I currently have a 7x1.5tb raidz1.
I want to add "phase 2" which is another 7x1.5tb raidz1
Can I add the second phase to the first phase and basically have two
raid5's striped (in raid terms?)
Yes, I probably should upgrade the zpool format too. Currently running
snv_104. Also should upgrade to 110.
If that is possible, would anyone happen to have the simple command
lines to do it quick? I assume I'd be creating another raidz1 and then
somehow growing the "tank" zpool?
Does this make sense, or is this stupid from a performance
perspective? Should I just have two separate zpools? Ideally I would
like to have one massive data storage target. I'd be fine with somehow
changing this into a raidz2 as well, I suppose, since I had planned on
it being another raidz1 anyway.
Or, perhaps I could add tank #2 as a raidz2, and then move all the
data off tank #1, and then add disks individually from tank #1 until I
have all 14 disks in a single raidz2? Performance is not an absolute
must - I can deal with a little bit of overhead.
Thanks in advance.
