It seems as if my /boot partition has failed on my system, was working fine, rebooted and got "Short Read Superblock" errors...
I have tried some basic linux troubleshooting, I have tried to assign the backup superblock, (e2fsck -b 8193 /dev/sda1) etc, but no avail.
I used the Rescue Cd, and it seems as if I am able to mount the other partitions ok, so I could recover data that way? Not sure how to do that though...
Unfortunately no usable backup to restore from either...

Not looking forward to a whole rebuild, as it took me weeks to get all the SPA configs, endpoints etc down right. Anyone got any ideas?
If I rebuilt Trix 2.6.2 to a new harddrive, could I copy the sip.conf (and other) files from the failed harddrive?

I am guessing you have never used the TBM Backup utility to backup your entire trixbox config?

If you could extract the conf files you could probably reuse these OK.

One of my boot partitions failed once and what I did was get my other linux server and burn grub to a disk. If your trixbox is up to date you should be able to use the current kernel on the cd and just set the root device as whatever your root device is.

Hopefully this will give you some ideas!

Use something like supergrub boot disk to try and boot your old trixbox perhaps? Or use a live cd, them image it (clonezilla, or just use dd).

Thanks everyone for all your help. I have picked up some new tools and tricks, so much appreciated.

What I did was rebuild onto a new hard drive. I then connected the old drive to my PC, and installed an ext3 Fs reader (Disk Internals Linux Reader) so I could read the files in windows.

I then opened the restored (/etc/asterisk) conf files with Winscp and basically copied and pasted the content into the live conf files.

It was a bit of a flakey process at times, but it got most of what I need.

I have now added the the tbm-backup module, which has been a fantastic find - thanks sbiddle. It helped, even with testing during the restore process.

I now want to try and sort out my incoming routes issue (another thread probably) which is what I started to look at when it all went pear shaped!
