[LU-3450] lustre-ldiskfs upgrades don't get installed when upgrading from yum

• Type: Story
• Resolution: Unresolved
• Priority: Major
• Affects Version/s: Lustre 2.3.0, Lustre 2.1.6

Description

To reproduce:

• Install Lustre 2.1.x on server A
• Create a yum repository serving Lustre 2.3.x packages on server B
• Edit yum configuration on server A to point to new repo on server B
• Run "yum update lustre" on server A

Expected outcome:

• All the Lustre packages on Server A upgraded to the 2.3.x versions

Actual outcome:

• All the Lustre packages except lustre-ldiskfs are upgraded – lustre-ldiskfs remains at the 2.1.x version, causing subsequent filesystem mounts to fail due to the old version of ldiskfs.

Background:

• lustre-modules depends on lustre-backing-fs, which is provided by lustre-ldiskfs. However, there are no versions specified in this dependency chain, so when a 2.1.x lustre-ldiskfs is already installed, that satisfies the dependency of the lustre 2.3.x lustre-modules. As a result, yum sees no need to install the updated ldiskfs package.

Suggested fix:

• Make lustre-modules depend on a specific version of lustre-backend-fs or lustre-ldiskfs
