Thanks -- you've confirmed what I suspected, that I could have avoided the problems I saw by being a bit more cautious. My bad. Out of interest though, why do you advise not putting critical data on a Vinum R5 volume? This one has been running fine for ~2 years under reasonable loads. The disk failure was the first time it's required any attention at all, and it seems the problems I had with that were mostly of my own making. The mailing lists don't seem to be overrun with people complaining that 'Vinum ate my files' :-) Cheers, Scott -- =========================================================================== Scott Mitchell | PGP Key ID | "Eagles may soar, but weasels Cambridge, England | 0x54B171B9 | don't get sucked into jet engines" scott at fishballoon.org | 0xAA775B8B | -- Anon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
