Re: About Unix <- Doug needs a good rebuking Lourdes' husband here -- Okay Doug, you are so full of crap, my wife came to me with questions based on your misinformation. That's sad. Learn the systems and only talk about _what_you_know_! I rebuke your comments below. The key here is _technical_facts_. Now if you want to talk about those, come to ELUG (http://www.elug.org). We cater to all OSS (Open Source Software) users.

I have never, ever had to re-install. Same goes for BSD (which I've used limitedly since 1995 as well). [ Side note: I've been an NT administrator even longer (1992-1999), and re-installs are a fact of life (not as bad as Win9x -- but I find NTFS will destroy itself after 2-3 years of good use when it "assumes" a journal flush is good). ] Now I know you are _trying_ to "stress" the fact that most Linux distributions don't come with a "journaling filesystem", but the default, Linux Ext2 filesystem is quite a reliable filesystem, despite its simplicity. In fact, of all the major UFS (UNIX Filesystems), it fragments the least (although fragmentation on any UFS not even close to being as bad as any Windows OS). > We did have exclusively linux in our servers but since the changeover to > FreeBSD the uptimes have increased to the point where machines > generally keep going constantly from one upgrade til the next ... usually > a year or so later.

Everyone's going to have their own comments. My main Linux-based Samba-NFS file server (which also does mail, CVS and everything else under the sun) for over 50 NT, Solaris and Linux clients is running RedHat 6.2 with kernel 2.2.16+Ext3+NFS3. Crash recovery times are <<5 minutes -- but I've only seen that happen once. It stays up forever (until stupid Florida Power goes down). "Denis J.

Journaling FS rocks, but I haven't seen any for FreeBSD. ReiserFS has issues as an NFS server. Regardless, I have extensive knowledge of Ext3 on *PRODUCTION* systems. I'm also moving into using XFS (I repackage their kernels from CVS in RPM format) since Ext3 doesn't run on 2.4. XFS is a pretty advanced system. I recently did a presentation on Linux JFS options (focus on Ext3 and XFS). You can find it here: http://www.smithconcepts.com/files/presentations/ELUG_JFS_2001Mar05a.pdf > One I must say that *BSD under heavy load are more powerfull. That's the power of its mature VM and scheduler systems. Linux is getting there. Linux 2.4 really improves _a_lot_. Linus is getting good at balancing simplicity and single-user performance against server/multiuser performance. -- Bryan "TheBS" Smith Engineering/SysAdmin, Theseus Logic, Inc.
