Bug#474698: partman-base: Inconsistent output if sector size != 512 bytes

[Ferenc Wagner <wferi@niif.hu>]

Package: partman-base
Severity: normal

Issue the following commands in the D-I shell:

~ # modprobe raid1
~ # mdadm --create /dev/md0 --auto=yes -l1 -n2 /dev/ram0 /dev/ram1
mdadm: array /dev/md0 started.

Then restart partman.  With the text backend it says:

  6. RAID1 device #0 - 8.3 MB Software RAID device     
  7. >      #1   4.2 MB      

Note the inconsistent size report.  This is probably caused by
the ramdisks having sector size of 1024 bytes, as per:

~ # fdisk -l /dev/md0
Note: sector size is 1024 (not 512)

Disk /dev/md0: 8 MB, 8323072 bytes
2 heads, 4 sectors/track, 1016 cylinders
Units = cylinders of 8 * 1024 = 8192 bytes

As persistent storage devices can also have non 512 byte sectors,
this issue can have real impact on the installer, at least by
confusing users.

Regards,
Feri.
