I tried to get some hints from amanda by digging through the source
code.
I found out, that the disklist itself is read in correctly (all entries
are present in the program's C structure). Looking a little bit further
revealed the problem: The amanda server issues the sendsize command to
the clients (asking for sizes for level0 and level1 dumps in this case).
This question is passed on via some protocol to the client (in this case
adler). On the client side in sendsize program there is a loop reading
in
from (stdin), the daemon somehow I assume. The last line I get here
while
reading is truncated (even in case I back up 32 filesystems here; the
exclude=file information is truncated which I can also see in the
logfile
later). The command for getting required sizes simply is too long!

This also fits well with the error I get: adler does not compute the
dump sizes for those filesystems it does not see. And amanda server is
wondering why there are no answers for these filesystems -> "missing
result".

I saw that this is a known problem when searching through the
amanda-hackers
archive at egroups. There should be a patch available; in fact John
already supplied me with this patch and I tried it, but it did not work.
Maybe I got a broken version of the patch?? John, could be please check
this again?

Kind regards,
Urte

increasing maxdumps did not help. Again I got

Hi Chris,

> What do you have maxduumps set to?  Maybe increasing or decreasing it
> for this one host will help.
Maxdumps is set to the default value ( = 1). man page says:

  maxdumps int
   Default:  1.  The maximum number of backups from a
   single host that Amanda will attempt to run in
   parallel.  See also the inparallel option.

   Note that this parameter may also be set in a specific
   dumptype (see below).  This value sets the default for
   all dumptypes so must appear in amanda.conf before any
   dumptypes are defined.
This does not seems to be a solution for my problem. But nevertheless,
I can try if it has any effect. I'll set maxdumps to 2 and see what
happens this night.

Hi Chris,

I also have more than 32 filesystems altogether, but I have more than 32
filesystems for one single host. That's where the problem occurs. Do you
have this case as well without any failures?

> You've tried rearranging the order of disklist entries to see if there's
> a problem there?
I did not try rearrangement, but I commented out the directories which
are not so important at the moment (so that I'm backing up exactly 32
filesystems for this host), and then the missing filesystems root and
home ware backed up successfully without any problems. So this does not
look like a problem on the filesystems itself.

> If you're using dump for the backups can your dump handle directories?

I use tar so this should not be ok.

Dont know if you know about the problem. I once again include my
original email here to get you up to date:

-- original email --
Hello list,

I have a problem with amanda 2.4.2p2.

I'm doing backups on three SUN machines with amanda for quite some time
wihout any major problems.

About 2 weeks ago  we removed the bunch of single external disks from
that host and added one big raid disk (which is of course too big to be
backed up entirely on our 20gb native capacity tape). I then changed the
disklist for this host from about 7 filesystems (= physical disk
partitions) to 38 directory starting points.

The first few days of course we had missing filesystems on tape until
amanda has been able to do a level 0 dump on each of the new entries.
Nevertheless 6 of the entries remain non-backuped (including the root
filesystem and the user filesystem :-( ). I assume it might be a problem
with the number of entries in the disklist (I saw some discussions about
this in this newsgroup, but that turned out to be an error in the
exclude statement). I noticed that these 6 entries are the ones which
stand on top of the list.

The error in the mail report says:

FAILURE AND STRANGE DUMP SUMMARY:
  adler  /usr/export/amis/raid2/disk_head_97_05 lev 0 FAILED

I dont see something unusual in the /tmp/amanda/-files. Just ask if you
would like to see some extracts from there.

John then sent me some patch, but he was not sure wheather this would
help. And it did not. Thats the current state of the art.

Re: amdump problem: "missing result" reported

[Urte Fuerst]

Hi John,

> I'm not sure if this will fix your problem, but it is the patch that
> allows requests larger than a single packet.
Unfortunately this patch did not fix it. I added the patch to the source
code, recompiled and reinstalled amanda. Then I added 2 of the 6
filesystems in the disklist again which I had commented out two weeks
ago.

Now I get the same error again in the amanda report:

FAILURE AND STRANGE DUMP SUMMARY:
  adler  /usr/export/home/adler lev 0 FAILED [missing result for
/usr/export/home/adler in adler response]
  adler  / lev 0 FAILED [missing result for / in adler response]

These two are again the first two filesystems in the disklist for host
adler which are missing on tape.

For me it really looks like a max-32-fileystems-per-host limit.

What has changed now with the patch is the /tmp/amanda/sendsize.debug
output. I'm sure I found the / and home  stuff in sendsize.debug before
(even when they were not backed up), but now they are no longer present. 

??
Kind regards, Urte

P.S. I'll try to CC: the amanda list. Maybe I can get through somehow?

Hello list,

unfortunately I did not receive any answer concerning my problem with

I ran across the same problem yesterday when trying to restore a
directory which had been deleted by accident. I should have seen more
than 15 directories with "ls" in amrecover, but all I got was 3
entries. I tried the "setdate" command, but that did not help. In the
index-files all the directory entries where present, and I was able to
restore the directory "by hand". This happens in my case with amanda
2.4.1p1 on Solaris 2.6 system.

Has anybody an idea what is happening here?

Yes, that solved my problem. /win is now backup up as desired. Thanks

backup on linux/win98 client

[Urte . Fuerst]

Hi,

I have a new laptop with dual boot (Win98 and SuSE Linux 7.0). I'm
trying to backup this client with amanda version 2.4.1p1. The linux
side
itself is working excellent; but I would also like to backup the /win
partition where the windows file system is mounted. I get the
following
message in sendsize.debug:

...

Looks like the vfat filesystem is not recognized by amanda. Is there a
way to get this working?

Thanks for any responses,
Urte
