See this thread - it dealt with the same question somehow.

I just tested crypto a little and I have some send/receive specific questions
about it. It would be great if someone could clarify.
Currently ZFS has no background rewriter. However the fact that ZFS applies
most of the properties and tunables (like dedup or compression) on write time
for all n
Hi,
I did a quick test (because I'm curious also). The Hardware was a 3 SATA Disk
RaidZ1.
What I did:
1) Create a pool with NexentaStor 3.0.4 (Pool Version 26, Raidz1 with 3 disks)
2) Disabled all caching (primarycache=none, secondarycache=none) to force media
access
3) Copied and extracted
Actually - I can't read ZFS code, so the next assumtions are more or less based
on brainware - excuse me in advance :)
How does ZFS detect "up to date" zil's ? - with the tnx check of the ueberblock
- right ?
In our corruption case, we had 2 valid ueberblocks at the end and ZFS used
those t

Hello,
actually this is bad news.
I always assumed that the mirror redundancy of zil can also be used to handle
bad blocks on the zil device (just as the main pool self healing does for data
blocks).
I actually dont know how SSD's "die", because of the "wear out" characteristics
I can think
Thanks for the feedback, the idea of it is to give people new to ZFS a
understanding of the terms and mode of operations to avoid common problems
(wide stripe pools etc.). Also agreed that it is a little NexentaStor "tweaked"
:)
I think I have to rework the zil section anyhow because of

Hello list,
while following this list for more then 1 year, I feel that this list was a
great way to get insights into ZFS. Thank you all for contributing.
Over the last month's I was writing a little "whitepaper" trying to consolidate
the knowledge collected here. It has now reached a "beta"
Hello,
we are currently extensivly testing the DDRX1 drive for ZIL and we are going
through all the corner cases.
The headline above all our tests is "do we still need to mirror ZIL" with all
current fixes in ZFS (zfs can recover zil failure, as long as you don't export
the pool, with latest
Actually writes faster then reads are typical fora Copy on Write FC (or Write
Anywhere). I usually describe it like this.
CoW in ZFS works like when you come home after a long day and you ust want to
go to bed. You take of one pice of clothing after another and drop it on the
floor just where
