I am using ZFS as the backing store for an iscsi target running a virtual
machine.
I am looking at using 8K block size on the zfs volume.
I was looking at the comstar iscsi settings and there is also a blk size
configuration, which defaults as 512 bytes. That would make me believe that

Agreed, however:
#1 Shorter values of "forever" (like, say, "daily") may still be useful.

Hello,
I see strange behaviour when qualifying disk drives for ZFS. The tests I want
to run should make sure that the drives honour the cache flush command. For
this I do the following:
1) Create singe disk pools (only one disk in the pool)
2) Perorm I/O on the pools
This is done via SQLIte an

Okay, so after some test with dedup on snv_134. I decided we can not to use
dedup feature for the time being.
While unable to destroy a dedupped file system. I decided to migrate the file
system to another pool then destroy the pool. (see below)

This is the case with most OSes now. Swap out stuff early, perhaps
keep it in RAM and swap at the same time, and the kernel can choose
what to do later. In Linux you can set it in

I'm answering my own question, having just decided to try it. Yes, anything you
want to persist beyond reboot with EON that's not in the zfs pools has to have
an image update done before shutdown.

Dagnabbit. I'm glad you told me this, but I would have thought that running a
