Re: Certifications
I agree. The RHCE exam put enough pressure on you to simulate a real world troubleshooting event. [EMAIL PROTECTED] 01/09/06 9:57 am Phil, My personal experience has been that most vendors certification programs are either far too easy where you can make intelligent guesses to pass (multiple choice question types) or too broad in focus (jack of all trades, master of none..). The one exception has been the RHCE. The RHCE exam is completely hands-on and really requires practical OS experience and knowledge to pass. You can be fairly certain that someone with an RHCE knows how to set up, configure and most importantly troubleshoot and fix RHEL related issues. It is pretty expensive at $750 just to take the exam, so if you're paying for it yourself it would be best to know what you are jumping into prior to taking it. I do know a number of experienced Unix professionals that have failed it.

Re: VM Setup
Thanks for verifying that. So here is what I'm currently seeing. During the install I can see the Linux installer pinging my nfs server and it replys back but never reaches my Suse VM. I put a static route in the nfs server to point to the VM4.3 machine for the IP of the Suse install. This didn't help.

Does VM have to route me out to the default gateway? Yes. And this is probably your problem. VM is likely to already be routing you out, but whatever is upstream of VM in the network doesn't know that to get to your address it has to go through VM. Either your network guys will have to configure a static route, or they will have to accept dynamic routing updates from VM and VM will have to announce the route to your Linux guest. The CTC itself is (from the Linux perspective) simply a point-to-point IP link; think of it like dialup PPP if you like. If you're running z/VM 4.2 with recent service or anything later, you probably want to use Guest LANs instead, as they're a lot more like just working with an Ethernet adapter.

If there's a subnet defined then everything probably thinks it can talk to everything else directly, which it can't: it's gotta go through VM. Is your NFS server another Linux virtual machine, or a desktop system, or what? Can you draw an ASCII picture of your network setup and who has which IP address and (importantly) netmask?

Re: Shared /usr
Thanks for the reply. This info will help me make the decision on wether to use shared /usr or not. -Doug [EMAIL PROTECTED] 9/10/2004 3:16:33 PM This is one possible architecture. Whether it's recommended or not depends on why you want to do it. The advantages are 1) saving disk space. Depending on how expensive dasd is in your organization, this can be considerable. 2) Allowing minidisk cacheing to take place, reducing the number of physical I/O's and speeding up response. 3) keeping your users from installing programs or making modifications on their own and then calling you at three in the morning when their server goes down. then you find out after two hours of work that the problem is some modification they made. 4) Creating a standard version of Linux that is easily deployable. The disadvantages are: 1) Service is much more difficult. You have to install updates on a test server, then compare before and after with tripwire to see what files were updated on /usr and which were not. You have to route the non-/usr files around then swap /usr disks and reboot. You end up having almost as many /usr disks with different versions on them than you would have if everybody just had their own disk. I've got 38 servers and 6 different shared /usr disks, not to mention 4 or 5 servers with non-shared /usr. 2) you have altercations with users who want to write to the /usr disk. Usually you can get around it by loop-mounting a subdirectory in /home over a /usr subdirectory. Installing WebSphere with a read-only /usr is virtually impossible, as are other program products. I'd say if all of your linux servers are essentially identical, shared /usr makes a lot of sense. If they are all configured differently, question it. We've been using shared /usr for about three years. We are considering going to individual read-write /usr areas with SLES9, just for the ease in maintenance. Disk is cheap here. We bill our customers only $6.14 per gigabyte per month for 3390 dasd storage. A full-pack 3390-3 for /usr is about 80% full and is about 2.2GB.

Re: Shared /usr
The maintenance is what would get me. We will have a customised set of packages for each installation because each linux install will have a different task. For our setup the maintenance overhead alone seems like enough to keep me from exploring it too much. Besides, you make it sound so fun [EMAIL PROTECTED] 9/13/2004 12:11:14 PM I have a question about sharing /usr with multiple vm guests. Is this a recommended acrchitecture? Are there any benefits to doing this other than saving space. It seems to me this could be problematic when applying fixes from yast. I welcome any input on this subject. I do this all the time (both PC class and mainframe class Linux). On the mainframe, you get some storage constraint relief which is theoretically important because you might be running thousands of Linux instances. In any case, you get tremendous installation and maint relief, with some substantial caveats. Any time you have shared filesystem storage (shared disks) and you then perform an installation or upgrade, there will be some pieces that fall into the shared storage and some that fall outside of the shared areas. Bringing these into sanity, between the master where you did the maint and the slaves (or ... give me a better term) :-S which access that shared storage, is a pain. You can re-run RPM on the sharers (the slaves), and you'll get a bazillion errors. You can probably ignore most of the errors. But are you really sure? Besides, it's inelegant. And what about customizations? You might need to distribute your own special config of whatever you installed or upgraded. Re-running RPM on all your sharers would probably not get your custom config kicked out to them. RPM does not deal with read-only volumes. IT WOULD BE NICE if it could/would check the file to be installed (into a R/O directory) and IFF the file to be placed there matches a file already there, ignore the fact that he (RPM) cannot write the file he wants to write. It's already there! Right? But if you can put up with stuff like this, then I recommend sharing /usr (and /opt). No sarcasm here: I really run this way all the time.

You should be able to use a backup superblock on that filesystem. You can use e2fsck -b x where x is the location of the backup superblock. This location changes depending on block size of the filesystem. If your filesystem was created with 4k block size the your first backup super block would be at 32768.
