zfs : accidentally adding cache drive to raidz zpool
http://forums.freebsd.org/showthread.php?t=23127
Unfortunately if you have accidentally added a single drive into your raidz pool at the top-level there is no way to just remove the non redundant disk. Your pool is now dependant on this disk.
If you want your pool to be just raidz vdevs, then you will need to backup your data, destroy your pool, create a new pool, and restore your data.
There is no current way to remove a top-level vdev from a pool.

OpenSolaris is Dead

OpenSolaris is Dead.
What follows is an email sent internally to Oracle Solaris Engineers which describes Oracle’s true intentions toward the OpenSolaris project and the future of Oracle Solaris.
This concludes over four years that I (and many other external contributors) have worked on the OpenSolaris project. This is a terrible sendoff for countless hours of work – for quality software which will now ship as an Oracle product that we (the original authors) can no longer obtain on an unrestricted basis.
I can only maintain that the software we worked on was for the betterment of all, not for any one company’s bottom line. This is truly a perversion of the open source spirit.

OpenSolaris users have two choices. They can wait for Oracle to deliver a free Solaris binary called Solaris 11 Express, available with optional support, by the end of the year, ahead of the full release of the next-generation commercial Solaris 11 rev next year or they can hope that Illumos, the new Nextenta-led OpenSolaris fork, turns into something.
opensolaris – increase swap
I found this on opensolaris forums…. A nice way to increase your swap without the need for a reboot.
First check your current swap size and details;
swap -lh
or
zfs list
Then create a temp swap zfs store and delete and increase swap
zfs create -V <old size> rpool/swp
swap -a /dev/zvol/dsk/rpool/swp
swap -d /dev/zvol/dsk/rpool/swap
zfs destroy rpool/swap
zfs create -V <new size> rpool/swap
swap -a /dev/zvol/dsk/rpool/swap
swap -d /dev/zvol/dsk/rpool/swp
zfs destroy rpool/swp
Done.
If you are happy to reboot…
zfs set volsize=8G rpool/swap
reboot
