How stable is lvm, is it good enough to put /usr /opt and the like on lvm disks?
I use LVM for /opt and /usr with Reiserfs file systems. I've added physical disks and extended the partitions (live, while they're still mounted) several times. Never a hiccup. Two warnings: don't put your root fs on LVM. It might work these days, but it used to be a source of problems. Second, don't use YaST. I have SuSE-8.1 and the LVM config stuff in YaST is extremely unstable. I never lost any data to it, but hit the "it's gone wrong - it might be best to reboot now" warning loads of times. The command line tools are very simple to use and have never given me a problem. -- "...our desktop is falling behind stability-wise and feature wise to KDE ...when I went to Mexico in December to the facility where we launched gnome, they had all switched to KDE3." - Miguel de Icaza, March 2003
