11 | .SH DESCRIPTION | |
12 | .I Swapon | |
13 | is used to specify additional devices on which paging and swapping | |
14 | are to take place. | |
15 | The system begins by swapping and paging on only a single device | |
16 | so that only one disk is required at bootstrap time. | |
17 | Calls to | |
18 | .I swapon | |
19 | normally occur in the system multi-user initialization file | |
20 | .I /etc/rc | |
21 | making all swap devices available, so that the paging and swapping | |
22 | activity is interleaved across several devices. | |
23 | .PP | |
24 | Normally, the | |
25 | .B \-a | |
26 | argument is given, causing all devices marked as ``sw'' | |
27 | swap devices in | |
28 | .B /etc/fstab | |
29 | to be made available. | |
30 | .PP | |
31 | The second form gives individual block devices as given | |
32 | in the system swap configuration table. The call makes only this space | |
33 | available to the system for swap allocation. | |

39 | .SH BUGS | |
40 | There is no way to stop paging and swapping on a device. | |
41 | It is therefore not possible to make use of devices which may be | |
42 | dismounted during system operation. |
