Hi I currently have 1 ZFS pool (tank) setup with a 4 drive raidz array (c9t4d0 c9t5d0 c7t0d0 c7t1d0) and wanted to add another 4 drive aray. I wasn''t able to figure out what the best practise for that would be. Should the two raidz''s be in the same pool if so what would be the command to do so zpool create tank raidz c9t1d0 c9t2d0 c9t3d0 c9t4d0 or create a separate pool zpool create tank2 raidz c9t1d0 c9t2d0 c9t3d0 c9t4d0 What would be the pro''s and con''s of both? (presuming the first is an actual option). I don''t want to expand the size of the raidz itself so if needed I can pull 4 disks independantly of the rest etc (upgrade them or remove half my storage etc) -- This message posted from opensolaris.org
You can add to an existing pool using zpool add tank raidz disk1 disk2 ... By adding to an existing pool, you don''t need to create new file structures. Your existings structures get addtional space. If you creat a separate pool then you have another pool which you then need to decide how to use. -- This message posted from opensolaris.org
