The use of run_check() immediately stops a test because it calls the _fail() function when execution of its argument fails. This is generally not encouraged in fstests as it prevents a test from detecting further problems after that failure. Since the next patch in this series updates other tests to use _run_btrfs_balance_start() for which a failure to run balance can be expected (btrfs/187 for example), remove the use of run_check() from _run_btrfs_balance_start(). Existing tests that use _run_btrfs_balance_start() now redirect standard output to the test's .full file for debugging purposes. In case balance fails the tests will fail due to unexpected output from the standard error.

# This test verify the RAID1 reconstruction on the reappeared

# 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
