Revolving around the core of technology
Disk partitions on Windows are very easy to visualize since they are labeled as drives. If you get an error complaining you're running out of disk space on D: drive, you know exactly where to add more disk.
Even though the concept of disk partition exists on Linux, it is not very easy to visualize.
Complications arise from the fact that drive letters are missing in Linux.
For example, if you add a new disk to your Linux machine, it does not magically add an F: drive to
your machine. Instead, you have to mount this new disk to a regular folder, which could have
a path like
Assume you have three physical disks with the following mounting points
|Physical Disk||Size||Mounted Path||Description|
|Disk 1||50GB||/||This is called the root partition and is usually where your OS is installed on|
|Disk 2||1TB||/share/bigDisk2||Another physical disk attached to the machine|
|Disk 3||5TB||/share/bigDisk3||Perhaps a USB drive attached to the machine|
/tmp/var/folder. That is because this folder is stored on Disk1 and it does not have room to hold a 100GB file.
/share/sub-folder. Again, this location is on Disk1
/share/bigDisk2/sub-folder1/sub-folder2, because this location is on Disk2
/share/bigDisk2/sub-folder1, since Disk2 is only 1TB. This file must be created in
/share/bigDisk3/sub-folder1/, which is on Disk3
df -hFollowing is an example of sample result:
Filesystem Size Used Available Use% Mounted on none 250.0M 229.3M 20.7M 92% / devtmpfs 937.7M 8.0K 937.7M 0% /dev tmpfs 64.0M 1008.0K 63.0M 2% /tmp tmpfs 16.0M 0 16.0M 0% /mnt/snapshot/export /dev/md9 493.5M 133.7M 359.7M 27% /mnt/HDA_ROOT cgroup_root 945.8M 0 945.8M 0% /sys/fs/cgroup /dev/mapper/cdev1 4.5T 2.9T 1.5T 65% /share/CACHEDEV1_DATA /dev/md13 417.0M 375.9M 41.0M 90% /mnt/extIn the above example, there are 1.5TB available in
/share/CACHEDEV1_DATAfolder. Therefore, try using this location for all of your data files.
