A downgrade from read-write to read-only does a complete flush of the filesystem before setting the clean bit in the superblock. So, even if you have been running async before or even during the period that you do the downgrade to read-only, you will not trash the filesystem. I do not believe that you are lying to anybody by deleting the commentary about cycling between read-only and read-write. Appropriate warnings about async are called for, however the only warning necessary about cycling between sync and async is that the danger of async does not go away for several minutes after you have cycled to sync. ~Kirk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
