| # FS QA Test No. 083 |
| # |
| # Exercise filesystem full behaviour - run numerous fsstress |
| # processes in write mode on a small filesystem. NB: delayed |
| # allocate flushing is quite deadlock prone at the filesystem |
| # full boundary due to the fact that we will retry allocation |
| # several times after flushing, before giving back ENOSPC. |
| # |
| # Note that this test will intentionally cause console msgs of form: |
| # dksc0d1s4: Process [fsstress] ran out of disk space |
| # dksc0d1s4: Process [fsstress] ran out of disk space |
| # dksc0d1s4: Process [fsstress] ran out of disk space |
