[Linux-cluster] GFS Performance

[Richard Mayhew]

Hi


I setup 2 nodes, on my EMC SAN. Both nodes see the storage and can
access the cca device.
When writing a file to the storage fs, the second node takes a couple of
seconds to see the changes.

Ie. 
1. Node 1 Creates the file "dd if=/dev/zero of=test.file bs=4096
count=10240000"
2. Doing a ls -la on node 2 takes a few seconds to display the contents
of the dir.

After the file has finished being updates, all listings of that dir are
quick, but if any changes are made, one again has to wait for the system
to display the contents of the dir.

Any idea?
