Welcome
Windows 2008 R2 + SQL 2008 R2 SP2 CU13
2 days after creation of snapshot for database (650 GB in 10 files)
file fragmentation (files with indexes) are so big that sql engine throws errors Operating system error 665(The requested operation could not be completed due to a file system limitation) encountered.
We have also diskeeper in place
Database snapshot 'xxx' has failed an IO operation and is marked suspect. It must be dropped and recreated.
Is there any patch for this ?
What mean below ? I see that snapshot files are big as database files. WHat need to do in this case ?
A mitigation strategy is to divide the database into a few more files. The limitations are per sparse file and each database snapshot creates matching sparse files for each database file. For example if the database files are each limited to 64GB in total size, you can't exceed the limitation on a per file basis.
