I tried a different approach to this.
I made /dev/md2 visible in the guest as xvdb1:
disk = [ 'phy:vg_host/lv_slim,xvda,w',
'phy:md2,xvdb1,w', ]
Now, the VG is being detected when the guest boots up:
Scanning logical volumes
Reading all physical volumes. This may take a while...
Found volume group "vg_media" using metadata type lvm2
Found volume group "vg_slim" using metadata type lvm2
And, from a root shell, both the VG and the LV are visible:
# vgs
VG #PV #LV #SN Attr VSize VFree
vg_media 1 1 0 wz--n- 2.73T 0
vg_slim 1 6 0 wz--n- 9.88G 32.00M
# lvdisplay vg_media/lv_media
--- Logical volume ---
LV Name /dev/vg_media/lv_media
VG Name vg_media
LV UUID KK4J0k-OgoI-441I-lYa2-OF1k-C4FW-g4qi7o
LV Write Access read/write
LV Status available
# open 0
LV Size 2.73 TB
Current LE 715406
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:6
/dev/mapper/vg_media-lv_media is present but there's no device file in
/dev, i.e. /dev/vg_media/lv_media does not exists.
I did notice an error if I try to activate all VGs:
# vgchange -ay
device-mapper: reload ioctl failed: Invalid argument
1 logical volume(s) in volume group "vg_media" now active
6 logical volume(s) in volume group "vg_slim" now active
So, any idea what's going on here?
How can I make this filesystem available to my guest?
Thanks,
R.
