This blog is part of my Scaling Out Search Series and describes the processes for adding a new crawl component to a new search server:
Get Search Service Instance and Start on New Index Server$ssi = Get-SPEnterpriseSearchServiceInstance -Identity "<<new index server>>"
Start-SPEnterpriseSearchServiceInstance -Identity $ssi
Wait for Search Service Instance to come online
Get-SPEnterpriseSearchServiceInstance -Identity $ssi
(The full script contains a loop that waits for the service to come online)
Clone Active Search Topology$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone –SearchTopology $active
Add New Crawl Component
New-SPEnterpriseSearchCrawlComponent -SearchTopology $clone -SearchServiceInstance $ssi
Activate the Cloned Search Topology
Set-SPEnterpriseSearchTopology -Identity $clone
Review new topology
Get-SPEnterpriseSearchTopology -Active -SearchApplication $ssa
Monitor Distribution of Index
Get-SPEnterpriseSearchStatus -SearchApplication $ssa
(The full script contains a loop that waits for the index component to be Active)
The new index component will be "Degraded" until the index is fully synced. Use the -text parameter to retrieve more detailed information:
NEXT, I created a New Content Processing Component.

This is cool!
ReplyDeleteThis post is awesome. I learned a ton. Thanks Steve.
ReplyDeleteNice One
ReplyDeleteFantastic. This saved my life. you are excellent :)
ReplyDeleteWhen you add a new crawl component does that replace the existing one on a server? I don't see anything happening to remove the component first? I have a crawler with a red X on it so need help to fix it
ReplyDeleteCannot be copied from the Full Script above, brings over various weird characters like รข€
ReplyDeletepaste into notepad first to remove any browser characters
