array.size is 32bits and counts K. So for arrays with
more than 4Terrabytes, it can overflow.
The correct number can be read from sysfs, but there are still
a few places that use array.size and risk truncation. What is worse.
they compare a number of kilobytes with a number of sectors !!
So use get_component_size() to read the sysfs information, and be
more consistent about units.

We used to use the major/minor numbers, but that isn't sufficient
any more, so pass the fd, and possibly check 'text' version.

It is now in the 'supertype'
|
|
|
|
| |
The 'superblock' will be moved into this structure soon.
|
|
|
|
|
|
| |
As the metadata handler allocates the superblock, it should free it
too. DDF will have a more complex 'superblock' which needs more complex
freeing.

This patch fixes a NULL pointer dereference in Detail.c when running
'mdadm --detail --export' on a device with non-persistent super blocks.
|
|
|
|
|
| |
'avail' is undefined if '--export', so make sure we don't try to use
it.
|
|
|
|
| |
Missing devices as well as failed devices cause an error.

udev likes to get information about a device as key=value pairs so it
can create disk/by-id links etc. So add --export flag which causes
the output of --detail to easily parsable.

Instead of opencoding the same thing everywhere.

because it only shows how much of each device is actually used, not
how big they are.

.. this causes silly warnings.
Unfortuantely there are 2.6 kernels which will still produce
warnings. We cannot reliable detect those.

This means that "-Ds" lists arrays in an approprate order

i.e. allow '--help' to be first and still give
context sensitive help.
Also don't print truncated device-size of very large arrays.

As the device list isn't stable, recording it should be avoided.
The device= list is still available if --verbose is given (once).

This allows for larger device number if glibc supports
it (requires 2.3.3).
Also fail before creating larger device number if glibc
support isn't present.
