lvcreate problem

Dario_4 — Fri, 13 Sep 2002 16:41:32 GMT

Hello,

here's my script:

for i in 191 192 193 194 195 196 197 198 199 200
do
lvcreate -n lv_ict_2048_raw_$i -L 2048 -i 4 -I 64 /dev/vg_ict_raw
done

I see:

lvcreate: Unable to generate a name for the logical volume.
Invalid argument
lvcreate: Unable to generate a name for the logical volume.
Invalid argument
lvcreate: Unable to generate a name for the logical volume.

Any idea ?

Hi Dario:

Try a shorter string for your logical volume names.

I ran a short test and I could create a basic lvol with your arguments:

1. confirm you have 4 disks with space in the volume group
2. change the sequence a bit:

lvcreate -L xxxx -i x -I xx -n /dev/vgxx

I can't ...

But it's strange, because till lv_ict_2048_raw_191 it works fine...

The lvcreate syntax is correct. The only thing that I suspect is the LV name that your using. Though I do not know if it has a limit to it but it's very usual to name your LV like that .. "lv_ict_2048_raw_191" and so on. Try to just create the LV with a much simpler name or shorter name, like .. "lvraw191" for example.

if you still get trouble.. test on a simpler string.. create the lvol without any striping using your script... for just one lvol so you don't have to back too many. If you can create the lvol as described with no striping... you at least have something to now look at... there are some comments about using lvcreate if volume group is in shared mode (man pages)

Hi,

I'm curious. When you do a 'vgdisplay /dev/vg_ict_raw', what are the Max LV and Cur LV values?

I try with your syntax:

lvcreate -L 2048 -i 4 -I 64 -n lv_ict_2048_raw_191 /dev/vg_ict_raw

but same result...

I have many.. many lvol names with strings much longer than yours... of course we are running 11.0 and 11i...

try and enclose {} around the i... ${i}.. assuming that you are still trying to make this work and you need the lvols named the way you specified at the top

Max LV 255
Cur LV 255

Argh!! may be the problem is that.. how to solve it ?

Oops. You can't have more than 255 LVs in a VG. Time to create another VG.

By the way, that post from the RC ENGINEER was really me. Something really freaky happened when I logged in and posted a response on this thread. I got logged in as myself now, but that was scary.

Hi:

John P (a.k.a. "the engineer") nailed it. If you have 255 logical volumes in a volume group you are at a limit. You simply cannot create anymore within the volume group!
