Mount points vs. drive letters....

  • What are peoples' opinions of mounting drives as folders (i.e. mount points) as opposed to assigning drive letters? Anyone encounter any problems?

    Not that I expect that anyone would run out of drive letters, but just a thought that popped into my head.

  • I would be curious to know how you do these mount points. Is something you do in SQL Server?

    In any case, the last time I had to deal with a similar problem was when an ASP page executed a query and had to do a save of the ADO result set to a share which required a user and password to access. I never found a way to access this share without mapping it to a drive using WScript.Network's MapNetworkDrive method. But before doing so, the code would scan all existing mapped network drives to see if it's already mapped, etc. etc.

     

  • ...Not that I expect that anyone would run out of drive letters...

    - consider a cluster-node with a couple of instances topology driv1-data1 drive2-data2 drive3-log drive4-backup .... You'll run out of driveletters soon enough

    - I've mounted the backupvolume in a folder of the logdrive for some of our instances.

       Just to keep a reminder, this mounted-directory is named MOUNTED_bu,

       so it leaves a trace everywhere it is being used or may be used.

  • Funny you should mention a cluster with multiple instances. That's something I've been tasked with investigating as part of a consolidation project, hence why it popped into my head.

    Good point re: naming the folder.

    Michael:

    No, it's something you do in the OS. In Disk Mgmt, instead of assigning a drive letter to a drive, you can mount it to a folder on an existing drive. So you see an extra folder on your C: drive, say, rather than seeing a D: drive. Note: only works with NTFS. Search for "mounting partitions" in Windows help. Works in Win2K & Win2K3.
