Getting "Error fallocating extra space : Operation not supported" error while extending gfs2

Issue

• I am getting the error Error fallocating extra space : Operation not supported while trying to extend the gfs2 filesystem but I can see filesystem is being extended. Could you let me know that I can ignore this message?

[root@system ~]# gfs2_tool df /dev/mapper/logvg-d92
