[Ocfs-users] Q: Copy/Move of a to OCFS file system causing system hang

[Ramgrid at aol.com]

Greetings,
We were looking for some advise on an OCFS hang: Out of memory error.
We are on red hat version 3 , kernel 2.4.21-27.0.1.ELsmp  and ocfs  1.0.13-1.
 
If we  try to move/copy a 5GB compressed file into a ocfs file system,  the 
command gets killed by kernel after 70% of work with the following log in  
/var/og/messages:
 
Jan 31 16:02:41 conrep-d04 kernel: 4177919 pages of RAM
Jan 31 16:02:41  conrep-d04 kernel: 3817463 pages of HIGHMEM
Jan 31 16:02:41 conrep-d04  kernel: 205990 reserved pages
Jan 31 16:02:41 conrep-d04 kernel: 1146612  pages shared
Jan 31 16:02:41 conrep-d04 kernel: 0 pages swap cached
Jan 31  16:02:41 conrep-d04 kernel: Out of Memory: Killed process 3595 (bash).
Jan 31  16:02:41 conrep-d04 kernel: Out of Memory: Killed process 3595 (bash).
Jan 31  16:02:41 conrep-d04 kernel: Fixed up OOM kill of mm-less task
Jan 31 16:17:04  conrep-d04 syslogd 1.4.1: restart.
 
 
This process has worked for us in development. We have copied 100GB of  files 
in development.
 We are transitioning to production to new HP Linux servers. However,  we are 
stuck with this error. We are waiting on Oracle support tar  4282257.999.
 
Meanwhile, Any advise on what to look for the memory management error. The  
system is idle. the cp or mv is the only command.
 
OCFS details
ocfs partition/fs size 1 TB
number of ocfs partitions/node 25
number of nodes 8
block size 128
 
Is kernel kernel .2.4.21-27.0.1.ELsmp  an issue? Development is on  
2.4.21-27.0.2ELSMP.
 
 
thanks
