Wel but the client was doing it's own compressing. So when the gzipper failed, the whole backup failed. At only 33% finished. I just did a test amrestore (true, amrecover wouldn't touch it). Got about 1/3 the amount of data that ought to be on that disk. So I think it really did fail, but registered it as a successful level 0 backup. :-( > | DUMP: Broken pipe > | DUMP: The ENTIRE dump is aborted. > ? index returned 1 > ??error [/sbin/dump returned 3, compress got signal 11]? dumper: strange > [missing size line from sendbackup] > ? dumper: strange [missing end line from sendbackup] > \ > > > But it appears that she went ahead and stored the partial data on tape > anyway, and considered this a good level 0 backup.

Has anyone else noted this? There have been several reports showing failed pipes in the index stream for various reasons. I wonder if those also were reported as valid dumps. -- Jon H.

Now that you mention it, I have had this, a couple of times in the last week. Am still trying to debug it, but: sendbackup: start [hammer:/home level 0] sendbackup: info BACKUP=/bin/tar sendbackup: info RECOVER_CMD=/bin/gzip -dc |/bin/tar -f... - sendbackup: info COMPRESS_SUFFIX=.gz sendbackup: info end ? sendbackup: index tee cannot write [Broken pipe] ? index returned 1 ??error [/bin/tar got signal 13, compress got signal 11]? dumper: strange [missing size line from sendbackup] ? dumper: strange [missing end line from sendbackup] [...] hammer /home 0 0 1568 --0:08 184.4 0:04 442.5 The "listed incremental dir" shows: -rw---1 backup backup 0 Sep 23 23:20 hammer_home_0.new The filesystem in question is some 13Gb. Apparently the compress process is SEGVing, but I'm not seeing a core anywhere. Amanda version is 2.4.4-2 (Debian package), server and client are the same machine. Not seeing this on any other boxes, and I have another Debian box with a very similar configuration working fine. -- Phil Homewood, Systems Janitor, http://www.SnapGear.com [EMAIL PROTECTED] Ph: +61 7 3435 2810 Fx: +61 7 3891 3630 SnapGear - Custom Embedded Solutions and Security Appliances
Re: y didn't amanda report this as an error?
Hi Deb, Which release of amanda are you using? amanda-2.4.4p1 will report a failed dump for this kind error and reschedule a level 0 for the next day. That was fixed on 2003-04-26.

But this is not relazed to a gzip. The gzip for the index always runs on the server. Instead this sound like /tmp full, probably on the client. > > | DUMP: Broken pipe > > | DUMP: The ENTIRE dump is aborted. > > ? index returned 1 > > ??error [/sbin/dump returned 3, compress got signal 11]? dumper: strange > > [missing size line from sendbackup] > > ? dumper: strange [missing end line from sendbackup] > > \ And this is a result of the failed gzip; as already mentioned.
