No, although UFS2 with softupdates is robust enough for production use. If you make the filesystem writes syncronous and disable write caching on the hard drive, you will improve the robustness at significant cost to performance. Are you saying that the UFS2 file system sucks? Not at all, but standard IDE-drives suck when it comes to robustness. (They tend to lie and tell the OS that data has been written to the disk, when in reality it has only been written to the disks cache.) (Thus the advice above to turn off write-caching for maximum robustness.) If you use softupdates (on a disk that doesn't lie) the filesystem on the disk will always be consistent, but data written during the last 30 seconds or so might not yet have been written to the disk, and can therefore be lost if e.g. the power to the computer is turned off. Erik, does that mean if you use softupdates, (on a SCSI,) that, although file(s) currently being written may be truncated since the cache is not flushed, that the file system can be repaired automatically by fsck to a consistent state? That is the idea. With softupdates the filesystem *on the disk* should always be in a consistent state, such that fsck should always succeed. (At least that is the theory, I haven't tested how well it holds in reality.) Even without synchronous writes or enabling cache write through? John BTW, the reason for the question is that most SCSIs today have many meg of HW cache, and many, (maybe most,) controllers don't permit write through anymore. So, even if the OS flushes its cache, the HW cache may not be written to the disk-so synchronous writes and OS cache write through may be of little value. The only cache that can mess up things is that on the disk itself. Forget about any caches managed by the OS - they are handled by the filesystem code and flushed when needed. The cache on the disk is another matter. One difference between SCSI and IDE is that SCSI support tagging which lets the OS determine if a given block has actually been written to the disk or just to the disk's cache. This is needed for softupdates to work correctly. On IDE-disks this information is often not available which means that you may need to disable the write-cache on the disk (or at least make it write-through) to be able to rely on the guarantees of softupdates. A few IDE-disks and some of the newer S-ATA disks also support tagged queueing, but support for that is not nearly as good as it is for SCSI - not yet anyway. Are you saying that it's not safe to use softupdates on IDE drives? I've always used softupdates on IDE and never had a problem. However, I've never had a system that was under heave load. If lots of people are writing to the drive ( I'm thinking file server) under softupdates it sounds like something could go wrong. Lets say I have a small network of 25 users. Were going to install a file and print sever using FreeBSD 5.3 (UFS2). Because we don't have a lot of money we get SATA drives. Should I use softupdates or not? If I had more then 25 users I would consider getting SCSI. -- Damien Hull [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
upgrading 4.10 to 5.3
I'm trying to upgrade my 4.10 workstation to 5.3 but I'm not having any luck. In my search to find an answer I found some info saying that one shouldn't upgrade branches. That brings me to my first question. Should I upgrade from 4.10 to 5.3 or should I just setup a new 5.3 workstation? Here's where I am having trouble. 1. when trying to install the kernel I get this message telling me there is no /boot/device.hints file. After doing some research I found that there is a GENERIC.hints file in /usr/src/something/i386/conf/ (don't remember the exact location). I placed that file in /boot/ and installed the kernel. The kernel installs but I don't know if the GENERIC.hints file will work when I reboot. All I can say is that the kernel installed. That's when I moved on to mergemaster. 2. I had some trouble with mergemaster. Don't know what I did wrong here so I can't say much about it. I don't think I've ever had much luck with mergemaster. I'm going to give the upgrade another shot so maybe it will work this next time. 3. Somehow I was able to finish the mergemaster step and move on to installing my world. I did make installworld and a bunch of things went by on the screen and then I got errors and stop. I think it said something about a core dump. All I got out of it was that my upgrade didn't work. I used g4u to backup my 4.10 workstation before I did the upgrade. I'm doing my second restore as I write this. As soon as it finishes I'll cvsup and start all over. If anyone can tell me what I'm doing wrong let me know. Also, if you think I should just dump 4.10 and do a new install of 5.3 I can do that as well. I've got another drive I can install 5.3 on. I'm hoping I can upgrade so I don't have to configure a new 5.3 system. -- Damien Hull [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

FreeBSD or OpenBSD
I've been a FreeBSD user for a while now and I love it. I'm running 4.10 and plan on upgrading soon. I'm also an OpenBSD user but I tend to use it for firewalls and routers. I setup Apache and Subversion on OpenBSD 3.6 last week. This is the first time I have ever done anything other then a firewall on OpenBSD. I'm thinking about using OpenBSD on more servers. Before I do that I would like to know what people on the list think. Why I want to switch to OpenBSD. 1. OpenBSD has good security 2. Stable 3.

Apache on two nic's

Added a second network card to the server 2. connected the network card to the outside of the network 3. tired to connect to the website on the new IP address 4. Got nothing 5. Added a virtual server that listened on the new address but got nothing. I've looked at the Apache config file and there is a place to put in an IP address but I left that alone. As fare as I can tell it's listening to all addresses. Can someone tell me what I need to do to get this working?
