Free Physical Extents' count in volume group

[chad_c]

receiving the following error in our HPOV Java GUI

The error is from one of our HPUX 11.11 boxes. Can anyone shed some light on this:

"Free Physical Extents' count in volume group /dev/vg00 has fallen below 200."

Regards,
Chad

It means just what it says: That you have less than 200 free extents left in your volume group.

Chad,

Agree with the above answer, just an informational message. This message is produced due to the important nature of vg00, if it gets full then nothing is going to work and most likely this is why HPOV is taking its time to let you know the size.

Regards,

Jaime.

If you do a 'vgdisplay vg00' and look at the line 'FREE PE' you will probably see that it is less than 200.

What does this mean? It means you can increase any LV's in VG00 by the number of PE's available. Now if your VG00 is mirrored, which it should be, then you can only increase your LV's by 'FREE PE / 2' since the primary and the mirror use a PE.

To see if you are mirrored you need to do an lvdisplay on each LV and look at the 'MIRROR COPIES' line. If it is greater than 0 then you are mirrored.

The 'FREE PE' has nothing to do with the any VG00 file systems "getting full". This is COMPLETELY DIFFERENT than a full file system. If you have 'FREE PE' equal to 0, your system will run just fine, but you have no room to expand any VG00 LV's.
