Or if the filesystem is not completely occupied it is possible to see occupying less space.
Is there any other way? Since the mount command as above suggested is asking me to specify the filesystem type which I gave as mount -t lvm /dev/nintendo/lvm1 /mnt -o ro gave following error mount: unknown filesystem type 'lvm' mount -t lvm2 /dev/nintendo/lvm1 /mnt -o ro gave following error mount: unknown filesystem type 'lvm2' mount /dev/nintendo/lvm1 /mnt -o ro mount: you must specify the filesystem type all the above three have given me errors. There does exist a filesystem but out of 100 Gb only 15 Gb are occupied in each case. Also It is a Dell Power Edge R710 server with 500Gb of hard disk.450Gb of which is available. and in this I have used 400 Gb to created the above LVMs I mentioned. -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
