I am running Fedora Core 1 with stock RedHat kernel 2.4.22-1.2188.nptl. I filled my /usr/local to 100% and decided I needed some more space so I ran the lvextend and resize_reiserfs commands like I have done many times before to add a couple gig to the volume. A few hours later I began noticing very strange behaviors. My .vimrc file was filled with garbage. All of my email disappeared. Lots of filesystem errors began appearing on the console. I rebooted the machine and upon the reboot my entire /home logical volume was nowhere to be found. The /usr/local lv existed but the fs was corrupted very badly. I tried restoring the lvm config with vgcfg restore to no avail. I tested the memory with memtest and found no problems. I did a non-destructive badblocks test of all 80G of the drive with everything unmounted and / mounted RO and came up with no problems. The symptoms really look like disk was allocated improperly and diskspace already in use got overwritten. I have saved a bunch of output from various lvm commands and other things and the backup vgcfg file from right after I made the change which probably caused the damage in case they are of use to someone. They can be found here: http://ultraviolet.org/tmp Unfortunately I had to get the server back up and running so I didn't have time to try to reproduce it or do any more debugging although I am afraid to use lvm on this box now. I eventually deleted the corrupted lv's and remade from scratch and all seems well for the moment. I am SO glad to have made a backup a couple days before so I didn't lose too much. -- Tracy Reed The attachment is a digital signature. http://copilotconsulting.com More info: http://copilotconsulting.com/sig
