RES: RES: Bug on cp

Hello David!
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 didnĀ“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.

Sure thing!

% 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
% another.
% !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

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
