[PVFS-users] PVFS error at client side

[Tajendra Vir Singh]

Hello,

We are in testing mode for a pvfs system on our beowulf cluster. 
Yesterday I was trying to run the perf.c code using 2 nodes (dual cpu 
each) with SIZE parameter 1048576*640. That means from four cpus the 
total file size would have been 2684354560.

When I started running the code, the client from which I started it 
stopped doing any activity to /pvfs file system. I had to kill the run 
as I suspected it was hanging. Even ls on /pvfs just hanged after words.

The following are the message in the system's log at client side. The 
metaserver and ionodes were working properly even after this happened. 
The /pvfs was still mounted on other client properly and /pvfs was 
accessable through them.

Any clue as to why it happened will be highly appreciated.

Thanks in advance,

TV
