- | ### Resizing filesystems You may want to resize a UML filesystems because it isn't large enough. This is a common complaint with the filesystems available for download here since they tend to be just big enough to hold what's pre-installed in them, making it tough to install more stuff. Shut down the uml guest `UML# halt` Make a backup of the file you want to resize. If you have any COW files which have the file you want to resize as a backing file then make a backup of the cow files, too. If you want to merge the cow file with uml_moo, do it now. Otherwise remove the cow file to avoid confusion. Make sure the filesystem is in a clean state. `host% e2fsck -f filename` Resize the file. `
      host%
      dd if=/dev/zero of=filename bs=1 count=1 seek=newsize conv=notrunc

      0+0 Records in
      0+0 Records out
` newsize can be any size recognized by "dd", such as "256M", "4G", or "2T". The length of the file should have changed, but not the actual filesize as with "ls -ls". Resize the filesystem. `host% resize2fs -p filename` If you don't trust your luck and/or your computer run: `host% e2fsck -f filename` Start the uml with the new filesystem
