[linux-lvm] Recovering inconsistent vg

[linux-lvm] Recovering inconsistent vg

[Shane Wegner]

Hi all,

I'm not sure how this happened but after rebooting, I am
getting the following from vgscan.
continuum:~# vgscan
vgscan -- reading all physical volumes (this may take a
while...)
vgscan -- found inactive volume group "vg0"
vgscan -- ERROR "lv_check_consistency(): LV status" volume
group "vg0" is inconsistent
vgscan -- ERROR: unable to do a backup of volume group
"vg0"
vgscan -- ERROR "lvm_tab_vg_remove(): unlink" removing
volume group "vg0" 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

I have no idea what this means, what I can do to recover
and am hoping someone could help me out.  A pvscan yeilds:

continuum:~# pvscan
pvscan -- reading all physical volumes (this may take a
while...)
pvscan -- inactive PV "/dev/hdi1"  is associated to unknown
VG "vg0" (run vgscan)
pvscan -- inactive PV "/dev/hde1"  is associated to unknown
VG "vg0" (run vgscan)
pvscan -- inactive PV "/dev/hda1"  is associated to unknown
VG "vg0" (run vgscan)
pvscan -- total: 3 [215.74 GB] / in use: 3 [215.74 GB] / in
no VG: 0 [0]

Looks right to me.  vg0 is hda1, hde1, and hdi1.

Thanks in advance,
Shane

If this is a recent debian unstable upgrade then you should get
the latest 1:1.0.4-4 deb (uploaded this morning GMT) that fixes 
the problem.

Hi,

I've the same problem. The VG was originally created with LVM 1.0.4,
then used (and extended) with 1.1rc1. Now I've the problem after
downgrading to 1.0.4.

	# ./vgscan
	vgscan -- ERROR "lv_check_consistency(): LV status" volume group "vg00" is inconsistent
	vgscan -- ERROR: unable to do a backup of volume group "vg00"
	vgscan -- ERROR "lvm_tab_vg_remove(): unlink" removing volume group "vg00" from "/etc/lvmtab"
	vgscan -- reading all physical volumes (this may take a while...)
	vgscan -- found active volume group "vg00"
	vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
	vgscan -- WARNING: This program does not do a VGDA backup of your volume group

yeah, it's a bug in 1.1 which is fixed in the debian patched 1.0.4-4. If you
built from source here's the workaround:


diff -u -r1.4 -r1.4.2.1
--- lv_check_consistency.c      7 Feb 2002 16:19:46 -0000       1.4

@@ -42,6 +42,9 @@
 
    debug_enter ( "lv_check_consistency -- CALLED\n");
 
+   /* Don't barf on broken LVM1.1 created metadata */
+   if (lv->lv_status > 2) lv->lv_status = 1;
+
    if ( lv == NULL)                                   ret = -LVM_EPARAM;
    else if ( lv_check_name ( lv->lv_name) != 0)       ret = -LVM_ELV_LVNAME;
    else if ( vg_check_name ( lv->vg_name) != 0)       ret = -LVM_ELV_VGNAME;

Yes, that was it.  Thank you for the help.
