Solution to insufficient folder space in the virtual machine operating system-partition and format the virtual hard disk and mount it to a folder

Partition, format, and mount a virtual hard disk to a folder...

Disk/dev/SDC doesn' t contain a valid Partition Table

[Root @ linux root] # fdisk/dev/sdb1 # Next, partition/dev/sdb1.

The number of cylinders for this disk is set to 4462.

There is nothing wrong with that, but this is larger than 1024,
And coshould in certain setups cause problems:
1) software that runs at boot time (e.g., old versions of lilo)
2) booting and partitioning software from other OSS
(E.g., DOS fdisk, OS/2 fdisk)

The following job is to format the hard disk. I want to format it to ext3.

Attach virtual hard disk

Well differentiated and formatted. The following is the Mount

I mount/dev/sdb1 to/share. If it is mounted to an existing folder,Note: Make sure to back up the original folder !!! And then copy it in...

[Root @ linux root] # mkdir/share # first create the mounted directory data1

[Root @ linux root] # Mount/dev/sdb1/share # Mount sdb1 to data1

After the system is restarted, check whether the mounting is successful:

[Root @ Linux data1] # DF-H

File System capacity used available % mount point

It indicates that the mounting is successful. You can view the mounted data1 under the root directory...

Done !!!
