Howdee!

Slice10 looks real good.

The only problem I have so far, is on the new sendero;

fsck -p complains that certain partitions are busy.  This I belive to be
incorrect.  There is nothing wrong that is detectable, but the same three
partitions are always busy for fsck -p but will mount -a (or fsck)
perfectly fine from the shell.

I also compiled a SLICEed SMP kernel and that looks correct too.  Managed
to NFS mount all of Nomis on Sendero and cpio the entire machine over
without a hitch.

Here is the configuration, in case you cared:

MB:    P6DNH2 with 2xP6-200
RAM:   384MB
Video: Matrox MGA 2064W graphics accelerator
SCSI:  DPT PM3334UW w/64MB RAM
       DPT PM3334UDW w/64MB RAM

Disks: Iomega Jaz (for testing) - Still have to play with remove-insert
       RAID-1 for boot device - 4GB usable - Single bus
       RAID-5 for storage - 28GB usable - Single bus shared with RAID-1
       RAID-0 for playing around - 28GB split across 2 busses

There are two DAT drives on the system, one on each bus, as well as a
Yamaha WORM.  They all are doing fine.

I will be adding another RAID-5 array tomorrow and hook up another CPU to
the same pair of busses;  For multi initiator and DLM development.

I have tested the large arrays as both a single 28GB slice/partition and as
a split/fragmented.  They both seem to be doing fine.

The only problem appears to be with fsck.  Given the standard /etc/rc
script it fails miderably with large partitions and/or many filesystems.
It needs the enclosed patch to work.

If fsck cannot be fixed to acomodate such a large collection of large
disks, I'll be happy to submit a patch the /etc/rc that works.  It is a bit
slower than the current one but works.

Thanx for the help and the functionality.

Simon
