Wrong display in bdf

Daniel Schneider_3 — Thu, 04 Sep 2003 10:39:54 GMT

Hi all,

who can tell me, why bdf and df shows wrong entries?:
/data (/dev/vg00/data ) :
1018213 total allocated Kb
87778 free allocated Kb
930435 used allocated Kb
91 % allocation used

The 'used' - Value is correct, but not the 'free' - Value. Why?

uname -a:
HP-UX hp-baan B.11.11 U 9000/800 146271751 unlimited-user license

Thanks for all help

Best Regards
Daniel

Daniel,

Ok - forgotten. But I do have to ask what you're doing with data in vg00. The ideal setup reserves vg00 strictly for the root volume group and keeps all data in other volume groups for ease of backup and recovery.

Daniel,

It gets involved. Do you have spare disk space? Unallocated disk space? Room in another volume group?

The general idea is to copy the data from one location to the other. The method can be: a straight copy; a backup/restore operation; or some kind of mirroring. It depends on the situation. If this is not a problem for you at the moment, I would just keep this in mind for the future - for the next time you have an opportunity to set up a system.

Is it actually possible to make two VG's on one physical Disk? Because there is only one Hard Disk in the Machine!

In that case, with only one disk, you're stuck with just one volume group so disregard everything I said - you have no choice!

Hi,
just out of curiosity: are you sure you only have one disk? The reason I ask is because your logical volume is mirrored, but it could of course be mirrored on the same disk.. just curious.

John K.

Good point, John! I didn't even notice the mirror. Could you post the output of "ioscan -kfnCdisk", please, Daniel?

Yes, I know, there is the second Hard Disk. But I want it only for Mirror, so when the first Hard Disk is defect, I have it completely mirrored and can boot from the alt bootpath.

Thank you Guys for your help.

Best Regards
Daniel

You're the boss, Daniel. In order to be a mirror, it has to be part of the same VG anyway, so we're right back where we started.
