Description Anthony Hogbin 2019-04-01 11:51:31 UTC
Description of problem:

 - When using resize of volume after creation in the %post to get around the issue of 20% being reserved for metadata in older versions the metadata daemon does not shutdown cleanly. As such, there is a 90-second delay before the reboot.
 - While this can be worked around for newer releases of, the fact remains it is not behaving as expected.

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

How reproducible:

- Easily reproducible.

Steps to Reproduce:

1. Kickstart creation of volume similar to:
  volgroup vg_system pv.001
  logvol none --fstype="None" --thinpool --name=lv_system_thinpool -- 
  vgname=vg_system --chunksize=64 --size=7688 --metadatasize=16
  logvol / --fstype=ext4 --name=lv_root --vgname=vg_system --size=4096 --thin --poolname=lv_system_thinpool
  logvol /var/lib/rpm --fstype=ext4 --name=lv_var_lib_rpm --vgname=vg_system --size=512 --thin --poolname=lv_system_thinpool --fsoptions=noexec,nosuid,nodev
2. Kickstart %post to then resize this volume:
  lvresize -l +100%FREE vg_system/lv_system_thinpool
3. On completion of install without quiet you will see it timing out to restart.

Actual results:

  [***  ] (1 of 2) A stop job is running for LVM2 metadata daemon (36s / 1min 30s)_
  [***  ] (2 of 2) A stop job is running for anaconda (46s / 1min 30s)_

Expected results:

 - lvm2 metadata daemon shutting down;
 - Machine restarting without delay;
 - Resizing a volume should not cause an issue.

Additional info:

 - Resize required prior to 7.4 due to space reservation:
