Agree. This is a better solution because some configurable parameters
are hidden from zfs get all

It basically says that 'zfs send' gets a new '-b' option so send back
properties, and 'zfs recv' gets a '-o' and '-x' option to allow
explicit set/ignore of properties in the stream. It also adds a '-r'
option for 'zfs set'.
If/when
The reason for wanting raidz was to have some redundancy in the backup without
the big hit on space that duplicating the data would have.
The other issue is the switching process. More likely to have screwups if every
week I, or someone else when I'm out, have to break and reset 24 mirrors
How's that working for you? Seems like it would be as straightforward as I was
thinking - only possible.

Thanks Cindy - I've been looking for an admin guide!
I'll play with the split command - sounds interesting.

Yeah, that's starting to sound like a fairly simple but equally robust
solution. That may be the final solution. Thanks!

True! I don't need the same level of redundancy on the backup as the primary.

Is it possible to mirror two raidz vdevs? Like a RAID50 basically.

Hi,
Is it possible to mirror two raidz vdevs? Like a RAID50 basically.
Raid 50 is striped...
basically:
zpool create tank raidz c0t0d0 c0t0d1 c0t0d2 raidz c1t0d0 c1t0d1 c0t0d2
Other than that, I believe it is not possible to create a mirrored
pool from raidz vdevs

This config is not supported by zfs. It should be possible to do
though if you are really serious about it. You can create
Ah. Thanks! I should have said RAID51 - a mirror of RAID5 elements.
Thanks for the info. Bummer that it can't be done.

RAID50 is not a mirror
I wanted to test it as a backup solution. Maybe that's crazy in itself but I
want to try it.
Basically, once a week detach the 'backup' pool from the mirror, replace the
drives, add the new raidz to the mirror and let it resilver and sit for a week.

You might look at the zpool split feature, where you can
split off the disks from a mirrored pool to create an identical
pool, described here:

though if you are really serious about it. You can create two zfs
zvols (volumes) which are hopefully in two different raidz-based zfs
pools, and then create a new zfs pool using those two devices. The
end result would be three zfs pools. It is probably not a wise

If that's the case why not create a second pool called 'backup' and
'zfs send' periodically to the backup pool?

This is what I do.
