the following figure, 13 logical volumes (raw devices) in the volume group are not used. (if no logical volumes in the closed/syncd status are displayed, go to step 1) but how can we know how large these 13 logical volumes are? You can use the following command: # Lslv lvdata0315 Logical volume: lvdata0309 volume group: datavg09 LV identifier: 0037de1d4154c0000000105cd3b6816. 11 permission: read/write VG state: active/complete LV state: Opened/syncd

The specific code is as follows:

Bcache is the Linux kernel block layer cache. It uses SSD as the cache of the HDD hard disk to accelerate the operation. HDD disks are cheaper and have a larger space. SSD is faster but more expensive. If you can have both of them, isn't it easy? Bcache can do this. Bcache uses SSD as the cache for other Block devices. Similar to the L2Arc of ZFS, bcache also adds a write-back policy that is irrelevant to the file system. Bcache is designed to work in

do not need to exist. You can allocate storage resources when virtual machines need to store resources, flexible. Back to Top Libvirt supports backend storage types In order to provide different backend storage devices with uniform interfaces for virtual machines, libvirt divides storage management into two aspects: storage volume (volume) and storage pool ). A storage volume is a storage device that can be allocated to virtual machines. It correspon

Use Python's wx Library to write a UI interface that will output the Android device to a computer screen, as long as the ADB is installed and the Python library involved is installed. The code is as follows:ImportWx,subprocess,os,platformclassAutyframe (WX. Frame):def __init__(self): WX. Frame.__init__(Self, None,-1,'Android Auty', size= (350, 300)) Self.panel= WX.
