We have a 2 node cluster, with qlogic san drives and GFS filesystem.
When the system boot we get a message in dmesg:

The last line we see in messages when both systems read from the GFS filesystem, the read performance is very low on that moment.
We are using linuxrdac-09.01.B5.30
Any has a solution?
