A: The free program, Amanda, receives a lot of mentions on Usenet. Its home page is http://www.amanda.org.
A: Several commercial backup utilities also exist. They are often included in commercial distributions.
A: To format a 3.5-inch, high density floppy at the command prompt:
$ fdformat /dev/fd0H1440 $ mkfs -t ext2 -m 0 /dev/fd0H1440 1440 |
Device naming conventions generally are the same as for other unices. They can be found in Matt Welsh's Installation and Getting Started guide. Refer to (``Where Is the Documentation?'') A more detailed and technical description is Linux Allocated Devices by H. Peter Anvin, hpa@zytor.com, which is included in LaTeX and ASCII form in the kernel source distribution (probably in [/usr/src/kernel/Documentation/]), as [devices.tex] and [devices.txt].
A: When you boot (or enable swapping manually) you should see
Adding Swap: NNNNk swap-space |
If you don't see any messages at all you are probably missing
swapon -av |
startup scripts), or have forgotten to make the right entry in [/etc/fstab]:
/dev/hda2 none swap sw |
Unable to find swap-space signature |
you have forgotten to run mkswap. See the manual page for details; it works much like mkfs.
Running the command free, in addition to showing free memory, should display:
total used free Swap: 10188 2960 7228 |
# dd if=/dev/zero of=/swap bs=1024 count=65535 # mkswap /swap # swapon /swap |
When you don't need the swap space any more, remove it with the following statements:
# swapoff /swap # rm /swap |
If that still doesn't provide enough swap space, refer to (``How To Have More Than 128Mb of Swap'')
A: To understand how you got into this state, see, (``EXT2-fs: warning: mounting unchecked file system'')
Remount it. If [/etc/fstab] is correct, you can simply type:
mount -n -o remount / |
If [/etc/fstab] is wrong, you must give the device name and possibly the type, too: e.g.
mount -n -o remount -t ext2 /dev/hda2 / |
A: JFS is still under development.
