Prevent other apps from starting if drive missing

[vegasit]

Is there any way to prevent other apps from staring if there is a missing drive in DP? I have a dedicated server that runs drive pool with 40 drives. The apps that run use and monitor them for content, however when a drive "falls out" then and the other app scans it just sees the content as missing and tries to re-acquire the content. But this creates a lot of "extra" data usage as they are not really missing, its just the disk that the content is on is missing (usually temporary)

If a disk in the pool goes missing then the pool should automatically change to read-only until the disk returns; we can test for that with a simple batch file. For example if the app was "c:\bin\monitor.exe" and your pool's drive letter was "p" then you could create an empty file called "testreadable.txt" in the root folder of your pool and create a batch file (e.g. "launchapp.bat") containing one line:

COPY /Y p:\testreadable.txt p:\testwritable.txt && "c:\bin\monitor.exe"

Launching that batch file would only result in launching the app if the file p:\testreadable.txt could be copied over to p:\testwritable.txt - which would indicate the pool was writable (all disks are present).

Note that this doesn't help if a drive goes missing while the app is already running. You'd need something more for that.
