Hi Ivan,
there's no firm date for this yet, though the install team are
working *really* hard at getting this to happen as soon as humanly
possible.

After replacing a bad disk and waiting for the resilver to complete, I
started a scrub of the pool. Currently, I have the pool mounted
readonly, yet almost a quarter of the I/O is writes to the new disk.
In fact, it looks like there are so many checksum errors, that zpool
doesn't even list them p

yes it can be turned on. But I don't know if ZFS would then know about it.
I'd still feel more comfortably with it being turned off unless ZFS itself
does it.

Do you have data on this? The reconstruction should be relatively cheap
especially when compared with the initial disk access.

I can get USED in bytes of file systems in zfs pool but i do not know how to
get USED in bytes for pools.
I need such exact value of used size on pool to get system overheads while
using snapshots. Any information about this?
