read only root SSD

$
0
0
The next boot after the updates of 26 Aug I lost write access to my root partition on an SSD drive and internet (DNS fails but ip works). All indications are that the drive and partitions are mounted read write. Any attempt to change, add or delete files on the root device (/dev/sda1) gives "Read-only file system".
Example: in /root directory
# echo "test" > temp
-bash: temp: Read-only file system

Below are relevant files and outputs (zypp/history /etc/fstab /etc/mtab mount smartctl)
