Describe the issue:
The instructions are not complete or do not really cater for all scenarios where the increase in storage is not seen after running docker-storage-setup.
The doc covers thinpool based setups, but doesn't cover xfs/overlay2.
Suggestions for improvement:
Please add a note to run the following command in case the increas ein size is not visible because the chosen filesystem is xfs/overlay2
The logical volume can be grown to use all the available space in volume group by using below command.
If the requirement is to use lesser space, choose the percentage accordingly.
# lvextend -l +100%FREE /dev/mapper/docker_vol-dockerlv
The filesystem can then be grown to use this space by running. xfs volumes can not be shrunk.
# xfs_growfs /dev/mapper/docker_vol-dockerlv
4. The customer can substitute above commands with singl command as well:
# lvextend -r -l +100%FREE /dev/mapper/docker_vol-dockerlv
OCP 3.6-3.10 is no longer on full support . Marking un-triaged bugs CLOSED DEFERRED. If you have a customer case with a support exception or have reproduced on 3.11+, please reopen and include those details. When reopening, please set the Version to the appropriate version where reproduced.
The same correction on the documentation applies for 3.11 as well. There is a mention of "The process may differ depending on the underlying OpenShift Container Platform infrastructure.". But this does not give the steps to fix it actually.
