Hi, This post is about the "ERROR: attempting to write beyond end of file" error message described in threads [1] and [2]. ( I wasn't subscribed to the list at the time ).
For the record, I just want to present a way to reproduce this if needed in future and confirm that r2192 indeed fixed it. On Jun 28, Tobi wrote in [2] that: > only in the sense that I was not able to reproduce this on our > systems ... it would be great to figure the cause of this ... One way to reproduce this is: * Install a minimal debian squeeze system from scratch. E.g. use the iso [3]. * apt-get install rrdtool * run the attached reproduce.sh * See the attached reproduce.out.txt Basically: rrdtool create created.rrd DS:var1:GAUGE:600:U:U RRA:AVERAGE:0.5:1:25 rrdtool resize created.rrd 0 GROW 1 fails, but putting created.rrd through a dump/restore cycle makes it work. The next day, Jun 29, Tobi commited: r2192 | oetiker | 2011-06-29 17:18:22 +0200 (Wed, 29 Jun 2011) | 2 lines Changed paths: M /branches/1.4/program/src/rrd_format.c M /branches/1.4/program/src/rrd_resize.c M /trunk/program/src/rrd_format.c M /trunk/program/src/rrd_resize.c I can confirm that /branches/1.4/ part of the fix works when applied to rrdtool 1.4.3 on debian squeeze and that a raw checkout of svn://svn.oetiker.ch/rrdtool/trunk/program also works.
