| # DESCRIPTION: |
| # |
| # For device removal a file's contents should transfer |
| # completely from one disk to another. That should remain |
| # to be the case even if multiple levels of indirection |
| # are introduced as we remove more and more devices. |
| # |
| # STRATEGY: |
| # |
| # 1. We create a file of size 128k and we save its contents |
| # in a local variable. |
| # 2. We set the limit of the maximum copied segment size of |
| # removals to 32k, so during removal our 128k file will |
| # be split to 4 blocks. |
| # 3. We start removing disks and adding them back in a loop. |
| # This way the file is moved around and introduces split |
| # blocks. |
| # 4. The loop itself tests that we don't have any problem |
| # when removing many devices. Within the loop we test |
| # that the files contents remain the same across transfers. |
