IMPORTANT: this change has a docs/UPDATING entry! This rename is unfortunately necessary because NetBSD has decided to create its own service(8) utility, and we will want to import theirs as well. The two can obviously not coexist. Also move ours from /bin to /sbin, as it is a superuser-only utility. Change-Id: Ic6e46ffb3a84b4747d2fdcb0d74e62dbea065039

# This test set tests the some of the basic functionality of the Faulty Block
|
|
# Device driver. It takes a writable device as input - a small (sub)partition
|
|
# suffices for this purpose. All information on the given device WILL BE LOST,
|
|
# so USE AT YOUR OWN RISK.
|
|
#
|
|
# Currently, a reasonable subset of supported read and write fault injection is
|
|
# tested. Since injection of write faults was the original goal for this
|
|
# driver, the test set for this part of FBD functionality is relatively large.
|
|
#
|
|
# Testing of read faults works as follows. First, a known pattern is written to
|
|
# the actual device. Then FBD is loaded as an overlay over the device. A fault
|
|
# injection rule is set on FBD, and the disk pattern is read back from the FBD
|
|
# device (/dev/fbd). FBD is then unloaded. The test succeeds if the pattern
|
|
# that was read back, matches a certain expected pattern.
|
|
#
|
|
# Testing of write faults works as follows. First, a known pattern is written
|
|
# to the actual device. Then FBD is loaded as an overlay over the device. A
|
|
# fault injection rule is set on FBD, and another pattern is written to the FBD
|
|
# device (/dev/fbd). FBD is unloaded, and the resulting disk pattern is read
|
|
# back from the actual device. This resulting pattern should match a certain
|
|
# expected pattern.
|
|
#
|
|
# Since all raw block I/O requests go through the root file server, this test
|
|
# set heavily depends on the behavior of that root file server. It has been
|
|
# tested with MFS, and may not work with any other file server type. It assumes
|
|
# that a 4K block size is used, and that the file server translates raw block
|
|
# requests to aligned 4K-multiples. The test set also makes assumptions about
|
|
# merging pages in write operations, flushing only upon a sync call, etcetera.
|
|
# Unfortunately, this dependency on the root file server precludes the test set
|
|
# from properly exercising all possible options of FBD.
