I've created a pv, then a vg, and then a logical volume size 2GB with sudo lvcreate -L +2GB -n lv-test vg-test. Then I formatted this volume with: sudo mkfs.ext4 /dev/vg-test/lv .
lvcreate creates a new LV in a VG. For standard LVs, this re‐ quires allocating logical extents from the VG's free physical ex‐ tents. If there is not enough free space, the VG can be .The lvcreate command is a powerful tool for creating logical volumes in an existing volume group. It allows us to specify the size, name, and utilization of space for logical volumes. By . You can use the -l argument of the lvcreate command to specify the size of the logical volume in extents. You can also use this argument to specify the percentage of of the .

Commands and Their Functions: lvcreate – A command used to create logical volumes in a volume group managed by the Logical Volume Manager (LVM).-L – Specifies the size of the logical volume to be created.-n – Defines the name of .For example, use the lvcreate --type raid10 -i 2-m 1-L 10G--maxrecoveryrate 128-n my_lv my_vg command to create a 2-way RAID10 array my_lv, which is in the volume group my_vg with 3 stripes that is 10G in size with a maximum .If the original logical volume contains a file system, you can mount the snapshot logical volume on an arbitrary directory in order to access the con‐ tents of the filesystem to run a backup while the original filesystem continues to get updated: lvcreate --size 100m --snapshot --name snap /dev/vg00/lvol1 Creates a snapshot logical volume .
sudo lvcreate --snapshot --name lv_snapshot --size 5g foo/bar This will create a snapshot named lv_snapshot of the original logical volume bar and allocate 5 GB of space for it. Since the snapshot volume only stores the areas of the disk that have changed since it was created, it can be much smaller than the original volume. .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 1 TiB of virtual space, and actual space just under 100 MiB.Pages related to lvcreate. lvchange (8) - Change the attributes of logical volume(s) lvconvert (8) - Change logical volume layout lvdisplay (8) - Display information about a logical volume lvextend (8) - Add space to a logical volume lvm-config (8) - Display and manipulate configuration information lvm-dumpconfig (8) - Display and manipulate configuration information
lvcreate is a Linux command used to create a logical volume (LV) in a Linux Logical Volume Manager (LVM) setup. A logical volume is a virtual block device that provides a layer of abstraction between the physical storage and the file system. This allows for more flexible and dynamic management of storage, such as resizing and moving of volumes without affecting . $ sudo vgdisplay --- Volume group --- VG Name vol_grp1 System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 1 VG Access read/write VG Status resizable MAX LV 0 Cur LV 0 Open LV 0 Max PV 0 Cur PV 2 Act PV 2 VG Size 3.72 GB PE Size 4.00 MB Total PE 952 Alloc PE / Size 0 / 0 Free PE / Size 952 / 3.72 GB VG UUID Kk1ufB-rT15-bSWe-5270 .$ sudo fdisk -l Disk /dev/sdb: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders, total 83886080 sectors Units # sectors of 1 * 512 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sda: 85.9 .Maximum size of a physical volume. 2 TB. 16 TB. 16 TB.

If the original logical volume contains a file system, you can mount the snapshot logical volume on an arbitrary directory in order to access the contents of the filesystem to run a backup while the original filesystem continues to get updated: lvcreate--size 100m--snapshot--name snap /dev/vg00/lvol1 Creates a sparse device named /dev/vg1 . The -n option is used to indicate a name for the LV, whereas -L sets a fixed size and -l (lowercase L) is used to indicate a percentage of the remaining space in the container VG. # lvcreate -n vol_projects -L 10G vg00 # .# btrfs filesystem resize max /mnt/my-mountpoint. To reduce the size of logical volume mediavol in MyVolGroup by 500 MiB, . # lvcreate --size 100M --snapshot --name snap01vol /dev/MyVolGroup/lvol With that volume, you may modify less than 100 MiB of data, before the snapshot volume fills up.

Gives the size to allocate for the new logical volume. A size suffix of B for bytes, S for sectors as 512 bytes, K for kilobytes, M for megabytes, G for gigabytes, T for terabytes, P for petabytes or E for exabytes is optional. . lvcreate -y --type thin-pool --zero n -c 512K --poolmetadatasize 1041s -L 500M -n docker-pool docker_vg This .PE Size is the physical extent size, which is the smallest size a logical volume can be allocated. It is also the multiplying factor when calculating the size of any value reported in PE units, such as Free PE; for example: 26 PEs x 4 MiB (the PE Size) equals 104 MiB of free space. A logical volume size is rounded to a factor of PE units.lvcreate creates a new logical volume in a volume group ( see vgcreate(8), vgchange(8) ) by allocating logical extents from the free physi- cal extent pool of that volume group. . lvcreate --size 100m --snapshot--name snap /dev/vg00/lvol1 Creates a sparse device named /dev/vg1/sparse of size 1TB with space for just under 100MB of actual data .Create a copy-on-write snapshot of an LV: lvcreate --snapshot --size 100m --name mysnap vg00/mylv.
