I advice to upgrade to newer 2.6.9 kernel - it is much more stable, than this.

No, OpenVZ doesn't use raw partitions.

This is probably an answer - /dev/hda6 is used as a part of LVM group.

Probably, you uppped quota without --save flag. You could check this by `grep
DISKSPACE /etc/vz/conf/102.conf` command.
