当我运行Get-ClusterStorageSpacesDirect命令时,我收到以下警告：
WARNING: 2018/01 / 16-11: 11: 38.574 Node DB1: No disks found to be used for cache WARNING: 2018/01 / 16-11: 11: 38.580 Node DB2: No disks found to be used for cache CacheMetadataReserveBytes: 34359738 CacheModeHDD: ReadWrite CacheModeSSD: WriteOnly CachePageSizeKBytes: 16 CacheState: Enabled State: Enabled
我注意到,当我复制文件时,我只能达到80 – 90 MB之间的速度
为什么我得到的错误是没有为缓存找到磁盘但是CacheState和State是否已启用？
这可能是复制速度只有大约90 MB的原因吗？
谢谢您的帮助
1)备份您的数据.
2)禁用S2D调用Disable-ClusterS2D cmdlet.
3)清洁磁盘.您需要从此处运行脚本：
icm(Get-Cluster -Name | Get-ClusterNode){
更新StorageProviderCache
Get-StoragePool | ？ IsPrimordial -eq $false | Set-StoragePool -IsReadOnly：$false -ErrorAction SilentlyContinue
Get-StoragePool | ？ IsPrimordial -eq $false | Get-VirtualDisk | Remove-VirtualDisk -Confirm：$false -ErrorAction SilentlyContinue
Get-StoragePool | ？ IsPrimordial -eq $false | Remove-StoragePool -Confirm：$false -ErrorAction SilentlyContinue
Get-PhysicalDisk |重置 – PhysicalDisk -ErrorAction SilentlyContinue
Get-Disk | ？数字-ne $null | ？ IsBoot -ne $true | ？ IsSystem -ne $true | ？ PartitionStyle -ne RAW | ％{
$_ | Set-Disk -isoffline：$false
$_ | Set-Disk -isreadonly：$false
$_ | Clear-Disk -RemoveData -RemoveOEM -Confirm：$false
$_ | Set-Disk -isreadonly：$true
$_ | Set-Disk -isoffline：$true
}
Get-Disk |？数字-ne $null |？ IsBoot -ne $true |？ IsSystem -ne $true |？ PartitionStyle -eq RAW | Group -NoElement -Property FriendlyName
} |排序-Property PsComputerName,Count
5)重新启用S2D调用Enable-ClusterS2D cmdlet.
6)恢复您的生产数据.
这应该可以解决问题.
附：在将双节点S2D集群投入生产之前要三思而后行：恢复能力并不存在,它不能承受连续第二次磁盘故障,或者在一个节点停机以进行修补或任何其他情况下的任何(节点或磁盘)故障.微软最初启动S2D有4个节点是有充分理由的,VMware vSAN在这里与S2D在同一页面上.
