Problems when build a case using my own surfdata in CESM1.2.2

[zp_xie@foxmail_com]

Hi,  I have created a reginal surfdata file, and put it uder the $CSMDATA/cesm/lnd/clm2/surfdata_map, everything is ok for cesm1.2.1, but when I build  thesame case with cesm1.2.2, problem happens, the error is :**********************************************************************************CLM configure done.CLM adding use_case 2000_control defaults for var sim_year with val 2000 CLM adding use_case 2000_control defaults for var sim_year_range with val constant CLM adding use_case 2000_control defaults for var use_case_desc with val Conditions to simulate 2000 land-use CLM build-namelist ERROR: No default value found for fsurdat.            Are defaults provided for this resolution and land mask?ERROR: clm.buildnml.csh failedERROR from preview namelist - EXITING********************************************************************************** The error indicates that the clm can't find the surfdata, but I do ensure the file is exist, and the cesm1.2.1 can work successfully.

I don't know why, if the cesm1.2.2 needs to set something  else like  $CSMDATA.
Thanks.
