VMWARE中如何创建共享磁盘

  1. 建立共享磁盘柜

  在虚拟机软件的装置名目下,有个vmware-vdiskmanager.exe文件(老版本用plainmaker.exe),把它复制到共享磁盘柜名目下,建立共享磁盘(老版本共享磁盘文件的扩展名为.pln) F:\虚拟机\共享磁盘柜>vmware-vdiskmanager.exe -c -s 200Mb -a lsilogic -t 2 quorum.vmdk F:\虚拟机\共享磁盘柜>vmware-vdiskmanager.exe -c -s 4Gb -a lsilogic -t 2 sharedisk.vmdk 建立完毕后,名目下有四个新文件 quorum-flat.vmdk quorum.vmdk sharedisk-flat.vmdk sharedisk.vmdk 2. 设置装备摆设虚拟机 在虚拟机械界面选择“Edit virtual machine settings”à添加硬盘,选“Use a existing virtual disk”,别离添加quorum.vmdk、sharedisk.vmdk 双击新加的磁盘,在弹出的磁盘属性窗选“advance”,为新加的硬盘选择虚拟设备节点:q

uorum.vmdk选订“SCSI 0:1”,sharedisk.vmdk选定“SCSI 1:1”。 别离翻开两台虚拟机名目中的vmx文件,在最后一行添加:

  disk.locking="FALSE"

  scsi0:1.SharedBus="Virtual"

  scsi1:1.SharedBus="Virtual"

  vmware中设置共享磁盘,需求知足两个前提:

  1、硬盘的初级属性中必需 设置成1:0,假如增添第二块共享硬盘,也设成1:0,系统就会报错,所以设置成1:1(这种体例自己还没试过,不外 在oracle双机的文章中看到过如许的设置方式)

  2、需求在vmware的设置装备摆设属性文件(如rhel3.vmx)中插手两条属性 scsi[n].sharedBus = "virtual" disk.locking = "false" 系统启动的时辰会锁定磁盘,所以当启动linux1后共享磁盘被锁定了,linux2就起不来了,是以需求插手disk.locking = "false" 。 普通来说,假如是scsi1:0,则n为1,也就是scsi1.sharedBus = "virtual" ,暗示 所有的bus都共享,vmare推举这种做法。 假如说是不是所有的bus都共享的话,可以将上述scsi1.sharedBus = "virtual"改成scsi1:1.shared = "true" 。

  SCSI reservation must be enabled in a virtual machine before you can share its disks. To enable it, make sure the virtual machine is powered off. Open the configuration file (.vmx file on Windows hosts, .cfg file on Linux hosts) in a text editor and add the line scsi[n].sharedBus = "virtual" anywhere in the file, where [n] is the SCSI bus being shared.

  VMware recommends you set up the shared disks on their own SCSI bus, which is a different bus than the one the guest operating system uses. For example, if your guest operating system is on scsi0:0, you should set up disks to share on scsi1 bus.

  For example, to enable SCSI reservation for devices on the scsi1 bus, add the following line to the virtual machine's configuration file: scsi1.sharedBus = "virtual"

  This gives the whole bus the ability to be shared. However, if you would rather not share the whole bus, you can selectively enable SCSI

  reservation for a specific SCSI disk on the shared bus. This prevents the locking of this specific disk. Add the following line to the configuration file:

  scsi1:1.shared = "true"

  If SCSI reservation is enabled (that is, scsi1.sharedBus is set to "virtual"), then this setting is ignored.

  In addition to enabling SCSI reservation on the bus, you need to allow virtual machines to access the shared disk concurrently. Add the following line to the virtual machine's configuration file: disk.locking = "false"

  This setting permits multiple virtual machines to access a disk

  concurrently. Be careful though; if any virtual machine not configured for SCSI reservation tries to access this disk concurrently, then the shared disk is vulnerable to corruption or data loss.

  When SCSI reservation is enabled, a reservation lock file that contains the shared state of the reservation for the given disk is created. The name of this file consists of the filename of the SCSI disk appended with .RESLCK.

  For example, if the disk scsi1:0.filename is defined in the configuration file as

  scsi1:0.fileName = "//vmSCSI.pln"

  then the reservation lock file for this disk is given the default name "//vmSCSI.pln.RESLCK"

  However, you can provide your own lock file name. Add a definition for scsi1:0.reslckname to the configuration file. For example, if scsi1:0.reslckname = "/tmp/scsi1-0.reslock"

  is added to the configuration file, it overrides the default lock file name.

  Selecting the DiskOnce SCSI reservation is enabled for a disk — that is, the

  scsi[n].sharedBus = "virtual" and disk.locking = "false" settings are added to the configuration file for each virtual machine wanting to share this disk, you need to point to this disk for each virtual machine that wants to access it.

  在vmware中建立共享磁盘

  plainmaker曾经不消 了,此刻直接添加磁盘

  为一台机械添加一个新的虚拟磁盘,然后再为另一台机械添加一个已存在的虚拟磁盘

  然后点窜一下两台机械的设置装备摆设文件,添加如下内乱容 scsi1.sharedBus = "virtual" disk.locking = "false"

  假定两台机械的虚拟磁盘都在scsi1这个总线上。

  注重两台机械中要共享的盘的总线和总线地址应该是一样的,而且 最好不要和主机操作系统利用的盘在一个总线上。
