OpenZFS 6865 - want zfs-tests cases for zpool labelclear command
Authored by: Yuri Pankov <[email protected]> Reviewed by: Matthew Ahrens <[email protected]> Reviewed by: John Kennedy <[email protected]> Approved by: Robert Mustacchi <[email protected]> Reviewed-by: loli10K <[email protected]> Ported-by: Brian Behlendorf <[email protected]> Porting Notes: - Updated 'zpool labelclear' and 'zdb -l' such that they attempt to find a vdev given solely its short name. This behavior is consistent with the upstream OpenZFS code and the test cases depend on it. The actual implementation differs slightly due to device naming conventions on Linux. - auto_online_001_pos, auto_replace_001_pos and add-o_ashift test cases updated to expect failure when no label exists. - read_efi_label() and zpool_label_disk_check() are read-only operations and should use O_RDONLY at open time to enforce this. - zpool_label_disk() and zpool_relabel_disk() write the partition information using O_DIRECT an fsync() and page cache invalidation to ensure a consistent view of the device. - dump_label() in zdb should invalidate the page cache in order to get the authoritative label from disk.
