Logical Volumes (LV) are the final storage unit in the standard LVM architecture. These units are created from the volume group, which is made up of physical volumes (PV). If you have been following along in the series, you will have initialized your physical volumes and combined them into...

How to Extend/Reduce LVM’s (Logical Volume Management) in Linux How to Take ‘Snapshot of Logical Volume and Restore’ in LVM 在LVM中 录制逻辑卷快照并恢复 LVM快照是以空间换时间时间的方式制作的lvm卷副本。它只在lvm中工作,并只在源逻辑卷发生改变时占用快照卷的空间。如果源卷的变化达到1GB这么大...
这与底下要说明的 PE 以及 LVM 的格式版本有关喔~在预设的情况下, 使用 32 位的 Linux 系统时,基本上 LV 最 大仅能支持到 65534 个 PE 而已,若使用预设的 PE 为 4MB 的情况下, 最大容量则仅能达到 约 256GB 而已~不过,这个问题在 64 位的 Linux 系统上面已经不存在了!LV 几乎没有啥容 量限制了...
Managing logical volume management (LVM) in Linux requires a good understanding of how storage components – physical volumes (PVs), volume groups (VGs), and logical volumes (LVs) interact. One of the common tasks for us as system administrators is identifying which PVs store specific LVs. This...

When trying to activate logical volumes, it fails to pass the activation filter: Raw # vgchange -ay myVG Not activating myVG/lv1 since it does not pass activation filter. 0 logical volume(s) in volume group "myVG" now active I have a cluster with HA-LVM, and have added standalone st...
and /or multiple partitions combined into a single pool or Volume Group (VolGroup00) from which Logical Partitions (LogVol00..etc) can be created. This model allows linux administrators to very easily expand volumes on the fly in the event that disk space on a mount, or even the root fi...
逻辑卷Logical volume (LV):虚拟分区,由物理区域(physical extents)组成。A "virtual/logical partition" that resides in a volume group and is composed of physical extents. Think of logical volumes as normal partitions. 物理区域Physical extent (PE):硬盘可供指派给逻辑卷的最小单位(通常为4MB)。A smal...
LVM精简卷(Thinly-Provisioned Logical Volumes)的概念: As of the Red Hat Enterprise Linux 6.4 release, logical volumes can be thinly provisioned. This allows you to create logical volumes that are larger than the available extents. Using thin provisioning, you can manage a storage pool of...
