Hi,
labelfix http://www.opensolaris.org/jive/thread.jspa?messageID=229969 saved
already a lot of data as it makes dettached devices importable.
A quick test today shows labelfix won't work anymore:
#uname -a
SunOs bigmama 5.11 snv_127 i86pc 386 i86pc Solaris
#./labelfix /dev/rdsk/c0d1s4

As this feature didn't make it into zfs it would be nice to have it

Better to spend time fixing the problem that requires a 'labelfix' as a
workaround, surely. What's causing the need to fix vdev labels?

I don't believe there can be any doubt whether a Flash based SSD (tier1

Charles,
Just like UNIX, there are several ways to drill down on the problem. I
would probably start with a live crash dump (savecore -L) when you see
the problem. Another method would be to grap multiple stats commands
during the problem to see where you can drill down later. I would

It should be noted, the above highlight only applies to Flash based SSD

What is a NVRAM based SSD? It seems to me
What is a NVRAM based SSD?
It is simply an SSD (Solid State Drive) which does not use Flash,
but does use power protected (non-volatile) DRAM, as the primary
storage media.

It's pretty easy to get the alignment right
fdisk uses a default of 63/255/*, which isn't easy
I ran into this issue on my Dell 1850s also. You'll need to go into BIOS,
change the PERC controller mode from RAID to SCSI and reboot. Then when the
system comes back up it will give a warning about switching RAID controller
modes and data loss (Have Backups)!. Then if you boot from
