Requesting Backup Level of 10
Hello, Using amanda-2.4.2p2 I got an error from the planner telling me planner: FATAL error [planner askfor: lev out of range -1..10: 10] - the maximum dump level is 9, so the message should be ... lev out of range -1..9: 10] ^ - how can this happen? Bug? My error in amanda.conf? 2.4.2p2 worked for months if not years w/o any problem now. Maybe it's the bumpsize 20 Mb bumpdays 1 bumpmult 2 statements in my amanda.conf?

netusage parameter in amanda.conf
Hello, Does the netusage parameter in amanda.conf really work ? I am asking this because I have changed it to 50 kByte/s and still see the backups taking the same amount of bandwidth on the MRTG graphs of the backup server... Regards Marc
Re: Exabyte EZ17 Autoloader
hi jerry, i've been using an ex17 autoloader under various version of solaris (2.6 and 8) for the past 3 years. you WILL need to modify /kernel/drv/sgen.conf so that the device will be recognized, you basically need to add the following lines: device-type-config-list=changer; name=sgen class=scsi target=1 lun=0; # which target is the scsi id. comment out all other lines. you can then run devfsadm -i sgen to load up the driver. you should then have a /dev/sgen@1,0:changer device, which is a softlink to /devices/pci@1f,0/pci@1/pci@3/SUNW,isptwo@4/sgen@1,0:changer, or something similare. you will need to compile and install mtx, http://mtx.sourceforge.net. i've been using version 1.2.10 with great success. you also need to use the chg-zd-mtx scripts for amanda to control the device. i've made segnifagent modifications to the script for it to handle the device, if you want my hacked version email me and i'll mail it to you. the cfgadm(1M) command is used on sun enterprise server to dynamically reconfigure hardware on the system. you use it to take system boards, processors, memory in/out of service. you don't need to use to for amanda, unless you're adding an I/O tray and scsi controller to a machine on-the-fly.

I have some dusty neurons in my head that recognize this from previous postings. There is so much dust that I can't be sure I'm remembering ancient history correctly. Don't shoot me if I'm off-base. Something is happening to prevent your getting back to a level 0. Maybe the size is now greater than a single tape or some such. That is its own issue. For most of amanda's life, it never gets anywhere near level 9. So the code related to it is almost never exercised/tested. The conclusion was that yes there is a bug that doesn't check if the level is out of range high. I doubt that anyone ever went back to 2.4.2 to fix the problem as it happened so seldom, and only under situations caused by other problems. Fix the reason why it is not able to do a lower level dump, and while the bug will not be fixed in the code, you won't hit it anymore. Cough, Hack, Gasp.

You could also just create the DailySet1 directory, make a copy of your disklist and amanda.conf, update the paths and labelstr in the new config, label tapes for it, and just start running the new config instead of the old one. Then you would have the old backups to restore from if you need them. Later on you could relabel the old tapes and add them to your new config. i will try this. 3. why does amdump refuse to mail the backup reports to me, when i put this line in amanda.conf (remove CR/LF to get one line): columnspec HostName=1:-1,Disk=1:-1,Level=1:-1,OrigKB=1:-1,OutKB=1:-1,Compress=1:-1, DumpTime=1:-1,DumpRate=1:-1,TapeTime=1:-1,TapeRate=1:-1 i think, this should give me 10 columns, each with one space on the left and the width dynamically resized to fit the largest entry. I've never used the negative entries, but assuming that they normally work I would take a wild guess that it might be the 'Level' column, since that is always 1 character wide. Since you only need to specify the columns you want to change from defaults, try just modifying one column first, see how that runs, then add one more, etc., till you get it like you want or find what breaks it. amreport is segfaulting with this columnspec. i changed it to read columnspec Disk=1:-1 now it runs fine. thanks

comment all lines in sgen.conf with the exception of device-type-config-list=changer; name=sgen class=scsi target=0 lun=0; then unload the module and run devsfadm again. if devfsadm didn't error with failed to attach then is should create the device files. i'm guessing it's not there due to the other lines not being commented in sgen.conf.

The exclude can be a single definition within the dumptype section of your amanda.conf, or you can point it to a file with many names in it. The one universal specification is that the name so given must be a 'relative' name, eg /tmp will not work, but ./tmp will.

Recommendations on Execution
I have a 140G RAID5 array that I would like to back up to my 20/40 DDS4 Seagate drive. Without a lot of experience with a drive this large, I've made a 100M /boot partition, a 2G swap partition (I have 1G of ram), and finally the rest of the drive ~137G set to /. I've allocated 20G to /tmp for a holding disk. I have set it to back up / every day. I have 5 tapes. I guess I should exclude /tmp and /var/tmp from the backup list so that it isn't backing up the tar file as well. Any other recommendations on this setup.

Re: Recommendations on Execution
Just a recommendation (outside of backup really) but you should make your 137G LVM controlled so you have to power to control where it goes. I would make / like 5 GB or whatever you like, but use the rest of the space for various filesystems like /home /database /usr/local and make them LVM controlled--- I love being able to make my 50GB space useful by extending the filesystem only as I need it, and you don't end up with all your eggs in one basket... man that would suck if you had filesystem issues on / Jerry --- Thom Paine [EMAIL PROTECTED] wrote: I have a 140G RAID5 array that I would like to back up to my 20/40 DDS4 Seagate drive.

kswapd goes nuts!
My backups have recently slowed down... It is very peculiar and just started recently what seems to be out of the blue. The network clients are backing up at full speed but the file systems on the dump-host itself have slowed to about one quarter of their normal speed. I am using dump (as opposed to tar) and what I have observed is that a top shows kswapd and kreclaimd using 80% to 100% of the CPU when dump is running on the dump-host. I am running a dual 1Ghz PIII with 1G ram on the dump-host and top shows little (or no) swap space being used (though all of memory is used, but Linux does that no matter what). I am running redhat linux 7.2 with kernel: 2.4.7-10enterprise #1 SMP Thu Sep 6 16:48:20 EDT 2001 i686 unknown I am running: amanda-2.4.2p2-4.i386.rpm dump 0.4b31 (which is the latest dump according to: http://dump.sourceforge.net) I can't figure out what is causing kswapd and kreclaimd to go crazy when the dump program runs, and it only happens on the dump-host. The other 5 remote systems are all running Linux 7.2 or 7.3 and dump doesn't cause them any problems. I.e. kswapd doesn't even show up in a top on the remote machines when dump is running. Has anyone else ever experienced anything like this? Any suggestions what I can try to fix it? (Please don't suggest I use tar.) :) Let me know if I can provide any other details of interest.

Re: kswapd goes nuts!
I have observed the same thing on several Linux boxes. It seems to be a result of the changes made to the virtual memory manager code in the mid 2.4 kernel series when using multiple processors. 2.4.7 sounds like about the time it started, but I don't remember exactly. We actually killed kerneld on a few machines and ran without swap for quite awhile (they did have 2 - 4 gigs of ram in them, so they didn't really need to swap). The bugs were ironed out of the kernel code sometime later (I think early or mid teens) but are definitely fixed in the last few versions (2.4.18 and 2.4.19), so I would recommend installing one of those. Look in the changelogs on www.kernel.org if you need to know the exact versions to use or avoid. It wasn't a distribution- specific problem, we had both Red Hat and Debian boxes with the same problem, and a new kernel was the cure for both. Amanda seems to bring out the problem since there are multiple processes simultaneously trying to allocate rather large buffers.
