Hi
Some developers here said a long time ago that someone should show
the code for LZO compression support for ZFS before talking about the
next step. I made that code with a friend and we also made a little
benchmark to give a first impression:

Isn't the main problem license, LZO being GPL, while zfs CDDL?

I would think that you'd be fairly confident of the integrity of the data
since everything would be checksummed.

Yup, that one was down to a known (and fixed) bug though, so it isn't the
normal story of ZFS problems.

Thanks for the informative analysis!
Just wondering - are there better candidates out there than even LZO
for this purpose?

Hi,
I've encountered this bug:
http://www.opensolaris.org/jive/thread.jspa?threadID=108316tstart=30
and to obviate to the problem I'm using legacy mounts.
Now the system boot without problems, but nfs server doesn't start because
couldn't find any share.
So I've disabled nfs with zfs set
I did see this, Thanks.

The only problem I see, is data set size. Let me explain (and please correct
if I'm wrong).
ZFS basically compresses 2 things -- metadata and data. And data is at most
128k chunk.
Each chunk is individually compressed, not the whole file.
This should affect dictionary size for the lzo

Hello!
I have a clean installation of Solaris Express Community Edition Build 119.
I created a zpool consisting of a mirror of two iSCSI disks. The new pool is
empty - no files or filesystems yet.
After some time I might have lost the connection to the iSCSI devices resulting
in a crashed

Hi there,

Trouble is, the SMB share would disappear from the network at least
once a day, and when it happens, I have to reboot OpenSolaris

tamp is perhaps another interesting candidate. But Tim is in a better
position to say where it is heading.
