When I am shutting down the RAID= device md1 always failed. and when i issue raidstop --all /dev/md1 it says the device is busy or= resource busy. 2 Harddisk each has 3 partitions (1 /boot; 2 / ; 3 swap) partition 1 (/boot) is in RAID1 (/dev/md0) partition 2 (/) is also in RAID1 (/dev/md1) partition 3 (swap) How can I find and close all open files on md1 ?
