Service redundancy : CARP, wackmole/spread, 4.x / 5.x
Hi all, I'm looking into adding some automatic failover for some services. I'd like to hear comments / advice on suitability of either CARP / FreeVRRP / wackamole + spread for these 2 different setups (see below) The setups are completelly independent of each other, so different solutions / approaches for each are OK. Of course, I'm not interested in adding special hardware to do any of this, but if there are *significant* advantages of a hardware solution, i'd like to hear too :). Setup 1) : - FreeBSD 4.11 Server, 3 x NICs (fxp, LAN/WAN/DMZ). - Firewall (ipf, but thinking of moving to ipfw), ipnat - about 4 jails (secure FTP, email gateway with antispam, and AV). - Unmanaged switches used throughout. - No mysql / DBs. - email load is low (20 LAN users, but *heavy* users). The idea is to add another server and be able to gracefully take over all the functionality with no or very minimum downtime. For this setup, I was thinking of CARP, but it isn't supported in 4.x? Setup 2): - 4 x FreeBSD 5.4 Web Servers, 2 NICs (Wan + Private Lan), utilising a full 100 Mbps link overall. (not sure if important, but each server also has HP's iLO standard on its own CAT 5, to the same switch). - Behind Cisco managed switch. - Apache 2.0, no DB in place. - Currently on a simple DNS round-robin setup. - No VRRP running on other switches on this segment of the datacentre, AFAIK - How would CARP with arpbalance work on this situation? (would have to change the DNS to 1 IP,the virtual IP right?) Or is it better to go wackmole/spread? I had some problems a few years ago with wack/spread on 8 servers running 4.x : if a server went down, another would pick up the IP..but never release it when the original came back up - never figured out what the problem was (possibly config?) thanks in advance for your help comments, Beto ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
4.x - 5.x
Hello, it must be a well-discussed topic, but I don't know where to find a good description about upgrading from 4.x to 5.x. There is a production machine running 4.10 and the owner wants me to upgrade it to 5.4. Could somebody tell me the most important points to care? Or do You know a good howto?

I don't know a good howto but I did a source upgrade from 4.11 to 5.3 a while back. I ran into a few issues (due to laziness on my part): Some changes in kernel config files for building custom kernel. Some changes in /etc (especially rc.conf). I wound up installing a fresh /etc and then manually adding my changes. Significant changes to the disk sub-system. I'm using vinum for disk mirroring. If you are using vinum, read up on gvinum carefully. I migrated too soon. Should have waited for 5.4. 5.4 is much better than 5.3. -- Ean Kingston E-Mail: ean AT hedron DOT org URL: http://www.hedron.org/ I am currently looking for work.

Dual-boot FreeBSD 4.x/5.x
Is it possible to dual boot FreeBSD 4.9 and 5.2.1 on one system, each using a different / partition, but sharing the same /usr partition for example? I'd really like to try out some of the features of 5.x, but be able to easily go back to 4.9 if I find it too unstable. -- I sense much NT in you. NT leads to Bluescreen.

There are too many differences. Anyway, you could not install binaries for one and expect them to run in the other. jerry --=20 I sense much NT in you. NT leads to Bluescreen.

4.x - 5.x
quick question -- please CC me, i am not currently subscribed to -questions... (TIA.) i'm throwing together a migrating from 4.x to 5.x doc targetted at beginning - intermediate audiences. i say that, because a large part of the doc is an install section with a step by step (including screenshots) installation guide. the first thing i address is backing up local customizations to the 4.x environment. things like /etc, /usr/local/etc, databases, etc. my question is, what's the best way to move 4.x packages to 5.x? i'm not talking binaries of course, but reproducing the set of installed packages from data in /var/db/pkg. i've read through the man pages for pkg*, portupgrade, etc... and i'm thinking it may be simple enough to just tar /var/db/pkg under 4.x, restore under 5.x, and then portupgrade the tree. i've tried it with a couple ports and it works, but i haven't tried it with an entire tree yet (more complex, with more dependencies to keep straight). am i headed in the right direction, or is this a bad idea. :) this is just to get the same set of binaries back on the 5.x system, merging configs, etc. is given it's own blurbage. thanks, -mrh -- From: Spam Catcher [EMAIL PROTECTED] To: [EMAIL PROTECTED] Do NOT send email to the address listed above or you will be added to a blacklist! ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Actually, this sounds like a very clever way of reproducing your ports setup. A portupgrade -fRr \* should do the trick. Wish I'd thought of it first..
