hii am working on a linux server and have a temporary SAN disk 55G LUN mounted...
how can i know the amount of disk space on it??

its mounted as /mnt/testdata

firing df -H doesnt show any disk mounted on that place...

plz let me know...

Then you don't have a drive mounted at that location. Your files are probably going into that directory, not onto the SAN.

Linux will just see a SAN disk as just another SCSI disk, nothing special.

but then i can acess that location using cd command, move copy delete files from der...

Right. That location is nothing more than a directory. Read my previous post...chances are, your files are just getting copied to local disk, into that directory, not to the SAN.

sir but why cannot i see the disk space of testdata mounted on /mnt .. is there any oder command, i have being figuring this out for 2 days now..

and thanks a millions for such informational website.. thanks

Ok...this is the THIRD TIME:

YOU CAN'T SEE IT, BECAUSE IT'S NOT MOUNTED. You DO NOT have the SAN volume mounted to that mount-point.

Type in "mount". You should see the SAN device listed...if you don't, it isn't mounted, period. There's nothing else to do, other than mount it.
