Wish me luck...I'm about to cluster 2 production servers...

I need your prayers because I'm about to bond 2 servers that do totally separate tasks for the sake of fault tolerance. This scares me because if anything goes wrong, I could lose the services and it will be a heck of a lot of work to get it back. Please cross your fingers and hang on tight. It's going to be a bumpy ride for about 10 mins.
 
why dont you make ghost images of each server before hand to insure if you f up, you will have something to fall back on?

Because they're Netware 6 servers. 😛 I have backups of all the important information....I'm still testing the the ghosting software in my test bed now. I've been successful with it, but there are some low-level drivers needed to make it work. I'm going to have to work on that as soon as I get a chance to clear out one of my test 2650s. (we run Dell stuff here)
 
Ugh.....I hate clustering. Luckily through you are doing it with Netware. It's not the greatest but it's better than MS clustering....trust me...I have LOT of experience with MS clustering. That's why I just talked our CIO into buying me two new quad CPU servers to cluster with Linux.

Yeah, clustering with Linux is much nicer than clustering with anything else. We have eight dual cpu computers that we run in one of the clusters (Mosix) here, which is nice. 🙂

We tried MS clustering here and the main reason we went with Novell was because we jumped on an ALA and saved a lot of cash... We would have had to get an FTE deal for 14-15,000 users and that's expensive when dealing with Active Directory. Netware 6 provides soo many web-based solutions with the contract that we ended up replacing all our print servers, file servers, and Email servers... Plus we have a lot of services that we can expand to in the near future when we decide to. Needless to say, I'll be busy very shortly... The Email cutover date is in mid February. :Q
 
Just finished clustering two Redhat Linux servers for samba and nfs....boy was that fun since this company is kinda cheap had to raid the drives in each machine over the network...not fun at all. but its experience...🙂
 
Just out of curiousity, why do it in the middle of the week? Why not wait until Friday night or *gasp* come in on a Saturday to do it?

I'm putting Red Hat on the ones I have here. Luckily though they bought me some tricked out servers. Quad Xeon 1.6ghz CPU's in both, 4GB RAM in each box, mirrored 18GB 15k Ultra 3 SCSI drives for the boot partition, and my favorite part....dual Emulex LP9002L-F2 Fibre Channel Cards so that the system can be connected to our IBM Shark for all the storage(about 250GB worth) needs. This cluster is replacing a current MS Win2k Advanced Server cluster connected to a Compaq RA 4100 SAN that is our main app hosting, file sharing, and departmental storage system. Needless to say it gets quite a workout.....
