this is a little OT, but the system is at least running FC2. i have an ibm X330 with a ServeRAID 4Lx controller (secretly a mylex controller). i have been running it with a pair of IBM SCSI drives (the ones supplied with it), in RAID 1. i recently decided i wanted to verify that rebuilding worked properly; i took a "IBM" hotswap unit (a Quantum of slightly larger capacity in an IBM tray) and swapped it in, first marking the drive it was replacing defunct using the IBM utility (the utility is for RH 9, but it seems to work ok in FC2). it appeared automagically go to rebuild mode as soon as it went in. it's two days later, and the drive is still rebuilding. just how long should such a rebuild take? anyone know? there are no error messages; the ibm RaidMan utility beeps every so often, but the drive is simply labeled "rebuilding" in its properties panel. richard -- Richard Welty rwelty@xxxxxxxxxxxxxxx Averill Park Networking 518-573-7592 Java, PHP, PostgreSQL, Unix, Linux, IP Network Engineering, Security
