After migrating to the RELENG_7 branch, I was never able to successfully build after any csup updates. I noticed that parts of edited files were 'missing'. No syslog messages were observed. After deleting the truncated file and running csup again, the buildworld was mostly successful. Occasionaly I would have another truncated file, requiring deletion and running csup again. I remembered someting about 'write cache enable' sysctl default getting changed at the start of the RELENG_5 branch. After turning off the write cache, I had no further problems with building world after a csup of the source tree. It has been 4 weeks without any issues. I do a weekly csup and buildworld. My hard disk is a IBM Deskstar Model IC35L040AVVA07. DMESG shows: ad0: 39266MB at ata0-master UDMA100 I have been using this drive for several years and don't remember seeing this truncation issue until I went to the RELENG_7 branch. It is strange that csup never detects that the file has been damaged in this way, requiring a download of the complete file from the CVS Server. The sysctl variable 'hw.ata.wc="0" in /boot/loader.conf cured my problem. >How-To-Repeat: Csup with the sysctl variable hw.ata.wc set to 1 >Fix: Csup with the sysctl variable hw.ata.wc set to 0 >Release-Note: >Audit-Trail: From: Remko Lodder To: Thomas Laus Cc: freebsd-gnats-submit@FreeBSD.org Subject: Re: i386/127095: Csup truncates files using RELENG_& Date: Thu, 04 Sep 2008 23:19:22 +0200 Thomas Laus wrote: Ofcourse you tested with various cvsup servers right? -- /"\ Best regards, | remko@FreeBSD.org \ / Remko Lodder | remko@EFnet X http://www.evilcoder.org/ | / \ ASCII Ribbon Campaign | Against HTML Mail and News Responsible-Changed-From-To: freebsd-i386->mux Responsible-Changed-By: remko Responsible-Changed-When: Fri Sep 5 13:23:16 UTC 2008 Responsible-Changed-Why: Reassign to maintainer.
