Redhat or otherwise? 2) Anyone know how I can boot from a rescue CD, and get to a point where I can attempt to fsck the filesystem, or at least see where in bringing up LVM2 the system is getting confused? 3) Should I just write off the data on that filesystem as a loss and start over? I had/have a bunch of financial records, an opensource app I was developing, a pretty detailed html to palmdoc conversion setup, and on in the filesystem. Is this stuff is in a FAQ somewhere, please just tell me what to google for. I've google'd around already, and found essentially nothing. Yes, I know, I should keep backups. Thanks!
