So, randomly when I ran off to the bank today my server crashed.

Not a normal crash.........

A serious, won't let me reboot kinda crash.

I have no one to turn to til morning and have some serious files that went down that I REALLLLLY need tomorrow.

So, I'm trying my best to figure things out here.

The info I can provide you with;

Running FC10 x64,

(2) Quad Xeon 2.33ghz,
16gigs of 667 ram (I ran memtest and my ram passed after 4 hours no problems....)
Older ATI Radeon 7000 series 32mb Vid card,
3ware 9690 raid card running two raid array' - First array is the system OS mounted at / running two 640gb WD drives in Raid1 - Second array is fileserving array, strictly for rendering and copying image sequences and projects to for vfx. This array is 8tb in Raid6, so 5.45tb of storage.


And now the problem.

When FC10 boots up (when I restart it manually), since the crash I get to the login screen, then it brings up my username: Exile Entertainment Corp and I put in my PW, KDE selected as default, and BAM, nothing, just black background with the loading icon, no GUI, just the loading icon on the mouse. Finally after about a minute it kicks me back to the user login. So, I tried GNOME, which at least produced an error for me;

it read......



So, I now, can see my fileserver still listed on the network, viewable by others on the network, but is totally inaccessible

I also now see when the 3Ware Bios screen comes up on startup that my Raid6 array is 'verifying' ..... ?

The 640gb, only 200gb is used. The 8tb raid 6, only 2tb is used.

I'm at a total loss, and I'm freaking out a bit, I'm worried there could be data loss, it looks/seems okay, but it scares me nonetheless because I don't know what to do



Thanks for any insight gang,

-Inso

One of your system partitions is probably full; log in from a console (why are you running a GUI on a server anyways?) and run 'df -h'; look for any partitions that are low on space (check particularly the /, /tmp, /usr, /var and /home mounts).

Perfectly normal. If you have your array set to 'Auto Verify' in 3DM2, then it will periodically check parity on the array to ensure that it's valid. I think a hard-reset also triggers a verify operation. Verifying does NOT mean any data has been lost.

Oh, and when you log into the console, log in as root rather than your normal user account. If a partition is filled up, root might be the only account that can log in.

Using GUI because I'm learning Linux, been reading books on it and so forth.

Baby steps.

Anywho, initial login I cannot '
authenticate user' for logging into root.


Try your method and take a look around Altered, thanks.

Sorry, not sure I understand this -- you can't log in as root, even at the console?

iirc when I was using ubuntu I couldn't log in as root either.
The only thing I could do as root was sudo when I was in my account and that was about it

Yes, but that was a (silly) design decision on Ubuntu's part, mainly because it's primarily a desktop OS. He's using Fedora Core anyways, which IIRC forces you to chose a root password during install.

(You should ALWAYS have the ability to log in as root on the local machine. There are a few reasons, but the main ones are that root's home directory is stored in the / partition, whereas user home directories are typically in /home, so if there's a problem mounting /home then none of your users can log in. Also, by default, most filesystems reserve a certain percentage of disk space for exclusive use of the root user, so if a user process inadvertently fills up a filesystem, root can still login to fix it.)

You can give yourself the ability to log in as root on Ubuntu by doing 'sudo passwd root' and choosing a password, BTW.

Okay, well I have an expert coming over with over 14 years in the Unix business. I just don't have the time to figure it out, we deliver a project Friday and I had to send my guys home this morning already....

Yeesh,

AR, I'll keep you posted and let you know it goes,

thanks for your help.

Good luck! It really just sounds like one of the system partitions is full, shouldn't take your consultant long to fix.

expert cancelled on me too, just me today :o

I'm trying a few other things now because, when I do a 'df -h' it hasn't given me back my 442gb of space yet after deleting the log file.... even after reboot.

File this away as a lesson for the future: "I shall always configure logrotate when I add new logging to my system."

My first guess would be file permissions. If you can't even boot as far as the login prompt, then boot into single-user mode to make the change.

Are you sure the file was actually deleted? If it was in use when you ran the rm command (e.g. if iptables was writing to it) it might not have actually been removed yet. Do an 'ls -l' on the file to see.

OoooooooookayFinally.

Had to track down my ol' Fedora disc so that I could remount my main boot system because the filesystem was coming up weird block sizes.

Fixed it ;)


THANKS AR, saved my ass

I don't need to be sued and fired by SciFi this week :)

Okay, now just to figure out how to bond my quad port NIC for performance boost!

http://linux.die.net/man/8/ifenslave

Basically you need the 'bonding' kernel module (should ship standard on most distros) and the ifenslave toolset (should either ship standard or be available as an official package). That's it, really. The tricky part is usually figuring out how to get your distro to set it all up properly at boot time.

Delete Image. Please use this feature thoughtfully.  Report this image 

If you just want to monitor bandwidth, iptables logs are way overkill. You could use a tool like Cacti to make nice (interactive!) graphs and it uses almost no disk space.

The screenshot I've attached (assuming the forum doesn't eat it) is an example of my Cacti installation.
