Please tell me where I can pay for some linux phone support


To be blunt, other forums have just ignore a very important question that I've had for a small business linux server. Their RAID5 array is offline, and I'm willing to pay somebody to help me over the phone. It'd probably be a very easy solution for a linux expert, but I just don't know how to fix my problem.

From my original threads:

"I had a 4 disc array, built with mdadm. One drive failed but the array still mounted (as it should). Installed a new 4th disk and started the rebuild process.

About 30 minutes into the "rebuilding" it became obvious that my replacement drive was faulty. I had to restart the system to pull the drive, but I couldn't get the process to stop, and I had to do a cold shutdown.

Now, when I reboot, I can't get dev/md0 to mount, even on 3/4 working drives.

I have no idea what to do! Is this because I didn't unmount cleanly? Somebody P-lease help me

Edit: last error message before bootup is interruptec:
fsck.ext3: Invalid argument while trying to open /dev/md0"

P.S. I'm not looking charity. I am willing to pay to have this professionally done.

You probably need to re-setup the 4 disks in the RAID config of the card somehow. Right now, there's no volume defined in the RAID card. The RAID card is telling the driver it doesn't have any volumes.

You set this up when booting the server and hitting F1 (or whatever) to enter the RAID BIOS when it flashes the message as the system is bootstrapping. It needs to be set up here before the driver can see the drives when the OS loads the driver.

The place to go for support on this is the RAID card manufacturer's site because this isn't a linux issue. Once you've fixed your volume, linux won't have a problem mounting and using it. You'd have the same issue on Windows XP or server 2003 after breaking a volume set. The only people that can help are people that are familiar with your RAID card. I'd start with the Mfgr's site and forums. RAID cards are all sort of the same, yet different in subtle ways. The mfgr is the only place you'll find help unless you have some dumb luck.

Not that I'm an administrator or anything (developer), but I've dealt with enough RAID cards and done enough similar stupid stuff to them to know what's happening to you. As a developer you tend to trash your fair share of systems 8D Blowing things up is a great way to learn.

Thank you for replying to me.

Unfortunately, this is a strictly software RAID, created with mdadm. The ports on the motherboard are SATA running in standard mode. The volume is purely built on software using MDADM.

Still, the fact that you took the time to respond means a lot. Thank you.

Well, depends on the distro. If it's Redhat (or Novell ?, or maybe an IBM reseller) you could buy a support ctc.
Otherwise, you'd have to google for Linux support companies I think.

I tried to call RedHat and purchase support but they said that even if I DID purchase support, they wouldn't help me with Fedora. So much for being under Redhat's wing.

Fedora is a comunity proj sponsored by RH (or words to that effect). As you discovered, they only support the RHEL.
Fedora is deliberately bleeding edge, so don't use it in prodn.
If you want a free prodn ready system, use Centos (RHEL without the RH logos or support).
