Hello,
I have 4 GFS volumes, each 4 TB. I am seeing pretty high load
averages on the host that is serving these volumes out via NFS. I
notice that gfs_scand, dlm_recv, and dlm_scand are running with high
CPU%. I truly believe the box is I/O bound due to high awaits but
trying to dig into root cause. 99% of the activity on these volumes
is write. The number of files is around 15 million per TB. Given
the high number of writes, increasing scand_secs will not help. Any
other optimizations I can do?
Thanks!
