Description delta407 2004-08-16 21:31:51 UTC 
Attempting to use mdadm-1.2.0 on a 1.5 TB device yields:

------------
# fdisk /dev/sda

Command (m for help): p

Disk /dev/sda: 1498.9 GB, 1498918420480 bytes
255 heads, 63 sectors/track, 182233 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         125     1004031   fd  Linux raid autodetect
/dev/sda2             126      182233  1462782510   fd  Linux raid autodetect

Command (m for help): q

# mdadm --create /dev/md1 -c 64 -l multipath -n 2 /dev/sda2 /dev/sdc2
mdadm: /dev/sda2 is too small: -684701138K
mdadm: /dev/sdc2 is too small: -684701138K
mdadm: create aborted
------------

This appears to be the result of mdadm's use of signed 32-bit integers relating to capacity variables. mdadm-1.6.0 does not suffer from this issue. What is keeping it out of KEYWORDS="x86"?

Is this really a bug then?

If it is resolved in a newer version that's already in portage, feel free to use it.
Comment 2 SpanKY gentoo-dev 2004-08-20 23:19:57 UTC 
1.6.0 moved to stable
