For my Google Summer of Code project for OpenSolaris, my job is to think about

D'oh! Thanks for the tip.
I was testing the Solaris Express version, which is working fine, here:
http://docs.sun.com/app/docs/doc/819-2252/6n4i8rtv2?a=view
If you're working with OpenSolaris features, then the Solaris Express
docs will more closely correlate than the Solaris 10 man pages.

Wouldn't that be:
5 seconds per write = 86400/5 = 17280 writes per day
256 rotated locations for 17280/256 = 67 writes per location per day
Resulting in (10/67) ~1492 days or 4.08 years before failure?
That's still a long time, but it's not 100 years.

Hi Ricardo,
I just tested most of the links from the zones.5 man page on

There are still a few problems in docs.sun.com.
If you go to the zones(5) manpage and click on any link, it says "Error: The

I think there was also a link in one of the zones commands or libc functions
that pointed to the wrong manpage, but I don't rememb

Perhaps this discussion wasn't quite clear. ZFS supports all characters (with
the standard UNIX exceptions of null and forward slash) in filenames.
It's only the names of ZFS data structures, such as file systems, pools, and
snapshots, which are restricted. For instance, @ is used as a separat
Hi
It is my understanding that zfs will be available to pre S10 update 2
customers via patches, ie customers on FCS could install the necessary
zfs patches and thereby start using zfs.
But there seems to be confusion in regards to whether this is supported
or not.

Do you have any disk based swap ?
One best practice we probably will be coming out with is to
configure at least physmem of swap with ZFS (at least as of
this release).
The partly hung system could be this :
