How do I debug a GFS/GFS2 performance problem?

Updated 2014-03-11T18:12:04+00:00

Issue

  • Write performance of GFS is extremely slow
  • How can I tell if a task is stuck or just slow?
  • How do I tell which inode is contended?
  • Why does gfs2_quotad appear stuck?
  • What is the maximum throughput of GFS/GFS2 on my hardware?
  • How do I set up email or web servers on clustered file systems?

Environment

  • Red Hat Cluster Suite 4+ with GFS
  • Red Hat Enterprise Linux Advanced Platform
  • Red Hat Enterprise Linux 5 (with the Resilient Storage Add On)
  • Red Hat Enterprise Linux 6 (with the Resilient Storage Add On)
