[SOLVED] LVM extend issue?

i built an old box the other night to toy with LVM, seemed like something cool to learn. anyway, there was data on 2 of the drives, a 320, and a 200, but i had another 320 that was empty, to i set it up first. set it to 100gb, then added 60 to see if it resized without losing anything, and added 60gb again. then tried to extend it to 100%, and thats where im getting the problem, it wont add anything after the first 220gb that are there. anyway, i had enough space to back up the other 320gb, and i added it to the volume, and tried to extend it to 100% again, and it still wont add anything after the first 220gb.

heres my terminal output anyway

Re: [SOLVED] LVM extend issue?

Searching on google for that error message turns up a few hits. A couple bug reports for other distros suggest unmounting the partition and then trying to resize. An online resize should work, so i suppose something is broken with the current e2fstools or the kernel..

Re: [SOLVED] LVM extend issue?

i ended up unmounting it and running e2fsck, it extended fine afterwards. i also added the third hard drive, and extended it again. totalling just under 800gb.........now i dont know what to do with the machine.
