Tar / fbackup commands

[Dirk De Meyer_3]

Hello,

I've a problem using a tar or fbackup command when creating a backup file on disk. When using tape, it works fine but when I ask to store the backup in a file (tar cf ...), it starts but stops at +/- 2.14 GB and asks a new device. Same result when using fbackup.
Thanks for any reaction.

Is largefile option supported for the file system where you are taking backup?

Check the same with

# fstyp -v /dev/my/rmylvol

The f_flag field must equal 16

The filesystem is probably not mounted with the largefiles option. Usually, this is a good idea for the root file system.

Check the mount options for the filesystem that you are placing the backup file in.

Hi,

Could you check if the largefiles option is enabled on the filesystem ?

online JFS
/root# fsadm /app/oracle/admin
nomultifsets
largefiles

non online JFS

/root# fsadm /dev/vg01/rlvol4
nomultifsets
largefiles

Regards,
Robert-Jan

What os? Tar on pre-11.11 (unpatched) does not archive files that are greater than 2 gig.

Starting at 11.11 tar can handle up to 8 gig with the tar patch (or greater)

fbackup will handle largefiles. So there might be a problem with ulimit or the filesystem. Having the specific fbackup error will help troubleshoot the issue.

Thanks for your reaction. I've noticed that the file system is not mounted with the option largefiles. I've changed this and normally after a reboot (this evening) it will work.

Hopefully, the largefiles option helped.

If the answers to your questions helped, please assign points.
