Bug ID: 417139
Summary: LUKS(1) resize2fs command with wrong destination size?
Product: partitionmanager
Version: 4.0.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: tim.ban...@gmail.com
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
1.
run xubuntu 19.10, then download and apt install
partitionmanager (4.0.0-2)
libkpmcore8 (4.0.1-2) from
https://packages.ubuntu.com/focal/admin/partitionmanager
2. unlock, and resize LUKS(1) ext4 partition (from 2.7TB to 6.3TB)
OBSERVED RESULT
after resize, partition has correct size, but not the filesystem. A resize2fs
-p /dev/sdb needed to be executed to also resize the filesystem
EXPECTED RESULT
after resize, both partition, and fileystem have desired size
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: xubuntu 19.10 live CD with 4.0.0-2 packages to have latest
partitionmanager
(available in About System)
KDE Plasma Version: XFCE
KDE Frameworks Version:
Qt Version:
ADDITIONAL INFORMATION
I initially thought I created a LUKSv2 partition (that's why I wanted to run
4.0.0-2), but found out that back then I created a LUKSv1 partition. Anyway,
the resize was thus wrong with LUKSv1
