[Bug-tar] Issue with GNU Tar and HP-UX LVM v2.2 filesystems

[Michael White]

Hello,

 

I am trying to get GNU Tar to do incremental backups and am running into a hard error.  I’ve been using GNU Tar on my HP-UX systems for quite a while but I’ve only been doing full backups but they are taking too long (6 hrs) and incremental would be much better and faster.

The full tar backup runs fine and creates the snapshot file, but when I go to run the incremental I get this error.

 

Unexpected field value in the snapshot file

Error is not recoverable: exiting now

 

I got the tar-snapshot-edit utility and it calls out this file system.

                Dev value too high: “18446744071562076161” > 4294967295

 

From some old posts it appears this may be due to LVM issues so I ran a test and for HP-UX LVM version 1 type volume group the incremental works as advertised.  But when I create a HP-UX LVM 2.2 version volume group I get the above error.

Obviously I’d like to be able to do Tar incrementals on my HP-UX LVM 2.2 version volume groups.

So my questions are: 

Is there a fix hopefully in the works to support incrementals on HP-UX LVM 2.2 version volume groups?

Or is there workaround (other than changing the HP-UX LVM version 1 type volume group?

A HP-UX GNU tar list?

 

Thanks for any assistance anyone can provide.  

If I am on the wrong list I apologize and request pointers to better suited lists.
