SQL Server Indexing Errors with message that should not apply

[JHizzle]

We have a maintenance plan set up to run on a set period taht includes indexing the databases. For some reason, the index tasks is faling with the following:

Failed:(-1073548784) Executing the query "ALTER INDEX [PK_redactedname] ON [dbo].[tblredactedname] REBUILD WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, SORT_IN_TEMPDB = OFF, ONLINE = ON )
" failed with the following error: "Online index operation cannot be performed for index 'PK_redactedname' because the index contains column 'redactedfield' of data type text, ntext, image, varchar(max), nvarchar(max), varbinary(max) or xml. For non-clustered index the column could be an include column of the index, for clustered index it could be any column of the table. In case of drop_existing the column could be part of new or old index. The operation must be performed offline.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

I'm not an expert so I could be reading this wrong but the field that it's referring to...is not an identity field nor is it indexable so why is it trying? The message code is unfortunately too generic judging from google fu. I've tried looking around to see if there's a setting I need to override so that it doesn't try to index this table but to no effect. Can anyone offer some pointers?

Can you delete the PK_redactedname key and/or remove the index. If the key/index does not exist then look into the sysobjects meta data or the system views, you may have a left over entry that needs removing.

Never underestimate the power of human stupidity RAH

Thanks for the reply, in the end the index itself was marked as being clustered to include fields that were text ones.
