[Pvfs2-users] Re: seqfault on "cp" when using pvfs2's kernel module

[Murali Vilayannur]

Matt,
Turns out that the cp segmentation fault is also related to the coreutils
brain-damage on Mandriva..
It is fixed if you do a cp --attributes=- /mnt/pvfs2/A /mnt/pvfs2/B
Strace log shows what happens when you do a cp from pvfs2 to pvfs2...
gdb'ing cp could pin point why it crashes.. In any case, this is
definitely not a pvfs2 bug (more of a coreutils bug/misfeature?)
Hope everything works out ok for you henceforth..Thanks again for giving
me access to the machines! It was a real help pinpointing the problems.
Thanks,
Murali
