How to resize DRBD disk on LVM?

this is my drbd config

resource mysql {

    protocol C;

    floating 10.100.101.1:7788 {
            device   /dev/drbd0;
            disk     /dev/VolGroup00/LogVol02;
            meta-disk       internal;
    }

    floating 10.100.101.2:7788 {
            device   /dev/drbd0;
    disk     /dev/VolGroup01/LogVol02;
    meta-disk   internal;
    }
}

disk on LVMs on both nodes was set to 50G, I increased it with LVM on both nodes +4G (54G total now)

but when I try to run

[root@db1 ~]# resize2fs /dev/VolGroup00/LogVol02
resize2fs 1.39 (29-May-2006)
resize2fs: Device or resource busy while trying to open /dev/VolGroup00/LogVol02
Couldn't find valid filesystem superblock.
[root@db1 ~]# 

It says I can't. What should I do? Should I stop DRBD? And if so - should I do additional steps after resizing and starting up DRBD?

thanks, Dmitry
