** Description changed: + Impact + ====== + When making multiple copies of a V5 filesystem with xfs_copy those copies will be corrupt due to incorrect UUIDs. + + Test Case + ========= + See the detailed steps to create the test environment in comment #20. + + Regression Potential + ==================== + From the patch "Most of this patch is changing comments and re-ordering tests to match; the functional change is to simply use the *sb rather than the *ag_hdr to identify the proper metadata UUID." So this seems pretty straightforward and given that copy process is currently broken, because the copies are corrupt, this will be an improvement. + + Original Description + ==================== + Problem Description -------------------------------- xfs/073 test fails with Metadata corruption detected on xfs file system.
