Very good point bill - just ran this test and started to get the numbers I was

I don't have an answer to this question, but I can say, I've seen a similar
surprising result. I ran iozone on various raid configurations of spindle

50% to 200% faster than the next best competitor in each category. . I d

Hi Tim,
I'm not sure why your spare isn't kicking in, but you could manually
replace the failed disk with the spare like this:

If you want to run with the spare for awhile, then you can also detach

I think this is a great idea and may be the only reasonable way to backup tera
bytes of data with low cost disks. And the idea is quite popular, just google

Hi Tony,
Good questions...
Yes, you can assign a spare disk to multiple pools on the same system,
but not shared across systems.
The problem with sharing a spare disk with a root pool is that if the
spare kicks in, a boot block is not automatically applied. The
differences in the labels is prob

The problem here and Richard described it well is that the ctdp* devices
