amanda is stuck in the middle of backup
I have a strange problem with amanda my server is a Redhat linux 7.3 machine with amanda 2.4.3b3 my client is a redhat7.3 machine with a stock amanda package from redhat version 2.4.2p2 In my report for this client some backup work and some don't I got the message could not connect to molure for some of the partition. Indeed when i ran amcheck this machine coul'nt be check and i got the same message. When i log on this machine all is running except the fact than xinetd didn't spawn the amandad process. when i do a ps i found an amandad process 15933 ?Z 0:00 [amandad ] this process is a son of the xinetd process but when i look at amandad file related to this process all seems ok Here is the end of this file got packet: Amanda 2.4 REQ HANDLE 000-F8B70708 SEQ 1031857221 SECURITY USER dumpy SERVICE sendbackup OPTIONS hostname=molure; GNUTAR /var/spool/imap13 0 1970:1:1:0:0:0 OPTIONS |;bsd-auth;compress-fast;index;exclude-list=/usr/local/lib/amanda/exclude.gtar; sending ack: Amanda 2.4 ACK HANDLE 000-F8B70708 SEQ 1031857221 bsd security: remote host backup.int-evry.fr user dumpy local user amanda amandahosts security check passed amandad: running service "/usr/lib/amanda/sendbackup" amandad: sending REP packet: Amanda 2.4 REP HANDLE 000-F8B70708 SEQ 1031857221 CONNECT DATA 57421 MESG 57422 INDEX 57423 OPTIONS ;compress-fast;bsd-auth;index; amandad: got packet: Amanda 2.4 ACK HANDLE 000-F8B70708 SEQ 1031857221 amandad: pid 15933 finish time Thu Sep 12 22:17:32 2002 But the prcess stuck seems to prevent the launch of the following backup of different partition on the same machine? if i restart xinetd all run fine again but at the next backup i got again this problem.

Re: Tapetype
Not so sure about this. I had a Travan-4 tape whizzing away for 24 hours. Now, I've had full tapes before, and the dump time... lemme pull out the reports: Output Size (meg)3863.3 3829.7 33.6 ... Tape Time (hrs:min)2:15 2:05 0:10 Tape Size (meg) 3864.1 3830.0 34.1 Tape Used (%) 101.7 100.80.9 (level:#disks ...) So for a tapetype run it should take 4h30... Give it 5 hours.

Re: amverify only on most recent set
Hi Andrew,
I include a patch to amverify that add a third argument, the number of tape
you want to verify, it will take runtapes if the argument is absent.
I also include a new program (amverifyrun) which verify the tape
written in the latest run (amdump or amflush), this script grep
the log file to find the first slot to verify and the number of
tape use, it then call amverify with the appropriate parameters.
The third attachment is a patch for configure and Makefile to compile
and install amverifyrun.
I only did a few test, I'm using runtapes=1. Could you test it and
tell me if it works in your configuration.

1) IP Aliases; 2) Dump Order
Greetings. Amanda has been running great at our site, backing up 28 file systems for 6 hosts for the past year and a half. However, there are 2 questions I have about amanda. 1) We run Veritas Cluster Server, which has the ability to move a file system along with its associated IP address. When we first tried to use amanda, amcheck reported errors eprod and prod1 were both names pointing to the same "eprod" host - and you are not allowed to run amandad twice. Our kluge at that time was to write a translation script that would take a disklist and run hostname on each of the hosts in disklist, and write a new disklist with actual hostnames. This makes the assumption that a failover won't happen during the backup. The better thing would be to allow amanda to back up prod1:/dg/prod1 even though the real hostname of prod1 is "eprod". I am curious if anyone has encountered this, looked into it? 2) During Disaster Recovery Exercise, it would be really great to use amrecover to read the tape. But of course, a DR exercise assumes that the backup host is gone. I found the script showing how to list tape contents with "dd if=/dev/rmt/0n bs=32k count=1 | head -1", (Until I discovered the dd trick, I was afraid my nightly amverify would have to be printed and accompany the tapefortunately not) If I could just restore my index/tape host first, it would be better. The problem is, the order of the dumps is not constant. Is there a way to force it to put the index host on the tape first? Thanks Seth

Your label string says each tape must be labeled with a unique
string after the "word" DailySet1 consisting of a dash and "3" digits.

Note that this error is being brought to you by the chg-zd-mtx command.
Almost always, the chg-* scripts will need some tuning for the local
environment. One mtx version does not print the same string, for the
same type of drive, as the next.
For debugging you can (as amanda-user) cd to the config dir (?daily?).
The run chg-zd-mtx directly to manipulate the changer.

The above is normal output just so you know that tapetype hasn't

Looks good if its supposed to be a 10 gig tape. If not, then check
to see if the hardware compression is on, which for amanda is a
no-no. See my other recent messages about getting it turned off
and kept off.

"DailySet1" is the group name thats the default in amanda.conf, and
you need to also supply a trailing 1 or 2 digit number to complete
the unique label for each tape, like -1, -2, ... -20.

It means you got VERY different results than 2 others who put
their results into the Faq-O-Matic.
You got twice the capacity, half the speed, and a substantial
waste of space between files compared to their results.

1) is it reproducible?
2) are you certain compression was turned off?
3) do the numbers (capacity, speed) seem reasonable?
4) can you explain the difference between your results
and the previously listed ones? (tape size, eg longer,
technology, eg. xyz-2 vs xyz-1, slow, narrow scsi)

I don't know what release of amanda the tapetype came from. Old versions were horribly slow on some tape drives as it wrote an end of file mark after every 32K of random data. This resulted in what was known as "shoe shining" where after writing the filemark, the tape stopped, backed up to resync with the start of the next file, and resumed writing. For each 32K block!! You can probably check the specs for your tape drive. and determine approximately how long it should take to run. Two complete tape writes are done. If it takes longer than say 3 or 4 times the time needed for one complete write, something may be amiss. Tapetype is a standalone program. You could get the source from a new distribution and compile it. OH wait, nevermind -- I seem to be saying that frequently! :(( You gave tapetype an estimate. The -e option came in after the bad old days. -- Jon H. LaBadie [EMAIL PROTECTED] JG Computing 4455 Province Line Road(609) 252-0159 Princeton, NJ 08540-4322 (609) 683-7220 (fax)

You extract the tarball archive on your backup server and upload it to the Windows box, and there you untar it with the WinTar provided with Win32 Amanda (different of course from the GNU tar, due to NT file rights...). amrestore is possible, but I don't like the ability of the client to log in as root without password on the backup server, so I tested the solution but did not put it in production. amrestore is also helped by a GUI written in Python (need to install a Python interpreter on your Windows box, easy way but not so easy to automatically deploy). > > Have you, or will you, put the changes out for others?

RE: Working with multiple tape drives----- Ammended
Tien, if recalibration is what I need then, looking at my manual, it'd seem that this might be what I wanna do: Uncal Drive Target Allows the operator to uncalibrate a drive target. The next time a tape mount operation is called for that drive, the library recalibrates the target automatically as, for example, when a drive has been physically removed and replaced while the library is operating (hot swapped-only for qualified service personnel). Do you agree? -Original Message- From: Tien That Ton [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 12, 2002 3:35 AM To: [EMAIL PROTECTED] Subject: Re: Working with multiple tape drives- Ammended Reply With History On the library, sometimes due to transportation (and the library was not "Park" properly), the robot arm tends to miscalculate its "Y" position. That is when you need to re-calibrate. By re-calibrate I meant accessing the menu on the library and manually calibrate. On the units that we (Tandberg Data) sell, there is a special menu where you can select to manually calibrate the robot arm. This menu is NOT for normal user use, therefore its need a combinations of keys presses to make it appeared. What I would suggest for you to do is to get the manual for the library you have, maybe there is a section in there that tell you how to recalibrate. If not then you need to contact the support section. Regards Tien
HELP : amlabel - no tape online
Hi,
I am a newbie to Amanda. I have set up version
2.4.2.p2 on a RedHat
Linux 7.3 system with a HP SureStore 24x6 external
drive (HP C1557A).
Installation of amanda went on fine. Here are relevant
portions from
the amanda.conf file :
**
*
runtapes 1 # number of tapes to be used in a single
run of amdump
tpchanger "/etc/amanda/daily/chg-zd-mtx"# the
tape-changer glue
script
tapedev "/dev/nst0" # the no-rewind tape device to be
used
rawtapedev "/dev/nst0" # the raw device to be used
(ftape only)
changerfile "/etc/amanda/mtx-changer"
changerdev "/dev/sg0"
tapetype HP1557A# what kind of tape it is (see
tapetypes below)

}
**
I have tried using the mtx-changer command, and can
eject and load
individual tapes using it. However, when after all
configuration was
done, and I wanted to label a tape using the command:
su amanda -c "amlabel daily DailySet1"
I get this error:
*

I used info from this URL for tape changer

And for other Amanda installation and general
configuration, I
followed the guide at:
http://www.frankenlinux.com/guides/amandaserver.html
I have also tested my tape drive using tar commands,
and it works well
with the device file /dev/nst0. The changer device
file shows up as
/dev/sg1.
Here is the output of the mt status command:

While you can use mt to turn it off, on most drives is a switch that
will turn it off, a bit more dependable than remembering to do it
with mt, if your platforms mt even has that ability.
Which brings me to the next subject regarding compression.
Most modern drives can autoswitch, and will switch it back on if it
finds, in the tapes own, you can't read it, header, that the
compression is on for that individual tape. So basicly it doesn't
do you any good to turn it off if the *(&% tape itself turns it
back on during the tape recognition as each tape is inserted into
the drive.
What I've found to be a way to fix that is to rewind the tape, then
dd the amanda label block out to a scratch file, then rewind the
tape again, use mt to shut the compression off and write 20 megs or
so of data from /dev/zero to it using dd. Rewind it and rewrite
the scratch file back to restore the label.
By doing this long garbage data write, you are going to force the
drive to flush its buffers. When this is done, the drive will
re-write those hidden headers, doing it with the compression flag
now set to off. If such a flush operation is not forced, the drive
doesn't update those headers and you're stuck with xx gig tapes
that only hold less because the compression is on regardless of
your wishes. Sometimes much less when you feed the drives rll
compressor with a few gigs worth of bz2 files.

Re: SOLVED: amlabel: Operation not permitted
Hi, sorry to correct you, but you must not use /dev/st0 with amanda, the correct device for amanda is /dev/nst0, as this device does not rewind when it is closen. /dev/st0 rewinds the tape at close which is a nono with amanda. vxa tools are reporting a correct device for your tape, but not for the use with amanda. the /dev/sg[0-9] devices are for generic acces to scsi-devices, they offer another interface. If you want to operate a changer for example you'll have to use the sg-device. Christoph Caitlyn M.

HOWTO-here it is !!!!
Hi all
Please note this is just "phase 1" basis for discussion ;-)
It should cover all setups to be done on the server prior to the final
amanda setup.
So hopefully ;-) If you have done this you can just edit your amnda
config files and off you go !!!
Please look @ the following.
Is evereything in logical order? (I wrote as I went along)
Have I left enything out?
Have you got something to add ?
All contributions are welcome
Tnx
Mozzi
building and installing amanda for network backups
---
Please remember this is a newbie "quick&dirty" setup HOWTO
a)Thanx
Firstly thanx to the amanda users mailing listand evereybody there who
answered my questions so
patiently,without you guys I wouldn't have been able to do this.
b)Disclaimer
This worked for me.If you machie starts smoking or bursts into
flames,sorry I cannot do anything about it.
Should this happen please post to the list as I am sure evereyone would
like to hear about it,include a full
bugreport please ;-)
c)Setup
I use the following here
user=amanda
group=backup
profile=test
index machine=tapehost
I use Red-Hat 7.3 on x86
I have:
two ide harddrives
scsi Tandberg VS80 DLT tapedrive (internal)
Subsystem: Adaptec 29160 Ultra160 SCSI Controller
Make sure your kernel supports your scsi cotroller,how to setup that
is way beyond the scope of this document.
Use the link below to test your tapedrive.It is for DLT scsi.
If you use auto changers or robotics Sorry I do not have one to test
on ;-)
When you can use the mt utility on the tapedrive you are ready for
primetime!!!
To setup the DLT Tapedrive I found this link verey handy
http://www.quantum.com/NR/rdonlyres/6ayrpuorsal7nrdypfpq456w2ehie6zr7zubapbcq5marehyanix5v7xoovfrhjmtteqpm73zygud
/dlt8000linux.pdf
---
d)On index machine (where tape device is)
adduser amanda
groupadd backup
./configure --with-user=amanda --with-group=backup
make
make install
@ this point I like to switch off hardware compression
#mt -t /dev/nst0 -compression 0
I actually put that into my rc.local file to make sure.
As someone mentioned on the list amanda measures the output after
compression so you should score a lot
by doing this
Put the Amanda services into your /etc/services file on the tapehost
Add entries like so:
amanda 10080/udp
amandaidx 10082/tcp
amidxtape 10083/tcp
I just added them right @ the top
Add the following to your xinetd.d directory
vi amanda
cut&paste the following
service amanda
{
disable = no
socket_type = dgram
protocol= udp
wait= yes
user= amanda
group = backup
groups = yes
server = /usr/local/libexec/amandad
}
--
vi amandaidx
cut&paste the following
---
service amandaidx
{
disable = no
socket_type = stream
protocol= tcp
wait= no
user= amanda
group = backup
groups = yes
server = /usr/local/libexec/amindexd
}
-
vi amidxtape
cut&paste the following
--
service amidxtape
{
disable = no
socket_type = stream
protocol= tcp
wait= no
user= amanda
group = backup
groups = yes
server = /usr/local/libexec/amidxtaped
}
-
now we must get our config directory ready
mkdir /usr/local/etc/amanda/test
In the above test is the name of my profile stick to it for now but when
you setup your own
you can use whatever you want.
Now we copy the files we need into the config directory
cd ~/amanda-2.4.2p2/example/
cp amanda.conf config.site disklist
Make amanda the owner
chown amanda:backup /usr/local/etc/amanda/test
Now create the log directory
mkdir /usr/local/var/amanda
mkdir /usr/local/var/amanda/test
mkdir /usr/local/var/amanda/test/curinfo
mkdir /usr/local/var/amanda/test/index
mkdir /usr/local/var/amanda/test/tapelist
Make amanda the owner
chown -R amanda:backup /usr/local/var/amanda/test/
We will later edit the amanda.conf file to reflect this.
Now let's setup our holding area for images while they are waiting to be
written to tape
mkdir /var/dump
Make amanda the owner
chown -R amanda:backup /var/dump
We will later edit the amanda.conf file to reflect
Tapetype
Hi Watch out for tapetype!!! I have a Tandberg VS80 DLT 40/80 Gig drive I gave it the command #./tapetype -e 40960 -f /dev/nst0 -t TandbergVS80 It has been going for 26 hours now,and no end in sight. Mozzi

That looks as if you have the drives hardware compression enabled,
which for amanda is a Bad Thing(tm).
When you run tapetype, the source of the data is /dev/urandom. This
is not generally compressable data because there is little
removable redundancy in such data. And in most cases, the rll
encoder in the drive will actually expand such data, hence the
apparent short tape.
This also places an unknown into amanda's idea of what the tape will
hold as amanda counts bytes sent to the tape *after* any software
compression has been applied.
So turn off the hardware compression and leave it off forever. Then
re-run the tapetype.
Software compression is usually much more effective anyway. Last
nights run here put 8370k of real data out to the tape as 3780k on
a DDS2 120 meter tape, the first time I've actually had a tape 100%
used. And its a 46 gig system.

I'm gonna go out on a limb and say you have hardware compression turned
on...as any search through the archives will state, "turn if off and
leave it off". Software compression will most likely give you more than
the tape advertises (just ask Gene). If you are running linux, run "mt
-f /dev/tapedevice compression 0" . If you still get the same result
you may have to play with data density settings for the drive which will
require perusing the manuals.

Hi, everyone, I changed the device to /dev/st0 and everything worked, including amlabel. Apparently the problem is with vxaTool reporting the wrong device and not amanda. I'll report the bug to Exabyte. Thanks

This is true but as a friend pointed out to me recently when I was having some tape reading problems - if you get some bit errors reading a tar file from a tape, most likely asll you will lose is the affected file. If OTOH you get bit errors reading a gzipped tar file, you most likely will not be able to read anything after the bit errors. Just something to be aware of. Kindest regards, Niall O Broin

You probably have compression enabled on your drive, and
it is making tapetype's data bigger. Try turning off the
compression and re-running tapetype.

They work fine with ata100 stuff though as we're doing that with video drives for program delay and transport now. But thats temporary since the mpeg-2 standard doesn't do closed captioning which gets us phone calls from the hard of hearing folks. We only do that when the real dvc-pro machine is down for service, its our "program" backup. Now if we could figure out how to automate the removal and replacement of several hundred surface mounted electrolytic capacitors when one of them starts pixelizing. Its hell on one's back, sitting at the bench working under a magnifying lamp doing that, takes 3 or 4 days to go all the way thru one of those $3k-$7k+ machines. Thats the major failure mechanism for a dvc-pro tape machine. :-( -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.15% setiathome rank, not too shabby for a WV hillbilly

Nope, they are not correct. The reason is that you probably have hardware
compression on which actually expands the data Amanda uses to determine
tapesize which in turn gives a smaller length.
However, you are in good company since, even though I have only been on
this list for a short time, this seems to be one of the most frequent
questions here.
I had the same problem and I solved it by removing the drive from it's
drivebox and changing a dip-switch. Some OS:s seems to allows you to
change if the drive should use compression with the mt command (I have not
found it in Solaris 8 though).
Also, tar+gnuzip gives you alot better compression than the internal
hardware of the drive, at least from what I've read on this list.
> Could someone give me more accurate values for this
> tape or point me to doc ?
I use the following tapetype:
define tapetype HP-C1554a {
comment "just produced by tapetype program"
length 10075 mbytes
filemark 0 kbytes
speed 872 kps
}
Perhaps the length could be a bit larger, but better safe than sorry. If
you change the drive to default to hardware compression off you can rerun
tapetype to get more accurate values.
Hope it helps!

Tape DDS-3 values
Hello,
I am using HP DDS-3 tapes for my backup. I've tried to
get the correct values for my tape. But tapetype gives
this result:
define tapetype HP-DDS3-DAT {
comment "just produced by tapetype program"
length 9860 mbytes
filemark 0 kbytes
speed 840 kps
}
I think this is not correct because I've a DDS-3 125M
tape with 12GB.
Could someone give me more accurate values for this
tape or point me to doc ?
Thanks in advance.

raw device permissions
Hi This is my stupid question of the week ;-) Sorry but my brain has deflated. Please bear with me for when my newbie howto is finished I hope it will stop questions like this. This is a direct quote from the INSTALL file B. Set up your raw disk devices so that the dumpuser can read them, and /etc/dumpdates so that the dumpuser can write to it. Normally this is done by making the disk devices readable by (and dumpdates read/writable by) group `operator', and putting the dumpuser into that group. Now my problem: Getting dumpuser to read the raw devices. I see in Red-Hat the default group is disk [root@backupserver docs]# ls -ahl /dev/hda brw-rw1 root disk 3, 0 Apr 11 16:25 /dev/hda I can't just put dumpuser into group disk as that wil give it full read write access. I don't think it wil be a good idea to revoke write privelages from disk ;-)and it will not be a good idea to change the group.So what now ? This is what stumps me. Tnx all Mozzi
Re: Working with multiple tape drives----- Ammended
Reply With History On the library, sometimes due to transportation (and the library was not "Park" properly), the robot arm tends to miscalculate its "Y" position. That is when you need to re-calibrate. By re-calibrate I meant accessing the menu on the library and manually calibrate. On the units that we (Tandberg Data) sell, there is a special menu where you can select to manually calibrate the robot arm. This menu is NOT for normal user use, therefore its need a combinations of keys presses to make it appeared. What I would suggest for you to do is to get the manual for the library you have, maybe there is a section in there that tell you how to recalibrate. If not then you need to contact the support section. Regards Tien

I was a bit tricky but I managed to make this work with Amanda 2.4.3b2 and W2K clients (not NT4). The major problems in fact were to transform this slight piece of code into a W2K Service (to make it work even if you have not an Administrator account always opened) (quite a bit tricky to to find information at Microsoft's). Another problem was due to the Windows flag "archive" that seems to be read by Amanda exactly like the Unix "executable" flag. Now I am backuping some W2K servers, in production.
