Then, use vgextend to add it to an existing VG: vgextend test-volume/ dev/ hda2. 然后,使用vgextend将它添加到现有的VG中:vgextendtest-volume/dev/hda2。
The user commands mkvg, chvg, and lsvg have been enhanced in support of the scalable VG type. 对用户命令mkvg、chvg和lsvg进行了增强以支持可扩展VG类型。
The classical concurrent mode volume groups ( VGs) only supported Serial DASD and SSA disks in conjunction with the32-bit kernel. 经典并发模式卷组(VolumnGroup,VG)仅支持串行DASD和SSA磁盘以及32位内核。
Select the client machine ( server to be updated), type the disk which the TL will be applied& since this is going to be a alternate disk, make sure the disk is not used by any other volume group ( VG). 选择客户端主机(将要更新的服务器),输入将要应用TL的磁盘&因为它将会成为一个备用磁盘,要保证这个磁盘没有被任何其他卷组(VG)使用。
This VG has enough capacity to cater for a full copy of the NIM clients root volume group ( rootvg). 这个VG的容量足够容纳NIM客户机根卷组(rootvg)的一个完整副本。
Select the nodes appropriately to create a VG. 选择要创建VG的节点。
Volume groups ( VGs) are made up of disks ( hdisks) called physical volumes ( PVs). 卷组(VG)由称为物理卷(PV)的磁盘(hdisk)组成。
This VG will be empty until the migration is started. 在迁移过程开始之前,这个VG将是空的。
A scalable VG allows a maximum of1024 PVs and4096 LVs. 一个可扩展VG支持最多1024个PV和4096个LV。
The PVs and the VG are created in a single step: vgcreate 在一个步骤中同时创建PV和VG:vgcreate
If the VG and FS were created using CSPOC, the definition will be imported to all the cluster nodes automatically. 如果使用CSPOC创建VG和FS,定义会自动地导入到所有集群节点。
It also passes the concerned disk name and volume group name in the DISK_NAME and VG_NAME fields. 它还会在DISKNAME和VGNAME字段中传递相关的磁盘名和卷组名。
Different extent sizes means different VG granularity. 不同的区段大小意味着不同的VG粒度。
Install IBM HTTP Server on the shared disk/ VG ( ihsvg) of fallover/ failover/ standby/ standalone node or on the same node depending on the requirement. 在故障转移/备用/孤立节点的共享磁盘/VG(ihsvg)上安装IBMHTTPServer,或者根据需求在同一节点上安装。
Note that the initial-ramdisk image usually activates LVM only when it detects that the root filesystem is under a VG. 注意,通常只有当探测到根文件系统在一个VG中时,initial-ramdisk映像才会启用LVM。
These are a set fixed size at the VG layer. 在VG层,这些PP有固定的大小。
With LVM, you can remove a PV from a VG in the same way they are added ( that means online!). 在使用LVM时,可以按照添加PV的方式从VG中删除PV(即在在线情况下执行删除)。
Each VG must have at least one PV, and only one VG can be assigned to a PV at a time. 每个VG必须有至少一个PV,而且任何时候只能给PV分配一个VG。
Subsequently, a new VG type was introduced which was referred to as big VG. 随后引入了一种新的VG类型,即大容量VG。
Be aware, however, that different extent sizes can't be mixed in a single VG, and changing the extent size is the single unsafe operation with the LVM: It can destroy data. 但是注意,在一个VG中不能混用不同的区段大小,而且用LVM修改区段大小是一种不安全的操作,会破坏数据。
This includes the capability for LVM to restrict a volume group ( VG) to only contain SSDs and the ability to report that a VG only contains SSDs. 这包括LVM能够把卷组(VG)限制为只包含SSD,能够报告只包含SSD的VG。
VGs ( normal, big, and scalable) VG(常规、大容量和可扩展)
You can use the lvmo command to display pbuf and blocked I/ O statistics and settings for pbuf tunables, regardless of whether the scope of the entity is system-wide or VG-specific. 您可以使用lvmo命令来显示pbuf和阻塞I/O的统计信息和pbuf可调参数的设置,不管该实体的范围是系统范围还是VG特定的。
The target VG can be online! 目标VG可以是在线的!
Above the physical volume ( PV), three other cylinders are grouped by an ellipse showing how they together represent a volume group ( VG). 除了物理卷(PV)之外,其他三个柱面是按椭圆形进行分组的,它们显示了如何将三个柱面组合在一起表示磁盘组(VG)。
A single volume group ( VG) was created that spanned all eight volumes. 创建了一个跨越所有8个卷的卷组(VG)。
Once they are mounted, they can be dynamically grown, shrunk, or modified, and adding more space to the VG is as simple as adding another PV. 加载VG之后,就可以动态扩展、缩小或修改它,而且向VG添加更多空间与新增一个PV一样简单。
The examinations of hepatic function, hepatic tissue stained by HE and VG, double in situ hybridization of albumin and Y-chromosome were performed at the30th day postoperatively. 术后30天活杀小鼠进行肝功能、肝组织HE染色和VG染色、肝组织Y染色体和白蛋白双重原位杂交等检查。
