The kernel doesn't and shouldn't prevent it for the r/o-mounted case (since fsck needs to write to the partition of a mounted file system for at least the case of the root file system mounted r/o), and apparently growfs doesn't prevent it in ths case either. There are lots of safety belts in the kernel for the r/w-mounted case. Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
