#
# run_seed_to.sh - Run ceph_test_filestore_idempotent_sequence up until an 
# injection point, generating a sequence of operations based on a
# provided seed.
#
# We also perform three additional tests, focused on assessing if 
# replaying a larger chunck of the journal affects the expected store
# behavior. These tests will be performed by increasing the store's
# journal sync interval to a very large value, allowing the store to
# finish execution before the first sync (unless the store runs for
# over 10 hours, case on which the interval variables must be changed
# to an appropriate value). Unless the '--no-journal-test' option is
# specified, we will run the 3 following scenarios:
#  
#  1) journal sync'ing for both stores is good as disabled
#     (we call it '00', for store naming purposes)
#  2) journal sync'ing for store A is as good as disabled
#     (we call it '01', for store naming purposes)
#  3) journal sync'ing for store B is as good as disabled
#     (we call it '10', for store naming purposes)
#
# All log files are also appropriately named accordingly (i.e., a.00.fail,
# a.10.recover, or b.01.clean).
#
# By default, the test will not exit on error, although it will show the
# fail message. This behavior is so defined so we run the whole battery of
# tests, and obtain as many mismatches as possible in one go. We may force
# the test to exit on error by specifying the '--exit-on-error' option.

#     specify differente store names such as 'a.$seq' or 'b.$seq'.

#     three additional tests for each store, and we will reuse the same
#     command for each one of the runs, but varying the store's name and
#     arguments.
