what's eating the space?



Hi all,

I just set up a new system, and among others, the first partition on
each of the three disks is a 32 Mb primary partition to be used in
a RAID1 configuration (2 active, 1 spare) for /boot:

  /dev/sda1   *   1    4       32098+  fd  Linux raid autodetect

The RAID volume also appears to be 32Mb in size:

  # dd if=/dev/md0 bs=1M > /dev/null                              [63]
  31+1 records in
  31+1 records out
  32768000 bytes transferred in 0.033353 seconds (982457689 bytes/sec)

So I made an XFS filesystem on it and am now surprised to find only
12 Mb of free space. Well, not really surprised, but it's an
inconvenience. Am I right in assuming that XFS just claims 20Mb of
the filesystem for itself?

Now I will have to repartition... Thanks to the three disks and
RAID, I should be able to do this on the running system itself. :)

Thanks for any comments...
