Hello,
My understanding is that people are pretty much SOL if they want to
reconfigure a RAID-Z or RAID-Z2 dataset to, say, a mirror+stripe? That
is, there is no way to do this via a couple of simple commands?
Just say, for the purpose of my general enlightenment and filing away
for if I decide to change my config (as has been recommended), what
would I have to do? Are we talking about copying the data off of the
Solaris box, destroying the dataset and recreating it? You can't have
the same disks setup to do both so that you can sort of plan for a
switch between the two, can you? What other strategies might exist if I
wanted to do this? What sort of pain would be in store for me if I were
to go this route?Vennlige hilsener / Best regards
Currently I know one strategy - copy the data out, destroy the
zpool, create a new zpool, add flags you might want (compression, dedup
etc, although I don't recommend dedup as of 134), restore the data.
Yeah, this is what I was thinking too...
Is there anyway to retain snapshot data this way? I've read about the
ZFS replay/mirror features, but my impression was that this was more so
for a development mirror for testing rather than a reliable backup?
This is the only way I know of that one could do something like this.
Is there some other way to create a solid clone, particularly with a
machine that won't have the same drive configuration?
Best
regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt.
Det er et elementært imperativ for alle pedagoger å unngå eksessiv
anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller
eksisterer adekvate og relevante synonymer på norsk.
