When everything goes wrong....

I updated to F14 using the DVD. It seemed to complete everything ok but after rebooting I only got a blinking cursor.
I rebooted using the DVD a couple of times and chose upgrade and at the third attempt it booted to the OS but the only thing i saw was a blue and green screen....
I tried to connect using tightvnc on my pc (I had already set up remote desktop on F12) and succeeded. There from terminal I did a "yum update" and it seemed like it updated everything all over again... after that was over i updated amahi from 5 to 6 and the system rebooted ok and I could login straight on the server and not through vnc.
The first thing I noticed was that the autologin didn't work
The second was that when i opened my computer there was a hard drive which had a green dot with VG written inside and a label vg_amahi that couldn't be mounted ( i suppose it has something to do with the logical volume of the boot drive...)
The third was that greyhole was down. I found a command (mysql -u greyhole -pgreyhole greyhole < /usr/share/greyhole/schema-mysql.sql) and it worked so greyhole was on again. Unfortunately only temporarily as after a reboot it was off again and the command wouldn't do anything...

I'm pretty freaked out as you can imagine and i wish I hadn't done that upgrade but unless there is a miraclemaker among you i don't think my system can be salvaged.
So what I am wondering is can I make a clean install of F14-Amahi6 and then reconnect all my hard drives and have them recognized again? I have 6Tb of data plus the 1Tb boot disk and there is no way I can empty them one by one to add them as I did in the initial install because back then the 3x2Tb drives where new and i replaced with them the old 1Tb drives (which I gave away afterwards)

If I connect my drives to another linux system will they be readable? Can I do something to rearrange the data in them now that greyhole doesn't work?

I'm sure that a "How to" on a case like mine would be very useful on the Amahi Wiki as it would give help to anyone who's boot drive failed and needs a clean installation

I know that the obvious answer to my question would be "tough luck man... you should have made a backup". The truth is i backed up my personal data on an external drive but completely slipped my mind to do a backup of the boot disk... That would have solved everything!!

Anyway any help would be appreciated.
Thank you in advance.

P.S. The good thing is that everything is still accessible from my network PCs (suprisingly!!!!)

Day 2
Greyhole seems to be active again.
The hard drive still seems not to be recognised but I have access to all the files on it. (the user files basically that are stored on the first hard drive look ok)
Found a post on the greyhole section about re-recognizing everything after a new install but if greyhole continous to work i think I'll try solving the rest of the problems untill I'm sure at least that a clean install will surely recognize everything ok...
Any help would be appreciated!!!

I can absolutely vouch for the process described here:

Follow those steps to the letter and you'll have no trouble. I've done it twice, and the only issue I had was my own fault. I'd mistyped a share name when recreating them, which killed all the symlinks for the share. The data was still there though, and it was no big deal to feed it back in.

Good luck.

Thank you very much!!!
It sounds quite easy as well as safe.
I'd like to ask also if you can tell me the best way to organize a 1Tb boot disk.
It will be used only as a boot disk I have no intention of partitioning it and adding anything to the pool. Just the userfiles will be on it and i suppose GH will use it as temporary space, right?
Will this be ok for me?

I'm thinking 4Gb for swap, 1 Gb for boot, and the rest root.
Is that ok?

Would be good to add this procedure to the wiki (sorry, trying to catch up here!), under the Greyhole pages. Anyone interested in chipping in with that?
