I created the pool by using: zpool create ZPOOL_SAS_1234 raidz c7t0d0 c7t1d0 c7t2d0 c7t3d0
However now that you mentioned the lack of redundancy I see where is the problem. I guess it will then remain a mystery how did this happen, since I'm very careful when engaging the commands and I'm sure that I didn't miss the "raidz" parameter. Could this by chance have been caused by some sort of bug that existed in the previous releases of OpenSolaris ? I'm using the OS on my machine since around B11X (can't remember exactly but maybe 119) and I kept upgrading it constantly till now. Thanks for the quick response and your help. p.s. I guess I was too lazy to check the pool itself. No kidding I should have started with the simple checks first :) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
