In Windows, you can leave it in that state for days and it will come right back. Linux on the other hand will eventually run itself out of memory and slowly die. If you're booting locally but using SAN attached volumes, it'll probably panic if it needs that particular file system. One of my favorite demonstrations was running I/O against a storage system, shutting down the storage, waiting 10 minutes, bring it back up and the OS has no idea the SAN was down. Pretty resilient stuff. Brian
