Still more problems ... :( My md raid5 still does not always shut down cleanly. The last few lines of the shutdown sequence are always as follows: [...] Will now halt. md: stopping all md devices. md: md0 still in use. Synchronizing SCSI cache for disk /dev/sdd: Synchronizing SCSI cache for disk /dev/sdc: Synchronizing SCSI cache for disk /dev/sdb: Synchronizing SCSI cache for disk /dev/sda: Shutdown: hde System halted. Most of the time the md array comes up clean on the next boot, often enough it does not. Having the array rebuild after every other reboot is not my idea of fun, because the only reason to take it down is to exchange a failing disk. Again, help appreciated - I don't dare putting the system into "production" like that.
