Linux如何在VMware下扩展磁盘
本文就来介绍一下Linux如何在VMware下扩展磁盘。 1:VMware虚拟磁盘扩容 如下所示,VMware虚拟磁盘扩容后,使用fdisk -l看不到任何变化 [root@localhost ~]# fdisk -l Disk /dev/sda: 171.7 GB, 171798691840 bytes 255 heads, 63 sectors/track, 20886 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 15665 125724690 8e Linux LVM /dev/sda3 15666 15795 1044225 83 Linux /dev/sda4 15796 20886 40893457+ 83 Linux Disk /dev/dm-0: 126.6 GB, 126600871936 bytes 255 heads, 63 sectors/track, 15391 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-0 doesn‘t contain a valid partition table Disk /dev/dm-1: 2113 MB, 2113929216 bytes 255 heads, 63 sectors/track, 257 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-1 doesn’t contain a valid partition table 方法1:echo 1 》 /sys/class/scsi_device/device/rescan [root@localhost ~]# cd /sys/class/scsi_disk/ [root@localhost scsi_disk]# ls 0:0:0:0 [root@localhost scsi_disk]# cd 0\:0\:0\:0/ [root@localhost 0:0:0:0]# echo ‘1’ 》 device/rescan [root@localhost 0:0:0:0]# fdisk -l Disk /dev/sda: 173.9 GB, 173946175488 bytes 255 heads, 63 sectors/track, 21147 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 15665 125724690 8e Linux LVM /dev/sda3 15666 15795 1044225 83 Linux /dev/sda4 15796 20886 40893457+ 83 Linux Disk /dev/dm-0: 126.6 GB, 126600871936 bytes 255 heads, 63 sectors/track, 15391 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-0 doesn‘t contain a valid partition table Disk /dev/dm-1: 2113 MB, 2113929216 bytes 255 heads, 63 sectors/track, 257 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-1 doesn’t contain a valid partition table 方法2:重新扫描特定的 SCSI Device echo 1 》 /sys/block/$DEVICE/device/rescan 用sda, sdb, sdc等替换$DEVICE [root@localhost ~]# echo 1 》 /sys/block/sda/device/rescan 2:VMware新增虚拟磁盘 首先找到您的主机总线编号 [root@localhost ~]# grep mpt /sys/class/scsi_host/host?/proc_name /sys/class/scsi_host/host0/proc_name:mptspi 使用下面命令扫描SCSI总线 [root@localhost ~]# echo “- - -” 》 /sys/class/scsi_host/host0/scan 好啦,以上就是华军小编带给大家的全部内容了,是不是很简单呢?你学会了么?想了解更多的相关内容,请随时关注华军资讯动态吧,欢迎到华军来下载哦!
