AIX 5.2 Max File Size

[Mag0007]

I just created a new LV and then a Filesystem (JFS) of 50 gigs. But an Oracle database dump is failing after 2.0 gigs, not sure why...

Anyone else experience this?

BTW, the user oracle has files over 40 gigs on various filesystems.

This is probably a stretch, but could you be hitting a "ulimit" boundary?

Your filesystem is probably not large file enabled
you have to change your filesystem -> set large file enabled to true

What are you using to dump the files? Some utilities aren't largefile aware. That said, my money's on RBBelgium's solution.

RMGBELGIUM:

DO I have to unmount the filesystem first?

Can you dump the file in binary? I know old progress database s have a 2GB dump size limit ( even in JFS with large files enabled ), but if you dump the file in binary it will span to multiple dump files.

Any of the above mentioned posts could be correct as well.

You could start by verify you can create a file larger than 2 GB in the FileSystem you are trying to write the dump too. If you can create a 3 GB file, then it's the dump utility, not FileSystem or the ulimit.

I did a dd if=/dev/zero of=out and it did this

dd if=/dev/zero of=zero
dd: 0511-065 Requested a write of 512 bytes, but wrote only 511.

I tried enabling large support but smitty won't let me...
However, there are other filesystems that are large file enabled.

I had an option of removing the filesystem so I did this.

rmfs /filesystem
mklv -y lv_dbdump -t jfs2 oraclevg 800
crfs -v jfs -d'lv_dbdump' -m'/dbdump' -A 'yes' -a bf=true
