Hi Nathan, Thanks for the reply. Yes, it should have said "directory". You're going to have help me out a bit as I don't understand what you're asking for re. "stat <path-to-volume>/cghbck". I do not see a OS stat command, there is a programmable stat (5) but I'm not a programmer that would know how to use it. Are you asking for the path to the disk or the VG ID? The path to the disk in both LVM v1 & v2 is the same LUN H/W Path 64000/0xfa00/0x22 I think the VG ID you're looking for and it is quite different.
LVM 1: # cat /cghbck/disk35.map VGID 792e94cf50649f50 LVM 2.2: # cat /cghbck/disk35.map2 MAPFILE02 VGID A0000000000000017Fri Sep 28 02:40:28 2012792e94cf-f555-11dd-b66b-e1cbc018d4fd I obtained this info by vgexport to a map file. I know for LVM 1 the VG ID hex first 8 = machine ID (uname -i) and the 2nd 8 hex is time stamp. For LVM 2 I do not know the format, still researching. I did fine this info that may be helpful. In volume groups version 1.0, LVM metadata is required to fit into a single physical extent. In volume groups version 2.0 and higher, metadata is not restricted to an extent. So I'm assuming GNU Tar doesn't know how to handle the HP-UX LVM 2.2 metadata since it is not restricted to a single extent. Would that be a fair assumption? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Nathan Stratton Treadway Sent: Thursday, September 27, 2012 4:49 PM To: [email protected] Subject: Re: [Bug-tar] Issue with GNU Tar and HP-UX LVM v2.2 filesystems On Thu, Sep 27, 2012 at 20:05:38 +0000, Michael White wrote: > I got the tar-snapshot-edit utility and it calls out this file system. > > Director: /cghbck > Dev value too high: "18446744071562076161" > > 4294967295 (I assume this is a cut-and-paste error and the actual output said "Directory:") > 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.

I don't know anything about HP-UX LVM devices specifically, but it might provide some useful information to know what "stat <path-to-volume>/cghbck" reports (for both LVM type 1 and type 2.2 volumes).
