Greetings,
I have Sun Fire 4600 running Solaris 10, running Sun Cluster 3.2.
SunOS hubdb004 5.10 Generic_120012-14 i86pc i386 i86pc
We ran into some space issues in /usr today, so as a quick fix, I created a
slice (c5t0d0s12) with about 25GB of disk in order to create some zfs
filesystems with mount points inside /usr...
# zpool status
pool: tank01
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
tank01 ONLINE 0 0 0
c5t0d0s12 ONLINE 0 0 0
errors: No known data errors
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
tank01 251M 24.2G 24.5K /tank01
tank01/openwin 40.2M 24.2G 40.2M /usr/openwin
tank01/usrlocal 210M 24.2G 210M /usr/local
All seems good...except when an unprivileged user runs df -k or df -h, df
core dumps when it hits the zpool. Running df as root does not produce the
coredump. Both root and me run /usr/sbin/df. When me runs df alone it
exits normally.

Segmentation Fault (core dumped)
As root... the same as above but with the following instead of the Seg Fault
tank01 24G 24K 24G 1% /tank01
tank01/openwin 24G 40M 24G 1% /usr/openwin
tank01/usrlocal 24G 210M 24G 1% /usr/local
/export/home/me
996M 227M 709M 25% /home/me
This is slighly problematic as we feel it's improper to run things like
monitors as the root user.
I have been searching Google, SunSolve and OpenSolaris, but either my search
terms are poor (most likely) or this has never been reported.
Any thoughts or suggestions would be most appreciated. I much prefer the
use of zfs for this purpose over creating a UFS filesystem and using sym
links. from /usr/<whatever> to the UFS filesystem.
