The big question is whether they are worth the effort. Spares solve a

problem and only impact availability in an indirect manner. For single-parity
solutions, spares can make a big difference in MTTDL, but have almost no impact

One use-case would be for Home-NAS setups where multimedia (video

Hello all,
I understand that relatively high fragmentation is inherent
to ZFS due to its COW and possible intermixing of metadata
and data blocks (of which metadata path blocks are likely
to expire and get freed relatively quickly).
I believe it was sometimes implied on this list that such

Dear list,

Hello all,
For smaller systems such as laptops or low-end servers,
which can house 1-2 disks, would it make sense to dedicate
a 2-4Gb slice to the ZIL for the data pool, separate from
rpool? Example layout (single-disk or mirrored):
s0 - 16Gb - rpool
s1 - 4Gb - data-zil
s3 - *Gb - data pool
Hello, Jesus,
I have transitioned a number of systems roughly by the
same procedure as you've outlined. Sadly, my notes are
not in English so they wouldn't be of much help directly;
but I can report that I had success with similar "in-place"
manual transitions from mirrored SVM (pre-solaris 10u
