# 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
