Hi David,
There are a bunch of #defines that limit the sizes of requests. The PVFS_REQ_LIMIT_CONFIG_FILE_BYTES (defaults to 16384) limits that fs.conf size. Its defined in src/proto/pvfs2-req-proto.h. If you increase that to something larger, you should be able to get past that assertion failure.

I performed a large scale test of pvfs last friday with some very interesting results... I have to pass it though our (PNNL) internal documentation sanitation system but I should be able to give you guys real data from the tests then, but here's what the problems were. ;) The main problems was the meta data server crashes with using 940 data servers, same error with 570 data servers. I ended up using 255 data server nodes and it started working fine.

Aborted [EMAIL PROTECTED] ~]# I'm guessing this is because you load the entire config file when the first data server tries to connect and the config file was just too damn big. Is there a nice define somewhere that I can change to make it be able to load more? The config file ends up being quite large...
