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. 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? thanks, -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
