disable-fzbm
Create the filesystem without Full Zone Bit Maps (FZBMs). The FZBM on-disk
filesystem format reduces the amount of data that the filesystem needs to read
when allocating a block. It is particularly useful for speeding up allocation times
on large, relatively full filesystems.
enable-quotas
Enables quotas on the filesystem.
userdefault=<size>, groupdefault=<size>
Set the default quota limit for users or groups, respectively, to size bytes. (The
defaults are rounded down to the nearest filesystem block.) The <size> argument
can include one of these optional modifiers to specify the unit: K (kilobytes), M
(megabytes), G (gigabytes), or T (terabytes). If one of these modifiers is not spe-
cified, the <size> will be interpreted in bytes. If the default quota limit is not
specified on the command line, the limit will be set to 0, which means there is
no default limit.
The userdefault and groupdefault parameters are invalid if the enable-
quotas parameter is not also specified.
The following command shows the syntax for the quotas parameters:
mkpsfs -o enable-quotas,userdefault=#[T|G|M|K],
groupdefault=#[T|G|M|K] dev
If no -o options are specified, the filesystem will be created with Full Zone Bit Maps
(FZBM) and without quotas support.
