Ok, but using -L causes dump to create a filesystem snapshot, which is read- only, meaning that nobody can delete a file from it during the dump process. My guess would be that something is causing the snapshot to fail, which will cause dump to issue a warning and then continue without making a snapshot. Can you provide the output of dump while doing the dump? -- Bill Moran http://www.potentialtech.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
