NAME
diskarbitrationd — disk arbitration daemon
SYNOPSIS
diskarbitrationd [-d]
DESCRIPTION
diskarbitrationd listens for connections from clients, notifies clients
of the appearance of disks and filesystems, and governs the mounting of
filesystems and the claiming of disks amongst clients.
diskarbitrationd is accessed via the Disk Arbitration framework.
Options:
-d Report detailed information in /var/log/diskarbitrationd.log.
This option forces diskarbitrationd to run in the foreground.
The file /etc/fstab is consulted for user-defined mount points, indexed
by filesystem, in the mount point determination for a filesystem. Each
filesystem can be identified by its UUID or by its label, using the con-
structs “UUID” or “LABEL”, respectively. For example:
UUID=DF000C7E-AE0C-3B15-B730-DFD2EF15CB91 /export ufs ro
UUID=FAB060E9-79F7-33FF-BE85-E1D3ABD3EDEA none hfs rw,noauto
LABEL=The\040Volume\040Name\040Is\040This none msdos ro

NAME
dynamic_pager — dynamic pager external storage manager
SYNOPSIS
dynamic_pager [-E] [-F filename] [-S filesize] [-H high-water-trigger]
[-L low-water-trigger] [-P priority]
DESCRIPTION
The dynamic_pager daemon manages a pool of external swap files which the
kernel uses to support demand paging. This pool is expanded with new
swap files as load on the system increases, and contracted when the swap-
ping resources are no longer needed. The dynamic_pager daemon also pro-
vides a notification service for those applications which wish to receive
notices when the external paging pool expands or contracts.
OPTIONS
-E Encrypt the data in the swap files.
-F The base name of the filename to use for the external paging
files. By default this is /private/var/vm/swapfile.
-S The fixed filesize [in bytes] to use for the paging files. By
default dynamic_pager uses variable sized paging files, using
larger sized files as paging demands increase. The -S, -H and -L
options disable that default and cause dynamic_pager to use a
series of fixed sized external paging files.
-H If there are less than high-water-trigger bytes free in the
external paging files, the kernel will signal dynamic_pager to
add a new external paging file.
-L If there are more than low-water-trigger bytes free in the exter-
nal paging files, the kernel will coalese in-use pages and signal
dynamic_pager to discard an external paging file.
Low-water-trigger must be greater than high-water-trigger +
filesize.
-P This option is currently unimplemented.
FILES
/private/var/vm/swapfile* Default external paging files.
