I have found a couple of times in testing that lvs will sometimes report the same logical volume 2 or more times when output options are used. It seems to happen with volumes that are a large percentage of the total group size. Below I give an example. Notice how "lvs" with no options works fine but with options doesn't. ~/benscott/myprog# vgs VG #PV #LV #SN Attr VSize VFree test2 4 6 0 wz--n- 14.29G 328.00M vg1 2 1 0 wz--n- 147.18G 1.18G ~/benscott/myprog# lvs LV VG Attr LSize Origin Snap% Move Log Copy% bigtest1 test2 -wi-a- 900.00M bigtest2 test2 -wi-a- 100.00M bigtest3 test2 -wi-a- 1000.00M bigtest4 test2 -wi-a- 1.27G bigtest5 test2 -wi-a- 1000.00M bigtest6 test2 -wi-a- 9.77G lv1 vg1 -wi-ao 146.00G ~/benscott/myprog# lvs -o +stripes,stripesize LV VG Attr LSize Origin Snap% Move Log Copy% #Str Stripe bigtest1 test2 -wi-a- 900.00M 1 0 bigtest2 test2 -wi-a- 100.00M 1 0 bigtest3 test2 -wi-a- 1000.00M 1 0 bigtest4 test2 -wi-a- 1.27G 1 0 bigtest5 test2 -wi-a- 1000.00M 1 0 bigtest6 test2 -wi-a- 9.77G 1 0 bigtest6 test2 -wi-a- 9.77G 1 0 bigtest6 test2 -wi-a- 9.77G 1 0 bigtest6 test2 -wi-a- 9.77G 1 0 lv1 vg1 -wi-ao 146.00G 2 32.00K # lvs --version LVM version: 2.02.07 (2006-07-17) Library version: 1.02.12 (2006-10-13) Driver version: 4.7.0 These are the physical volumes involved: /dev/hdh1 test2 lvm2 a- 952.00M 328.00M /dev/hdh2 test2 lvm2 a- 1.39G 0 /dev/hdh5 test2 lvm2 a- 7.18G 0 /dev/hdh6 test2 lvm2 a- 4.79G 0 _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
