I got a knoppix rescue cd with lvm version 1.0.8 running now and a sshd server to rescue my data. Problem is that this version is not compatible with my volume group: vgscan: 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 "vg01" from physical volume(s) vgscan -- found inactive volume group "vg01" vgscan -- getting block device numbers for logical volumes vgscan -- checking block device numbers of logical volumes vgscan -- inserting "vg01" into lvmtab vgscan -- backing up volume group "vg01" vgscan -- checking volume group name "vg01" vgscan -- checking volume group consistency of "vg01" vgscan -- checking existence of "/etc/lvmtab.d" vgscan -- storing volume group data of "vg01" in "/etc/lvmtab.d/vg01.tmp" vgscan -- storing physical volume data of "vg01" in "/etc/lvmtab.d/vg01.tmp" vgscan -- storing logical volume data of volume group "vg01" in "/etc/lvmtab.d/vg01.tmp" vgscan -- ERROR 2 writing volume group backup file /etc/lvmtab.d/vg01.tmp in vg_cfgbackup.c [line 271] vgscan -- ERROR: unable to do a backup of volume group "vg01" vgscan -- ERROR "lvm_tab_vg_remove(): unlink" removing volume group "vg01" 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 the error looks the same so I assume that something is incompatible in my old system. I never changed lvm version as far as I know of... but it might be possible. Is there a way to access this volume group now? Any help is really appreciated.
