Hi all,
I have create a Thin lvm and installed a guest os on it,
Now when i cloned that lvm using virt-clone
# virt-clone --prompt --force --original lvm_thin1 --name lvm_thin2 --file
/dev/volgrp/lvm_thin2
The cloned Disk lvm_thin2 size is fully expanded , But I want a thin Lvm cloned
image
Well according to my best of knowledge , It could be because the when lvm is
getting cloned, The zero are read from the original image
#lvs
LV
VG
Attr
LSize
Pool Origin
Data%
lvm_thin1
Volgrp

pool

lvm_thin2
volgrp
Vwi-a-tz
8.00g
pool
100.00
pool
volgrp
twi-a-tz
100.00g
8.97
As you can see above the original LVM utilize only 12.18% disk space from the
pool, but the cloned lvm_thin2 is fully expanded.
Is there is any way how can I clone a THIN LVM without fully expanding it ? Or
Is there any way to shrink the cloned LVM to that size without loss of data.
Regards
Pankaj Rawat
