| # TEST: |
| # NAME: test_robind.sh |
| # FUNCTIONALITY: File system tests for normal mount, bind mount and RO mount |
| # |
| # DESCRIPTION: Performs filesystems tests for RO mount. |
| # For filesystem's like ext2, ext3, reiserfs, jfs & xfs. |
| # This test creates an image-file and |
| # a) mounts on dir1, |
| # b) mount --bind dir2 |
| # c) mount -o remount,ro |
| # It verifies the tests on a) and b) works correctly. |
| # For the c) option it checks that the tests are not able to write into dir. |
| # Then it executes the tests from flat-file {LTPROOT}/testscripts/fs_ro_tests |
| # Check the logs /tmp/fs$$/errs.log and /tmp/fs$$/pass.log for pass/failures. |
