£ Country Indian Whisky. Distillery/Brand Amrut. Style Single Malt Whisky. Natural Cask Strength? Yes. Amrut Cask Strength. A natural cask strength release from the Amrut distillery, awarded 93.5 points by Jim Murray. Tasting Note by The Chaps at Master of Malt. Nose Biscuity, fruity, fig-rolls, herbal, Werther's Originals, almost pepperminty.Amrut Indian Cask Strength Single Malt Whisky – The extra proof hasn’t made this whisky punchier on the nose, but it does restrain the fruit, leaving drier notes of light-roast coffee, chocolate shavings, and pastry crust behind.
Cloning Logical Volume using LVM UPDATE: more LVM2 recipes here. And here is how to Shrinking root LV on-line. Sometime it is necessary to clone full LV (Logical Volume). Here we will try to do this using LVM2 commands. First let's create a test LV:
As of the LVM in Debian stretch (9.0), namely 2.02.168-2, it's possible to do a copy of a logical volume across volume groups using a combination of vgmerge, lvconvert, and vgsplit. Since a move is a combination of a copy and a delete, this will also work for a move.As of the LVM in Debian stretch (9.0), namely 2.02.168-2, it's possible to do a copy of a logical volume across volume groups using a combination of vgmerge, lvconvert, and vgsplit. Since a move is a combination of a copy and a delete, this will also work for a move.Clone the harddisk, with "dd". For every physical volume, generate new UUIDs for the clone disk, with "pvchange -u /dev/hdb*". Change the VG UUID with "vgchange -u LVM". This will change the UUID of one of the VG, could be the original or the clone. .

There is a slight catch. I want to swap some of the drives. I have: VG1: LV: PV (OldDrive1) + PV (OldDrive2) sda (OldDrive1) -vg1-luks_encrypted_lv. sdb (OldDrive2) -vg1-luks_encrypted_lv. I think one possible solution is to clone the LVM partitions to regular partitions in another disk using dd, and then clone the new disk to the other machines using partclone. But I do not know if something like this will work:
I would like to clone a smaller LVM-formatted disk onto a larger one using dd, and boot that disk in the same machine. Do I need to make any special considerations for LVM? Thanks!I'd like to know how it's possible using the lvm cli tool to clone an existing lvm thin volume, creating another thin-volume with the same contents (but possibly a larger size) as the original one. So something like LXC does when you execute lxc-clone.
