And I ded pvscan and vgchange. pvscan PV /dev/hdb VG vg1 lvm2 [115.04 GB / 75.04 GB free] Total: 1 [115.04 GB] / in use: 1 [115.04 GB] / in no VG: 0 [0 ]
vgchange -ay 1 logical volume(s) in volume group "vg1" now active Thank you for your advice. Now, I can mount on LV. Perhaps, I created the LV by doing... # pvcreate /dev/hdb1; # vgcreate vg1 /dev/hdb; Is it the cause of the probrem? Or when I create LV with lvm2 at the other machine, must I do "dd if=/dev/zero of=/dev/hdb bs=512 count=1"? ========================================================= Matsu e-mail : [EMAIL PROTECTED] ========================================================= -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
