Cluster Drive Slow To Restore
Jan 22, 2008
Hi
I have configured a cluster SQL 2005 (active/passive) and added 4 LUNS to that cluster the cluster works without problems.
However I am having issues backing and restoring on 2 drives. I can complete the operation ( a resotre of 100MB ) DB in less than a minute if i use the 2 drives but it takes about an hour if i use the other 2 drives. The wait type is ansynchronous_IOcompletion and backupthread in dm_exec_requests.
I have detached the drives and reformatted it but stil lsame issues any help

I've added a new drive to a clustered instance of sql 2000. Go to the node the instance is active on, the drive shows up. But...try to add a backup device that lives on the new drive (which was, after all, the whole point of the exercise) and SQL Server is blind to that drive. I have vague recollections of it recognizing the clustered drives when i set up all this a couple years ago. Could it be that it recognizes all the drives it'll ever recognize at the moment of installation? Anybody know?
thanks,
Garth

HI guys, long time since I've been here ...
Anyway, I have a question and hope to receive some suggestions.
We have a cluster installation of SQL 2000 Ent SP3a and we had a logical drive Y: on a second incative node: N2. SQL Right now is running of the active node: N1. We moved the Y: drive from Node N2 to the N1 one and it's fully functional and healthy. The only thing SQL doesn't see it. So ti has to be restarted.
Is there a way to refresh a list of logical drives on SQL without having the service to be restarted? (it's not an option for us meantime, it's our prod env.)
Any suggestions appreciated.
Thx

As part of a migration of data to a new SAN I have hit a bit of a snag in the migration. In summary what will happen is user database data files will be moved from one LUN (say drive F:) to a new LUN (say drive G:). Once all the data is migrated, plan is to remove dependency of that drive from SQL server and remove the drive and delete the LUN. So far, so good.
However one of the LUNs (drive D:) destined to be deleted also hosts the instance default directories, i.e. everything under MSSQL11.MSSQLSERVER (Data, Backups, FTData, JOBS, etc). BOL has articles on how to migrate system databases, including tempdb. But there is no guidance that I could find on how to relocate other folders. There are forums where users have listed registry changes, etc that can achieve this but these are steps I am unwilling to take on a production server.
So my plan is:
1) Add new drive to cluster (drive E:), sufficiently large enough to host instance default folders
2) Shutdown SQL server
3) Copy all default folders to new drive
4) Swap drive letters so that new drive is now D:
5) Start SQL server and if everything works, delete the original drive (which is now drive E:).

I'm trying to build a new cluster with SQL Server 2K Enterprise onWindows 2003 server. When I run the install, I tell it to put theprogram files on the D: (local) drive and the data/log files on shareddrives. However, after the installation is complete, almost all thefiles go in the C: drive in program filesMicrosoft SQL Server, ratherthan the D: drive (it does create a few files on D:). We've experiencedthis on more than one server build.Anyone know any way around this?Post answers publicly, please, or email tosteven.wechsler(at)mtvstaff.com (the posting email address is hosed).Thanks,Steve

Is there a way to get access to the files on the shared drive from either of the nodes when the SQL Cluster is shut down?
It doesn't look like there is, but hoping there is some trick. I see how it can be done with a Windows Cluster but not a SQL Cluster.

Our production database is located on one server, and our test database resides on another. Often, we need to restore the production dump to the test database. But the Restore Device from Server window doesn`t seem to allow references to dump files on a different server. I`ve tried using the Add Backup Disk File window to point to the remote location; but it doesn`t seem to save the reference when I close the window.
I`m sure there`s a way to handle this without copying the dump file from one server to the other.
This would seem to be a common scenario. Thanks for any suggestions that others have found useful.

From my workstation (with SQL Server 7 Desktop Edition SP3), I seem unable to restore a database on my Server (SQL Server Standard Edition SP3). I am logged into both machines, and I am an Administrator on both machines. Using either a UNC or Mapped Drive (see below)
RESTORE DATABASE ogAEC FROM ogAECDump WITH REPLACE , RECOVERY , STATS
, MOVE 'AEC_Data' TO 'Og-sqlsrvrC-DriveMSSQL7DataogAEC_Data.MDF'
, MOVE 'AEC_Log' TO 'Og-sqlsrvrC-DriveMSSQL7DataogAEC_Log.LDF'
RESTORE DATABASE ogAEC FROM ogAECDump WITH REPLACE , RECOVERY , STATS
, MOVE 'AEC_Data' TO 'Q:MSSQL7DataogAEC_Data.MDF'
, MOVE 'AEC_Log' TO 'Q:MSSQL7DataogAEC_Log.LDF'
I get
Server: Msg 3156, Level 16, State 2, Line 1
The file 'Og-sqlsrvrC-DriveMSSQL7DataogAEC_Data.MDF' cannot be used by RESTORE. Consider using the WITH MOVE option to identify a valid location for the file.
But I am successful if I run the essentially command locally from the server:
RESTORE DATABASE ogAEC FROM ogAECDump WITH REPLACE , RECOVERY , STATS
, MOVE 'AEC_Data' TO 'C:MSSQL7DataogAEC_Data.MDF'
, MOVE 'AEC_Log' TO 'C:MSSQL7DataogAEC_Log.LDF'
What can I do to be able to restore DBs from my workstation?

Hello all
as indicated by my stupid question, I am very new to sql. our vrsion is 2000 and I'm talking about in enterprise manager, the database that was created is not showing up in the list of db. Although I can see the file in explorer.
The problem I€™m having is when I try to attach the database €œmailarchive3Q2007_data.mdf€? it is also looking for the log file €œmailarchive3Q2007_log.ldf€? . The log file was removed by someone else off our system. I have a backup of the file but it is too large to restore now (160 gig) when the system was first set up the recovery model was not set to simple so the log just grew till it filled up our drive. I no longer have the drive space necessary to restore the log file and shrink it. So what do I do now? I need some kind of €œmailarchive3Q2007_log.ldf€? file to attach the database in enterprise manager.
Hope sombody can help.
thanks
Mike

Hello
we have two SqlServer 2005 in cluster. The machines act very slow (although the CPU load is low) as soon as we achieve one of these operations:
- drop / create database
- restore database
We achieve those operations through the SqlServer Browser or via sqlcmd.
Everything else is running smoothly.
Is there any known reason on why it can be so slow ?
best regards
Thibaut
(hope this is not too OT, but could not find any cluster-specific forum).

We are attempting to restore one of our databases from a backup that went to a local drive on the server.
We see the backupset in the list but receive an error that it is not available when we try to use it. When we try to restore from device and select the files the drive letter is not available. When we attempt to enter the path to the file it can't locate it. We don't have space on our SAN to copy the backup there and we can't add the local drive to the cluster resources.
Is there a way to get this backup done?

Has anyone else experienced this?
Database Restore takes much longer on Windows 2003 64-bit than on 32-bit...
Is this simply the Service Pack level or does it have to do with the 64-bit/32-bit issue?
We have a Development/QA/Production environment setup in this manner:
DEV - fast restores - (about 2 hours)
OS: Windows Server 2003 R2 Service Pack 2
DB: SQL 2000 Service Pack 4 (32-bit)
QA - slow restores - (about 10 hours)
OS: Windows Server 2003 x64 Service Pack 1
DB: SQL 2000 Service Pack 4 (32-bit)
Production - slow restores - (about 10 hours)OS: Windows Server 2003 x64 Service Pack 1
DB: SQL 2000 Service Pack 4 (32-bit)
Thank you for your time in advance!!!

This table has 1 clustered index based on its own unique record ID and that of its parent table record
I have an import process that adds appx 980 rows of data to this table and numerous rows to several other tables as part of a transaction and it ran in about 15 seconds.
However we suffered a server failure and it had to be rebuilt (Svr2k3), SQL 2000 re-installed (with default options) and the data base restored.
The same transaction is now taking 8 to 9 minutes.
I tracked it down to this particular table. Just doing a count(*) takes over 5 minutes. Select * where ID = 1 takes over 5 mins. Also, whenever the table is accessed you can hear the server thrashing the disks. Other tables, although smaller do not seem to be suffering from this masive performance drop..
I've tried droping and recreating the index. I have even created a copy of the table, with index, and still get the same issue with speed.
DBCC CHECKTABLE returns the following but takes 6 and a half minutes
DBCC results for 'TB_SAAI014_BPD'.
There are 3168460 rows in 72011 pages for object 'TB_SAAI014_BPD'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
No errors are shown
A DBCC CHECKTABLE on another table with 230 thousand rows, run at the same time only took 10 seconds
Can anyone please point me in the direction of things to check, try or repair.
Any help greatfully recieved.

Hi
I have been trying to use openrowset with a shared drive, and even though the share has "full control" permissions granted to "everyone" and the accout that SQL runs under has been granted explicit full control permissions I am unable to open the file which itself has no security on it.
Can I not use a \ path and only use mapped drives?
Thanks
below works...
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=C:5People.xls', [Sheet1$])
below doesn't work...
SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=\cluster02FileManager5People.xls', [Sheet1$])

I am trying to move a log file from one drive to another.
What I have done is add another file to my file group. So now my log has a file on the 'e' drive and one on the 'f' drive. I now want to remove the file on the 'e' drive. I have emptied the file on the 'e' drive. When doing the command:
ALTER DATABASE Uniprodruntime
REMOVE FILE m_rk_runtime_log
I get the following error message..
Server: Msg 5020, Level 16, State 1, Line 1
The primary data or log file cannot be removed from a database.
I have also gone into enterprise manager and tried to delete the file and it does nothing.
Has anyone run into this?

Being a very novice SQL Server administrator, I need to ask the experts a question.
How do I go about moving a database from 1 drive to another? The source drive (C is local to the server, but the target drive (E is on a Storage Area Network (SAN), although it is still a local drive for the server. I want to move the database from C: to E:. Can someone provide me with instructions?
Thanks,

I am in the process of moving databases from a SQL 2005 Standard version to a 2-node 2014 cluster.All of my 2005 databases back up successfully.They all restore without issue except for one database that has a full text catalog. I get this message

Access is denied to "fileStoragedataMSSQLSERVERFullTextCatalog", or the path is invalid.
Msg 3156, Level 16, State 50, Line 2
File 'sysft_FTCatalog' cannot be restored to 'fileStoragedataMSSQLSERVERFullTextCatalog'. Use WITH MOVE to identify a valid location for the file.

Problems were identified while planning for the RESTORE statement. Previous messages provide details.

I went as far as giving the folder full access to everyone temporarily and received the same error.
