Comment 27 for bug 1976228

Hello jeff,
This seems unrelated with external storage devices, I did the test on host with local disk only,
“rescan-scsi-bus.sh -r” remove local disks wrongly.
After excuting “rescan-scsi-bus.sh -r” ,whole / mount status change to ro:
/dev/mapper/ubuntu--vg-ubuntu--lv on / type ext4 (ro,relatime)

I hope this information will help you locate the issue,and find a solution to the script.

Br,
