I have a raid5 array that contain 4 disk and 1 spare disk. now i saw one
disk have sign of going fail via smart log.
Better safe than sorry... replace the failing disk and resync, that's
all.
You might want to do cat /dev/md# /dev/null, or cat /dev/hd?
/dev/null first. This is
I can think of two things I'd do slightly differently...
Do a smartctl -t long on each disk before you do anything, to verify
that you don't have single sector errors on other drives
Use ddrescue for better results copying a failing drive

other disks and write to the new disk. when
