[Carme Torca]

Hi,

I would known the number of disk in a lvol with PVG-strict/distributed.
I have one lvol with this option.

And could I change it to add more disks?

Thanks!
Carmen.

lvdisplay -v /dev/vg??/lvol??

you can see all disks that this lvol is on.

lvdisplay -v will provide this and also look at your /etc/fstab to see.

you can try.

- lvdisplay -v /dev/vgxxxx/lvolxx
OR
strings /etc/lvmtab

[Sandman! · Accepted solution]

lvdisplay -v

...will show all the PVs that make up this lvol, and yes you can add more disks to this VG as long as you are not running into one of the LVM limits like...max PVs per VG or max PEs per PV etc.

hope it helps!
