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

This may not be related to ocfs2. Check the oracle doc for the version of the database you are running. It will have all the appropriate kernel settings.

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,
