Description Ryan Kimbrell 2020-01-03 17:36:06 UTC

Description of problem: cloud-utils-growpart fails to resize a root partition on LVM.


Version-Release number of selected component (if applicable): 0.29-5


How reproducible: Always


Steps to Reproduce:
1. Install cloud-utils-growpart in a VM image.
2. Create a new VM from the image with a drive larger than the original.
3. Boot the VM and allow cloud-init to run.

Actual results:
Root drive (/) is not resized.


Expected results:
Root (/) should take up the remaining space of the new, larger drive.


Additional info:
/var/log/cloud-init.log reports:

cc_growpart.py[DEBUG]: '/' SKIPPED: device_part_info(/dev/mapper/vg-lv_root) failed: /dev/mapper/vg-lv_root not a partition

Resizing / on LVM worked in RHEL 7.5, but now fails in RHEL 7.7. I have not tried RHEL 7.6.

Comment 2 Ryan Kimbrell 2020-01-03 18:15:44 UTC

I just tried growing the root partition on RHEL 7.5 again and I receive the same error. Now I am unsure how I got this to work on RHEL 7.5 six months.

Comment 9 Rick Barry 2020-06-22 11:49:34 UTC

It's too late to add this capability to RHEL 7.9 and RHEL 7 in general is in maintenance support phase. We'll look at this in RHEL-8 (refer to bug 1810878).
