Description Zdenek Veleba 2021-04-15 13:20:47 UTC

Description of problem:
Kickstart installation with 'autopart --type thinp' fails on system with more than ~16TB of disk space.

Version-Release number of selected component (if applicable):
anaconda-33.16.4.15-1.el8
python3-blivet-3.2.2-10.el8

Steps to Reproduce:
Start automated installation with kickstart containing 'autopart --type thinp' on system with large disk space.
(it happened on system with 12x 4TB drives)

Actual results:
Non interactive installation failed: Process reported exit code 5:   WARNING: Chunk size is smaller then suggested minimum size 256.00 KiB. 
  Selected chunk size 64.00 KiB cannot address more then <15.88 TiB of thin pool data space. 

Expected results:
anaconda or python-blivet should automatically select valid chunk size and the installation should not fail

Additional info:
The bug was found on ppc64le system but I'm expecting the issue to affect all architectures.

Comment 6 Jiri Konecny 2021-04-16 08:14:26 UTC

Based on the traceback this seems to be an issue in the blivet. Switching component.
