large files

[Fadia Almarei]

Dear All

I want to do backup for large file (> 2GB) using tar, I install the patch that support large files(PHCO_32438),but the backup did not suceed,what could be the reason for this,and how to solve this.

BR,

Shalom Fadia,

Its probably the filesystem you are making the tar on.

fsadm can be used to convert the filesystem to largefiles.

If you are 11.00 or below you need to mount a filesystem formatted with largefiles with the largefiles parameter in fstab. This requirement was dropped in 11i v1.

If you can do the filesystem over, umount it and use newfs -F vxfs -o largefiles /dev/rlvol6 to in an example do a new filesystem with largefiles.

WARNING: last command is destructive of data.

my system is hp-ux 11.11,and the file system I do the backup from is the /home/oracle.

Hi,

Does your Filesystem support largefiles:
fsadm /home/oracle

If not, do the following:
fsadm -F vxfs -o largefiles /home/oracle
for more info do a man fsadm_vxfs.

Goodluck

Are you trying to backup files larger than 8GB; that is the limit even with the non-standard, patched version of tar.

[Jan de Haas_3]

Don't forget to mount the filesystem with the 'largefiles' option as well.

You can check with what options the filesystem was created using :
mkfs -m

I do the backup for this large file on a tape, but it does not work

Hi,

What is the size of the file? And what is the error you are getting?

Even with patch the tar will be limited to a file size of 8gb.

it is 2306875392 byte,and when I try to do the backup for it,it gives me

tar: Size of ard01.dbf > 2GB. Not dumped.

Hi,

There are a few other options as well to be used for this problem. Find these in this thread

Even after the patch installation if this is the error then possibally the patch was not installed properly or could have been corrupted filesets. A close look at the patch installation logs would halp in finding the real issue.
