RES: RES: Bug on cp
Tue, 31 Dec 2002 09:10:53 -0200
I have RAID 0+1.
How can I see the inodes and increase them ?
Yes, I am going from ext2 to ext2.
Last night I follow the steps from backup and I think because we didn´t run
a update procedure , the datafiles were not accessed and the backup finished
succesfull, but the messages :
Dec 31 01:00:22 dtmart kernel: __alloc_pages: 0-order allocation failed.
Dec 31 01:00:40 dtmart last message repeated 826 times
Dec 31 01:00:40 dtmart kernel: failed.
still appear on my /var/log/messages.
During the cp process the top command showed me that the kswapd and bdflush
cp were consuming a lot of CPU.
Do you know if my kernel parameters were well tuned for these copy process ?
# Disables packet forwarding
net.ipv4.ip_forward = 0
# Enables source route verification
net.ipv4.conf.all.rp_filter = 1
# Disables the magic-sysrq key
kernel.sysrq = 0

Thanks again and happy new year !!!

% Thanks for the answer.
% The machine hangs and I can not login , I have to turn the power off.
Hmmm... You should log in before it gets into trouble :-)
% No, I have a lot of disk space.
Good. RAID? SCSI? IDE?
Oh, hey, what about free inodes? 2G needs a bunch of pointers...
% The file has 2GB.
% The filesystem is ext2.
Well, 2G is the ext2 limit, but you're probably going from ext2 to ext2
and so it's probably the 2G - 1 that it must be to fit.
% Yes, I am crossing filesystems./ora_siopsix is one filesystem e /staging
% ALTER TABLESPACE "SIOPSIX" BEGIN BACKUP;
% !cp "/ora_siopsix/siopsixdtma.ora" /staging
% !cp "/ora_siopsix/siopsix4dtma.ora" /staging
% !cp "/ora_siopsix/siopsix3dtma.ora" /staging
% !cp "/ora_siopsix/siopsix2dtma.ora" /staging
% !cp "/ora_siopsix/siopsix1dtma.ora" /staging
% ALTER TABLESPACE "SIOPSIX" END BACKUP;
What if you just try one -- each one by itself to test? Does it fail for
any particular one, or always the first, or only when you try more than
one or all, or ...?
% The copy does not involve network.
% I can not login to the machine and use top.
% I can not login to use strace.
If you can't log in at all (before there's a problem), it will be
extremely difficult to debug this. If that's the case, talk to your
SysAdmin (who may have some ideas himself or herself) and get a login
account for this work.
% Thank you very much
