Small potatoes.. maybe 4 TB total. things are complicated a bit by the fact that my HP xw8600 is not capable of running 3 TB or larger discs. And Is somewhat limited in ports, without some creative cobbling. > Do you own the HDDs already?

[...] Something I'm not clear about. This thread did not cover it.. Is there a big difference between 6 2 disk mirrors in 6 vdevs as compared to 1 vdev of 3 sets of 2disk mirrors. I haven't done the second method. What all does it have going for it over the multiple vdev case? > > "zfs mirror vs raidz": > https://jrs-s.net/2015/02/06/zfs-you-should-use-mirror-vdevs-not-raidz/ > etc. Good reading there, thanks. Although I must admit I probably understood no more than 60 maybe 65 percent. I'm sure its more my shortcoming than the authors. And I'm hope full about that percentage rising. At my age that's always assuming the man with the scythe doesn't burst upon the scene too quickly ... hehe _______________________________________________ openindiana-discuss mailing list openindiana-discuss@openindiana.org https://openindiana.org/mailman/listinfo/openindiana-discuss
