创建新索引组件并将其添加到克隆拓扑？

Question

我在搜索服务应用程序中爬行包含480k项目的文件服务器。 SharePoint Server只有一个具有20 GB可用空间的系统磁盘，并且没有其他服务器可用。在爬行文件服务器时，系统磁盘熄灭空间，因为默认索引文件夹位于C-drive上。我们停止爬行，执行索引重置，并再次运行搜索服务应用程序，但索引组件被打破（在搜索管理页面上检查，并通过PowerShell）。

我们已订购一个新磁盘，用于爬行文件服务器，但尚未使用。我们正在尝试在本地SharePoint内容上进行全面爬网，这是小的），但爬网永远不会结束。可能是因为索引组件不可用。

我有两个选项：

• 删除当前的搜索服务应用程序，然后从头开始，再次重新创建它。
• 创建一个新的索引组件，克隆活动拓扑，将新索引组件添加到克隆（删除损坏的一个），并将克隆拓扑设置为活动的拓扑。

  但我没有找到创建新索引组件的方法。是否有可能？

As it turned out, this was not an easy task.

Clone Search Topology

At fisrt I tried clone the search topology, replace the failing Index Component, and activate the clone topology - like this following the technet guide Manage the index component in SharePoint Server 2013:

if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null) 
{
    Add-PSSnapin "Microsoft.SharePoint.PowerShell"
}

$hostA = Get-SPEnterpriseSearchServiceInstance -Identity "SharePointServerName"

# If the Search Service Instance isn't started, run the following command
#Start-SPEnterpriseSearchServiceInstance $hostA

# Wait for ONLINE status, check by using this
#Get-SPEnterpriseSearchServiceInstance $hostA 

# When ONLINE, make a clone
$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone -SearchTopology $active

# Create a new Index Partition (0) - outputs IndexComponent2
New-SPEnterpriseSearchIndexComponent -SearchTopology $clone -SearchServiceInstance $hostA -IndexPartition 0

# Verify that the search service application is running. False=Running, True=Paused
$ssa.IsPaused() –ne 0

# Set the clone as the new topology (takes a while). If Index component is Degraded, this will run with no end
$ssa.PauseForIndexRepartitioning() 
Set-SPEnterpriseSearchTopology -Identity $clone

However, having an degraded index component made this action impossible. Reference: SharePoint 2013 Unable to change topology when Generation controller is not active

Create a new Topology

Next step, make a new, fresh topology (using this technet guide: Change the default search topology in SharePoint Server 2013).

if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null) 
{
    Add-PSSnapin "Microsoft.SharePoint.PowerShell"
}

$hostA = Get-SPEnterpriseSearchServiceInstance -Identity "SharePointServerName"

# If the Search Service Instance isn't started, run the following command
#Start-SPEnterpriseSearchServiceInstance $hostA

# Wait for ONLINE status, check by using this
#Get-SPEnterpriseSearchServiceInstance $hostA 

# When ONLINE, make a new topology
$ssa = Get-SPEnterpriseSearchServiceApplication
$newTopology = New-SPEnterpriseSearchTopology -SearchApplication $ssa

# Create new components (one server only)
New-SPEnterpriseSearchAdminComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchCrawlComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $newTopology -SearchServiceInstance $hostA

# Set the Admin Component without index
set-SPEnterpriseSearchAdministrationComponent -SearchApplication $ssa -SearchServiceInstance  $hostA

# Remove temp Index files, and recreate the folder
$IndexLocation = "C:\Index" # Change to another disk than system disk
Remove-Item -Recurse -Force -LiteralPath $IndexLocation -ErrorAction SilentlyContinue
mkdir -Path $IndexLocation -Force 

# Create new index component with a frech index folder
New-SPEnterpriseSearchIndexComponent -SearchTopology $newTopology -SearchServiceInstance $hostA -RootDirectory $IndexLocation -IndexPartition 0

# Activate the topology (either one of the following works)
$newTopology.Activate()
#Set-SPEnterpriseSearchTopology -Identity $newTopology

Up on activation, I got a conflict and failed again.

Exception calling "Activate" with "0" argument(s): "Topology activation failed. An update conflict has occurred, and you must re-try this action. The object Repartition
Info Name=RepartitionInfo was updated by DOMAIN\SPFarm, in the OWSTIMER (11712) process, on machine SharePointServerName.  View the tracing log for more information about t
he conflict."

Delete current failing Search Service Application

This should be easy, just use Central Administration > Manage Service Application, select the Search Service Application and click delete-button in the ribbon. Failed, again.

In order to make this to work, you need to stop the sptimerv4...

>net stop sptimerv4

... and delete cache files located in \ProgramData\Microsoft\SharePoint\Config\{Guids Folders} where cache.ini is located. CAUTION: Don't delete the cache.ini-file. Just edit the file and use another six digit random number. When you're done, start the service again. Reference: An update conflict has occurred, and you must re-try this action.

>net start sptimerv4

And finally the ribbon delete-button works. You're failing Search Service Application is gone. Now (finally) you can create a new Search Service Application, with a fresh topology and a working index component.

Answer 2

I had the exact same issue as you described where the index component was broken after an Index Reset.

I was ready to roll my sleeves up and work through your detailed steps (thank you by the way) when I resolved it by using the Pause/Resume option.

Why did I try Pause/Resume? Well after I did an IISRESET I found that the Content Sources were stuck on "Paused". Thus I toggled the Pause/Resume option and miraculously it fixed the index component.

EDIT: This was a temporary fix. In the end I had to rebuild the Search Service Application from scratch.

Answer 3

Try this through Powershell:

$hostA = Get-SPEnterpriseSearchServiceInstance -Identity "myserver1"
$ssa = Get-SPEnterpriseSearchServiceApplication
$topology = Get-SPEnterpriseSearchTopology -SearchApplication $ssa
New-SPEnterpriseSearchIndexComponent -SearchTopology $topology -SearchServiceInstance $hostA -IndexPartition 1
