cat: [file]: Invalid argument
Hola,
$ cat winxp1.8.ova > /dev/null cat: winxp1.8.ova: Invalid argument What could cause this? This 3GB file is not entirely readable anymore. When I cat/copy/md5/rsync it I always get errors. It happens to more big files, and to big files only. rsync says: rsync: read errors mapping "[snip]/winxp1.8.ova": Invalid argument (22) ERROR: [snip]/winxp1.8.ova failed verification -- update discarded. Dmesg doesn't say a thing. This same file is on multiple volumes, and all volumes give this fault. I just upgraded to OpenBSD Current (OpenBSD lilium.garden 5.0 GENERIC#90 i386) This is the first time I see this error, and I backup almost daily with rsnapshot/rsync. The filesystem is not corrupt. I don't think a file on itself can become corrupt so that cat(1) cannot read it anymore. Ow, and the ova file is still usable by VirtualBox :-) Could this be an OpenBSD bug? Update: I transferred the ova file to another computer via NFS. There, the ova file is usable. So, the file is actually readable. Maybe NFS is not very picky about errors?

Maybe ova file was not a good example. Another example as root: # dd if=winxp1.8.ova of=/dev/null dd: winxp1.8.ova: Invalid argument 4194303+0 records in 4194303+0 records out 2147483136 bytes transferred in 116.564 secs (18423057 bytes/sec) Diagnostic tips (hints) are also welcome. Update: Ok, bit dumb to use an ova-file example again. But other files had the same problem anyway. Last edited by pieterverberne; 17th November 2011 at 09:29 PM. |

Looks like it is fixed by downgrading to OpenBSD 5.0 stable release.

http://www.openbsd.org/report.html Taking the time to provide a thorough, detailed, & complete report will help the developers resolve the issue faster. Providing complete outputs of dmesg(8) for both configurations will certainly help. |

Sorry (to the OpenBSD developers), but I'm not really planning to upgrade, make a bug report and downgrade again. I did sent a mail to bugs@openbsd.org but never find a copy on http://marc.info/?l=openbsd-bugs&r=1&b=201111&w=2 . (I thought bugs@openbsd.org was a public list?)

Your report was published to bugs@. Unfortunately, marc.info has had problems with regular updates since September, sometimes going many days, or even weeks, without recording incoming Email. Use Gmane.
