So that would mean, if a raidz vdev was required on a system another pool would have to be created with only a mirror vdev in it, to have / on zfs too? Considering the work involved, is raidz / support really worth it? Of course, it's fantastic if you plan to tackle it, but I don't envy you the task :( >> So back to my original question :) >> If one drive in a gconcat gc1 (ad2s2+ad3s2), say ad3 fails, and the broken >> gconcat is completely replaced with a new 500GB drive ad2, is fixing that >> as simple as: >> >> zpool replace tank gc1 ad2 > > That sounds right. Thanks for the info. It's good to know how to fix an array before it's created :) Cheers. -- Mark Powell - UNIX System Administrator - The University of Salford Information Services Division, Clifford Whitworth Building, Salford University, Manchester, M5 4WT, UK.
