I have successfully used mount -o snapshot on volumes less than 30Gb, but when I use it on my 150GB volume, the command hangs and slowly every other process hangs as well. This behavior is observed on both a RC2 system and on a 5.0-RELEASE system. >How-To-Repeat: Install FreeBSD 5.0 on a system with a 200GB disk. mkdir /usr/snapshots mount -u -o snapshot /usr/snapshots/snap1 /usr System slowly hangs; the mount command doesn't come back, even after crunching for more than 2 days. >Fix: Fix the code? >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
