I believe ZFS is causing a panic whenever I attempt to mount an iso image (SXCR
build 39) that happens to reside on a ZFS file system. The problem is 100%
reproducible. I'm quite new to OpenSolaris, so I may be incorrect in saying
it's ZFS' fault. Also, let me know if you need any additional information or
debug output to help diagnose things.
Config:
[b]bash-3.00# uname -a
SunOS mathrock-opensolaris 5.11 opensol-20060605 i86pc i386 i86pc[/b]
Scenario:
[b]bash-3.00# mount -F hsfs -o ro `lofiadm -a
/data/OS/Solaris/sol-nv-b39-x86-dvd.iso` /tmp/test[/b]
After typing that the system hangs, the network drops, panics, and reboots.
"/data" is a ZFS file system built on a raidz pool of 3 disks.
[b]bash-3.00# zpool status sata
pool: sata
state: ONLINE
scrub: none requested
config:
