Logical Volume Manager is a part of Linux OS kernel, which manages hard disk and other mass storage devices. It is a way of allocating drive space into various Logical Volumes (L V ) , which can easily be extended or resized instead of doing this with hard disk partitions.
You can easily extend a LV, using lvextend utility. It also supports extension of the snapshot LV. Absolute back up is to be created first before proceeding towards extending a Linux LV. In case the logical volume extending process gets interrupted, you may lose access to logical volumes and encounter data loss. At this point, you have to opt for Linux data recovery software to get your valuable data back.
The lvextend command-line utility, offers you the following options to perform a series of operations on your logical volume-
1) -l, –extents [+]LogicalExtentsNumber[%{VG|LV|FREE}]: It sets or extends the size of LV in units of the logical extents. With + sign, value is contributed to actual size of volume and without this, value is accepted as absolute one.
2) -L, –size [+]LogicalVolumeSize[kKmMgGtTpPeE]: Sets or extends size of LV in the units of MB.
3) -i, –stripes Stripes: Provides number of the stripes for extension. This option is not usable with the LV, which use original metadata LVM format that must use single value throughout.
4) -I, –stripesize StripeSize: Provides number of the kb for granularity of stripes. It does not work on LV, which use original meta data LVM format that must use single value throughout.
All the above options are very useful in modifying a logical volume. However, serious problems occur if the process is interrupted due to any reasons, such as system crash, improper system shutdown,power outages and user error. In such cases, the volume can not be accessed and you encounter severe data loss, which require Linux recovery Software to be fixed.
Data Recovery Linux is best possible using advanced and efficient Linux recovery software. They recover lost data safely and easily in all data loss situations.
