| # FS QA Test 004 |
| # |
| # Tests a bug fix found in cephfs quotas handling. Here's a simplified testcase |
| # that *should* fail: |
| # |
| # mkdir files limit |
| # truncate files/file -s 10G |
| # setfattr limit -n ceph.quota.max_bytes -v 1048576 |
| # mv files limit/ |
| # |
| # Because we're creating a new file and truncating it, we have Fx caps and thus |
| # the truncate operation will be cached. This prevents the MDSs from updating |
| # the quota realms and thus the client will allow the above rename(2) to happen. |
| # |
| # The bug resulted in dropping support for cross quota-realms renames, reverting |
| # kernel commit dffdcd71458e ("ceph: allow rename operation under different |
| # quota realms"). |
| # |
| # So, the above test will now fail with a -EXDEV or, in the future (when we have |
| # a proper fix), with -EDQUOT. |
| # |
| # This bug was tracker here: |
| # |
| # https://tracker.ceph.com/issues/48203 |
