LVM version: 2.00.08 (2003-11-14) Library version: 1.00.07-ioctl (2003-11-21) Driver version: 4.0.0 I am using linux kernel 2.6.3 For making my data can balance on all of my three scsi disk, I use such methods to create my LV: lvcreate -l 32 -n test vg /dev/sda1 lvextend -l +32 /dev/vg/test /dev/sdb1 lvextend -l +32 /dev/vg/test /dev/sdc1 lvextend -l +32 /dev/vg/test /dev/sda1 ...... (I use a shell script to do these) But When I extend a Logic Volumn to 26.5G, it saids: .... Logical volume boards successfully resized Extending logical volume boards to 26.75 GB VG amd64 metadata writing failed Extending logical volume boards to 26.75 GB (lvextend using sdb1 and sdc1 will fail, but lvextend using sda1 will sucess) It is strange I have three scsi disk which are the same. vgdisplay --- Volume group --- VG Name amd64 System ID Format lvm2 Metadata Areas 3 Metadata Sequence No 1585 VG Access read/write VG Status resizable MAX LV 255 Cur LV 8 Open LV 0 Max PV 255 Cur PV 3 Act PV 3 VG Size 102.54 GB PE Size 4.00 MB Total PE 26250 Alloc PE / Size 20032 / 78.25 GB Free PE / Size 6218 / 24.29 GB VG UUID RSR1JG-3vRE-4esH-m8dI-rY4B-WG0p-XweADh pvdisplay /dev/sda1 --- Physical volume --- PV Name /dev/sda1 VG Name amd64 PV Size 34.18 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 8750 Free PE 2286 Allocated PE 6464 PV UUID YAKwOe-oJlA-CbzF-5IwO-ReqH-JZiw-LdhtT7 pvdisplay /dev/sdb1 --- Physical volume --- PV Name /dev/sdb1 VG Name amd64 PV Size 34.18 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 8750 Free PE 1966 Allocated PE 6784 PV UUID FkVeuL-7JAW-UurK-GFcZ-e642-inMT-5MYYMq pvdisplay /dev/sdc1 --- Physical volume --- PV Name /dev/sdc1 VG Name amd64 PV Size 34.18 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 8750 Free PE 1966 Allocated PE 6784 PV UUID sRSor7-r4KP-1PNr-nESn-sZPS-aKMx-7s3CU _______________________________________________ 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/
