Hi Guys, I have just grown my raid 5 from 7 to 8 500Gb drives. I am now running into this problem. When I try to run fsck /dev/md0 I get the following: fsck.ext2: Device or resource busy while trying to open /dev/md0 Filesystem mounted or opened exclusively by another program? Or when I try to run resize2fs /dev/md0 to make use of new drive, I get the following: resize2fs: Device or resource busy while trying to open /dev/md0 Couldn?t find valid filesystem superblock. Cat /proc/mdstat outputs: Personalities : [raid6] [raid5] [raid4] md0 : active raid5 sdb1[0] sdi1[7] sdg1[6] sdh1[5] sdf1[4] sde1[3] sdd1[2] sdc1[1] 3418686208 blocks level 5, 256k chunk, algorithm 2 [8/8] [UUUUUUUU] unused devices: <none> However, I can still access and mount my filesystem - I just cannot grow it, which I find very strange. I have tried to init 1, to go to single user mode, and I have made sure file system is unmounted, but this ?busy? error still occurs. Any ideas? I?m kinda stuck. Google is no help! I am running fedora core 7. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
