Hello,
I tried to kick off xfstests against btrfs on multipath device, e.g I set TEST_DEV="/dev/mapper/mpatha", which is a symlink to "/dev/dm-0". I mkfs.btrfs mpatha beforehand. Not related for the problem, but please use /dev/disk/by-id/.. on SUSE to work with multipathed devices.
When I run "./check 001", it said: " common.rc: Error: $TEST_DEV (/dev/dm-0) is not a MOUNTED btrfs 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 "btrfs" for /dev/dm-0.
I run "mount" and found that devtmpfs is mount on /dev/ ***by default***. Even though I run "mount -t btrfs /dev/dm-0 /somedir", df still showed devtmpfs.
Any ideas to kick off the xfstests?
