/CACHE:<size in kilobytes> Specifies the size of the JFS buffer cache in Kilobytes. By default, this size is set to 12.5 percent of real memory.

/AUTOCHECK:drive[drive...] Specifies a list of JFS file systems, identified by driver letter, to be included in automatic recovery by CHKDSK at the time of JFS initialization. If an asterisk (*) is specified instead of a drive letter list, all JFS file systems will be included in automatic recovery during JFS initialization. If any drive letter is preceded by an arithmetic plus sign (+), CHKDSK will perform a full integrity check on the drive even if journal log replay has restored the drive to an apparently consistent state. If the list of drive letters ends with plus-asterisk (+*), CHKDSK will perform a full integrity check on all JFS file systems not specified in the list even if journal log replay has restored them to an apparently consistent state.

/L:OFF Specifies the lazy write parameters in seconds. OFF forces all to be synchronous. (JFS ignores any characters between the L (or l) and the colon, so valid flags are /L: /LAZY: /LW: /lazywrite: etc.)

/L:<synctime,maxage,bufferidle> Synctime is the interval at which the sync thread runs, default is 64. Maxage is the longest time that a modified file is kept in cache, default is synctime*4. Bufferidle is the time indicating a "recent" change. Changes newer than this value are not written unless the last write was older than maxage, default is Min(1, synctime/8).

The cachejfs.exe command allows the lazywrite parameters to be changed immediately. The syntax is to the IFS line, except that the /L: prefix is optional. In addition, the cachejfs command can modify the minimum and maximum number of free cache buffers to be maintained. Calling cachejfs with no parameters reports the current settings.

CACHEJFS [[/LAZYWRITE:]{OFF|syncTime[,maxAge[,bufferIdle]]}] /MINFREE:minfree /MAXFREE:maxfree
