[OpenIndiana-discuss] Zpool crashes system on reboot and import

[Jim Klimov]

Also, that thread mentions that you may use this work around with
the read-only dataset with the pool to enable writes to the dataset
and keeping it read-only before exporting the pool. Still, yes,
"budy" mentions setting the dataset attribute while the pool is
imported read-only (Stephan? would you chime in with more details,
if that's really you?)

If you manage to reproduce this trick in command-line and if it does
indeed help (and if you want to keep using this pool i.e. to help
the developers reproduce and fix the core problem) instead of just
remaking the pool, you might build on the (unbaked as of yet) scripts
and SMF manifests here:

http://wiki.openindiana.org/oi/Advanced+-+ZFS+Pools+as+SMF+services+and+iSCSI+loopback+mounts

This would enable you to code all this logic about setting and removing
the readonly bits from your pool around the import-as-a-service, so that
your system would "gracefully" import the pool, enable the dataset, etc.
and undo this upon proper shutdown.

HTH,
