Where is /dev/mapper?


Last night,I tried the Fedora Core 6 vmware image on my slackware box.Like most of you,I clicked on the update packages and then my / root nearly became full.As a result,I resize my vmware size to 10GB from 4GB.Out of my surprise,when I installed Oracle 10g express edition,it complained that there are not enough space left.So,I check with "df" command and my root is using 99% of space! I can see that the root is mounted to /dev/mapper/log**. something.I can't figure where it is so I can enlarge it to install Oracle.

Do you guys have any suggestions to this newbie?

That is similar to a loop device and is probably the special block file device for accessing your vmware file as if it were a filesystem. You could enter "mount" by itself to see which file is being mounted as the virtual root directory. The file itself will be listed in the second column. However, it is possible that the /dev/mapper/log.* device is used to control a portion of the file, such as if you had an image of a hard drive and mounted partitions of the image. The /dev/mapper/log.* device in that case will be for the filesystem mounted on a part of the file.
