[OpenIndiana-discuss] zpool export import alternate cachefile

[Randy S]

Sir,

Thank you very much for your speedy reply!

I was under the impression that by using the cachefile (as explained on different sites) the import should be faster. That's why I kept trying with a copy of the original cachefile.

High regards,

Randy
