Would this apply to say a SATA SSD used as ZIL? (which we have, a
vertex2ex with supercap)

Repeat until done.
If you have the physical space, you can first put in a new disk, tell it
to replace and then remove the old.

g is an OCZ Vertex2EX (slc&supercap), cache is an Intel 510.
Host has been rebooted 3 times after the pool was created, all the same

So in ZFS, which normally uses 128kB blocks, you can instead store them
100% uniquely into 32 bytes.. A nice 4096x compression rate..
decompression is a bit slower though..

It walks the filesystem/pool trees, so it's not just reading the disk
from track 0 to track 12345, but validates all possible copies.

I've filed an SR pointing at the same bug too, to get momentum.

You should probably ask on some forum/list that's related to illumos..
This is about the ZFS filesystem..

nt writes block 2.. waaiits.. waiits.. server comes up and, server
says OK and writes it to disk.
Now, from the view of the clients, block 0-2 are all OK'd by the server
and no visible errors.
On the server, block 1 never arrived on disk and you've got silent
corruption.
Too bad NFS is re
ng it.
