[Linux-cluster] GFS2 write

I was trying to copy a 400 GB file to a gfs2 share. It was copying at
50MB/s approx. Suddenly after copying 80% ,the rate dropped to 30KB/s
and stayed like that. I tried to kill the process but could't (which
is normal) and after few minutes it was killed. Then I tried it again
after few minutes and it was successfully copied at 50MB/s. But  then
after it looks like accessing the GFS share (even ls -l /gfsmount)
takes 10-15 seconds to complete. Then I rebooted this node and
everything is back normal.

I am really confused what has gone wrong. GFS is running with all
default parameters .
