[zfs-discuss] rpool on ssd. endurance question.

Hello.

If anybody uses SSD for rpool more than half-year, can you post SMART 
information about HostWrites attribute?

I want to see how SSD wear for system disk purposes.

Hm. I''m experimenting with OpenSolaris in virtual machine now.
Unfortunately I can''t give you exactly how-to.

But i think it is possible to compile Smartmontools 
http://smartmontools.sourceforge.net and get SMART attributes something 
like that:
smartctl -a /dev/rdsk/c0t0d0s0

You need install SUNWgcc package to compile.

Take a look at http://opensolaris.org/jive/thread.jspa?threadID=120402
and http://opensolaris.org/jive/thread.jspa?threadID=124372 .

I tried compiling the smartmontools, using OracleSolarisStudio U1.  I 
can''t get any usable data:




bash-4.0$ pfexec

Next I tried this command to get some info:
