Description abelau@gmail.com 2024-06-19 11:31:38 UTC 
SUMMARY
btrfs raid1 with 2 partitions (sda1 sdb1)

KDE partition manager shows correct info:
Partition    Type    Mount Point     Label
/dev/sda1    btrfs    /mnt/point/  testbtrfs
/dev/sdb1    btrfs                 testbtrfs
Note: Mount Point of /dev/sdb1 is empty (matches with df)

Online Resize /dev/sda1 works as expected
Online Resize /dev/sdb1 returns below error:


OBSERVED RESULT

Job: Check file system on partition ‘/dev/sdb1’ 
Command: btrfs check --repair /dev/sdb1 
Check file system on partition ‘/dev/sdb1’: Error
Checking partition ‘/dev/sdb1’ before resize/move failed. 
Grow partition ‘/dev/sdb1’ from 97.66 GiB to 146.48 GiB: Error


EXPECTED RESULT

Online resize/grow successful


SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu 24.04 
(available in About System)
KDE Plasma Version: 5.27.11
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.13

ADDITIONAL INFORMATION
It looks like KDE Partition Manager is treating the 2nd disk in a btrfs raid1 array as unmounted, and not interpreting it as part of a btrfs raid1 array.
