Add a new 5G hard drive to VMwareShow current partition# fdisk-lUsually when you add a new hard disk to a virtual machine, you may see that the new drive is not loaded automatically. This is because the SCSI bus connected to the hard drive needs to be re-scanned to make the new hard drive visible.Here is a simple command to rescan the SCSI bus and SCSI devices.Determine the host bus number# LS /sys/class/scsi_host/ Host0 host11 host14 host1

Create a 5G partition, the file system is ext2, the volume is labeled data, the block size is 1024, the reserved administrative space is 8% of the disk partition, mount to the/backup directory, require the use of the volume label to mount, and on the mount when the ACL function on the file system is started;after the virtual machine has created a hard disk, use the FDISK-L command to see if the system recognizesStart preparing to partition the hard di

see@ Card farmer Solo : 5G technology is successful, according to the Daily Mail of the UK, scientists at the University of Surrey in the UK have recently developed the latest and fastest 5G network technology. It can transmit about 125GB of data per second, 65,000 times times faster than current 4G technology. At this speed, the current 30 movies can be downloaded per second. (CCTV net)With the 4g,
