windows associates the drive mappings w/ a user session. Since the agent isn’t using a user session, it can’t see the drive. This is a windows limitation, not a bladelogic one.
if the disk appears as local disk – SAN, iScsi, then it should work fine. the question w/ iscsi is can many targets have concurrent access to the same file system?
That certainly explains the behavior I am seeing. So I guess NAS is out.
You can have multiple systems mount the same LUN over iSCSI, however, you then have multiple servers with block level access to the same disk. This is very bad, unless you have a cluster-aware file system, in a cluster, which facilitates communication between the servers to keep them from stepping on each others toes.
I'm not sure if MS has a Cluster File System that will allow multiple servers write access to the same LUN. I know Vertias Cluster Server would work, but it isn't cheap.
I guess the lesson to be learned here is stick with Linux/UNIX
you could stand up a linux box or two to use as the file server and do the nfs thing.
In our whitepapers, best practices ect... we state that if you are using a mounted drive, regardless of windows or linux, on each individual app server, that the fileserver configuration is actually to localhost... since its the same mount point regardless of the app server.
This type of configuration is in place a slew of customers. You need to get over the windows issue of drive mounting, but if you can do that, the rest is pretty much the same.
Thanks for the input Ben. This is exactly the configuration that I am going for. Mount the same drive in the to the same location on all app servers, then configure the file server to be localhost. However, I can't seem to "get over the windows issue of drive mounting". I would love to hear if others have been able to do this with a Windows application servers and if so, how did they get around the "windows issue of drive mounting".
Use linux… ☺
were you able to get it working with windows? i am running win 2k8 R2 and would like to setup NAS. thanks
