Michael,

When you create a volume in HP-UX it automatically strips off 10% of the disk space, so if you mount up 200GB you get 180GB of usable space. On top of that running beyond 95% of usable is not recommended though it will work. These restrictions have been around for quite a long time and I abide by them. I've seen data files get corrupted when you push a filesystem up to and/or beyond 100% of usable.

Subject: OmniBack and HP-UX

This was a new one for me.

I'm having a database restored using the "latest" and greatest, with SAN, and Omniback, and putting it on a different server.

Some of my disks were "full", some pretty close which has never been a problem before, but usually I work on Solaris.

HP-UX choked on several of the volumes and the "early" reports are saying that either OmniBack or the HP-UX does not want or will not write a full volume back on "restore". This could be quite serious.

They are recommending 10%, but some of the volumes are 200+GB and I can't imagine having to hold back 20gb so I can restore some time down the road.

Anyone else get caught with this?
