, as long as VG has space, then all LV under VG can enlarge capacity arbitrarily, until VG is full, VG is full, you can add PV to VG to increase the capacity of VG UNIX: Df-g used to view the LV Linux: Df-h used to view the LV Steps: 1. Create the Pv-2. Add PV to vg-4. Create lv-5 in VG. Format the LV partition-6. Mount the LV partition to a directory using Create PV [root@z1~]# pvcreate/dev/sdb1 Create pv/dev/sdb1 to make PV the first primary partition of the SCSI second hard drive [root@z1~]

in testing is to prepare the (Prepare) phase, generate the data files used for the test, and generate a data file that is at least larger than the memory. If the data in the file can be completely put into memory, the operating system caches most of the data, causing the test results to fail to reflect IO-intensive workloads. First create a DataSet with the following command:Sysbench--test=fileio--file-total-size=40g PrepareThis command creates a tes

network. Although the three-tier network configuration is complex, it can be deployed automatically through the Controller. As long as the port of the network device is connected through a cable, all network configurations are automatically deployed. For example, in a VXLAN network, as long as the network device is configured with a route to connect to the Controller, the interface address is connected, and the Controller automatically sends a VXLAN configuration when it perceives a port UP wit
