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.
Yes, unfortunately the yast1 LVM config was MUCH better than the yast2 one is... By the way, the Oracle 9iR2 RAC certification was run on raw I/O on LVM volumes... very simple to setup with LVM, very tough without! Michael
