I run mkfs on mpatha beforehand. When I run "./check 001", it said: " common.rc: Error: $TEST_DEV (/dev/dm-0) is not a MOUNTED ext4 filesystem " The I checked the script common.rc, and found that it uses df to determine the filesystem type and it uses the realpath "/dev/dm-0" instead of "/dev/mapper/mpatha", while df always shows "devtmpfs" instead of "ext4" for /dev/dm-0. I run "mount" and found that devtmpfs is mount on /dev/ on opensuse ***by default***. Even though I run "mount -t btrfs /dev/dm-0 /somedir", df still showed devtmpfs. Any ideas to kick off the xfstests? thanks,
