(/dev/sdwhatever instead of /dev/md6 directly?) Is there a reason or personal experience you have to not to resize the RAID-5 directly? I completely trust you as to date I cannot remember anything you suggested I do that wasn't a good way to do it but doing /dev/sdwhatever seems problematic if it had been an 8-drive RAID-1 becoming a RAID-5, etc. - Mark <quote> Using cfdisk or fdisk, delete the partition and recreate it, USING THE SAME START BLOCK at a larger size. Then "resize2fs /dev/sdwhatever" will resize the filesystem to fill the partition. </quote>
