Re: What is a good generic disk layout?
2) Click Create = choose /dev/dasda = choose Do not format = enter all blanks for Mount point (I see now that the last entry in the dropdown menu is blanks - aha - the hidden key :)). This is what I've always done. If you want to give a partition to LVM, you have to create it first. That is good that you've always done it correctly. I guess I'm not such a great SLES installer :(( I notice that the SP2 release notes address this issue, but perhaps the process to create logical volumes via the installer is not as intuitive as possible? The current Virtualization Cookbook on linuxvm.org/present recommends that the dasdfmt button be used to create an empty partition for use by LVM later. That seemed to work quickly on SLES 10 vanilla, suggesting that it is really doing an fdasd -a. Now on SLES 10 SP2 that button does seem to take longer, so I assume it is really doing a dasdfmt as the button suggests. The disks probably do not need to be dasdfmt'd twice, so if you want to create logical volumes, the correct answer seems to be to use the Edit Partition window and then select Do not format and an emtpy mount point. I see that now. But perhaps to make the installer more intuitive the following could be implemented: after the Create button is clicked, the user be presented with a choice of disks, but rather than just OK and Cancel, the choices are Empty partition, Mounted partition and Cancel. Then the resulting window from Empty Partition would not require the user to select Do not format and and empty mount point, but would just require that partition size - the only parameter that is pertinent. I know getting developers to recognize usability issues is difficult, so this is just a suggestion.

Re: What is a good generic disk layout?
Mark, It's always worked fine for me. I just went through a new SP1 install on my test What steps did you take? I found if you leave space on /dev/dasda, then click LVM, that the free space on /dev/dasda would not be available for use in a volume group. system, just to make sure nothing had changed with SP1. I am using a SLES 10 SP2 beta - but I will assume that should not be any different. A colleague suggested a way to get this accomplished. I have two 3338 cyl minidisks that become /dev/dasda and /dev/dasdb. From the Expert Partitioner window: 1) Click Create = choose /dev/dasda = choose Format, ext3 = choose your size and Mount point (/ for example) 2) Click Create = choose /dev/dasda = choose Do not format = enter all blanks for Mount point (I see now that the last entry in the dropdown menu is blanks - aha - the hidden key :)). Then when you click the LVM button /dev/dasda2 and /dev/dasdb are available. Note the inconsistentcy - I did not have to create a /dev/dasdb1 for /dev/dasdb to be available to LVM, but I did have to do this extra step for /dev/dasda. I would suggest for the installer to be more usable, that any volume with free space be available for use by LVM. Or there should be an entry on the Create a primary partition window to suggest for use with LVM. FWIW.

Re: What is a good generic disk layout?

Pretty much. The base /etc gets one /etc/init.d/boot.d/ script entry that remounts the other /etc over the top of the one in the root, and startup proceeds from there using the other /etc. If that fails, then you go directly to single-user mode with no network enabled to let you go fix whatever it's whinging about. Our setup also runs a small script to use CP MSG to scream to a PROP machine to let some human know about the problem. Bill Scully at CA did a nice paper/presentation on the basic idea, which I've tinkered with a bit more to make it use more VM facilities. I actually don't mount the base /etc; I want that centrally maintained and as R/O as I can make it. That shouldn't change often, if ever -- probably once a major release when I build a new template machine. Much easier to deal with overall, and scales nicely without having all that / in LVM mess involved. I suspect one could get really clever and put the initial / in a DCSS, which would promote even more sharing -- it's basically configuring a primarily diskless workstation with some local disks at that point.

Re: What is a good generic disk layout?
Hi all, Just a followup question (Mike and I are working together on this): We're considering this layout due to some difficulty we had in the SLES installer. Ideally, we'd like a 3338 cylinder 100 disk with /boot (ext3 filesystem) and the remaining space used for an LVM volume, so 2 partitions total. However, when we create the /boot ext3 partition, the LVM button doesn't allow us to use dasda any longer for a Volume Group. If we take off /boot, we can use dasda, but since /boot can't be on the LVM this won't work either. It's almost like once you put an ext3 filesystem on dasda, you can no longer use it for LVM. Has anyone run into this situation before? If so, is there a way to put 2 partitions (1 ext3, 1 LVM PV) on dasda during install?

Hi all, Just a followup question (Mike and I are working together on this): We're considering this layout due to some difficulty we had in the SLES installer. Ideally, we'd like a 3338 cylinder 100 disk with /boot (ext3 filesystem) and the remaining space used for an LVM volume, so 2 partitions total. However, when we create the /boot ext3 partition, the LVM button doesn't allow us to use dasda any longer for a Volume Group. If we take off /boot, we can use dasda, but since /boot can't be on the LVM this won't work either. It's almost like once you put an ext3 filesystem on dasda, you can no longer use it for LVM. Has anyone run into this situation before? If so, is there a way to put 2 partitions (1 ext3, 1 LVM PV) on dasda during install?

Re: What is a good generic disk layout?
X and a graphical desktop? Should we be encouraging this? Installing them and running them are two different things. It's sometimes nice to have one installed so it can be started only when a graphical environment is necessary. But you do bring up a good point. can't you make partition1 dasda1 /boot and partition2 dasda2 the PV for LVM? I could not figure how to do that with the SLES installer. It seems once you use a volume for a conventional file system, it precludes the remainder of the volume from being used for LVM, and vice versa.

Re: What is a good generic disk layout?
I understand that, and the installation and use of X should be the exception, not the rule. Software that require X for installation being the exception (but should be encouraged to provide a non-graphical alternative). I still think in this shared environment that we should not be tempting admins with the potential to be starting up graphical environments on any whim. DB2 does have a silent installation option, X is not required (and it goes ALOT faster). Fargusson.Alan wrote: Some products can only be installed from an X11 session. It seems like DB2 is one.

Ideally, we'd like a 3338 cylinder 100 disk with /boot (ext3 filesystem) and the remaining space used for an LVM volume, so 2 partitions total. However, when we create the /boot ext3 partition, the LVM button doesn't allow us to use dasda any longer for a Volume Group. If we take off /boot, we can use dasda, but since /boot can't be on the LVM this won't work either. It's almost like once you put an ext3 filesystem on dasda, you can no longer use it for LVM. Has anyone run into this situation before? If so, is there a way to put 2 partitions (1 ext3, 1 LVM PV) on dasda during install? It's always worked fine for me. I just went through a new SP1 install on my test system, just to make sure nothing had changed with SP1. I even tried it a couple of ways: /dev/dasda1 - /boot /dev/dasda2 - PV for VG system /dev/dasda1 - / /dev/dasda2 - PV for VG system Worked fine both ways. What, exactly, are you doing, and in what order? What error messages are you seeing? Etc. For all you folks out there that keep wanting to put / in an LV, all I can say is masochists.
