I was using a Reiserfs on RAID1 - had to resize the raid after repartitioning the disks and hot adding them to the raid by using mdadm --grow /dev/md1 --size=max then unmount the /dev/md1 then run resize_reiserfs /dev/md1 this resyncs the disks/raid - to speed up the process I used echo 200000 > /proc/sys/dev/speed_limit_max echo 200000 > /proc/sys/dev/speed_limit_min Thanks for the article - very useful!
