What is LVM extent size?
The physical volumes are divided into 4MB units, since that is the extent size. In this example, PV1 is 200 extents in size (800MB) and PV2 is 100 extents in size (400MB). You can create a linear volume any size between 1 and 300 extents (4MB to 1200MB).
How increase FS size in Linux?
To extend the file system on each volume, use the correct command for your file system, as follows:
- [XFS volumes] To extend the file system on each volume, use the xfs_growfs command.
- [ext4 volumes] To extend the file system on each volume, use the resize2fs command.
What is extent size in Linux?
The physical extent (PE) size is the basic unit out of which logical volumes are created. It defines the minimum size of a volume and the possible increments (having a 4MB PE size would mean the minimum volume size is 4MB and you can grow it in 4MB increments).
What is the default physical extent size?
-e MaxPhysicalExtents Sets the maximum number of physical extents that can be allocated from any of the physical volumes in the volume group. The default is 1016.
How can I increase the size of my LVM partition?
Alternatively if you have multiple LVM partitions, you could shrink a different logical volume first to create space within the volume group. Now that we have confirmed there is space free within the volume group, confirm the name of the logical volume you want to increase as well as how much space you plan on adding.
How to extend the volume group in LVM?
for extending what we have to do is, we need to add one physical volume (PV) and then we have to extend the volume group (VG) by extending the VG then we will get enough space to increase the logical volume size, so first will add one physical volume For adding the PV we need to create one LVM partition with “ fdisk” command
How much space is allocated to the LVM?
So in this case, the Physical disk is 32 GB, but only 8 GB are currently allocated to the LVM and no other partitions are using the rest of the space for anything else. So we can extend it!
How many physical extend ( PE ) are there in LVM?
Currently there are 4226 Physical Extend (PE) available. Now we are going to expand the / partition LogVol01. After expanding we can list out the size as above for confirmation.
