CPIO error 27 - File too large

Subject: CPIO error 27 - File too large

When I do a backup "find / -o -print | cpio -ocv -O /file_system_in_AIX" in a NFS mounted on AIX system appears the error:


cpio: I/O error on write() : File too large (error 27)

The AIX file System is created for big files


Hate these ads?

As I can solve it?

SCO OpenServer 5.0.6

NFS isn't AIX. You have a (N)etwork (F)ile (S)ystem that happens to have an AIX file system under it.



NFS V2 only supports up to 2GB. NFS V3 supports more.

SCO 5.0.6 uses V2, Openserver 6 uses V3. I have no idea what your AIX uses, and I don't know what happens when a V2 client mounts a V3 server. However, the answer is going to be on the AIX side, not on the SCO, because 5.0.6 only has V2.

I did find this from http://www.unet.univie.ac.at/aix/aixbman/commadmn/nfs_intro.htm 

 

The file size limit for files located on an NFS server is taken
from the process environment when nfsd is started. To use a specific
value, edit the file /etc/rc.nfs and add a ulimit, using the ulimit
command, with the desired limit before the startsrc command for
nfsd.


but again I'm unclear on exactly how NFS V3 interacts with V2.

Oh, and of course cpio itself is running on OSR5.0.6 so it may be IT that can't handle the offset - in fact, that's probably the issue.

I seem to recall that last time I tried this (1988?) the problem with moving cpio *tapes* between systems was the little endian/big endian problem. There was a switch in AIX's cpio that let me make a tape that could be read on ATT a SVR4 system (50MHz 486 IIRC).

In my case, the applied solution is:


cd /
tar cvf - . | rcmd address_of_remote_system "dd of=remote_device"

The speed is very, very best and no have the problem 'file too large'
