If you install on LVM, you can make backups that are at least as good as "yank the plug". If you have a database server that can flush and freeze on command (e.g. in the simple case MySQL), you can snapshot the filesystem and release the database. This takes just a moment (no shutdown required). The only thing you can't currently do with Linux LVM is to freeze and snapshot all filesystems simultaneously. So, if you have actively updated data spread across multiple filesystems, it may not work the way you want. The only filesystem where you can't use LVM is /boot, but I mount /boot read-only except when loading updates, so it is always consistent. -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
