Hi, I have an LVM system with several Linux installations on it across a large number of logical volumes, within a single volume group, called VG, on a single partition, /dev/hda1, which takes up the whole disk. The metadata flavour is reported as lvm1. I can no longer use 2.4 series kernels with this volume group, only 2.6 series kernels, though I used to be able to use either. What seems to have changed is that I performed an lvextend or lvcreate operation (or lvremove?) under 2.6. Since then, no 2.4 kernel has been able to access the volume group. 2.6 kernels can access it fine. I seem to have two sets of tools installed, which Debian calls lvm10 and lvm2, and am pretty sure that the only ones I have been using are the lvm2 set. Has anyone any idea how I can repair my system so that 2.4 can see it again? Cheers, Mk Here's the output of the system under Knoppix's 2.4.20 kernel: root@tty1[etc]# pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/hda1" is associated to unknown VG "VG" (run vgscan) pvscan -- total: 1 [34.47 GB] / in use: 1 [34.47 GB] / in no VG: 0 [0] root@tty1[etc]# vgscan -v vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d" vgscan -- creating empty "/etc/lvmtab" and "/etc/lvmtab.d" vgscan -- reading all physical volumes (this may take a while...) vgscan -- scanning for all active volume group(s) first vgscan -- reading data of volume group "VG" from physical volume(s) vgscan -- found inactive volume group "VG" vgscan -- getting block device numbers for logical volumes vgscan -- checking block device numbers of logical volumes vgscan -- inserting "VG" into lvmtab vgscan -- backing up volume group "VG" vgscan -- checking volume group name "VG" vgscan -- checking volume group consistency of "VG" vgscan -- ERROR "pv_check_consistency_all_pv(): PE" volume group "VG" is inconsistent vgscan -- ERROR: unable to do a backup of volume group "VG" vgscan -- ERROR "lvm_tab_vg_remove(): unlink" removing volume group "VG" from "/etc/lvmtab" vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group _______________________________________________ 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/
