Hi,

zypper dup of one 42.3 system to 15.0 on a VBox guest.

After this question:

1904 packages to upgrade, 607 to downgrade, 762 new, 291 to remove, 8 to
change vendor, 8 to change arch.
Overall download size: 1.97 GiB. Already cached: 0 B. After the operation,
additional 1.3 GiB will be used.
Continue? [y/n/...? shows all options] (y):
Do you agree with the terms of the license? [yes/no] (no): yes

The system gets busy for minutes with snapper.py, and later with
btrfs-defrag-pl, but there are no btrfs partitions at all:


lsblk --output NAME,KNAME,RA,RM,RO,SIZE,TYPE,FSTYPE,LABEL,

NAME KNAME RA RM RO SIZE TYPE FSTYPE LABEL
sda sda 512 0 0 20G disk
├─sda1 sda1 512 0 0 7M part
├─sda2 sda2 512 0 0 4G part swap swap_1
├─sda3 sda3 512 0 0 10G part ext4 Main
└─sda4 sda4 512 0 0 6G part xfs Home
sdb sdb 512 0 0 20G disk
├─sdb1 sdb1 512 0 0 4G part swap swap_2
├─sdb2 sdb2 512 0 0 12G part ext4 Usr
└─sdb3 sdb3 512 0 0 4G part crypto_LUKS
└─cr_sdb3 dm-0 512 0 0 4G crypt xfs

I can understand testing for btrfs then exiting, but it takes minutes at 100%
CPU.


we had like many posts on the list complaining about this stuff
already, only apparently rarely ever any officials or in charge care
also look at your diagram, where do you see any btrfs fs there? why is
the command or the tool even called btrfs when it runs for nonbtrfs
people? or why does it run and eat resources when there is no btrfs fs
around? what does it do? sell your cpu cycles to your power company?
