Description Jason Tibbitts 1999-11-07 21:17:19 UTC
I ran into some issues when installing 6.1 on a machine with
a DAC960-based RAID array.  Using Disk Druid I created a
number of partitions on /dev/rd/c0d0 (/, /boot, /var, /usr,
/usr/local, /home and a swap partition).  Disk Druid made
one primary partition, put /boot on it, and put the rest
inside an extended partition starting at c0d0p5.  More
specifically, / was on c0d0p9.

Unfortunately the minor device allocations for the DAC960
drivers only allow seven partitions per virtual disk, so /
could not even be mounted and the install failed with an
error about not having space on / (as it was trying to do
the install into the ramdisk).

Running in expert mode, using fdisk to avoid wasting two
primary partitions and paring down the list by one was
enough to get everything to fit.

It would be nice if Disk Driud didn't waste those primary
partitions.  It would also be nice if the DAC960 driver
didn't have such a tiny partition limit, but that's not
something I expect you can fix.

This issue has been assigned to a developer for further action.

We've made some changes to disk druid to use primary partitions slightly
differently than in the past, but it does not know about the limitations
of the RAID array you have. I would recommend using fdisk since it allows
you inifinte flexibility (at the expense of user friendliness admittedly).
