Hello all,
Isn't a large block size a simple case of prefetching? In other words,
if we possessed an intelligent prefetch implementation, would there
still be a need for large block sizes? (Thinking aloud)
:)

I have solaris 10 U2 and I have raidz partition setup on 5 disks, I just added a
new disk and was wondering, can I add another disk to raidz? I was able to add
it to a pool but I do not think it added it to zpool.
[13:38:41] /root zpool status -v mypool2
pool: mypool2
state: ONLINE
Is it possible to construct a RAID-10 array with ZFS? I've read through the ZFS
documentation, and it appears that the only way to create a RAID-10 array would
be to create two mirrored (RAID-1) emulated volumes in ZFS and combine those to
create the outer RAID-0 volume.
Am I approaching this
yeah disks need to be identical but why do you need to do prtvtoc and fmthard
to duplicate the disk label (before the dd), I thought that dd would take care
of all of that... whenever I used dd I used it on slice 2 and I never had to do
prtvtoc and fmthard... Juts make sure disks are identical
you don't really need to do the prtvtoc and fmthard with the old Sun
labels if you start at cylinder 0 since you're doing a bit - bit
copy with dd .. but, keep in mind:
- The Sun VTOC is the first 512B and s2 *typically* should start at
cylinder 0 (unless it's been redefined .. check!)
-
After some experimentation, it seems something like the following command would
create a RAID-10 equivalent:
zpool create tank mirror [i]disk1[/i] [i]disk2[/i] mirror [i]disk3[/i]
[i]disk4[/i]

Reads? Maybe. Writes are an other matter. Namely the overhead associated
with turning a large write into a lot of small writes. (Checksums for
example.)

That is not what I wrote.
