Hi, I have a 8-disk RAID 0 device with 6 partitions and managed under LVM 1.0.3 (RH8, kernel 2.4.18-27.8.0smp): Disk /dev/sda: 255 heads, 63 sectors, 218789 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 36449 292776561 8e Linux LVM /dev/sda2 36450 72898 292776592+ 8e Linux LVM /dev/sda3 72899 109347 292776592+ 8e Linux LVM /dev/sda4 109348 218789 879092865 5 Extended /dev/sda5 109348 145796 292776561 8e Linux LVM /dev/sda6 145797 182245 292776561 8e Linux LVM /dev/sda7 182246 207245 200812468+ 8e Linux LVM The following physical volumes are reported by pvscan: # pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- ACTIVE PV "/dev/sda1" of VG "vgt9" [279.21 GB / 0 free] pvscan -- ACTIVE PV "/dev/sda2" of VG "vgt10" [279.21 GB / 11.98 GB free] pvscan -- ACTIVE PV "/dev/sda3" of VG "vgt9" [279.21 GB / 105.57 GB free] pvscan -- inactive PV "/dev/sda5" of VG "vgt9" [279.21 GB / 279.21 GB free] pvscan -- ACTIVE PV "/dev/sda6" of VG "vgBulyk" [279.19 GB / 0 free] pvscan -- ACTIVE PV "/dev/sda7" of VG "vgBulyk" [191.48 GB / 688 MB free] pvscan -- total: 6 [1.55 TB] / in use: 6 [1.55 TB] / in no VG: 0 [0] This setup I inherited from the previous sysadmin, so I don't know the history details, but I assumed /dev/sda5 was never used. Now I want to add it to vgt9 volume group or move it to vgt10 one. This does not work: # vgextend -v vgt9 /dev/sda5 vgextend -- locking logical volume manager vgextend -- checking volume group name "vgt9" vgextend -- checking volume group "vgt9" existence vgextend -- checking for inactivity of volume group vgextend -- reading data of volume group "vgt9" from lvmtab vgextend -- INFO: maximum logical volume size is 255.99 Gigabyte vgextend -- reading data for all physical volumes from disk(s) vgextend -- extending VGDA structures of volume group "vgt9" vgextend -- ERROR: "/dev/sda5" is not a new physical volume # vgreduce vgt9 /dev/sda5 vgreduce -- physical volume "/dev/sda5" doesn't belong to volume group "vgt9" # vgextend vgt10 /dev/sda5 vgextend -- INFO: maximum logical volume size is 255.99 Gigabyte vgextend -- ERROR: "/dev/sda5" is not a new physical volume However: # pvdisplay /dev/sda5 --- Physical volume --- PV Name /dev/sda5 VG Name vgt9 PV Size 279.21 GB [585553122 secs] / NOT usable 4.44 MB [LVM: 407 KB] PV# 3 PV Status NOT available Allocatable yes Cur LV 0 PE Size (KByte) 4096 Total PE 71477 Free PE 71477 Allocated PE 0 PV UUID YXRHyO-Ykl0-t7v1-iesS-WjJs-EadK-XRYQQY Am I doing something wrong? What else to try?
