Storage: August 2011 Archives

If you accidentally upgraded your root zfs pool (which is not recommended until it is supposed to be done from Oracle) do not forget to update your boot signature,  your boot archive and your grub installation -

but do not reboot before having done this, otherwise the system won't boot any more.

Don't upgrade the root pool! You won't be able to repair your system when booting from the actual Solaris 10 boot CD (09/10) as the root pool cannot be mounted then. The following steps are to make sure that your system will at least boot when you did the upgrade accidentally.

Example:

Since Kernel patch/update 144501-19, Oracle now puts zpool version 29 and zfs version 5 into production.

One visible change is the more detailed status when doing a scrub or a resilver operation:

# zpool status
