2024年11月Linux如何在VMware下扩展磁盘

发布时间:

  ⑴在Linux系统中,如果要扩展磁盘容量,可以新建虚拟磁盘空间。新建虚拟磁盘重启后就能生效了,当然如果你有什么重要的在执行的任务,而不想重启,也是有办法的。本文就来介绍一下Linux如何在VMware下扩展磁盘。

  ⑵:VMware虚拟磁盘扩容

  ⑶如下所示,VMware虚拟磁盘扩容后,使用fdisk -l看不到任何变化

  ⑷[rootlocalhost ~]# fdisk -l

  ⑸Disk /dev/sda: . GB, bytes

  ⑹ heads, sectors/track, cylinders

  ⑺Units = cylinders of * = bytes

  ⑻Device Boot Start End Blocks Id System

  ⑼/dev/sda * Linux

  ⑽/dev/sda e Linux LVM

  ⑾/dev/sda Linux

  ⑿/dev/sda + Linux

  ⒀Disk /dev/dm-: . GB, bytes

  ⒁ heads, sectors/track, cylinders

  ⒂Units = cylinders of * = bytes

  ⒃Disk /dev/dm- doesn‘t contain a valid partition table

  ⒄Disk /dev/dm-: MB, bytes

  ⒅ heads, sectors/track, cylinders

  ⒆Units = cylinders of * = bytes

  ⒇Disk /dev/dm- doesn’t contain a valid partition table

  ⒈方法:echo 》 /sys/class/scsi_device/device/rescan

  ⒉[rootlocalhost ~]# cd /sys/class/scsi_disk/

  ⒊[rootlocalhost scsi_disk]# ls

  ⒋[rootlocalhost scsi_disk]# cd :::/

  ⒌[rootlocalhost :::]# echo ‘’ 》 device/rescan

  ⒍[rootlocalhost :::]# fdisk -l

  ⒎Disk /dev/sda: . GB, bytes

  ⒏ heads, sectors/track, cylinders

  ⒐Units = cylinders of * = bytes

  ⒑Device Boot Start End Blocks Id System

  ⒒/dev/sda * Linux

  ⒓/dev/sda e Linux LVM

  ⒔/dev/sda Linux

  ⒕/dev/sda + Linux

  ⒖Disk /dev/dm-: . GB, bytes

  ⒗ heads, sectors/track, cylinders

  ⒘Units = cylinders of * = bytes

  ⒙Disk /dev/dm- doesn‘t contain a valid partition table

  ⒚Disk /dev/dm-: MB, bytes

  ⒛ heads, sectors/track, cylinders

  ①Units = cylinders of * = bytes

  ②Disk /dev/dm- doesn’t contain a valid partition table

  ③方法:重新扫描特定的 SCSI Device

  ④echo 》 /sys/block/$DEVICE/device/rescan 用sda, sdb, sdc等替换$DEVICE

  ⑤[rootlocalhost ~]# echo 》 /sys/block/sda/device/rescan

  ⑥:VMware新增虚拟磁盘

  ⑦首先找到您的主机总线编号

  ⑧[rootlocalhost ~]# grep mpt /sys/class/scsi_host/host?/proc_name

  ⑨/sys/class/scsi_host/host/proc_name:mptspi

  ⑩使用下面命令扫描SCSI总线

  Ⅰ[rootlocalhost ~]# echo “- - -” 》 /sys/class/scsi_host/host/scan

  Ⅱ以上就是Linux如何在VMware下扩展磁盘的介绍了,使用上面的两个步骤扩展磁盘,不需要重启系统,虚拟磁盘就能立即被系统识别。
