hello all,
I m using pvfs.2-8-1. I have 1 I/O server and 2 metadata servers using
replication. I am on User mode. When i run pvfs2-cp it returns a segmentation
fault. The file that i am trying to cp is copied successfully. After using gdb
here is what i get:
[Thread debugging using libthread_db enabled][New Thread 0xb7ef56c0 (LWP 31833)]

It get a segfault in file sys-io.sm, function :unstuff_neededwhen trying to
execute: first_unstuffed_offset = dist_p->methods->next_mapped_offset(
dist_p->params, &fake_file_data, 0);
Any help or information about what is causing this would be great.
