<div class="gmail_quote">I see maybe you don't really means
raidz1 here. Raidz1 usually refers to "raid5" type vdevs
with at least 3 disks otherwise why pay a penalty for
tracking parity when you can have a mirrored pair. So in
your case you are changing it from one zpool like was laid
out to multiple zpools with each one being 1 mirrored vdev
pair of disks? <br>

I'm really sorry. I've mixed RAID1 with RAIDZ1 that means RAID5.<br>
Sorry for that. Let's talk about 'standard raids': I mean RAID1

<div>So moving from a replicated to a distributed-replicated
model? or a striped-distributed-replicate? what is the
command or layout you would use to get to the model you
are wanting to use?</div>

I'm trying to say that the current Lindsay solution could be better
(AFAIK):<br>
Instead of using a single RAID10, where in case of a "mirror"
failure you have to resync the whole node from the network (24TB in
my example), <br>
a RAID1 solution (with 6 RAID1) is better. In case you loose a
mirror, you have to resync only that mirror from network because.<br>
<br>
Instead of having a plain replicated setup:<br>
<br>
server1:brick1, server2:brick1, server3:brick1<br>
<br>
you'll have:<br>
<br>
server1:brick1, server2:brick1, server3:brick1<br>
server1:brick2, server2:brick2, server3:brick2<br>
server1:brick3, server2:brick3, server3:brick3<br>
<br>
In a distributed replicated setup.<br>
<br>
Each brick is a RAID1 mirror. The aggregation like a RAID-0 is made
by gluster<br>
