Perhaps your kernel/world is not recent enough? There used to be problems with snapshots, including hangs or crashes, but IIRC, they disappeared completly a couple of months ago, at least for me. (no, sorry, I can't pinpoint the exact date, and much less the exact revision nr). Snapshots alone, and dump -L + restore (on RELENG_7/amd64) working flawlessly here on 20+ rack-mounted servers; some to tape, some to SAN, but I'm probably just lucky. BTW, that's what makes this problem so intractable: those who could debug it, can't reproduce it on their machines. It's scary to know there's a bug lurking in there. > -mi -cpghost. -- Cordula's Web. http://www.cordula.ws/ _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
