0516-018 lcreatelv error 2

[gatetec]

I am getting this error:

mklv -y 'dtrain1_0000126' -w n -t 'raw' train1vg 1 hdisk15
0516-018 lcreatelv: No more logical volumes can be created; the maximum number has been reached. Use a different volume group. 0516-822 mklv: Unable to create logical volume.

The number of LVs are below 256, but I tried to change the MAX LVs to 512, which returns:

0516-1616 chvg: This operation is only valid for scalable volume groups.
0516-732 chvg: Unable to change volume group train1vg.

What is the issue and the fix?

thx much

I'm guessing the VG keeps one slot in the LV table to create a log-lv for filesystems?

As you have plain-old 32-PV VG, the operation to increase max LVs is not valid. That is only for Scalable VGs.

What is stopping you from creating another VG and continuing your LV creation there?


HTH,

Ermm... You've hit the limit of 255 LVs. Please post `lsvg -l train1vg`

I think you can convert a VG to be scalable. Never done it though

Thanks much, I got it now.

chvg -B takes care of the issue for me.

thx much
