I am facing below issue while mounting the file system with command.
su 0 mount -o rw,remount -t ext4 /system '/dev/block/dm-0' is read-only
Thanks in Advance.
Possibly dm-verity is in effect, please try to perform disable-verity.
Thank Victor, but its showing below error-
root:/ # disable-verity /system/bin/sh: disable-verity: not found
