.SH OPTIONS
|

|
|
.TP
|
||
|
|
.BI \-a " heap-based-allocation"
|
||
|
|
Specify 1 or 0 to enable/disable heap based block allocation policy.
|
||
|
|
If the value is equal to 1, each of active log areas are initially
|
||
|
|
assigned separately according to the whole volume size.
|
||
|
|
The default value is 1.
|
||
|
|
.TP
|
||
|
|
.BI \-l " volume-label"
|
||
|
|
Specify the volume label to the partition mounted as F2FS.
|
||
|
|
.TP
|
||
|
|
.BI \-o " overprovision-ratio-percentage"
|
||
|
|
Specify the percentage over the volume size for overprovision area. This area
|
||
|
|
is hidden to users, and utilized by F2FS cleaner. The default percentage is 5%.
|
||
|
|
.TP
|
||
|
|
.BI \-s " log-based-#-of-segments-per-section"
|
||
|
|
Specify the log-based number of segments per section. A section consists of
|
||
|
|
multiple consecutive segments, and is the unit of garbage collection.
|
||
|
|
The default number is 0, which means one segment is assigned to a section.
|
||
|
|
.TP
|
||
|
|
.BI \-z " #-of-sections-per-zone"
|
||
|
|
Specify the number of sections per zone. A zone consists of multiple sections.
|
||
|
|
F2FS allocates segments for active logs with separated zones as much as possible.
|
||
|
|
The default number is 1, which means a zone consists of one section.
