Description Charles Timko 2023-06-20 17:32:37 UTC

Description of problem:
Running on an upgrade from CS8 to CS9, and I'm running into an issue with my VDO disk import. It appears that the script `lvm_import_vdo` relies on the `vdo` script but it is was deprecated and removed.

Version-Release number of selected component (if applicable):
2.03.21-1

How reproducible:
Run lvm_import_vdo and observe error.

Steps to Reproduce:
1. `# lvm_import_vdo --dry-run <known-vdo-volume-created-in-CS8>`

Actual results:

[root@core ~]# lvm_import_vdo --dry-run /dev/md1
lvm_import_vdo: Checked whether device /dev/md1 is already LV (0).
lvm_import_vdo: Getting YAML VDO configuration.
/sbin/lvm_import_vdo: line 278: vdo: command not found


Expected results:

Successful import.

Comment 1 Zdenek Kabelac 2023-06-20 17:39:38 UTC

Yep -  'lvm_import_vdo' is only working on RHEL8 -  and ATM is currently not usable on RHEL9 - as this distribution no longer provides 'vdo' manager.

Users of RHEL8 are supposed to upgrade their VDO volumes *before* they switch to RHEL9.


Packaging of lvm2 likely should be complaint and not package this conversion script for RHEL9 package.

Comment 2 Charles Timko 2023-06-20 17:48:53 UTC

Documentation should also be updated for RHEL 9 then - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/deduplicating_and_compressing_logical_volumes_on_rhel/proc_importing-existing-vdo-volumes-to-lvm_deduplicating-and-compressing-logical-volumes-on-rhel
