New/Changes/Fixes:
- removed iscsitgd and replaced it with COMSTAR (iscsit, stmf)
- added SUNWhd to image vs being in the binary kit.
- added rsync to image vs being in the binary kit.
- added nge, yge and yukonx drivers.
- added (/etc/inet/hosts, /etc/default/init) to /mnt/eon0/.backup (TIMEZONE and hostname change fix)
- fixed typo entry /mnt/eon0/.exec zpool -a to zpool import -a
- eon rebooting at grub(since snv_122) in ESXi, Fusion and various versions of VMware workstation. This is related to bug 6820576. Workaround, at grub press e and add on the end of the kernel line "-B disable-pcieb=true"

Hey there!!

I figured I would give this version a go and so far things seem to be working pretty good. EON 64-bit x86 Samba is the version of choice. With a two drive zpool (RAID 0) I am seeing file transfer speeds of around 80-90 MB/sec. I did a three drive zpool and speeds were right at 95-100 MB/sec which is the max my client can do with a single drive. With a single drive zpool I still am seeing the file transfers stall, then blast along, then stall when writing to the server... same as before. Also see this behavior with a 3 drive mirror. I am pretty sure it has to do with how fast the OS is able to write to the disk. Using dd I have measured actual write speed for 1000 MB to a 3 drive mirror at about 58 MB/sec. Diskspeed.sh shows raw speed at 100 MB/sec for all three drives. Probably just the nature of the beast with ZFS and writes.

Just to note... in my previous testing I always had problems getting higher than around 60 MB/sec for reads. My tests so far with this version are getting much better read speeds. Around 90 MB/sec with a 2 drive zpool. Beyond this I was quite impressed with how well a 2 drive zpool (RAID 0) could handle multiple streams. I had one computer here copying a file to the server and one computer reading a file from the server. Each file transfer was able to settle in around 50 MB/sec. I haven't done extensive testing with this on other platforms but from what I recall similar experiments with a different OS were more like 30 MB/sec and 40 MB/sec.

I am probably going to do some more testing but wanted to give you some feedback.

One weird thing I noticed though was that my zpool is not being imported when I reboot the system. I have to manually import it. The previous EON versions I used automatically imported zpools from what I recall.

Great feedback

Good to here from you 00Roush,

Thanks for the feedback. As always great info. The intermittent flushing is part by design and could be part because you've reached buffering limits + max speed of the pool (as you stated).
Sometimes you can see it, when it is a network transfer by seeing if the network limit is reached. So you would watch the transfer in one window and the zpool disk i/o in another
To see network transfer http://sites.google.com/site/eonstorage/faq#TOC-How-can-I-see-the-amount-of-network
and zpool I/O
zpool iostat -v 1

The hard thing is determining which limit is being hit. I'd be curious to see what you get with the CIFS image as it has matured quite a bit.

The pool not auto importing is because they deprecated the zvolinit call. The fix is to uncomment the following in /mnt/eon0/.exec
/usr/sbin/zpool import -a

Let me know if you have any questions Roush. The next release may have de-duplication so keep checking back and thanks again for the update.
