11 * Information Technology Center
15 * The Andrew File System startup process. It is responsible for
16 * reading and parsing the various configuration files, starting up
17 * the kernel processes required by AFS and feeding the configuration
18 * information to the kernel.
20 * Recognized flags are:
21 * -blocks The number of blocks available in the workstation cache.
22 * -files The target number of files in the workstation cache (Default:
24 * -rootvol The name of the root volume to use.
25 * -stat The number of stat cache entries.
26 * -hosts List of servers to check for volume location info FOR THE
28 * -memcache Use an in-memory cache rather than disk.
29 * -cachedir The base directory for the workstation cache.
30 * -mountdir The directory on which the AFS is to be mounted.
31 * -confdir The configuration directory .
32 * -nosettime Don't keep checking the time to avoid drift (default).
33 * -settime Keep checking the time to avoid drift.
34 * -rxmaxmtu Set the max mtu to help with VPN issues.
36 * -disable-dynamic-vcaches Disable the use of -stat value as the starting size of
37 * the size of the vcache/stat cache pool,
38 * but increase that pool dynamically as needed.
39 * -debug Print out additional debugging info.
40 * -kerndev [OBSOLETE] The kernel device for AFS.
41 * -dontfork [OBSOLETE] Don't fork off as a new process.
42 * -daemons The number of background daemons to start (Default: 2).
43 * -rmtsys Also fires up an afs remote sys call (e.g. pioctl, setpag)
45 * -chunksize [n] 2^n is the chunksize to be used. 0 is default.
46 * -dcache The number of data cache entries.
47 * -biods Number of bkg I/O daemons (AIX3.1 only)
48 * -prealloc Number of preallocated "small" memory blocks
49 * -pininodes Number of inodes which can be spared from inode[] for
50 * pointing at Vfiles. If this is set too high, you may have
51 * system problems, which can only be ameliorated by changing
52 * NINODE (or equivalent) and rebuilding the kernel.
53 * This option is now disabled.
54 * -logfile [OBSOLETE] Place where to put the logfile (default in
56 * -waitclose make close calls always synchronous (slows em down, tho)
57 * -files_per_subdir [n] number of files per cache subdir. (def=2048)
58 * -shutdown Shutdown afs daemons
