Jul 13, 2007Hi everyone,
Due to running out of disk space and reducing I/O contention, I plan to seperate data files and log files to different disk arrays.
My plan is to
- detach all databases
- copy log files to another disk
- attach all databases
The total size of log files is about 60GB. It becomes a problem becasue it spend too much time passing files. To reduce down time, is there any way I can do?
Can I just create new log files and remove the current files by using sql management studio?
any other suggestions? Thanks in advance
Calculating COUNTER Physical Disk: AVG. DISK QUEUE LENGTH
Sep 10, 2007If I return the Average, Minimum, and Maximum values for the counter Physical Disk: Avg.

Should The Quorum Disk Be A Physical Disk Or Majority Node Set?
Nov 15, 2006Hello,
I am trying to setup a test cluster and am having an issue. When I try to create the resource of a physical disk it takes both the drive e: and drive q: and doesn't seperate them into two physical disks as resources. This means when I try to associate the quorum disk it links the to physcial disk resource of drive e and q. Then when I try to install SQL2k5 I get the warning about installing SQL on the quorum disk. Am I missing something? Is there a way to seperate e and q onto two physical disk resources so I can specifically associate the quorum to q and the sql to e or should I be setting the quorum disk to a majority node set? Thanks in advance.

Disk Crash Of Disk That Contains The Paging File.
Feb 20, 2001Hello,
this is my configuration :
1) 3 disks in RAID5 that hold the SQL data
2) 1 disk in RAID0 that holds the only paging file.
What will happen to the SQL data (DB) when the disk that holds the paging file crashes?

SQL Server, Disk Arrays And Disk IO
May 7, 2004Hi all,
Ok here goes,
I have a three tier system using SQL server 2000, we are currently experiencing IO bottle necks on our SCSI Raid 10 array, which holds the Data and the logs in separate partitions.
So my options as I understand it are:
Get Enterprise edition
or
Get another physical raid 10 array and separate the logs and data i.e. data on one array and logs on the other array.
I would like to try the latter but I am totally unsure how much difference this will make or whether it will make any difference at all.
Does anyone know how much performance increase I will get from using two arrays as opposed to one?
Any other advice on this scenario would be greatly appreciated.
Thanks

Feb 19, 2001Hi All,
I have a server and it has C: D: F: I: Drives and all the system files are on C:Drive and and all the .MDF's and .LDF's(model,temp,master) are on the F: Drive and now I am running out of space on both(C: and F: Drives)
1. Can we add space to the C: and F: drives on the fly?.
2. Can I move the System databases ( MDF's and LDF's to some other drive)and if so, how do I do it?( Moving the databases ) and this is on the production database so when I have to do this.Will there be any impact.
Thanks in Advance,

Disk Space
Feb 21, 2003Does anyone know how to get the free disk space for all drives in many different SQL servers.
I need to populate a report (right now output in Excel) with the free disk space of all drives on all of my SQL servers.
I found xp_fixeddrives but that is specific for the server where it is executed.
Any help or pointers to a script in the archives is much appreciated.
Thanks.
Disk Fragmentation && SQL

SQL 6.5 And Disk Cloning
Mar 23, 1999We need a drive cloning app, like Ghost, that will allow us to transfer a production image off of a HDD to other PCs. The problem with this is that
our production needs SQL in order to run and transferring the initial image to uniquely named workstations causes DB registration problems. Is there
an app that will allow us to configure this transferred image so that SQL will refer to the "new" drive instead in of the "old"?

Low Disk Space On C:
Aug 2, 2004I noticed something strange today. I was running a query using query analyzer on a large database (8.8 million records) and the disk space on the c: drive was dropping and eventually went to 0. Availalbe space on the c: drive is 10GB. The query did complete. SQL server and all the databases are on the d: drive. After closing the query results in query analyzer the disk space returned. Is this a concern and is there a way to change it to use the d: for whatever it is doing?

Aug 9, 2004What's the best way to find out if disk fragmentation on Windows 2000 Server is affecting SQL Server performance?
If disk fragmentation is shown to be a cause of performance problems, what are the recommendations for a disk fragmentation strategy? eg. use the win 2000 built in disk defrag utility or buy a 3rd party product like DiskKeeper? How much of an overhead is a product like DiskKeeper that defrags in the background?

DTS Disk Space
Jun 30, 2006This is my first attempt using SQL 2000 and DTS. I am importing an Access database using the DTS wizard. The process fails with a "Not enough space on temporary disk" error. There is definitely enough space on the physical disk. I don't have any limits on any folder sizes either. What "disk" is the error talking about, and how do I give it enough space. The database is relatively small, about 10MB. I believe the database was created using Access 97. Please help.

Oct 30, 2007I understand the log files (LDF ) and data files (mdf ) should be on a different drives . I believe it leads to greater availabilty and speed . Are there any other reasons for to keep this on a separate drive.
Also what considerations I should take care while creating a database of around 100 GB . (use of filegroups , growth % etc ). Is there any connection of number of users to number of disks SQL data file to be spread to . Also do I need to take care (through hardware / software for a Quad core CPU ) to take full advanage of Quad core CPU.
Normal Disk IO
Apr 15, 2008I am wondering what normal disk I/O should be.
i know it verys depending on use but im looking for an average.
here is an idea of what we have
there is about 10 centers doing replication to our primary server.
we have about 80 users connecting directoy to our primary server using MS Dynamics through CITRIX.
we have a few other apps use the database as well however i am fairly certin its Dynamics generating our disk IO
Hardware wise we have a powerful blade connected to a raid 5 SAN with 15000 rpm disks.
normaly the disk IO stays fairly low but every so often it goes crazy and im thinking it shouldn't
Below is a sample of our disk IO from perfmon over 2 minutes or so. as you can see everything looks ok untill 04/15/2008 10:12:49.470 when the Disk I/O % goes above 100%

Quorum Disk Again.
Jan 18, 2007Hi,
I'm trying to install a server cluster to implement an SQL Server 2005 cluster. No other services (I think this is important).
I've a dual SCSI channel Smart Array with 4 disks configured in a 400Gb RAID 5.
I do not need to move different resource groups from one node to the other, I need only one group with all the resources IP, Network name, MSDTC, and SQL Server..., when a node fails, all services should failover to the other node.
Is it possible to have only one physical disk (RAID 5) for Quorum disk and shared disk?
It would be the following configuration:
[Groups]
Cluster Group
IP Address
Network Name
Physical disk (used for quorum and shared storage)
Distributed Transaction Coordinator
SQL Server
SQL Server Agent
Generic Service (SQL Server Fulltext)
The other option would be having a 1 physical disk Raid 0 for Quorum (146Gb wasted) and another physical disk Raid 5 (3 disk) for Shared Storage, but this schema will have a a flaw point that if Quorum disk fails, the cluster fails....
Any help would be appreciate.
Best regards.
Ilde.
Recovery From LOG Disk Failure
Dec 30, 2004I am writing up a general purpose document regarding Disaster Recovery and Backup and Restore, etc. I have a question that I've been unable to find any definitive answer on, and I was hoping that someone might have an answer.
Here is the scenario and what I have so far, and my question:
Scenario - A simple database, with one MDF and one LDF, each on it's own disk, with no mirroring or filegroups etc.
Disaster - the LOG disk fails.
To simulate the disaster, I shut down SQL Server, and delete the LDF manually.
When I restart SQL Server, the database is marked as suspect. As expected :)
So, now the recovery begins..... I've read that in this case there is no data loss, but I find that hard to believe. Can anyone confirm?
Anyway, how to restore the database to usable status? Here is what I've come up with so far:
1) Do a backup of "the tail of the log." This works even though there is no log. I have no idea why really, but I can't proceed otherwise.
2) Detach the database.
3) Reattach the database. This auto-creates a new log file (albeit not in the location I want, which makes for more work after).
At this point the database appears to be fine. I have not seen any lost data or problems, but of course I'm working on a test database, not with live users hitting it constantly. If the database were under heavy use, I expect that there might indeed be data lost?
Is this the recommended way to recover from a disaster of this type? Or, would it be better to just go back to your last good backups and forget about "up to the minute" recovery in this case? Or is there yet another means?
Thanks,
Travis
Find Disk Space
Feb 21, 2002I need a way to get the used space for a physical drive, or even the total capacity for a drive to do some calculations.
I don't want to have to write my own native code either.
Is there a stored procedure that will give this to me?
I saw the xp_fixeddrives that will give the free space, but I need one of the other as well.
Any way to get this?
Thanks,
Jason
Evaluating Disk Space
May 9, 2000We recently moved from v6.5 to v7.0. Now I have the databases and logs set to "autogrow". How can I monitor the disk space to ensure I do not run out of room (or is that preset as to how large it can grow ?). Can't find anything in the books online. Do I do this through the NT admin tool or through the SQL*Server Enterprise Manager and more importantly - how ???
Thanks so much for any help...

Insufficient Disk Space
Feb 19, 2001I'm trying to save a dts package and it keeps coming back with insufficient disk space. I noiticed that db MSDB was full so I manually increased the size. It was set to manually grow at 1 mb increments. But for some reason it didn't look like it was doing that so I manually increased it. Right now this is about 355 MB free so that should be plenty to save a package. But its still coming back with the same error insufficient disk space to complete operation. Any ideas on why or why it didn't grow on its own? Please help I can't seem to save any packages.
View 1 Replies View RelatedDisk Dump To Another Machine
May 12, 2000We are trying to set up a disk dump to another machine (our backup SQL machine). I mapped a drive to the other machine
but it only sees the local drives when I try to create the dump device. I typed in the path, but I
get error messages stating that it can't open the file when I try to do a dump. From what I have read, I thought I could
do a disk backup to another machine. Am I trying to do something impossible? Any help would
be appreciated. Thanks.
2 Servers 1 Disk Drive
Sep 10, 1999I've been asked to configure a "hot-backup" server configuration.
However, I'm coming into the situation a bit later, and they would like me to accomplish the hot-backup with their hardware and their methodology.
Here goes.
We have two identical servers. They will both have a SCSI connection to a device refered to as an "EMC". It will be seen as a single drive letter "E:" to both boxes. Only 1 server will be "up" and using the drive at a time.
The idea is to have SQL devices - (oops, database files) located on the "EMC" drives and in the event of a failure of one server, we bring up the backup and it will take right off using the existing Database files (*.mdf, *.ldf files).
1. Can Sql server 2 come up using databases that have been modified
by server 1. (Provided Master database is on this common drive?
2. What about MSDB, can it be located on a drive different than
where SQL program files are located?
3. How about installing all of SQL application and DB's onto
the Shared Drive? Can a different server come up using the same files?
Anyone out there done/seen/heard of a similar configuration?
Any caveats
Recovering Disk Space
Feb 2, 2000Our database -SQL Server 7.0 sp1 (NT 4.0 sp5)- is growing at a very fast rate despite the fact that we are deleting old record. It doesn't seem to be recovering disk space for the deleted records. Please let me know if there is a specific setting that can help us recover disk space. )

Sep 28, 1999Hi,
I am trying to create a scheduled task taht will restore a database from a backup file. I do not store my backups on a backup device, but on a local disk. To restore a DB from a backup device, the following statement will work:
"Load DBName from BackupDeviceName". Does any know what statement to use to restore from a file, if the file is "E:DBName_db_dump_199909272220".
Thanks in a advanced.
Moving LogFile From One Disk To Another
Apr 11, 2002I am trying to move a logfile from one disk to another. I've detached the database, moved the logfile to another disk and reattached the database. I used the sp_detach and sp_attach_db to specify the paths of the *.MDF and *.LDF. I've tried it through Enterprise Manager and with boths ways I get an error message saying: "Error 9003: The LSN (201:48:2) passed to log scan in database 'DatabaseName' is invalid". Does anyone know what this means and how I can get around this. I've even tried to attach the database with the logfile in the original path and I still get that error. Need Help Please!
Thanks
