[linux-lvm] LV only detected when using "lvscan -D" on amd64 kernel



Hi,

i have an amd64-based machine, upgraded from a normal one. I'm using debian, right now still the 32bit version (except for compiling the kernel).

I'm using
Linux opt 2.4.22-bk38 #4 SMP Wed Oct 22 06:44:13 UTC 2003 x86_64 GNU/Linux

using
# dmesg  | grep "LVM"
LVM version 1.0.7(28/03/2003)

The LVM consists of 4 disks, two 40GB, one 20GB and one 120GB, gives a total of roughly 220GB. All disks seem to work properly,
pvscan gives
# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE PV "/dev/hdg" of VG "fast" [115.03 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hdf" of VG "fast" [19.16 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hdc" of VG "fast" [38.16 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hdd" of VG "fast" [38.16 GB / 0 free]
pvscan -- total: 4 [210.54 GB] / in use: 4 [210.54 GB] / in no VG: 0 [0]


vgscan gives
# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "fast"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume group


so everything looks fine. The logical volume worked fine with the old kernel (2.4.20 or something like this, for ia32.).

but
# lvscan
lvscan -- no logical volumes found

and
# vgdisplay
--- Volume group ---
VG Name               fast
VG Access             read/write
VG Status             available/resizable
VG #                  0
MAX LV                256
Cur LV                0
Open LV               0
MAX LV Size           255.99 GB
Max PV                256
Cur PV                4
Act PV                4
VG Size               210.52 GB
PE Size               4 MB
Total PE              53893
Alloc PE / Size       0 / 0
Free  PE / Size       53893 / 210.52 GB
VG UUID               NiBxzC-W5zF-Mb37-5ajN-ljE9-5k53-Fzc26O

So the logical volume seems to be gone :/

HOWEVER,

# lvscan -D
lvscan -- reading all physical volumes (this may take a while...)
lvscan -- inactive          "/dev/fast/lvol1" [210.52 GB]
lvscan -- 1 logical volumes with 210.52 GB total in 1 volume group
lvscan -- 1 inactive logical volumes

and

# vgdisplay -D
--- Volume group ---
VG Name               fast
VG Access             read/write
VG Status             NOT available/resizable
VG #                  0
MAX LV                256
Cur LV                1
Open LV               0
MAX LV Size           255.99 GB
Max PV                256
Cur PV                4
Act PV                4
VG Size               210.52 GB
PE Size               4 MB
Total PE              53893
Alloc PE / Size       53893 / 210.52 GB
Free  PE / Size       0 / 0
VG UUID               NiBxzC-W5zF-Mb37-5ajN-ljE9-5k53-Fzc26O

so i think there must be still some hope. Looks like the kernel LVM stuff is somehow broken. Can this be a 64bit issue? Is there anything i could test/upgrade/whatever? Do you need more outputs?
Or did i simply forget to do anything?



thanks, Felix
