I have spent some time looking at this problem and it seems the issue is that 
the TS-7370 uses a jfs file system and CentOS does not support jfs unless you 
load the CentOSPlus kernel which creates issues of its own. (see 
wiki.centos.org/AdditionalResources/Repositories/CentOSPlus)

The grow_sd script does a mount and then tries to determine the file system 
(jfs or ext3), unfortunately it does not check the status of the mount so when 
it fails and then tests the file system it sees the host file system (ext3 in 
the case of CentOS).  That is why that there was a problem was not readily 
apparent when running the grow_sd script.

Using a computer that support jfs and has the jfsutils package seems to work 
fine. Before using the script test if the last partition on the SD card can be 
mounted. If it can the grow_sd will probably work.

dd a good image to the new bigger SD card then....
mkdir /mnt/tmp
mount /dev/sdb4 /mnt/tmp
be sure to umount and remove /mnt/tmp before you run grow_sd
If that works then grow_sd will probably work.

Thanks for all the help
