Neil Brown b7a708af6f Fixed UUID printing in "--detail --brief" for version1 metadata. 2006-11-09 16:28:27 +11:00
Neil Brown 60e1bc1a33 Fixed problems that could cause infinitel loop with auto assemble. 
If an auto-assembly attempt failes because the array cannot be
opened or because the array has already been created, then we
get into an infinite loop.

Goswin Brederlow 2790ffe38a Document that the default metadata version can be overridden in config file. 
From: Goswin Brederlow <brederlo@informatik.uni-tuebingen.de>

This is already mentioned in the config documentation, but not in the
place when the normal default is mentioned.

Luca Berra 435d4ebb2e Mdassemble improvements 
From: Luca Berra <bluca@comedia.it>

- Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele
  stacked arrays.
- Allow mdassemble, when run a second time, to mark all arrays as writable.
  This is useful if they are started read-only as is best at boot-time.

 code was ever in there)

Neil Brown 7eae7080e2 Work around bug in --add handling for version-1 superblocks 
In 2.6.17 (and prior), the dev_number is ignored when a device
is added to an active array.  Rather the first free number is used.
So we work around this by making sure we use the first free
number for dev_number.
