Specifying the RAM disk size

The oneSIS RAM disk often only needs to contain links and several small files. Server logs and similar output can be configured to be sent to log servers or NFS-mounted directories to eliminate the need for persistent local storage.

The default maximum size of the oneSIS RAM disk is 1MB. A larger RAM disk can be created if desired. If any RAM* or LINK* directives are using the -d flag to duplicate files in /ram, a larger RAM disk may be necessary.

The RAM disk is first created by rc.preinit at boot time, but the update-node script can be used to re-size the RAM disk according to the current configuration after a node is booted.

RAMSIZE $<$max_size [k$\vert$m$\vert$g]$>$ [-c class[,class]...] [-n node[,node]...]
Directs oneSIS to create a RAM disk that can grow to at most max_size units. Units can be specified in kilobytes(k), megabytes(m), or gigabytes(g).
| Supplying any -c options limits the directive to apply only to the given classes.
| Supplying any -n options limits the directive to apply only to the given nodes.
