And today I happened to be chatting to another Solaris 10 administrator who has seen precisely the same bug manifest itself on a terabyte zpool getting lots of I/O. So that's three cases. I certainly hope Sun get to the bottom of this one sooner rather than later ... and that btrfs gets out of alpha sooner than later. - d. _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
