TO MODIFY THE JFS LAZYWRITE PARAMETERS ON THE IFS= LINE IN CONFIG.SYS:

IFS=jfs.ifs /L:OFF IFS=jfs.ifs /L:synctime,maxage,bufferidle

(JFS ignores any characters between the L (or l) and the colon, so valid flags are /L: /LAZY: /LW: /lazywrite: etc.)

OFF forces asynchonous writes to be immediately initiated.

synctime is the interval at which the sync thread runs. Default = 64

maxage is the longest time that a frequently modified file is kept in cache. default = 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 = MIN(1,synctime/8)

(All parameters in seconds)

IFS=C:\OS2\JFS.IFS /L:64

synctime = 32, maxage = 128, bufferidle = 4

IFS=C:\OS2\JFS.IFS /LW:10,60,5

synctime = 10, maxage = 60, bufferidle = 5

IFS=C:\OS2\JFS.IFS /LAZYWRITE:4,60

synctime = 4, maxage = 60, bufferidle = 1

IFS=C:\OS2\JFS.IFS /lazy:off

All writes initiated immediately (synctime=1, maxage=bufferidle=0)
Note: sync thread still runs since trivial things like marking an inode accessed are still deferred.
