I try to save my database ≈ 260 Mb
I have this error :
System.Data.SqlClient.SqlError : failure read function incorrect
So I try :
DBCC CHECKDB ('myDatabase') PHYSICAL_ONLY
I have this error :
Msg 8921, Level 16, State 1, Line 1 Stop control. An error occurred
while collecting the facts. Insufficient space in tempdb or
inconsistency of a system table. Check out the previous errors.
I have same error without PHYSICAL_ONLY but the rest seems normal
DBCC CHECKDB ('myDatabase') WITH ESTIMATEONLY :
9357520 Kb => 9 357,52 Mb
SELECT SUM(unallocated_extent_page_count) AS [free pages],
(SUM(unallocated_extent_page_count)*1.0/128) AS [free space in MB]
FROM sys.dm_db_file_space_usage;
free space in MB : 30 389 Mb
DBCC SQLPERF(LOGSPACE)
tempbd :
– Log size : 13 299 Mb
– Space Used (%) : 0.01%
I do not know why this does not work
Edit : When I try xcopy (database offline) I get this error :
target volume does not support symbolic links
Best Answer
is it a physical or a virtual server? Please make a chkdsk on your filesystem where the database are stored.
Please also try a BACKUP DATABASE with CONTINUE_AFTER_ERROR:
