You're trying to mount root on an XFS partition. Maybe your kernel doesn't
support XFS?

XFS was used on the RaQ 550 model only. Since the server is unable to mount the root filesystem, it would appear you have some kind of disk error (bad drive, controller, missing files, etc.)

Can you give some more info about your server's configuration (model, OS version, what you did prior to getting this message, etc)?

my box is a Raq3 running the RaQ550 OS. It was working fine 2 weeks ago, I actually travelled so i left it on for a whole week. when i got back, the Admin UI from the web browser was unresponsive so i decided to reboot the machine, which brings us to the above message (recursive reboots when it gets to that point)...
I replaced the original 10gb HD that came with it with a 40GB drive to fit my needs. the machine has 512Mb Ram. Is there any way of running xfs_repair on the cobalt? I'm very new to these boxes. I hope the information helps

[BruceT]

I don't know much about XFS and its tools, but it would seem that anything you try that works is better than nothing. You will probably need to pull the drive and stick it into a plain PC or something in order to run the repair tool... (maybe boot the PC from a Knoppix Live CD - I think that has XFS support)

Thanx BruceT, i guess that's my only option... do you know of anyway to change the filesystem? i don't know the other types yet but ext3 works perfectly for me... any help?

[BruceT]

No good way to change the filesystem and keep the rest of the OS stuff the same, AFAIK. I think there is some kernel-level stuff tied up with the filesystem type, so I doubt that it's easy to "switch" to an alternate...
