No, it does not warn on my systems about attr2, either. Like I said, there are no warnings on remount at all because mount it not passing the /proc/mounts information back into the kernel: # strace -emount -v mount -o remount,ro /mnt/scratch mount("/dev/vdc", "/mnt/scratch", 0x561f3b93c690, MS_RDONLY|MS_REMOUNT, NULL) = 0 # This really looks like a mount version/distro issue, not a kernel issue...
