请问改变数据库的LOG文件名为什么出现这个错

[iemis]

当我用这个时DBCC REBUILD_LOG ('DB1', 'F:\DB1\DB3_Log.LDF' )
出现如下错误
Server: Msg 3624, Level 20, State 1, Line 1

Location: filemgr.cpp:1890
Expression: fcb->GetSize () < fileSize
SPID: 51
Process ID: 972

Connection Broken
但是在F:\DB1下还是会产生一个DB3_Log.LDF'这个文件，不过数据库还是不能使用。
请高手指点指点

建议先把数据库分离出来再改名

数据库的sysindexes表坏掉了怎么修复，我用在DBCC CHECKDB(‘DB1’)出现如下错误
Server: Msg 8966, Level 16, State 1, Line 1
Could not read and latch page (1:58418) with latch type SH. sysindexes failed.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
现用这句dbcc checktable ('sysindexes',REPAIR_ALLOW_DATA_LOSS)
就出现如下错误
Server: Msg 3908, Level 16, State 1, Line 1
Could not run BEGIN TRANSACTION in database 'DB1' because the database is in bypass recovery mode.
Server: Msg 8966, Level 16, State 1, Line 1
Could not read and latch page (1:58418) with latch type SH. sysindexes failed.
但只有部分表的内容在紧急模式下可以SELECT，是不是这样这个MDF文件就没法了啊

数据库的sysindexes表坏掉了,你用dbcc checkdb('DB1'),查一下数据库的怀况
