Increasing total data size per file system request for block drivers
Hi All,
I am writing a block driver for a 2GB SD card where i get the total amount of data per request as follows:
Here, the total_bytes i.e the amount of data per request sent/received by file system is always <= 4KB.Hence it affects the card's read/write performance for large file size as the process needs to be repeated for every 4KB.
Is it like, the linux file system block size is limited to 4KB?
Is there any way to increase the transfer size per request?
How do i increase the filesystem size on a root partition?
There is a slice with root on it, its like 2 gigs and nothing else is broken out except home.
I want to increase root filesystem (and slice) and break out /usr and /var.
This is solaris 9, only has solaris volume manager on it.

FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
