LVM is no less reliable on z/VM than it is on any other platform - but I wouldn't use LVM for my / filesystem on i386 either. In my experience, when you lose a PV and thus the entire VG with it - it's easier to recover the system when it still boots due to having / on a basic partition.
If you're using LVM and a PV drops for whatever reason - most likely a finger check by someone, somewhere - you'll have to boot the system with recovery media, mount the volumes, chroot in, then fix it. You can't just fix it in place. In distributed systems this might be less of a problem, since everyone mostly uses the onboard SCSI disks, and thus theres no one else but you that you have to worry about. In Z, all disk is out in a network of some type ( FICON or SAN ) and thus more people are involved, and some shops ( like mine ) have multiple admins doing storage management in a shared everything environment. That's why I'm a bit shy about LVM for / -- Jay Brenneman ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
