 Description   

[ From BZ23877]:

Because the server modules require ldiskfs to properly function, the lustre-module rpms should really require the ldiskfs rpm. Currently because there are no dependencies between the two, the lustre-modules can get installed before the ldiskfs modules, and harmless but worrisome error messages pop up on the screen.

LU-97 lustre-modules should depend on ldiskfs.

This will break in the not too distant future when we have alternative disk filesystems. Would it be possible to change the ldiskfs package to provide lustre-backend-fs and the lustre-modules can require that instead?

This change has broken client-only module installation when the client auto-detects that this isn't a patched kernel (i.e. for most user builds):

checking for /usr/src/kernels/2.6.32.26-175.fc12.x86_64/include/linux/lustre_version.h... no

rpm -i /usr/src/redhat/RPMS/x86_64/lustre-modules-2.0.63-2.6.32.26_175.fc12.x86_64_gf80d83c.x86_64.rpm
error: Failed dependencies:
lustre-backend-fs is needed by lustre-modules-2.0.63-2.6.32.26_175.fc12.x86_64_gf80d83c.x86_64

It seems that the automatically-detected kernel support is not the same as specifying --disable-server (which I assume works for client-only RPMs or this issue would have been reported before now).

How do I get pass this? Building patchless clients for lustre 2.0.62/63 (EXT4 on servers). I've tried excluding ext4, --disable-server on client..

  1. rpm -ivh lustre-modules-2.0.63-2.6.18_238.12.1.el5xen_g78ed463.x86_64.rpm lustre-2.0.63-2.6.18_238.12.1.el5xen_g78ed463.x86_64.rpm
    error: Failed dependencies:

While this is being fixed, you can just install the rpm with "rpm -i --nodeps".

The problem originally described in this ticket is no longer an issue on master.
