[Ocfs2-users] Linux-x86_64 Error: 4: Interrupted system call

[Daniel Keisling]

Greetings,
 
When attempting to start up a database on an OCFS2 filesystem, Oracle
complains with the following errors:
 
 
ORA-27090: Message 27090 not found;  product=RDBMS; facility=ORA
Linux-x86_64 Error: 4: Interrupted system call
Additional information: 3
Additional information: 128
Additional information: 65536
*** 2008-08-12 14:02:01.304
Warning: OS async I/O limit 128 is lower than recovery batch 1024
 
 
Searching for 'interrupted system call" seems to suggest that filesystem
is not mounted with the nointr option, but it is:
 
/dev/sdg1 on /var/opt/oracle/oradata/ph1p type ocfs2
(rw,_netdev,datavolume,nointr,heartbeat=local)
 
 
I have no idea about the async I/O limit.  I know that this kernel
paramater is no longer tunable in 2.6 kernels.
 
I have a dozen or so databases on another filesystems and on other
machines, none of which exhibit this behavior.  Does anyone know why it
complains of an 'interrupted system call' and I/O limits for this
filesystem and/or if they pose a problem?
 
Kernel is 2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:19 EDT 2007 x86_64
x86_64 x86_64 GNU/Linux
Under Red Hat v5.1 with ocfs2-2.6.18-53.el5-1.2.8-2.el5.
 
TIA,
 
Daniel
