You can compare OpenIndiana oi_148 (and oi148a with IllumOS) and publish 
comparisons.
I think site: Phoronix.com already did comparisons with ZFS under 
several platforms and other (Linux) file systems without sweat.

OpenIndiana and others (i.e. Benunix) are distributions that actively
support full desktop workstations based on the Illumos base.

It is true, that the storage server application is a popular one and so has
supporters both commercially and others. ZFS is amazing and quite rightly it
stands out, it works even better when used with zones, crossbow, dtrace,
etc. and so its obvious to see what it's a focus and often seems the only
priority. 

However is isn't the only interest, by a long shot.

The SFE package repositories has many packages available to install for when
the binary packaging aren't up to date. OpenIndiana is hard at work trying
to build bigger binary repositories with more apps and newer versions.
A simple pkg install APPLICATION is the aim for the majority of main
applications.

Is it not moving fast enough, or missing the packages you need?
Well that's the beauty of Open Source, we welcome and have systems to help
newcomers add and update the packages and applications they want, so we all
benefit. 

Ultimately I'd (and I'm sure many would) like to have a level of binary
repositories similar to Debian, with stable and faster changing place repos
and support for many different applications, however that requires a lot of
work and manpower.

Honestly (and I say this from purely personal preferences and bias, not 
any official statement), I see the long-term future of Solaris (and 
IllumOS-based distros) as the new engine for appliances, supplanting 
Linux and the *BSDs in that space.


For a lot of reasons, Solaris has a long list of very superior 
functionality that make is very appealing for appliance makers.  Right 
now, we see that in two areas:  ZFS for storage, and high scaleability 
for DBs (the various Oracle ExaData stuff).   I'm expecting to see a 
whole raft of things start to show up - JVM container systems (Run Your 
App Server in SUPERMAN MODE! ), online backup devices, firewall 
appliances, spam and mail filter systems, intrusion detection systems, 
maybe even software routers, etc...


It's here that I think Solaris' strengths can beat its competitors, and 
where its weaknesses aren't significant.


Sadly, I think Solaris' future as a general-purpose OS is likely finished.

Of course, that's just my reading of the tea leaves...

It has been a long time since I thought that Solaris made a good
Workstation, SunRays not withstanding. The JDS spin of Gnome was an
attempt to get back into the Workstation space, but IMHO was not
really a player. Solaris' strengths have been on the server side and
some of the very serious innovation in Solaris 10 really solidified
that position (ZFS, dtrace, SMF, FMD, etc.). With this as the starting
point, it is easy to see how packaging Solaris into an appliance is
appealing.

While I am mostly a Solaris admin, my desktop runs Linux and has
for over 5 years. The strength of the desktop tools consistently
available on Linux as part of the distribution was what converted me
over. Back in 1996 I had a dual CPU SPARC20 running
OpenLook/OpenWindows as my desktop and it was fantastic, but times
change.

[zfs-discuss] Any use for extra drives?

2011-03-23 Thread Nomen Nescio
Hi ladies and gents, I've got a new Solaris 10 development box with ZFS
mirror root using 500G drives. I've got several extra 320G drives and I'm
wondering if there's any way I can use these to good advantage in this
box. I've got enough storage for my needs with the 500G pool. At this point
I would be looking for a way to speed things up if possible or add
redundancy if necessary but I understand I can't use these smaller drives to
stripe the root pool, so what would you suggest? Thanks.

[zfs-discuss] ZFS and standard backup programs

2011-03-23 Thread Linder, Doug
OK, I know this is only tangentially related to ZFS, but we're desperate and I 
thought someone might have a clue or idea of what kind of thing to look for.  
Also, this issue is holding up widespread adoption of ZFS at our shop.  It's 
making the powers-that-be balk a little - understandably.  If we can't back up 
stuff on ZFS, we can't really use it.

We have a ZFS filesystem that's guarded by the Vormetric encryption product to 
prevent unauthorized users from reading it.  Our backup software, HP's Data 
Protector, refuses to back up this dataset even though it runs as a user with 
privileges to read the files.  When we guard a ZFS dataset with Vormetric, we 
get the alerts below in HP DP and the data is not backed up.  Any suggestions 
at all are welcome.

Note that, yes - files in similarly protected directories on UFS file systems 
do get backed up correctly.  So it has *something* to do with ZFS.

Kick off a back up of the dataset/s in question, and run truss(1) on the
processes in question to see what they're doing. Dtrace(1M) would be
another option, and you could limit the tracing to only file system
operations (as opposed to every system call).

The first one looks like it's tripping up on the fact that each dataset is
treated as a different mount point / file system (in the df(1M) sense).
You may have to specify each data set independently.

For the second, it may be that the software is calling acl(2) or
acl_get(3SEC) and it doesn't support the new NFSv4-style structures that
are coming back.

Even though the pool is at 98% utilization, it's usually not a problem
if the production server is sending datasets which hold VM machines.
Here we seem to be clearly maxing out on IOPS of the disks in the
raidz1-2 vdev. It seems logical to go back to mirrors for this kind of
workload (lots of small files, nothing sequential).

What I cannot explain is why c4t1d0 is doings lots of reads, besides
the expected reads. It seems to be holding back the resilver while I
would expect only c4t9d0 and c4t10d0 should be reading. I do not
understand the ZFS internals that are making this happen. Can anyone
explain that? The server is doing nothing but the resilver (not even
receiving new zfs send's).

By the way, since this is OpenSolaris 2009.6, there is a nasty bug
that if I enable fmd, it'll record billions of checksums errors until
the disk is full (so I've had to disable it while resilvering is
happening).
