A data processing server uses a Linux based file system to remotely mount physical disks on a
shared SAN. The server administrator reports problems related to processing of files where the file
appears to be incompletely written to the disk. The network administration team has conducted a
thorough review of all network infrastructure and devices and found everything running at optimal
performance. Other SAN customers are unaffected. The data being processed consists of millions
of small files being written to disk from a network source one file at a time. These files are then
accessed by a local Java program for processing before being transferred over the network to a
SE Linux host for processing. Which of the following is the MOST likely cause of the processing
problem?
A.
The administrator has a PERL script running which disrupts the NIC by restarting the CRON
process every 65 seconds.
B.
The Java developers accounted for network latency only for the read portion of the processing
and not the write process.
C.
The virtual file system on the SAN is experiencing a race condition between the reads and
writes of network files.
D.
The Linux file system in use cannot write files as fast as they can be read by the Java program
resulting in the errors.
