Greetings. I am using a HighPoint RocketRAID 1820A controller with FreeBSD 6.0-RELENG and the hptmv driver. Six of the eight drives connected to the 1820A are in a RAID5 array. The other two drives are mounted as single devices, not part of any array. I am using these two drives as backup volumes. I can successfully umount one of the single drives, remove the drive, and insert a new drive: # umount /backup2 # from /var/log/messages: Mar 1 08:38:32 lance kernel: hptmv: Device removed: controller 1 channel 7 Mar 1 08:39:00 lance kernel: RR182x [0,7]: channel started successfully However, I cannot remount the new drive, even though it is already formatted: # mount -o rw -t ufs /dev/da2s1d /backup2 mount: /dev/da2s1d: Input/output error I then tried using fdisk and label from sysinstall, but neither let me write changes to the new drive. The only sure way I've found to swap and remount single drives is with a reboot. Is there another method that doesn't require a reboot? Thanks! dn
