Daniel,

    What do you have on db_file_multiblock_read_count on the problem database?

Regards,
Luis

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
