I've successfully got as far as step 5 and hit a problem, since trying to unmount that volume group tells me that / is in use. Trying step 6 warns me that running e2fsck on a mounted filesystem can cause severe damage, at which point I chicken out. Is it safe to skip to step 7 and run resize2fs without unmounting the filesystem first or should I be doing something different? This may or may not work, but it's safe and it'll just refuse to do it if it can't: # ext2online /dev/VolGroup00/LogVol00 You don't need to unmount the partition; in fact it won't work if you do. This assumes you're using an ext2 or ext3 filesystem. Paul. -- Paul Howarth <paul@xxxxxxxxxxxx>
