md: print errno in super_written

md: register new md sysfs file 'uuid' read-only

2020-08-03T06:03:51+00:00

Report the UUID of the MD array in the following format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx This is useful if you don't want to wait for udev to identify array. And it is also easy for script to monitor it with the format. Signed-off-by: Sebastian Parschauer [Guoqing: mention the change in md.rst] Signed-off-by: Guoqing Jiang Signed-off-by: Song Liu

md: fix max sectors calculation for super 1.0

2020-08-03T06:03:51+00:00

To grow size of super 1.0 raid array, it is necessary to check the device max usable size. Now it uses rdev->sectors for max usable size. If one disk is 500G and the raid device only uses the 100GB of this disk. rdev->sectors can't tell the real max usable size. The max usable size should be dev_size-(superblock_size+bitmap_size+badblock_size). Also, remove unnecessary sb_start update in super_1_rdev_size_change().
