    Hi,

    I've recently installed CentOS 5.3 with software raid (1) and other useful and time consuming stuff. Everything besides hot swap is working fine.
    Hardware supports it. It's Intel S5000PAL motherboard.
    When I plug in a sata disk while the system is running nothing seems to happen. dmsg and /var/log/messages does not show anything.
    Also if I unplug a disk while the system is running it crashes.
    What could I do?

    Thanks in advance.

    I don't think you can use hot-swapping with software RAID.

    So when one of the disks fails the system will just crash instead of switching to the second drive ?

    No, the system will continue to work fine, but you will have to shut it down to insert a new hard drive.

    I guess that will have to do.

    Thanks for the information :)

    One more thing.
    Does that mean I wont be able to hot swap any other disks that are not in raid ?

    I don't think hot-swapping will work unless the disks are in a hardware RAID.
