What were you trying to do that didn't work?
When a customer has XFS mount points that get "escaped" to be mounted as overlays, e.g. /var/tmp and /var_tmp, there is collision on the escape character (which is underscore), causing the following backtrace to be encountered:
MountError: Mount operation with mode loop from /var/lib/leapp/scratch/diskimages/root_var_tmp to /var/lib/leapp/scratch/mounts/root_var_tmp failed: Command ['mount', '-o', 'loop', '/var/lib/leapp/scratch/diskimages/root_var_tmp', '/var/lib/leapp/scratch/mounts/root_var_tmp'] failed with exit code 32.
What is the impact of this issue to you?
Prevents leapping
Please provide the package NVR for which the bug is seen:
leapp-upgrade-el7toel8-0.20.0-9.el7_9.noarch
How reproducible is this bug?:
Always
Steps to reproduce
- Add a disk to host 2 file systems, /var/tmp and a /var_tmp
# vgcreate data /dev/vdb # lvcreate -n tmp -L 1G data # lvcreate -n var_tmp -L 1G data # mkfs.xfs /dev/data/tmp # mkfs.xfs /dev/data/var_tmp
- Add the file systems in /etc/fstab
# mkdir /var_tmp # echo "/dev/mapper/data-tmp /var/tmp xfs defaults 0 0" >> /etc/fstab # echo "/dev/mapper/data-var_tmp /var_tmp xfs defaults 0 0" >> /etc/fstab # systemctl daemon-reload # mount -a
- Execute leapp upgrade
Expected results
No backtrace
Actual results
