Technically no, but the main reason to use a journaling FS is for stability in the face of adversity (such as when power is lost in the middle of a write) I have tested UFS (The FreeBSD filesystem) several times by killing the power during a write. It has never lost data as far as I can tell, and is certainly a much mor estable filesystem than EXT2 (the reason Journaling is such a buzzword) or FATxx (the infamous awful filesystem of the Microsoft world) With SoftUpdates, UFS is the second fastest filesystem that I have ever used, second to Irix's filesystem. (Speed measured with streaming large files, UFS probably beats Irix with many smaller files) If you need extreme filesystem stability, UFS set to write synchronously is stable enough to trust with a mission-critical system Of course, you should also have at least one UPS on that mission critical system too. ;) >From: "Ilya" <mail@krel.org> >To: <questions@FreeBSD.ORG> >Subject: journaling file system >Date: Sat, 31 Mar 2001 20:27:08 -0500 > >Does FreeBSD have any type of journal file system which it can natively >support? > > >To Unsubscribe: send mail to majordomo@FreeBSD.org >with "unsubscribe freebsd-questions" in the body of the message _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
