Re: Ultrium LTO tape drive
Have you done (are you doing) backups with different programs (Arkeia, taper, tar etc) or other OSes than linux? No. Yes. :) yes, yes If yes, what is your experience about backup speed? Amanda is slow, compared to ufsdump/tar straight to tape, because amanda does a lot more. If using a holding disk, and having 2 - 4 fumpers dump to holding disk, and from holding disk to tape, you can get approx 11/12 Kbps (4 dumps at 2 -3 Kbps to hodling disk and from HD to tape at 11/12 Kbps) LTO rules ;) Kind regards, -- Gerhard den Hollander Phone +31-10.280.1515 Technical Support Jason Geosystems BV Fax +31-10.280.1511 (When calling please note: we are in GMT+1) [EMAIL PROTECTED] POBox 1573 visit us at http://www.jasongeo.com 3000 BN Rotterdam JASON...#1 in Reservoir CharacterizationThe Netherlands This e-mail and any attachment is/are intended solely for the named addressee(s) and may contain information that is confidential and privileged.

Re: Holding disks getting full ..
* Alexandre Oliva [EMAIL PROTECTED] (Fri, Apr 20, 2001 at 11:08:36AM -0300) So it looks like amdump checks if there is enough space on the holding disk before it starts dumping, Yep. and then simply continues dumping whitout checking if the holding disk becomes full, until it runs in a diskfull error and aborts the dump. It would fall over to another holding disk, if you had one. The right thing (imo) would be to check every time a new chunk is written, and if the chunk to be written would fail the holding disk free space criteria, it should abort the dump. And end up aborting the dump anyway? What's the advantage? 1) it's quicker Aborting a dump after 3 G has been written to disk, or aborting after 4G has been written does make a difference. 2) It prevents diskfulls from happening, some other programs are suign the disk for (very small) scratch space, and they fall over if the disk is full (yes, I know, fix those programs ;) ) ... 3) The Right Thing (tm) if you have multiple hodling disks is t check before starting to write the chunk whether you're below the watermark, and if the next chunk would bring you below the watermark, switch to the enxt holding disk. No errors, no errors in the syslog.

Backup of large disk arrays with AMANDA?????
Dear Sirs. I run into problems with AMANDA backing up a large disk array (250 GB). I use 'gnutar' as dumping tool defined by GTAR within amanda in the hope that AMANDA is capable to spread a big backup image over several tapes like TAR does this when used without AMANDA (multi volume facility). I asked about AMANDA's capabilty of backing up large arrays before and I was told to split the big array into smaller pieces. It seems to me, by the way, that AMANDA is only capable of backing up arrays or drive areas they are about the size of one tape. We use a tape changer with 6 slots of DDS-4 cardridges. But the suggestion splitting up the big array into pieces is impossible! The only way I could do is to order users in alphabetical order and save them splitted (the big array is the HOMES partition of our institute). But several users have enormous data fluctuations, today I run into problems with the daily backup due the fact one of the users load scientific data of about 30 GB - that is to much for one tape and since 8 hours amanda is trying to back up this area trying each tape, filling it up to its limits, then makes an error and take the next tape - a silly behaviour. Well, I would like to ask for some hints or simply a fact-statement: Is AMANDA capable of spreading a large volume over several tapes with gtar like gtar does this using the multivolume mechanism? How to configure this ability if possible? Please be aware of the following fact: I definitely can not split this array into smaller pieces because it is not possible to split them due the high data fluctuation.

Amanda-242-tapeio and IRIX
Hi, I'm Arjan Molenaar, a Dutch sysadmin and currently implementing a backup scheme based on Amanda. This morging I checked out the Tapeio branch of Amanda. I noted that it did not compile due to a typo in tape-src/tape-output.c. Browsing the mailing list archive I came across a patch that fixes it: http://groups.yahoo.com/group/amanda-hackers/message/2519 It probably slipped through... And I am wondering: how stable is the tapeio branch by now? Are there any changes to be expected in the near future? Thanks in advance, Arjan PS. please CC me since I am not a mailing list member.

Re: Amanda-242-tapeio and IRIX
This morging I checked out the Tapeio branch of Amanda. I noted that it did not compile due to a typo in tape-src/tape-output.c. ... Oops. I guess I forgot to finish up installing that patch. It's now in the CVS tree. Thanks for reminding me. And I am wondering: how stable is the tapeio branch by now? Are there any changes to be expected in the near future? It's pretty stable (as in, I haven't messed with it for weeks). However, I don't use the code and don't know if any one else does either (or rather, how much of it, since I suspect Marc uses the RAIT stuff in production). So you should consider it under development. I will be making a change soon to shift some of the tapedev parsing code from output-rait to someplace it can be used in general, but that should not have a major impact. Arjan John R.

custom barcode labels
For those of you with tape changers and barcode readers: are any of you using any software to generate your own custom barcodes? It seems like it might be a bit nicer (for locating/moving tapes around) if the barcode label could match what the tape label has. I've only tried two pieces of software so far (BarCode Maker 3.0) and something called barcode 97 for windows 3.1. They both create barcodes OK, but for some reason my Qualstar tape library won't read them. (Maybe I'm doing something wrong, though-- I'm printing them out on regular paper, and then taping them to a test tape to see if the bar code reader can scan it. Ideas? -ron

Re: custom barcode labels
Hi Ron, I have a Brother P-touch 540 Extra that I use for making tape labels which also does several types of barcodes. However, someone else will have to verify whether the P-touch barcodes work with a changer or not because my changers don't read barcodes. I find using the P-touch a whole lot easier than printing out a whole sheet of labels from a printer, trying to find the right size labels or cut them to size, and trying to get the layout right. The only thing I don't like about it is that 9mm is the narrowest label size which is a little too wide for a 4mm tape. Perhaps Brother has some other model that supports a narrower width.

Re: custom barcode labels
When you tape them, are you covering over the barcode as well? I'm not sure about all barcodes, but the one on my ADIC will not read one that has tape over it. You may want to check the docs with your reader, which should give the requirements for barcodes it needs.

That's the answer you gave me about 3 weeks ago when I asked what does this runtapes thing mean? :). If your device has cartridges that hold 22 tapes, that can cause things to get shifted so you don't swap the cartridges at nice points. I've thought about it. It won't be as automatic as we want, but a) we'll probably be backing up 2 tapes worth soon anyways b) the sysadmin will just have to move tapes with a little more intelligence :. Another option is that the ADIC doesn't have a tray or anything. The tapes go into their own little slots. Thus, we can just swap out the ones we know we've already used from cartridge 1 and put in cartridge 2 tapes in their place. So long as amanda is convinced that it is a gravity stacker and doesn't go backwards (your advice, again). Thus, he can take out the first 10 tapes when amanda gets to tape 11 and put in 23-32 there. Then, when it starts sucking from the 23 bank, put in 32-44. Thanks for the advice, Mark -- http://www.mchang.org/ http://decss.zoy.org/
