After reinstalling Redhat 8.0 on a server system, I am having an odd problem: vgscan recognizes the various VGs on the system, VGsys, VGdata0 and VGdb01. However, LVM seems to confuse VGdata0 and VGsys - "/sbin/vgdisplay VGdata0" produces a VGdisplay for VGsys and "/sbin/lvscan" shows duplicate information for VGsys. As shown below, "/sbin/vgdisplay -D VGdata0" shows the correct information for VGdata0. I am thinking of booting to the Redhat 8.0 installer's rescue mode , vgexport-ing VGdata0, reboot to the system and "vgimport"-ing VGdata0 (and its PVs). Is this likely to solve the problem (I half-expect that all that vgexport does is remove the VG config from the "old" system in preparation for moving the volume, so I'm not sure this will do me any good.) The system runs RedHat Linux 8.0 with the latest updates, and the 2.4.21 kernel with xfs patches (LVM userspace has been updated to redhat/contribs/libc6/SRPMS/lvm-1.0.5-1.src.rpm rebuilt on this system). Hardware is Supermicro Super8050 AIC79XX (onboard u160, connects VGsys) DAC960 (Acceleraid 352, connects VGdata0) aacraid (Adaptec 2200s, connects VGdb01) One thing to note is that one of the PVs in VGdata0 is a whole (HW RAID-5 logical) disk. Listed below are output from: /sbin/vgdisplay -D VGdata0 /sbin/vgdisplay VGdata0 and /sbin/pvdisplay Thanks for the help, Murthy # /sbin/vgdisplay -D VGdata0 --- Volume group --- VG Name VGdata0 VG Access read/write VG Status NOT available/resizable VG # 0 MAX LV 256 Cur LV 3 Open LV 0 MAX LV Size 2 TB Max PV 256 Cur PV 2 Act PV 2 VG Size 266.16 GB PE Size 32 MB Total PE 8517 Alloc PE / Size 5185 / 162.03 GB Free PE / Size 3332 / 104.12 GB VG UUID QmFOyx-ILlI-uNTb-z4hG-ZDnD-kL3Q-UyJGEZ # /sbin/vgdisplay VGdata0 --- Volume group --- VG Name VGsys VG Access read/write VG Status available/resizable VG # 0 MAX LV 256 Cur LV 4 Open LV 4 MAX LV Size 255.99 GB Max PV 256 Cur PV 1 Act PV 1 VG Size 31.65 GB PE Size 4 MB Total PE 8103 Alloc PE / Size 8103 / 31.65 GB Free PE / Size 0 / 0 VG UUID DWvjLY-tFNc-cxXU-epjF-vaEx-uEAA-IM3CtK # /sbin/lvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/rd/c0d0p4" of VG "VGdata0" [129.38 GB / 104.12 GB free] pvscan -- inactive PV "/dev/rd/c0d1" of VG "VGdata0" [136.78 GB / 0 free] pvscan -- ACTIVE PV "/dev/md2" of VG "VGsys" [31.65 GB / 0 free] pvscan -- ACTIVE PV "/dev/sdc1" of VG "VGdb01" [67.75 GB / 0 free] pvscan -- ACTIVE PV "/dev/sdd1" of VG "VGdb01" [271.12 GB / 0 free] pvscan -- total: 5 [636.88 GB] / in use: 5 [636.88 GB] / in no VG: 0 [0] _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
