Troubleshooting
Problem
A specific volume move always fails at a specific byte size of 1073741312 bytes.
Resolving The Problem
Any UNIX OS sees AFS volumes as individual files. Looking at specific OS kernel parameters, we found that the fsize parameter in the /etc/security/limits file on the receiving fileserver was set at 2097151 blocks. These blocks were set at 512 bytes each. Performing the math we found that 2097151 x 512 = 1073741312, or the exact byte size at which the volume moves would fail. A reset of the fsize parameter in the /etc/security/limits file to a value of "-1" (essentially "unlimited") and a reboot is necessary to resolve this.
