I'm not sure.

Below, you do not include information about the current size of your DRBD.
check:
# grep drbd /proc/partitions

if that does not yet show the expected result,
try the "drbdadm resize" again, on both nodes, just to be sure.

if that already shows the expected result,
maybe you just forgot to resize the filesystem?

resize2fs, xfs_growfs, whatever is necessary for your file system.
