Hi,
I'm trying to map a RBD snapshot, which contains an LVM PV.
I can do the «map» :
rbd map hdd3copies/jason@20130415-065314 --id alg
Then pvscan works :
pvscan | grep rbd
PV /dev/rbd58 VG vg-jason lvm2 [19,94 GiB / 1,44 GiB free]
But enabling LV doesn't work :
# vgchange -ay vg-jason
device-mapper: reload ioctl failed: Argument invalide
Internal error: Maps lock 13746176 < unlock 13889536
device-mapper: reload ioctl failed: Argument invalide
device-mapper: reload ioctl failed: Argument invalide
device-mapper: reload ioctl failed: Argument invalide
device-mapper: reload ioctl failed: Argument invalide
device-mapper: reload ioctl failed: Argument invalide
device-mapper: reload ioctl failed: Argument invalide
7 logical volume(s) in volume group "vg-jason" now active
# blockdev --getsize64 /dev/mapper/vg--jason-*

Is it a problem from LVM, or I should not use snapshots like that ?
