[gmx-users] I/O problem

[Chen Hao]

Hi, I run MD simulation on a linux cluster, mdrun process running on 
compute host write files through NFS to disk array on server host. 
During the calculating process, the server host has some problem so I 
reboot the machine. After the server host starts, I check the files by 
gmxcheck and it says that ener.edr has something wrong, but I can use 
gmxdump to read the data. My question is: whether the gmxdump's data is 
reliable or not?
The error message from gmxcheck is the following:
WARNING: there may be something wrong with energy file ener.edr    
Found: step=0, nre=0, ndisre=0, nblock=0, time=0.
