I'm not aware of Bacula compressing data from the client when sending it to the tape drive unless you explicitly enable it. And it's generally not worth doing. The key thing with DLT is to push data to the drive at a high enough rate to keep it from shoe-shining. That both wears down the drive, and kills performance/storage capacity. Since the native speed is 5MB/s, you really really really wnat to be able to push 10MB/s to the drive to let it compress the data well. Unfortunately, that can be hard to do, esp if you have lots of small files to backup. Also, check your dmesg output to see how the drive is detected and at what speed it's running. When you put a tape into the drive, does the compression light come on as well? There's a known limitation (performance bottleneck actually) where Bacula uses transactions for inserting records into the DB one at a time. If they could insert more records at a time, performance would go up since the transaction overhead would be amortized across more INSERTS. Also, which DB are you using? And which version of Bacula? The newest released version I think (and I'd have to check) now uses sqlite3 as the default DB, which has a big performance loss compared to older 1.36.x versions which defaulted to sqlite which had better performance. Now one of the things I did to speed up my backups was to put my DB onto another host, since my tape drive and data were all one one system, so adding mysql updates ontop of that really just brought it down to it's knees. Anyway, more data on your backups and how well they currently run would be good. On my system, I get around 24gb to 68gb per tape, so it's certainly possible to get more data on there, esp since I'm using a dual CPU Xeon 550mhz box to do my backups. Old and not very fast. John

Should it read DTL7000 or > something? Bacula doesn't actually parse the media type - it's nothing more than a unique identifier string that bacula uses to determine what volumes can be read by what drives. You could call file volumes "blue", DLT tapes "red", and DVDRs "green" and it would work fine. Bacula doesn't try to pre-determine the amount of space available on a tape. It just writes until the drive reports that it's hit the end of media, re-reads the last succesfully written block to make sure it got there okay, marks the volume full and asks for another one. The fact that you're getting about 30G of data per tape implies that you have hardware tape compression off. I believe the 'mt' command will tell you the compression status - the online manual has an example. The other 5G or so is probably taken up by volume metadata, such as the volume label and file attributes. > Also, does bacula compress naturally or do i have to tell it too? No, you have to explicitly enable gzip compression if you want to use it. It's typically reccomended to use drive hardware compression instead, though, as a) drive hardware compression is usually faster, especially on older machines, and b) it's possible to run into file daemon incompatabilities that can make it difficult to restore data, especially if you're trying to restore the data onto a different machine that the one it was backed up on. -- Frank Sweetser fs at wpi.edu | For every problem, there is a solution that WPI Network Engineer | is simple, elegant, and wrong. - HL Mencken GPG fingerprint = 6174 1257 129E 0D21 D8D4 E8A3 8E39 29E3 E2E8 8CEC

Yup, it's the MAC address of the upstream ethernet device. Basically, all packets are sent to that MAC address when they go off your network. Basically, what happens is that when you try to goto a new IP address (or when a new IP address attempts to contact you), the low level ethernet stack sends out an ARP (Address Resolution Protocol) request, saying "Who has this IP?" and waiting for a response from some other device. Be-it a bridge, a switch, an actual host, or whatever. This is how the low level ethernet knows where to forward packets within it's network segment. Each hub has just a single MAC address for all it's ports. A computer should have a unique MAC address for each ethernet port, though Suns didn't do this for a long time. The idea was that you couldn't put two seperate interfaces on the same network, since it caused problems. Obviously this was also on bridged networks, not swiched ones, which are the standard today. For network switches, each port has it's own MAC address. Basically, every device on a network (low level, physical medium) has to have a unique MAC address, otherwise you run into problems. This is layer 2 stuff. Layer 1 is the physical media. TCP/IP are layers 3 and 4 respectively. Hopefully this helps. I know I've skipped some details here. John

Re: [Wlug] iptables use of --mac-source

by Justin Odom

Andy, MAC Addresses work at layer 2. When a router receives a packet, it strips off the mac addresses, looks at its destination, appends its own mac addresses, and forwards out the appropriate interface. The MAC your seeing is probably your ISP's router.

ALSA - mic trouble

by Eric Stein

Hi, When I first set up my Ubuntu machine, everything worked fine. But for the last few months (I don't remember exactly how long), my mic has refused to work. Nothing I use can pick up any signal from it. I've tried all the mixers (alsamixer, kmix, the built in GNOME mixer), and none of them show the mic as muted. Is there a way to reset ALSA's volumes and other mixer settings to defaults? I can't seem to find information about this online, and this lack of a fully working sound system has me on the end of my rope. Info: Ubuntu Breezy 5.10 Linux pippin 2.6.12-10-386 #1 Tue Jul 18 22:08:27 UTC 2006 i686 GNU/Linux I'm prepared to spend a good deal of time on this, but I don't know what I need to do. If you need more information, let me know how to get it and I'll be happy to share it. Eric

My memory leak problem.

by ken jones

Everyone: It is hard to believe that X is the problem. It came with Fedora 4 and no one else seems to be reporting it as a bug. I have another Fedora 4 machine that does not display this swap space problem. Karl's idea of looking carefully at my drivers is a good one. This machine has more than one special driver. It is late now. I am tired. I shall pursue this track tomorrow or Friday. If anyone else is interested in the cut and paste of ps auxw lspci uname -a lsmod vmstat dmesg tell me. I will send you a copy. Thank you all:-) Ken Jones Thank you.

Keep watching this process if it's memory size grows then there may be a memory leak eating up your memory.. I'm not a fedora expert, are there any X updates? have you run yum or updated your system? What version of X are they using? perhaps send your /var/log/xorg.0.log [root@kjones-fedora kjones]# lspci 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R300 NE [Radeon 9500 Pro] 01:00.1 Display controller: ATI Technologies Inc Radeon R300 [Radeon 9500 Pro] (Secondary) I see you have an ATI graphics card. Do you know what video driver you are using? perhaps there is a problem there.

The graphic didn't come through here. I bet you're using a binary-blob kernel module (e.g. Nvidia) which is making your system crash. The other possibility is you have an app with a memory leak, using 'ps avx' would help diagnose that. --Andre __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Should be able to see what the cause is. send us more info on your system do these commands and paste us the results: ps auxw lspci uname -a lsmod vmstat dmesg

I have setup a few servers with 1TB, 1.5TB and 2TB doing NFS, mainly for video streaming and at most 15-20 NFS clients. Using kernel 2.6.15.7 for a while now with no performance complaints. I have seen 15 NFS clients streaming DVD quality mpeg2 video (9mbps) work nicely. Getting over 2TB, tho starts to be a lot of disks and there are heat problems, also problems finding enough drive bays. -- Karl Hiramoto http://karl.hiramoto.org/

Getting a box with a bunch of 3ware controllers talking to SATA drives in hot-swap bays might be the ticket. You'll get decent performance too, though not stellar. Software RAID can be faster, but the 3ware can/should insulate you from the hardware hot-swap issues. Should. Take a look at JetStor, or the ATAbeast boxes. They were around $14k/2Tb three years ago, so they must be cheaper/better now. What about backups? John
