Bug ID: 413883
Summary: Resizing luks-encrypted lvm2 pv doesn't actually
resize the physical volume
Product: partitionmanager
Version: 4.0.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: l...@z3ntu.xyz
Target Milestone: ---
SUMMARY
When a disk has "lvm2 pv [Encrypted]" which gets resized to be bigger, the
partition does get resized but the "physical volume" doesn't get resized and I
had to run "pvresize /dev/mapper/luks-123-123-my-uuid" manually for the
physical volume size to increase. Afterwards I could increase the ext4
partitions inside of my lvm volume.
STEPS TO REPRODUCE
$ fallocate -l 100MB test.img
$ sudo losetup /dev/loop5 test.img
# scan devices with KDE Partition Manager
# Create "New Partition Table" (GPT) on loop5
# Create "unformatted" partition with half the space -> Apply
$ sudo partprobe /dev/loop5 # for /dev/loop5p1 to appear
# Right click on partition -> Properties -> File system = lvm2 pv -> Apply
# Tools -> New Volume Group -> Apply
# Create new partition in new volume group with e.g. half the space
# Resize "lvm2 pv" partition to be bigger
# Observe, that the volume group didn't grow
# If the same was to be tried without luks encryption, the volume group does
grow to the new size.
OBSERVED RESULT
The lvm2 pv is not bigger
EXPECTED RESULT
The lvm2 pv should be bigger
