+<WRAP Group> <WRAP column half> There are several actions which can be applied on a volume. You can see the list of them by clicking the small arrow on the very right of each volume row. The most useful ones are described as follow.
+The volume which is not attached and has no related snapshot can be deleted by **Delete Volume** .
+The size of the volume which is not attached can be increased by **Extend Volume** .
+The volume which is not attached can be transferred to another project by **Create Transfer** . The necessary quota in destination project should be met. The provided "Transfer ID" and "Authorization Key" should be given to receiver, to be used for accepting the transfer.

+<WRAP Group> <WRAP column half> To attach or detach a Volume to or from an instance, the **Manage Attachments** option should be used.
+To attach a volume to a running instance, the following steps should be fulfilled:
+  * Select "Manage Attachment" of a volume with "Available" status.
+  * On displayed form, select the intended instance from the "Attach to Instance" list.
+  * You can optionally change the device name.
+  * Click "Attach Volume".
+  * Connect to your instance and run "//sudo fdisk -l//" to verify if the volume is attached.
+  * If the volume is new (has not been attached to another instance before) you will see a message in the output of previous command indicating that the disk doesn't contain a valid partition table.
+  * To format your device, execute: "//sudo mkfs -t ext3  /dev/vdc//"  (/dev/vdc should be replaced by your device name if it is different)
+  * Create a directory for mounting the new storage volume: "//sudo mkdir /mnt/my-volume//".
+  * Mount the new volume: "//sudo mount /dev/vdc /mnt/data-store//"
