The way I would approach this is with an automatic value. In eprint_fields_automatic, set a value in a new field.  That value would be multiple and would contain 'A-D' ('E-H', etc) for each author's family name.  You then have a multi-field browse view that goes to this new field first, then to author's family name.  You may also need to copy the family names with the letters in that range into another new field to support this.

See:

Hi Alan and Adam,

Thanks for your suggestions. We are running EPrints 3.3.11 and the free
space on our hard disk is not a problem. I checked with a colleague and
he confirmed my guess that the problem is caused by the number of files
in the directory, obviously the maximum number was reached last week and
no further files can be created.
Does anybody have a quick idea on how to divide files for one view, the
person view, to different directories? Would it be possible to define
different views for groups of letters, e.g. A-D or something like that?

Thanks!

What specific version of EPrints are you running?  What is line 1550 of /usr/share/eprints3/perl_lib/EPrints/Update/Views.pm

Also, silly question, but how much free space do you have on your hard disk?

Subject: [EP-tech] Problems with view generation: EPrints System Error

Hello,

since last week, we've had problems with the view generation for our
author/person view. These problems specifically concern the views for
new author names, which are not generated, while the views for already
existing author names are updated.

For each author name concerned, there is an entry in the apache error log:

Error writing to /usr/share/eprints3/archives/ubt_eref/html/de/view/person/Kaiser=3AMario=3A=3A.export: File too large
------------------------------------------------------------------
  at /usr/share/eprints3/perl_lib/EPrints/Update/Views.pm line 1550
         EPrints::Update::Views::output_files('EPrints::Repository=HASH(0x7fb0663688d0)', '/usr/share/eprints3/archives/ubt_eref/html/de/view/person/Kai...', 'XML::LibXML::DocumentFragment=SCALAR(0x7fb06a7e5938)', '/usr/share/eprints3/archives/ubt_eref/html/de/view/person/Kai...', 'XML::LibXML::Element=SCALAR(0x7fb06a45f160)', '/usr/share/eprints3/archives/ubt_eref/html/de/view/person/Kai...', 'XML::LibXML::DocumentFragment=SCALAR(0x7fb06a7e5938)', '/usr/share/eprints3/archives/ubt_eref/html/de/view/person/Kai...', 'XML::LibXML::DocumentFragment=SCALAR(0x7fb06a668aa8)', ...) called at /usr/share/eprints3/perl_lib/EPrints/Update/Views.pm line 935

         EPrints::Apache::Rewrite::handler('Apache2::RequestRec=SCALAR(0x7fb06a471710)') called at -e line 0
         eval {...} called at -e line 0

In this specific case, the author's name is linked to only 2 EPrints
entries, so it is unlikely that this file would be particularly large.

Does anybody have an idea concerning this? I would appreciate any help.

Thanks!

Verena
