Hey Roger,
I am seeing this weird behavior when using #linux-next + stable/for-jens-3.8 tree.
Basically I can do 'pvscan' on xvd* disk and quite often I get checksum errors:
# pvscan /dev/xvdf
PV /dev/xvdf2 VG VolGroup00 lvm2 [18.88 GiB / 0 free]
PV /dev/dm-14 VG vg_x86_64-pvhvm lvm2 [4.00 GiB / 68.00 MiB free]
PV /dev/dm-12 VG vg_i386-pvhvm lvm2 [4.00 GiB / 68.00 MiB free]
PV /dev/dm-11 VG vg_i386 lvm2 [4.00 GiB / 68.00 MiB free]
PV /dev/sda VG guests lvm2 [931.51 GiB / 220.51 GiB free]
Total: 5 [962.38 GiB] / in use: 5 [962.38 GiB] / in no VG: 0 [0 ]
# pvscan /dev/xvdf
/dev/xvdf2: Checksum error
Couldn't read volume group metadata.
/dev/xvdf2: Checksum error
Couldn't read volume group metadata.
PV /dev/dm-14 VG vg_x86_64-pvhvm lvm2 [4.00 GiB / 68.00 MiB free]
PV /dev/dm-12 VG vg_i386-pvhvm lvm2 [4.00 GiB / 68.00 MiB free]
PV /dev/dm-11 VG vg_i386 lvm2 [4.00 GiB / 68.00 MiB free]
PV /dev/sda VG guests lvm2 [931.51 GiB / 220.51 GiB free]
Total: 4 [943.50 GiB] / in use: 4 [943.50 GiB] / in no VG: 0 [0 ]
This is with a i386 dom0, 64-bit Xen 4.1.3 hypervisor, and with either
64-bit or 32-bit PV or PVHVM guest.
Have you seen something like this?
Note, the other LV disks are over iSCSI and are working fine.
