I can't answer as an "internals" guy, but I can say this: I accidentally knocked the power off my external drive, which contains a pool. I quickly reconnected it. A few days later I noticed the machine was essentially nonresponsive, and had to power cycle it. It is possible that something else happened in the meantime, to put the machine into a bad state, but at least it's highly suspect that this happened after I kicked the power. I never tested this scientifically. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
