Re: amanda-2.5.1p3 ignores no-reuse

Using virtual tapes on USB disk, it seems to be fast enough (20 to 40 MBps) depending on the hardware, the speed of the holding disks, etc. Faster than the dump, so no problem. The problem is the following: I have 3 USB disks for virtual tapes, and only one is connected at a given time, so in tapelist I marked the tapes that are not accessible with no-reuse. They cannot be used because the disk is not online. Despite, the report at the end of a dump mention that amanda will try to use these; These dumps were to tape CSIM-set-1-06. The next 5 tapes Amanda expects to use are: 5 new tapes. The next 5 new tapes already labelled are: CSIM-set-1-07, CSIM-set-1-08, CSIM-set-1-09, CSIM-set-2-01, CSIM-set-2-02. The tapes CSIM-set-2-01, CSIM-set-2-02 are on a disk that is not online and they are marked no-reuse: 0 CSIM-set-2-02 no-reuse 0 CSIM-set-2-01 no-reuse 0 CSIM-set-1-09 reuse 0 CSIM-set-1-08 reuse 0 CSIM-set-1-07 reuse Is that a feature? I think you've hit an outlying situation. One that is so uncommon that it was not considered during design and coding. Note that nothing that amanda says in the report are inaccurate. It expects 5 new (labelled and previously unused) tapes. Further, it peeks at the tapelist file and notes the next five that match those criteria, labelled and unused. I wonder if the developers ever considered that a newly labelled tape (one with a 0 for last date used) would also be marked no-reuse. I realize I'm playing with semantics here, but would it be wrong to use for the first time a tape marked no-reuse? Maybe not as the first use is not a reuse. ;) Note also that amanda has not actually tried to use these marked tapes. It is just reporting current conditions. You may unmark those no-reuse tapes before the next amdump. Even if you don't, amanda will go further into the tapelist and online available tapes looking for ones it can use. Should it not find enough it will enter degraded mode and backup to the holding disk without taping. -- Jon H.

Amanda on Macos X
Hello, I installed amanda on macos X. I followed the instruction of this page : Installation/OS Specific Notes/Installing Amanda on Mac OS X All is ok. I compiled the source and installed the program. But, on leopard, what is the next step ? In the documentation, there is this sentence : Leopard At least one user is successfully using Amanda on Leopard, though he is using SSH authentication, not BSD*. (I am testing with BSD, passed amcheck phase, will see how the backup goes tonight (08/20/2008)) Ok for the authentication but how do you run the amandad server ? Like Tiger ? thank you for your help Julien
Syntax error in chg-disk
Hi, I am using chg-disk on Amanda 2.5.1p3 on FreeBSD and while I was trying it by hand, I found a Bourne Sheel syntax error: around the line 83, it should read: if test X$TAPE = X; then With a single = instead of the == operator found in the script. I am not sure it is an error in Amanda distribution or in the port made for FreeBSD. Best regards, Olivier
Changer policy
Hi, I have a brand new Amanda server, that uses virtual tapes. My virtual tapes are set on external hard disks, but I can only physically connect one disk at a time. I uses runtapes 5. So I can end up in a situation where I have 2 vtapes left one a disk, and where I must change disk in the middle of a dump. I beleive this is close to the situation of a tape caroussel, where one wants to reload the caroussel in the middle of a dump. I'd like to know if the model bellow makes sense with Amanda, does it break the general idea or not? Will it work if I write a changer that would wait for manual change of the disk? The dumps would finish to the holding disks and the taper would wait for manual change of the disk before finishing to write on the tape (wait would be several hours). I see that amcheck physically tries to access the tapes, so in a situation with 2 tapes left on a disk and 3 tapes from the new disk, amcheck would request the user tou change disk, that is not really necessary, is there any other command that is likely to access the changer (beside the amdump/amflush and restore). Is there a command to get the label of the tape loaded in the tape device? Does it exist a changer that allow the manual change of a caroussel, so I don't have to redesign everything from scratch? (I mean the Amanda phylosophy, not the exact way to load/eject a caroussel or mout/unmout a disk). Best regards, Olivier

I *think* that chg-manual will do what you want, perhaps with a little bit of tweaking to recognize when vtapes are on the same disk. This is a fairly common use-case, so if you're working against 2.6.0, I'm sure a lot of other people would like to see your solution. Dustin -- Storage Software Engineer http://www.zmanda.com

My setup is probably similar except I have 2 usb drives plus some space on the hard disk for my vtapes. However I don't typically unplug the external drives. My changer slots are actually symbolic links to the actual location of the mounted vtapes. If a drive were off line (or more frequently in my case too full) amanda just looks for the next available vtape. If none are available it finishes to the holding disk like you suggest. I wonder if an modified changer script is even needed. If you have the auto flush parameter set in amanda.conf, the next time you run amdump it will check the holding disk and begin flushing the old dumps immediately. I think this begins even while estimates are being done. So just bring online the other drive and let amanda do its thing next amdump. Is there a command to get the label of the tape loaded in the tape device? From memory, amtape ... show or current. Does it exist a changer that allow the manual change of a caroussel, so I don't have to redesign everything from scratch?

But I had 7 magazines of tapes and never noted a changer script that automatically or manually tried to deal with magazines/caroussels. -- Jon H.

Re: Changer policy
Oliver, The simple answer is to use chg-manual, which waits for operator intervention. You will have to adjust a symlink as well as the disk connections. If it is possible to script the disk switch, you should be able to write a changer script that does what you want. --Ian On Thursday 21 August 2008 08:55:26 Olivier Nicole wrote: Hi, I have a brand new Amanda server, that uses virtual tapes.

Re: amanda-2.5.1p3 ignores no-reuse
As Jon said, it's a problem with new tape marked as no-reuse, only the
report is bad, amanda will works as expected.
The attached patch fix 'amadmin CONF tape' and amreport.
I don't know if the patch apply to 2.5.1p3.

Hello,
I am setting up a new Amanda server.
Using virtual tapes on USB disk, it seems to be fast enough (20 to 40
MBps) depending on the hardware, the speed of the holding disks,
etc. Faster than the dump, so no problem.
I am currently hit by the IPv6 only problem on the client side, but
that one I identified and hope to solve it by reinstalling amanda for
IPv4 only.
The problem is the following:
I have 3 USB disks for virtual tapes, and only one is connected at a
given time, so in tapelist I marked the tapes that are not accessible
with no-reuse. They cannot be used because the disk is not online.
Despite, the report at the end of a dump mention that amanda will try
to use these;
These dumps were to tape CSIM-set-1-06.
The next 5 tapes Amanda expects to use are: 5 new tapes.
The next 5 new tapes already labelled are: CSIM-set-1-07, CSIM-set-1-08,
CSIM-set-1-09, CSIM-set-2-01, CSIM-set-2-02.
The tapes CSIM-set-2-01, CSIM-set-2-02 are on a disk that is not
online and they are marked no-reuse:
0 CSIM-set-2-02 no-reuse
0 CSIM-set-2-01 no-reuse
0 CSIM-set-1-09 reuse
0 CSIM-set-1-08 reuse
0 CSIM-set-1-07 reuse
Is that a feature?

Try 'ssh [EMAIL PROTECTED]' from your amanda user on the server and see if that works, or if it still needs to add the host key for the fqdn. -Darrell

Re: Problem Backing Up NFS SmartStor
Hi, I have a Promise SmartStor, a network drive. It's NFS mounted on a Red Hat server. Sometimes it gets backed up, other times I get: whimsy.med.utah.edu/sstore/9gb lev 0 FAILED [dumper returned FAILED] whimsy.med.utah.edu/sstore/9gb lev 0 FAILED [data timeout] whimsy.med.utah.edu/sstore/9gb lev 0 FAILED [cannot read header: got 0 instead of 32768] whimsy.med.utah.edu/sstore/9gb lev 0 FAILED [too many dumper retry: [request failed: timeout waiting for REP]] Just a wild guess, but a Google search yesterday on cannot read header: got 0 instead of lead me to problems with IPv6/IPv4. I recompiled Amanda to use only IPv4 (./configure --without-ipv6) and the problem is gone. To further diagnoze the problem, look at the debug files, you would see that one side of Amanda opened a socket on IPv6: amandad.20080821100912.debug:amandad: time 2.679: stream_server: waiting for connection: ::.51629 while the other side try to connect on IPv4: dumper.20080821100912.debug:dumper: connected to 10.41.170.14.51629 I used information from http://archive.netbsd.se/?ml=pkgsrc-usersa=2008-02t=6414321 As you don't mention anything about the operating system of the server and the client, I don't know if that helps. I am running FreeBSD 6.3 on both sides. Best regards, Olivier
What tapedev is used by Amanda
Hi, Does Amanda use the tapedev defined in amanda.conf or the tapedev returned by the changer? If Amanda uses the tapedev returned by the changer, I think that chg-disk could be rewritten to avoid using symlinks, returning the directory of the slot each time, and so could work with file systems that does not implement symlinks (NTFS/FAT32 USB disks). Best regards, Olivier

What makes it confusing is that some changers return the tapedev defined in amanda.conf :) If Amanda uses the tapedev returned by the changer, I think that chg-disk could be rewritten to avoid using symlinks, returning the directory of the slot each time, and so could work with file systems that does not implement symlinks (NTFS/FAT32 USB disks). Yep, sounds like a good plan. Dustin -- Storage Software Engineer http://www.zmanda.com
