++=============== ++ ++Support for creating LVM VDO devices has been added in Blivet 3.4. ++ ++These devices are similar to LVM thinly provisioned volumes, but there are some special steps ++and limitations when creating these devices which this document describes. ++ ++LVM VDO in Blivet ++----------------- ++ ++LVM VDO devices are represented by two ``LVMLogicalVolumeDevice`` devices: ++ ++- VDO Pool logical volume with type 'lvmvdopool' ++- VDO logical volume with type 'lvmvdolv' which is the child of the VDO Pool device ++ ++Existing LVM VDO setup in Blivet: ++ ++ existing 20 GiB disk vdb (265) with existing msdos disklabel ++ existing 20 GiB partition vdb1 (275) with existing lvmpv ++ existing 20 GiB lvmvg data (284) ++ existing 10 GiB lvmvdopool data-vdopool (288) ++ existing 50 GiB lvmvdolv data-vdolv (295) ++ ++When creating LVM VDO setup using Blivet these two devices must be created together as these ++are created by a single LVM command. ++ ++It currently isn't possible to create additional VDO logical volumes in the pool. It is however ++possible to create multiple VDO pools in a single volume group. ++ ++Deduplication and compression are properties of the VDO pool. Size specified for the VDO pool ++volume will be used as the "physical" size for the pool and size specified for the VDO logical volume ++will be used as the "virtual" size for the VDO volume. ++ ++When creating format, it must be created on the VDO logical volume. For filesystems with discard ++support, no discard option will be automatically added when calling the ``mkfs`` command ++(e.g. ``-K`` for ``mkfs.xfs``). ++ ++Example for creating a *80 GiB* VDO pool with *400 GiB* VDO logical volume with an *ext4* format with ++both deduplication and compression enabled: ++ ++ pool = b.new_lv(size=Size("80GiB"), parents=[vg], name="vdopool", vdo_pool=True, ++ deduplication=True, compression=True) ++ b.create_device(pool) ++ ++ lv = b.new_lv(size=Size("400GiB"), parents=[pool], name="vdolv", vdo_lv=True, ++ fmt_type="ext4") ++ b.create_device(lv) ++ ++When removing existing LVM VDO devices, both devices must be removed from the devicetree and the VDO ++logical volume must be removed first (``recursive_remove`` can be used to automate these two steps). ++ ++Managing of existing LVM VDO devices is currently not supported. ++ ++ ++LVM VDO in Devicefactory ++------------------------ ++ ++For the top-down specified creation using device factories a new ``LVMVDOFactory`` factory has been ++added. Factory device in this case is the VDO logical volume and is again automatically created ++together with the VDO pool. ++ ++Example of creating a new LVM VDO setup using the ``devicefactory`` module: ++ ++ factory = blivet.devicefactory.LVMVDOFactory(b, size=Size("5 GiB"), virtual_size=Size("50 GiB"), ++ disks=disks, fstype="xfs", ++ container_name="data", ++ pool_name="myvdopool", ++ compression=True, deduplication=True) ++ factory.configure() ++ factory.device ++ ++ LVMLogicalVolumeDevice instance (0x7f14d17422b0) -- ++ name = data-00 status = False id = 528 ++ children = [] ++ parents = ['non-existent 5 GiB lvmvdopool data-myvdopool (519)'] ++ ... ++ ++``size`` in this case sets the pool (physical) size, the VDO logical volume size can be specified ++with ``virtual_size`` (if not specified it will be same as the pool size). Name for the VDO volume ++can be specified using the ``name`` keyword argument. ``pool_name`` argument is optional and ++a unique name will be generated if omitted. Both ``compression`` and ``deduplication`` default to ++``True`` (enabled) if not specified. ++ ++This factory can create only a single VDO logical volume in a single VDO pool but additional VDO pools ++can be added by repeating the steps to create the first one. + +From c6c776cf137b5c6ae454487df469e9a6dba8a5d1 Mon Sep 17 00:00:00 2001 +From: Vojtech Trefny +Date: Wed, 9 Dec 2020 14:06:27 +0100 +Subject: [PATCH 14/17] Set minimum size for LVM VDO pool devices + +--- + blivet/devicefactory.py | 3 +++ + blivet/devices/lvm.py | 26 ++++++++++++++++++++++++++ + tests/devicefactory_test.py | 29 ++++++++++++++++++++--------- + tests/devices_test/lvm_test.py | 6 ++++++ + 4 files changed, 55 insertions(+), 9 deletions(-) + +diff --git a/blivet/devicefactory.py b/blivet/devicefactory.py +index 085f2fd6..5e47eb9a 100644 +--- a/blivet/devicefactory.py ++++ b/blivet/devicefactory.py +@@ -277,6 +277,7 @@ class DeviceFactory(object): + "container_size": SIZE_POLICY_AUTO, + "container_raid_level": None, + "container_encrypted": None} ++ _device_min_size = Size(0) # no limit by default, limited only by filesystem size + + def __init__(self, storage, **kwargs): + """ +@@ -1760,6 +1761,8 @@ class LVMVDOFactory(LVMFactory): + :type deduplication: bool + """ + ++ _device_min_size = LVMVDOPoolMixin._min_size ++ + def __init__(self, storage, **kwargs): + self.pool_name = kwargs.pop("pool_name", None) + self.virtual_size = kwargs.pop("virtual_size", None) +diff --git a/blivet/devices/lvm.py b/blivet/devices/lvm.py +index 0802e2de..785fa2d2 100644 +--- a/blivet/devices/lvm.py ++++ b/blivet/devices/lvm.py +@@ -1792,6 +1792,7 @@ def populate_ksdata(self, data): + class LVMVDOPoolMixin(object): + + _external_dependencies = [availability.BLOCKDEV_LVM_PLUGIN, availability.BLOCKDEV_LVM_PLUGIN_VDO] ++ _min_size = Size("5 GiB") # 2.5 GiB for index and one 2 GiB slab rounded up to 5 GiB + + def __init__(self, compression=True, deduplication=True, index_memory=0, write_policy=None): + self.compression = compression +@@ -1800,6 +1801,9 @@ def __init__(self, compression=True, deduplication=True, index_memory=0, write_p + self.write_policy = write_policy + self._lvs = [] + ++ if not self.exists and self.size < self.min_size: ++ raise ValueError("Requested size %s is smaller than minimum %s" % (self.size, self.min_size)) ++ + @property + def is_vdo_pool(self): + return self.seg_type == "vdo-pool" +@@ -1856,6 +1860,23 @@ def direct(self): + """ Is this device directly accessible?
