These images contain various forms of corrupted filesystem which
|
|
e2fsck will correct. They are used as a regression test for e2fsck.
|
|
|
|
The test_script program will automatically run e2fsck against the
|
|
filesystem images. It will run them two times, and display the exit
|
|
status for each run. The meaning of the exit status codes are as
|
|
follows:
|
|
|
|
0 No filesystem errors were detected
|
|
1 Filesystem errors detected, but corrected
|
|
2 System should be rebooted
|
|
4 Filesystem errors left uncorrected
|
|
8 Operational error (generally means internal error,
|
|
or filesystem error that the e2fsck was not
|
|
prepared to deal with)
|
|
16 Usage or syntax error
|
|
|
|
During the regression test, the first exit code should be 1, and the
|
|
second exit code should be 0. In other words, all (with one
|
|
exception) of the test filesystems in this directory have some sort of
|
|
filesystem corruption, which e2fsck should fix on the first pass.
|
|
After the first pass, e2fsck should leave a fully consistent
|
|
filesystem with no detectable errors found in the second pass. The
|
|
exception is the okgroup.img filesystem, which contains no errors, and
|
|
so both exit codes should be 0.
|
|
|
|
NOTE: It appears that at least some versions of the original e2fsck do
|
|
not exit with an exit status code of 1 after correcting filesystem
|
|
errors. So if you modify the test_script to try running these
|
|
filesystems against the original e2fsck, you will have to inspect the
|
|
test_script.log file manually.
