This is what I've done, but am still a bit stuck, as it doesn't quite work!

Hello list,
Before we started changing to ZFS bootfs, we used DiskSuite mirrored ufs
boot.
Very often, if we needed to grow a cluster by another machine or two, we
would simply clone a running live server. Generally the procedure for
this would be;
1 detach the "2nd" HDD, metaclear, and d
I think a picture is emerging that if you have enough RAM, the
ARC is working very well. Which means that the ARC management
is suspect.
I propose the hypothesis that ARC misses are not prefetched. The
first time through, prefetching works. For the second pass, ARC
misses are not prefetched, so

Hi!
I'm trying to replicate two thumpers with AVS, and I was wondering, is it
possible to put bitmaps on ZVOL-s on rpool mirror? It seems to me a much
simpler solution then to partition every disk with slice 0 as data and slice 1
as bitmap?

Ross,
Please refresh your test script from the source. The current script
tells cpio to use 128k blocks and mentions the proper command in its
