[Ocfs2-users] slow file creation

[Matthew Flusche]

Hi all,
 
I'm troubleshooting an ocfs2 performance problem where creating files in
a directory containing ~180k files is taking significant time to
complete.  Sometimes creating an empty file will take >100 seconds to
complete.  This is a three node cluster.  I'm currently running OCFS2
1.2.3-1.  Are there any changes in a recent version that may address
this issue?  What should I look at to troubleshoot?  The systems overall
utilization is low.
 
(All 3 systems are identical)
RHEL 4 update 4 - 2.6.9-42.0.2.ELhugemem (32-bit)
ocfs2-2.6.9-42.0.2.ELhugemem-1.2.3-1
ocfs2-tools-1.2.2-1
 
HP Proliant DL385 - 2 X 2.4 GHz AMD Opteron Processor 250
16GB RAM
2 X emulex LP10000 HBAs
Powerpath 4.5.1
 
shared disks are from an EMC clariion CX500
 
 
Thanks,
 
Matt
