[linux-lvm] What command do I use to make a PV active?

[linux-lvm] What command do I use to make a PV active?

[Greg Freemyer]

 
Somehow I inactived a PV

# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/sda3" of VG "TruStore-Data" [53.63 GB / 48.63 GB free]
pvscan -- ACTIVE   PV "/dev/sdb1" of VG "TruStore-Data" [74.54 GB / 13.54 GB free]
pvscan -- total: 2 [128.19 GB] / in use: 2 [128.19 GB] / in no VG: 0 [0]

What command do I use to make it active?

Thanks
Greg

Hmm, there's no direct (in)activation of PVs.
A bit strange, that both are in diffrent states (they should be either inactive
in case the VG is or both active in case the VG got activated).

If the VG "TruStore-Data" is inactive, "vgchange -ay TruStore-Data" should turn
/dev/sda3 active as well.

Is "TruStore-Data" accessable fine (LVs ok) ?

This is a lab/test machine.  I have a couple of others that have a
similar LVM layout, and all of them have hot-swap drives.  I likely
moved a drive around at the wrong time.

It is already active, and I just tried a reboot.  sda3 is still
inactive.

I have 3 LVs on sdb1, they are working fine.

I have a copy of my Linux Distro CDs and spare space for sdb1 snapshots
on sda3.  They are not working.

Obviously I can recreated the CD copies, but I prefer not to do this.

Is there something else I can try?

FYI: None of this data is very important, so I won't complain too loud
if you ask me to do something and it ends up blowing everything away.

Thanks

Ah, the  let me assume, that this is the reason why the inactive status
is stored on the PV.

You might want to create a dummy LV and remove it.
That changes PV state stored on disks.

That did not work.  Apparently the VG did not think sda3 was part of it.

I ended up doing a 'pvcreate -ff /dev/sda3'.

Then a vgextend to re-add it to the VG.

I had to recreate and populate the LV I had on there previously, but it
was not a huge deal.

Thanks for the help.
