Operating Systems HP-UX About Block Size and Fragment Size Post 302929743 by Scrutinizer on Thursday 25th of December 2014 05:29:56 PM

That is the volume manager, but you probably mean VXFS? A fragment size equal to the block size makes sense for (cooked) database applications (especially if it is equal to the database block size) or for other applications where you mainly have large files. With lots of small files you are wasting space and a smaller fragment size would be more likely be the way to go.

Your root VG does not have a block size. Perhaps you mean that every VXFS filesystem in every LV in your root VG has a 8KB fragment size? That would not seem like a logical choice to me..

gd_fragmentname(3)						      GETDATA							gd_fragmentname(3)

NAME
gd_fragmentname -- retrieve a dirfile format specification fragment name SYNOPSIS
#include <getdata.h> const char* gd_fragmentname(const DIRFILE *dirfile, int index); DESCRIPTION
The gd_fragmentname() function queries a dirfile(5) database specified by dirfile and returns the filename of the format specification fragment indexed by the non-negative index. The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3). The fragment with index equal to zero is always the primary fragment for the database (the file called format in the root dirfile directo- ry). The largest valid value of index is one less than the total number of fragments, which may be obtained from a call to gd_nfrag- ments(3). RETURN VALUE
Upon successful completion, gd_fragmentname() returns a pointer to a read-only character string containing the file name of the specified fragment. On error, gd_fragmentname() returns NULL and sets the dirfile error a non-zero error value. Possible error values are: GD_E_BAD_DIRFILE The supplied dirfile was invalid. GD_E_BAD_INDEX The supplied index was out of range. The dirfile error may be retrieved by calling gd_error(3). A descriptive error string for the last error encountered can be obtained from a call to gd_error_string(3). SEE ALSO
dirfile(5), gd_error(3), gd_error_string(3), gd_include(3), gd_nfragments(3), gd_open(3), gd_parent_fragment(3) Version 0.7.0 21 July 2010 gd_fragmentname(3)
