2008.next: Recovering a dropped data pool
As you update your pkg
(5)-based system to build 100a, you might see a message on console during startup. It will look something like
WARNING: pool 'zeta1' could not be loaded as it was last accessed by another system (host: rosseau hostid: 0x581d45e). See: http://www.sun.com/msg/ZFS-8000-EY
and in /var/adm/messages
, you’ll find it again:
Oct 27 14:55:21 rosseau zfs: [ID 427000 kern.warning] WARNING: pool 'zeta1' could not be loaded as it was last accessed by another system (host: rosseau hostid: 0x581d45e). See: http://www.sun.com/msg/ZFS-8000-EY
zeta1
is a data pool on my system—the boot pool, rpool
, upgraded normally—and recent changes in the hostid
implementation mean that we have to import (or reimport) any non-boot pools on the system. That is,
$ pfexec zpool import -f zeta1
and our zeta1
-based filesystems are again online.
