The tests mount the second device in the device pool but never
unmount it, causing the next test to fail.
Example:
$ cat local.config
export TEST_DEV=/dev/sdb
export TEST_DIR=/home/fdmanana/btrfs-tests/dev
export SCRATCH_MNT="/home/fdmanana/btrfs-tests/scratch_1"
export SCRATCH_DEV_POOL="/dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg"
export FSTYP=btrfs
$ ./check btrfs/125 btrfs/126
FSTYP -- btrfs
PLATFORM -- Linux/x86_64 debian3 4.8.0-rc8-btrfs-next-35+
MKFS_OPTIONS -- /dev/sdc
MOUNT_OPTIONS -- /dev/sdc /home/fdmanana/btrfs-tests/scratch_1
btrfs/125 23s ... 22s

Ran: btrfs/125 btrfs/126
Failures: btrfs/126
Failed 1 of 2 tests
So just make sure those test unmount the device before they finish.

# FS QA Test 124
|
|
#
|
|
# This test verify the RAID1 reconstruction on the reappeared
|
|
# device. By using the following steps:
|
|
# Initialize a RAID1 with some data
|
|
#
|
|
# Re-mount RAID1 degraded with dev2 missing and write up to
|
|
# half of the FS capacity.
|
|
# Save md5sum checkpoint1
|
|
#
|
|
# Re-mount healthy RAID1
|
|
#
|
|
# Let balance re-silver.
|
|
# Save md5sum checkpoint2
|
|
#
|
|
# Re-mount RAID1 degraded with dev1 missing
|
|
# Save md5sum checkpoint3
|
|
#
|
|
# Verify if all three checkpoints match
