RVC使用指南（三）-对象管理
https://mp.weixin.qq.com/s/B3wcxUP-QJRnb_kVIlbZqQ
看了就要关注我，哈哈~
本文介绍了vSAN中与对象管理相关的RVC命令。 这些命令用于故障排除或重新配置对象。
vsan.disks_info
vsan.disks_stats
vsan.cmmds_find
vsan.vm_object_info
vsan.disk_object_info
vsan.object_info
vsan.object_reconfigure
vsan.vmdk_stats
为了缩短命令，我对环境中的集群、虚拟机和ESXi主机使用了标记。这样可以在示例中使用~cluster、~vm和~esx来代替。
/localhost/DC> mark cluster ~/computers/VSAN-Cluster/
/localhost/DC> mark vm ~/vms/vma.virten.lab
/localhost/DC> mark esx ~/computers/VSAN-Cluster/hosts/esx1.virten.lab/对象管理
vsan.disks_info [-s] ~host
输出一台主机的物理磁盘信息，包括磁盘类型（SSD或MD），大小和状态。该命令可以识别磁盘是否适合用于vSAN。
-s, --show-adapters: Display adapter information in the state column.
示例1-在已启用HA的群集上禁用VSAN：
/localhost/DC> vsan.disks_info vSAN65/hosts/vesx1.virten.lab/

在只有UUID已知的情况下，显示vSAN中的对象或组件的信息。一个查找对象和对象详细信息的强大命令。可用于主机或集群， 建议针对集群使用，以将UUID解析为可读的名称。
-t, --type: CMMDS type, e.g. DOM_OBJECT, LSOM_OBJECT, POLICY, DISK etc.
-u, --uuid: UUID of the entry.
-o, --owner: UUID of the owning node.
类型：
DISK –represents a magnetic disk or flash device
DOM_OBJECT – represents composite objects
POLICY type – represents a policy
LSOM_OBJECT – represents a component

输出虚拟机的vSAN对象信息。此命令等效于vSphere Web Client中的“管理”>“ VM存储策略”选项卡，允许你确定虚拟磁盘的条带数，镜像和见证虚拟磁盘的位置。该命令包含以下信息：
Namespace directory (Virtual Machine home directory)
Disk backing (Virtual Disks)
Component layout (RAID-0, RAID-1)
Number of objects (DOM Objects)
UUID from objects and components (useful for other commands)
Location of object stripes and mirrors
Location of object witness
Storage Policy (hostFailuresToTolerate, forceProvisioning, stripeWidth, etc.)
Resync Status
用法：
-c, --cluster: Cluster on which to fetch the object info
-p, --perspective-from-host: Host to query object info from
-i, --include-detailed-usage: Include detailed usage info
示例1-输出DOM对象的物理位置和组件布局

使用新策略配置对象。要使用此命令，可以用vsan.cmmds_find或vsan.vm_object_info标识的对象UUID。
-p, --New policy: New policy
可用的策略选项有
hostFailuresToTolerate (Number of failures to tolerate)
forceProvisioning (If VSAN can't fulfill the policy requirements for an object, it will still deploy it)
stripeWidth (Number of disk stripes per object)
cacheReservation (Flash read cache reservation)
proportionalCapacity (Object space reservation)
注意保留现有策略。始终指定所有选项。必须以以下格式定义策略：
'(("hostFailuresToTolerate" i1) ("forceProvisioning" i1))'
示例1-更改磁盘策略以允许2个主机故障。当前策略为hostFailuresToTolerate = 1，stripeWidth = 1
/localhost/DC> vsan.object_reconfigure ~cluster 5078bd52-2977-8cf9-107c-00505687439c -p '(("hostFailuresToTolerate" i2) ("stripeWidth" i1))'示例2-禁用强制配置。当前策略为hostFailuresToTolerate = 1，stripeWidth = 1
