gpart mbr scheme

2009-10-10 Thread Anselm Strauss

Hi,

I'm trying to partition a compact flash card with gpart. When I want  
to create a new MBR scheme it always complains:


- gpart create -s mbr da0
gpart: scheme 'mbr': Invalid argument

The GPT scheme works fine:

- gpart create -s gpt da0
da0 created
- gpart show da0
= 34  8027645  da0  GPT  (3.8G)
   34  8027645   - free -  (3.8G)
- gpart destroy da0
da0 destroyed

The kernel driver seems to be loaded:

- kldstat -v | grep mbr
278 g_mbr
277 g_mbrext

Does gpart in 7.2 not support MBR partitioning?


Cheers,
Anselm

documentation for gpart(8)/GPT?

2009-07-28 Thread Robert Huff
	Is there anything - official, or unofficial but reliable - about 
working with gpart/GPT?	I've read the man page, and am still a little 
wobbly.

Have a look at http://eis.bris.ac.uk/~mexas/geom-mirror.html
This is a proposed addition to the handbook. There is a gpart
example.

By the way, I'd welcome any feedback on this modified section.

First iussue: the Next link in the upper right hand corner doesn't 
work.
	I am most interested in creating partitions generic )non-RAID) UFS(2) 
filesystems.

Very close to what I want.

`gpart show` and secondary GPT header

2009-06-12 Thread Alexander Best
i have a question about gpart. when id do `gpart show ad0` i get the following
output:

=   34  488394988  ad0  GPT  (233G)
 34   209714861  freebsd-swap  (10G)
   20971520  4674235022  freebsd-ufs  (223G)

which is just what i want. however i'm a bit curious about the GPT header.
only the primary header from 0 - 33 is being shown. what about the
secondary/backup GPT header. is it present and just now shown by gpart or
doesn't it exist at all?

because in 7-STABLE e.g. `pt show ad0` also displays the secondary GPT header
at the end of the disk.

cheers.

...oh...and i'm running HEAD (r193846M). ;)
