Re: [zfs-discuss] rpool on ssd. endurance question.
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. I'd be happy to, exactly what commands shall I run? 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 . ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
