Description
In case there ever had been some large files (>2G) on an ufs root filesystem,
you can't fast reboot to such a file system.
# reboot -f /dev/dsk/c29d0s0 /platform/i86pc/kernel/unix -B disable-mouse8042=true -v
reboot: not all drivers have implemented quiesce(9E)
reboot: File too large
reboot: failed to mount /dev/dsk/c29d0s0
reboot: /devices/pci@0,0/pci-ide@1f,1/ide@0/cmdk@0,0:a: kernel name must be unix
# fstyp -v /dev/rdsk/c29d0s0|more

Suggested fix:
==============
I think reboot should mount the ufs file system with option "largefiles"...

Frequency
Always
Regression
No
Steps to Reproduce
On an alternate ufs root files ystem, create some large files, e.g.
with
mount /dev/dsk/c29d0s0 /mnt
mkfile -n 8G /mnt/var/tmp/foobar
umount /mnt
and fast reboot:
reboot -f /dev/dsk/c29d0s0
Expected Result
System reboots (fast reboot).
Actual Result
Fast reboot refuses to mount the alternate root file system, complains with
the error message "reboot: File too large"
Error Message(s)
# reboot -f /dev/dsk/c29d0s0 /platform/i86pc/kernel/unix -B disable-mouse8042=true -v
reboot: not all drivers have implemented quiesce(9E)
reboot: File too large
reboot: failed to mount /dev/dsk/c29d0s0
reboot: /devices/pci@0,0/pci-ide@1f,1/ide@0/cmdk@0,0:a: kernel name must be unix
Test Case
Workaround
Workaround: delete all large files and fsck the ufs file system
Submitter wants to work on bug
Yes
Additional configuration information
SXCE build 95, bfu'ed to current opensolaris (2008-10-2)
Didn't read the bug report fully the first time. Indeed a bug and
should be fixed.
