Resizing alogical volume in Linuxis not very difficult and can be achieved through very straightforward approach. Here are the usual steps: Create a new partition on hard disk. Add the partition you just created as a physical volume.
Physical Volume name, a device path under /dev. For commands managing physical extents, a PV positional arg generally accepts a suffix indicating a range (or multiple ranges) of physical extents (PEs). When the first PE is omitted, it defaults to the start of the device, and when the las...
在去年的一篇文章里,我们实现了 vhost-user-blk 关于 resize volume 的支持。同时,也简单介绍了 virtio-scsi 如何感知到 resize 事件的。本文继续那篇文章遗留的问题,给 SPDK 加上 vhost-user-scsi 的 resize 支持。 跟vhost-user-blk 不同,因为 SCSI 有丰富的命令支持,获取大小可以通过 SCSI 命令来实现。 在...
Here we show you how to expand an LVM volume or partition in Linux by first resizing logical volume followed by resizing the file system to take advantage of the additional space. See here if you’re instead trying to do the opposite andshrink an LVM volume. Note:In this example we are ...
Physical volume "/dev/xvdc" successfully created. When you attach the new storage/dev/xvdc, you need to use thepvcreatecommand in order for the disk to be initialized and be seen by the Logical Volume Manager (LVM). [ You might also like:Creating and managing partitions in Linux with pa...
A filesystem on a logical volume can be extended using the LVM tool whenever logical volume shorts for space. The extended logical volume has more space and capacity than previous logical volume. This article will discuss how LVM command-line interface a
