Hello, does anyone of you know, whether it is possible to restore an LVM just from the physical volumes and the VG.conf file ? I did an update from Kernel 2.4.10 (SuSE 7.3) to 2.4.19 (SuSE 8.1) with the result that no volume groups are found :-( My LVM structure is like this: The only volume group is "hxvg01" which contains two volumes "hxlv01" (pv: hdc1, hdd1) and "hxlv02" (pv: hdb1) I tried to use vgcfgrestore (@SuSE 8.1), but it failed with this messages: vgcfgrestore -- INFO: using backup file "/etc/lvmconf/hxvg01.conf" vgcfgrestore -- ERROR: different structure size stored in "/etc/lvmconf/hxvg01.conf" than expected in file vg_cfgrestore.c [line 139] vgcfgrestore -- ERROR "vg_cfgrestore(): read" restoring volume group "hxvg01" Is this the often discussed "compatibility problem" ? How can I safe migrate to the new LVM Version without loosing all my data OR (if it is not possible) how can I access my LVM on a Linux 2.4.10 System ? The vgcfgrestore-step taken on a minimal Linux (SuSE 7.3) with Kernel 2.4.10 shows that following result. Which steps are necessary to access my volumes under Kernel 2.4.10 ? Is it possible to import the VG using the -f parameter of vgimport ? # vgcfgrestore -ll -n hxvg01 -t -v vgcfgrestore -- locking logical volume manager vgcfgrestore -- restoring volume group "hxvg01" from "/etc/lvmconf/hxvg01.conf" vgcfgrestore -- checking existence of "/etc/lvmconf/hxvg01.conf" vgcfgrestore -- reading volume group data for "hxvg01" from "/etc/lvmconf/hxvg01.conf" vgcfgrestore -- reading physical volume data for "hxvg01" from "/etc/lvmconf/hxvg01.conf" vgcfgrestore -- reading logical volume data for "hxvg01" from "/etc/lvmconf/hxvg01.conf" vgcfgrestore -- checking volume group consistency of "hxvg01" vgcfgrestore -- checking volume group consistency of "hxvg01" vgcfgrestore -- backup of volume group "hxvg01" is consistent --- Volume group --- VG Name hxvg01 VG Access read/write VG Status NOT available/resizable VG # 0 MAX LV 256 Cur LV 2 Open LV 0 MAX LV Size 255.99 GB Max PV 256 Cur PV 3 Act PV 3 VG Size 160.53 GB PE Size 4.00 MB Total PE 41096 Alloc PE / Size 41075 / 160.45 GB Free PE / Size 21 / 84.00 MB VG UUID cXz5yh-KTaG-XRxy-v30t-ajxu-dV2W-Bpu1W0 --- Logical volume --- LV Name /dev/hxvg01/hxlv01 VG Name hxvg01 LV Write Access read/write LV Status NOT available LV # 1 # open 0 LV Size 83.85 GB Current LE 21465 Allocated LE 21465 Allocation next free Read ahead sectors 128 Block device 58:0 --- Logical volume --- LV Name /dev/hxvg01/hxlv02 VG Name hxvg01 LV Write Access read/write LV Status NOT available LV # 2 # open 0 LV Size 76.60 GB Current LE 19610 Allocated LE 19610 Allocation next free Read ahead sectors 120 Block device 58:1 --- Physical volume --- PV Name /dev/hdd1 VG Name hxvg01 PV Size 41.93 GB / NOT usable 3.49 MB [LVM: 271.00 KB] PV# 1 PV Status available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 10732 Free PE 0 Allocated PE 10732 PV UUID 5SaSBe-zk7g-3XR6-5X7a-H21x-3mW4-EJyHHN --- Physical volume --- PV Name /dev/hdc1 VG Name hxvg01 PV Size 41.93 GB / NOT usable 2.96 MB [LVM: 271.00 KB] PV# 2 PV Status available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 10733 Free PE 0 Allocated PE 10733 PV UUID gQYeny-bpfF-IoQl-8dtG-867E-OXIj-FBqmlj --- Physical volume --- PV Name /dev/hdb1 VG Name hxvg01 PV Size 76.69 GB / NOT usable 4.64 MB [LVM: 308.00 KB] PV# 3 PV Status NOT available Allocatable yes Cur LV 1 PE Size (KByte) 4096 Total PE 19631 Free PE 21 Allocated PE 19610 PV UUID 3cQksh-0OAA-ar9H-3fms-AgGQ-tOIO-eREM8v vgcfgrestore -- unlocking logical volume manager Which of the pv* vg* lv* commands are changing the physical volume (=which are dangerous for me) ? // melle -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet.
