Hello all, I'm new to this list (since this is the first major problem i've had with LVM) so please bare with me and let me know what i need to submit for help. Here's the situation: I wanted to upgrade from Slackware 8.1 to Slackware 9.0. On the system I had a volume group (vg00) of 4 disks (hde1 through hdh1). The LVM was running fine. I first attempted to do the upgrade to slack 9 without a full reinstall (using swaret) but didn't like some of the results with other parts of the system. LVM is still fine at the point. So, I prepare to do a full upgrade. I figured the best way to do this would be to export the LVM on the running system, do the upgrade to slack 9 with a fresh clean install, then import the LVM back in. These were the commands I planned to use: On old system: vgchange -an vg00 vgexport vg00 On new system: vgimport vg00 /dev/hde1 vgchange -ay vg00 So, as a test, I figured I would run this set of commands on the system without the upgrade. Here's where things went wrong. I did the vgchange and the vgexport... No problem, go to do the vgimport and I get vgimport -- ERROR "vg_read_with_pv_and_lv(): current PV" reading data of volume group "vg00" eek... okay, so i try a vgscan with these results: vgscan -- reading all physical volumes (this may take a while...) vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of volume group "vg00PV_EXP" from physical volume(s) vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group and a pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- inactive PV "/dev/hdg1" is in EXPORTED VG "vg00" [38.16 GB / 0 free] pvscan -- inactive PV "/dev/hdh1" is in EXPORTED VG "vg00" [57.26 GB / 0 free] pvscan -- inactive PV "/dev/hde1" is in EXPORTED VG "vg00" [28.61 GB / 0 free] pvscan -- total: 3 [124.05 GB] / in use: 3 [124.05 GB] / in no VG: 0 [0] So i see that /dev/hdf1 is missing... :( so pvdisplay /dev/hdf1 pvdisplay -- ERROR "pv_read(): LVM structure version" no VALID physical volume "/dev/hdf1" so i try a vgcfgrestore (yes, i saved a copy) -n vg00 /dev/hdf1 vgcfgrestore -- this is a backup of volume group "vg00" vgcfgrestore -- ERROR "pv_read(): LVM structure version" reading physical volume "/dev/hdf1" So I think to myself "maybe it was the half upgrade to 9"... So I did a complete reinstall of 8.1 - same results, so I did a clean install of 9 - same results... It seems like no matter what I do, I get the LVM structure version error. So my real question is, is there any way to fix this? I tried playing around with a script pvversion that was supposed to change the structure version, but it didn't seem to do anything. If I can't fix this drive, i'm willing to bite the loss of the data on that drive, but I can't seem to find a way to bring back the volume group without that drive intact. If I throw another drive in it's place and run a vgcfgrestore on it, it works - but then I have that one drive there, and 3 exported drives. Can i somehow import those 3 with the 1 replacement? Or, am I completely out of luck and have lost the whole group? Any help is greatly appreciated... I can supply any other command results that anyone thinks would be helpful. If it comes to it i could possibly give someone ssh access to the box (nothing else on it at the moment anyway). Feel free to email me directly, otherwise I will be monitoring the thread.
