Create a striped LV with 3 stripes, a stripe size of 8KiB and a
size of 100MiB. The LV name is chosen by lvcreate.
lvcreate -i 3 -I 8 -L 100m vg00
Create a raid1 LV with two images, and a useable size of 500 MiB.
This operation requires two devices, one for each mirror image.
RAID metadata (superblock and bitmap) is also included on the two
devices.
lvcreate --type raid1 -m1 -L 500m -n mylv vg00
Create a mirror LV with two images, and a useable size of 500
MiB. This operation requires three devices: two for mirror
images and one for a disk log.
lvcreate --type mirror -m1 -L 500m -n mylv vg00
Create a mirror LV with 2 images, and a useable size of 500 MiB.
This operation requires 2 devices because the log is in memory.
lvcreate --type mirror -m1 --mirrorlog core -L 500m -n mylv vg00
Create a copy-on-write snapshot of an LV:
lvcreate --snapshot --size 100m --name mysnap vg00/mylv
Create a copy-on-write snapshot with a size sufficient for
overwriting 20% of the size of the original LV.
lvcreate -s -l 20%ORIGIN -n mysnap vg00/mylv
Create a sparse LV with 1TiB of virtual space, and actual space
just under 100MiB.
lvcreate --snapshot --virtualsize 1t --size 100m --name mylv vg00
Create a linear LV with a usable size of 64MiB on specific
physical extents.
lvcreate -L 64m -n mylv vg00 /dev/sda:0-7 /dev/sdb:0-7
Create a RAID5 LV with a usable size of 5GiB, 3 stripes, a stripe
size of 64KiB, using a total of 4 devices (including one for
parity).
lvcreate --type raid5 -L 5G -i 3 -I 64 -n mylv vg00
Create a RAID5 LV using all of the free space in the VG and
spanning all the PVs in the VG (note that the command will fail
if there are more than 8 PVs in the VG, in which case -i 7 must
be used to get to the current maximum of 8 devices including
parity for RaidLVs).
lvcreate --config allocation/raid_stripe_all_devices=1
--type raid5 -l 100%FREE -n mylv vg00
Create RAID10 LV with a usable size of 5GiB, using 2 stripes,
each on a two-image mirror. (Note that the -i and -m arguments
behave differently: -i specifies the total number of stripes, but
-m specifies the number of images in addition to the first
image).
lvcreate --type raid10 -L 5G -i 2 -m 1 -n mylv vg00
Create a 1TiB thin LV mythin, with 256GiB thinpool tpool0 in
vg00.
lvcreate -T -V 1T --size 256G --name mythin vg00/tpool0
Create a 1TiB thin LV, first creating a new thin pool for it,
where the thin pool has 100MiB of space, uses 2 stripes, has a
64KiB stripe size, and 256KiB chunk size.
lvcreate --type thin --name mylv --thinpool mypool
-V 1t -L 100m -i 2 -I 64 -c 256 vg00
Create a thin snapshot of a thin LV (the size option must not be
used, otherwise a copy-on-write snapshot would be created).
lvcreate --snapshot --name mysnap vg00/thinvol
Create a thin snapshot of the read-only inactive LV named
"origin" which becomes an external origin for the thin snapshot
LV.
lvcreate --snapshot --name mysnap --thinpool mypool vg00/origin
Create a cache pool from a fast physical device. The cache pool
can then be used to cache an LV.
lvcreate --type cache-pool -L 1G -n my_cpool vg00 /dev/fast1
Create a cache LV, first creating a new origin LV on a slow
physical device, then combining the new origin LV with an
existing cache pool.
lvcreate --type cache --cachepool my_cpool
-L 100G -n mylv vg00 /dev/slow1
Create a VDO LV vdo0 with VDOPoolLV size of 10GiB and name
vpool1.
lvcreate --vdo --size 10G --name vdo0 vg00/vpool1
