[Docs][Install] If custom partitioning is used, it should be documented that /usr cannot be in its own partition
Last modified: 2017-07-14 05:38:39 EDT
Description of problem:
When using custom partitioning during RHVH installation, creating a separate partition for /usr will cause the installation to fail. It turns out that /usr should not be allocated in its own partition, and that this should be documented.
As such, the 'Advanced Installation' section of the RHV Installation Guide should be updated to document this limitation.
I would suggest according a note in the '6.2.1. Custom Partitioning' section.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Perform RHVH installation.
2. Select the custom partitioning option.
3. Include partition for /usr.
Can you confirm this is a limitation? Anything to add to this?
This is a definite limitation. /usr must be on an LV which is able to change versions along with RHVH (generally, leaving /usr on /)
Imagine that a user installs RHVH 4.0.7/7.3
The user then upgrades to RHVH 4.1/7.4
What state are /usr/lib, /usr/[s]bin, and other paths in? Probably they work with 7.4 library versions. But trying to roll back to 7.3 will result in broken linked library dependencies
Assigning to Avital for review.
Avital, we need to add a note as suggested in the Description, and include the reasoning from comment 2 ("/usr must be on an LV which is able to change versions along with RHVH (generally, leaving /usr on /)").
Final document release:
