Panic: page fault errors and possible disk corruption

[Shotgun84]

This is my first post, sorry if it's to long, but I thought it would be better to provide as much information as I could.

I'm getting "panic: page fault errors" on boot and need some help on what steps to take. I think my disks are possibly corrupt and I'd like some guidance on how to investigate and recover my data. Also being I'm running such and old version should I upgrade to troubleshoot or stick with the current version?

I've tried basic troubleshooting like using a new USB key (with a config backup) and I get the same error. Also when I run the system with default setting (i.e. no disks or raid details) the system runs fine making me think the issue is with the disks (or config).

Please note my config file refers to ad12, ad13 & ad14 rather then ad04, ad05 & ad06 (which is what the disk are called when I load with default settings) and I'm running a very old version of the software: 0.7 Khasadar (revision 4919).

Here is an image of my disks:


On load (with default or config) the console displays the following messages:

GEOM: ad4: corrupt or invalid GPT detected.
GEOM: ad4: GTP rejected -- may not be recoverable
GEOM: ad5: corrupt or invalid GPT detected.
GEOM: ad5: GTP rejected -- may not be recoverable

My system information is:

Hostname freenas.workgroup

The panic/error message when is crashes/reboots is:

Automatic reboot in 15 seconds - press a key on the console to abort.

For some quick context I built the server (at the time called FreeNAS) with a three disk RAID5 array back in 2009 to backup important data prior to travelling and working abroad for approx 3.5 years. On return the server worked great and I backed up a heap of data. Two years ago when moving house I essentially put the server into storage due to limited apartment space. I recently decided I want to move my data to cloud storage and I'm now getting errors.

Please help me.

Thanks,
Nick

save your valuable data in a safe place eg: cloud.

1- consider a new hardware 64bit cpable.

if yours is 64 bit capable , do a fresh embeded install on latest N4F and configure all from scratch, DO NOT import old config.

use button in webGUI "Clear config & import disk" and "clear config and import software RAID Disk". to import your pool.

Thanks for the response raulfg3. I've providde my hardware details below and know the CPU is 64 bit so I assume the motherboard and ram would be too... I'll download and install the latest N4F and give it a go!

Hardware Details
MB: Gigabyte G41M-ES2L F6
CPU: Intel E5300
RAM: 2x 1GB DDR800

Is there a guide for adding an existing RAID5 array so I don't accidentally destroy the data?

Thanks,
Nick
