You can set metaslab_gang_bang to (say) 8k to force lots of gang block

I am working on improving some ZFS-related bits in FreeBSD boot chain.
At the moment it seems that the things work mostly fine except for a case where
the boot code needs to read gang blocks. We have some reports from users about
failures, but unfortunately their pools are not available for testi

Hi Lori,

We need to file a CR that allows us to successfully set bootfs to "".
The failure case in this thread was attempting to unset bootfs on
a pool with disks that have EFI labels.

Hi All,
I was just wandering if the issue that affects NFS availability when

More on the issue here:
http://www.mail-archive.com/zfs-discuss@opensolaris.org/msg37288.html
and here:
http://opensolaris.org/jive/thread.
iSCSI writes require a sync to disk for every write. SMB writes get cached in
memory, therefore are much faster.
I am not sure why it is so slow for reads.
Have you tried comstar iSCSI? I have read in these forums that it is faster.

More info:
The crashes go away just by swapping the cpu to a faster/more horsepower cpu.
On one box where the crash consistently happened (2 core slow cpu)
I no longer see the crash after swapping to a quad core.
