I’ve noticed a problem with remount /dev/loop29 i run this command on vm Instance to show you

# df -h

tmpfs            63G     0   63G   0% /sys/fs/cgroup

vm machine mount /dev/loop29 to /

# mount -o rw,remount /dev/loop29 /
mount: cannot remount /dev/loop29 read-write, is write-protected

I even tried to use CHMOD to grant full rw permission to files, but Chmod +777 ,CHATTR,hdparm -r 0 /dev/loop29
Does anyone else have an idea?
