We need to create disk images for Lustre 2.10.0 and 2.12.0 for conf-sanity test_32 upgrade regression testing, similar to the existing lustre/tests/disk*.tar.bz2 files.
These new test filesystems should include files using the new features for those releases, and tests that verify they are working properly:
- PFL file layouts
- project quotas
- FLR mirrored files
- DoM files on the MDTs
Also, some of the files need to be striped over multiple OSTs (e.g. "lfs setstripe -c 2"), but store data on only a single object (i.e. size = 4KB). This relates to an LFSCK issue that I saw with filter_fid and would be good to test.
