Hello zfs-discuss,
I had a zfs file system with recordsize=8k and a couple of large
files. While doing zfs send | zfs recv I noticed it's doing
about 1500 IOPS but with block size 8K so total throughput
wasn't impressive.
So I stopped it and tried to cp files from

It may become more relevant with flash memory as a storage medium.
Would it be worth considering bring it back as part of zdb rather than
part of the core zio layer ?

I'm not convinced that single bit flips are the common failure mode for disks.
I think the original suggestion might be for bad RAM more than bad disks. Just
about every home computer does not have ECC RAM, so as ZFS transitions from
enterprise to home, this (optional) feature sounds very

How common would be single on-disk bit flips in 128K blocks?
Most enterprise

Hi,
New user question. In ZFS (solaris 10) are we able to evacuate a disk
if I later decide to remove it from a ZFS pool. I know the answer use
to be no but I'm not sure if that has changed or will change.

have enough ECC to correct at least 8 bytes per block.
and for consumer rather than enterprise class disks ?
You are assuming that

Hey, Bob
My perspective on Big reasons for it *to* be integrated would be:
- It's tested - By the folks charged with making ZFS good
- It's kept in sync with the differing Zpool versions
- It's documented
- When the system *is* patched, any changes the patch brings are
synced with the
