

While I don't pretend to understand all of that output (I'm a newbie), I do see a distinct lack of references to the 2 TB drive that is seen by the BIOS.

Where do I go from here?

I should add this info:


Code: Select all
CPU[-Single core Intel Celeron D (-UP-) clocked at 3457.707 Mhz-] Kernel[-2.6.35-22-generic x86_64-] Up[-2:12-] Mem[-427.2/2008.7MB-] HDD[-40.0GB(6.5% used)-] Procs[-148-] Client[-Shell-] inxi[-1.4.12-]

Does the array show up if you type:

Code: Select all
sudo parted -l

and/or
Code: Select all
sudo fdisk -l

(Lowercase L on both)

Also, what Motherboard and Raid card are you using? It could be a simple BIOS setting or boot order setting that is causing it to be missed.

No, it doesn't show up there, either, but in checking just now, I found my BIOS settings are off from what I had set yesterday. I verified all my boot order settings, etc., yesterday, and noticed that the clock was way off. I corrected it, and it's way off again this morning. Also, BIOS is NOT seeing the RAID card today.


Looks like a CMOS battery is dying (I hope). I'll get that corrected before I take up any more of your time! That might be the whole story.

Thanks!

That would be an easy fix. :wink: Let us know if it works out. If not, let me know the MB and Raid card type.

I know that drained CMOS batteries can drive people mad, especially Laptop owners. It's amazing what a buck fifty battery can fix.

That was it!

Sorry to be so long posting back - I've been really sick and didn't get to this.


Replaced the CMOS battery, booted up, logged in, and there is my RAID with all my data. Yay! :D


Nice to know I can lose the OS drive, replace it and install a DIFFERENT OS, and still have my data back.

It's a Netcell Revolution card, BTW. Cheap consumer grade RAID, and no longer made. But it works!


Thanks for the help!


I'm building another NAS soon, and this time I'm going with an enterprise grade card from fleaBay, but I'm glad to know this cheapie is working!

No prob. Wasn't worried. The more I thought about your last post, the more I was convinced that a new cmos batt would fix it. Now you've got me thinking that I could use a NAS.
