Neil Brown 142cb9e181 Use sysfs info for metadata version info in Detail and elsewhere. 2007-12-14 20:15:21 +11:00
Neil Brown 7e0f69790c Replace sysarray with mdinfo 
Sure, mdinfo is bigger, but having a uniform structure for lots of things
will make life easier.

Neil Brown 1686dc25ec Find super from fd on an array. 
We used to use the major/minor numbers, but that isn't sufficient
any more, so pass the fd, and possibly check 'text' version.
 2007-12-14 20:14:38 +11:00
Neil Brown 3da92f272d Drop the superblock arg from all metadata methods. 
It is now in the 'supertype'
 2007-12-14 20:14:33 +11:00
Neil Brown 68c7d6d790 Add 'supertype' arg to almost all metadata methods. 
The 'superblock' will be moved into this structure soon.
 2007-12-14 20:14:16 +11:00
Neil Brown df37ffc039 Allow metadata handlers to free their own superblock. 
As the metadata handler allocates the superblock, it should free it
too.  DDF will have a more complex 'superblock' which needs more complex
freeing.

Neil Brown 8e22992203 Remove bogus add_dev definition. 
If nether ftw nor nftw are available, add_dev gets defined twice.
Fix that...
 2007-05-08 17:12:33 +10:00
Neil Brown 8382f19bdc Add new mode: --incremental 
--incremental allows arrays to be assembled one device at a time.
This is expected to be used with udev.

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.
 2006-10-16 15:26:53 +10:00
Neil Brown 0a816ef9fb Don't #include blkpg.h 
Just include the content directly.  It is safer.
 2006-10-16 14:38:13 +10:00
Neil Brown 0430ed4868 Remove partitions from components of an md array 
They do nothing but cause confusion.
 2006-10-13 09:02:35 +10:00
Neil Brown 45e878bba6 Improve ftw handling. 
If not 'ftw' is available, still allow openning of devices by dev number.

More recent version of uclibc support nftw, so add support to check
for that.

Neil Brown e81cdd9f37 Stop map_dev from returning [0:0] 
We sometimes need the NULL when major==minor==0.
So make sure all callers of map_dev can cope with NULL.

Neil Brown eed35d6661 Fix memory leak in monitor mode

Neil Brown 0a416ec307 Make scanning of /dev work even if it is a symlink

/dev itself is a symlink, we want to follow it.
So nftw needs a bit of help.
