Attempts are rejected with "/dev/md0: Device or resource busy". Even shutting down to single user mode does not release the device for stopping. I had to reboot to single user mode, then I was able to stop it, unconfigure it, etc. Testing the throughput of Linux's software raid in levels raid1 and raid0 with various chunksizes was somewhat more tedious because of this problem... Here is my (current) raidtab: Raiddev /dev/md0 raid-level 0 nr-raid-disks 2 chunk-size 64k persistent-superblock 1 nr-spare-disks 0 device /dev/sda2 raid-disk 0 device /dev/sdb1 raid-disk 1 Thanks...
