I’d like to report the ZFS related crash/bug described below. How do I go about
reporting the crash and what additional information is needed?
I’m using my own very simple test app that creates numerous directories and
files of randomly generated data. I have run the test app on two machines, both
64 bit.
OpenSolaris crashes a few minutes after starting my test app. The crash has
occurred on both machines. On Machine 1, the fault occurs in the SCSI driver
when invoked from ZFS. On Machine 2, the fault occurs in the ATA driver when
invoked from ZFS. The relevant parts of the message logs appear at the end of
this post.
The crash is repeatable when using the ZFS file system. The crash does not
occur when running the test app against a Solaris/UFS file system.
Machine 1:
OpenSolaris Community Edition,
snv_72, no BFU (not DEBUG)
SCSI Drives, Fibre Channel
ZFS Pool is six drive stripe set
Machine 2:
OpenSolaris Community Edition
snv_68 with BFU (kernel has DEBUG enabled)
SATA Drives
ZFS Pool is four RAIDZ sets, two disks in each RAIDZ set
(Please forgive me if I have posted in the wrong place. I am new to ZFS and
this forum. However, this forum appears to be the best place to get good
quality ZFS information. Thanks.)
