Problem with vg01

Dario_4 — Tue, 09 Apr 2002 12:05:52 GMT

Hi alls,
I wuold like to do clear for this thing:
I have 3 vg's (vg00, vg01 and vg02) but, when i type bdf i see only 2 vg's vg00 and vg02.
Why I can't see vg01 ?

Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 143360 49973 87572 36% /
/dev/vg00/lvol1 127573 72176 42639 63% /stand

/dev/vg02/lvolfab 2097152 1614 1964574 0% /home/fab

If I type vgdisplay -v /dev/vg01 I see this:

#vgdisplay -v /dev/vg01
--- Volume groups ---
VG Name /dev/vg01

Autoswitch On

PV Name /dev/dsk/c0t1d0

Which is the problem?

Thanks in advance

Hi:

There are no filesystems associated with vg01 and hence nothing to mount, and therefore nothing for 'bdf' to report.

If you examine the output of your 'lvdisplay -v /dev/vg01' you will note the line "Cur LV 0". This shows the absence of any logical volumes upon which filesystems can be created.

Regards!

looks as if the volume group is unused, create some filesystem on it and they will show up in bdf.

Hi,

Look at:

# strings /etc/lvmtab (is vg01 in there ?)

# more /etc/fstab (is vg01 in there ?)

if both answered yes then do:

# mount -a
# bdf

Now it should be there.

If not in lvmtab then you have to run
# vgscan -v -a

Clemens

Hi,

Both guys are correct.
Overlooked the current LV line.

Sorry for the wrong answer.

bdf shows you only the mounted filesystems defined on the LOGICAL volumes.

In vg01, you have 0 logical volumes (CUR LV=0).
Define some lvol1 and lvol2 on vg01 and mount these, like you did with vg02 and vg00.

In other words, bdf does not give you the full scope of what you have, only the active filesystems mounted.

Ceesjan

Sure, I forget to assign the logical volume.

Sorry for stupid question.

hi,

There doesnt seem to be any problem. the vgdisplay output of vg01 shows that there are no LV's in vg01. You can create LVs under vg01 and mount them as filesystems.

To reconfirm there are no lv's do:
ll /dev/vg01
strings /etc/lvmtab | grep vg01

Hi,
looking from your vg01 information . You can see that the allocated PVs are 0 hence no file systems associated with that vg. In fact you are not using that vg at all. You just created it that's it.
