I then had: > df | grep 32_share /dev/wd1s3e 2031953 1353017 516380 72% /32_share /dev/wd0s3e 2032623 1169007 701007 63% /32_share Odd things started happening (vi failed, missing directories, etc.), so I rebooted. All is normal now, and nothing lost AFAIK, but that sure was strange. This looks like a bug. >How-To-Repeat: > mount /dev/wd1s1 /abc > mount /dev/wd1s2 /abc In this case, both were FreeBSD UFSs. >Fix: Unknown. I think that mount should issue an error when this is attempted. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
