Re: Using only one tape, full dump delayed
Ok Guys You're so smart and kind. I do hope 'dude' is not too rude (since it's not my native language). I found it after disassembling the drive (some of you may have a notch at the bottom of the case, the SUN-Version does not). BTW it does work fine for days already, and I like it.

Perhaps unintentionally :)) What tape drive do you really have? If I recall correctly, the SureStore-1200 is a DDS2 (DAT-2) changer and you were using a reasonable (3.9GB) tapetype definition for that. But you were using 125M tapes, DDS3 tapes that should not work in a DDS2 drive. Actually, has anyone ever tried that? And for sure, even using a 5M longer DDS3 tape with a DDS2 drive, I don't think would not get anywhere near the 8GB capacity you seem to be getting. Unless you can write to DDS3 formula tapes in a DDS2 drive AND we consider your other lie :) 4.) is hardwarecompression active in your tapedrive? No, disabled by using device /dev/rmt/0bn (b= berkley mode n= no compression) Based on device name I'm guessing this is a Solaris or HP system. In either case, n refers to No Rewind, not no compression. By chosing the 0 device with no density modifier (like l, m, ...), you have elected default compression, which generally is on. So maybe, if you are using a DDS2 drive, a DDS3 tape, no software compression, and hardware compression, you can get 8+GB of data written. What are you actually doing? BTW using the Berkeley drive options is not recommended. -- Jon H. LaBadie [EMAIL PROTECTED] JG Computing 4455 Province Line Road(609) 252-0159 Princeton, NJ 08540-4322 (609) 683-7220 (fax)

Re: Using only one tape, full dump delayed
From: Christoph Scheeder [EMAIL PROTECTED] Hi, first : simple answer, simple question, and amanda is telling it to you: amanda thinks the level 0 dump of this filesystem will not fit on a single tape. That's understood. Amanda can not span a single disk-list entry over multiple tapes. you'll have to split it up using excludelists and tar. [...] NOTES: planner: pbrazor1.tszrh.csfb.com /ora 20030226 0 [dump larger than tape, full dump delayed] [...] second: these values will give you problems. There are 6 Tapes in the changer; dumpcycle 1 weeks runspercycle 5 tapecycle 6 tapes runtapes 3 you want 5 runs per week, each using up to 3 tapes. This tells amanda: do a level 0 for each filesystem at least every 15 tapes. but a little later you tell her she only has 6 tapes in rotation. this is a NoNo with amanda. either lower your dump-cycle or get more tapes. runtapes should be at least one tape bigger then runspercycle x runtapes, or amanda will get confused about when to do a level 0 of your disks. OK, I see the problem, but not the solution yet ;-) There are 6 Tapes in the changer and I dont want to swap these. It is supposed to be sort of unmaintained forever. - If I put runtapes 1: will it still use more than one tape if needed? - If I put runspercycle 3 and runtapes 2 then I still would need 7 Tapes... - If I put runspercycle 2 and still call it 5 times: will it confuse amanda? I know I could find out trying but it would take ages. if you want only level 0 backups, you should set dumpcycle to 0. Christoph

Since amanda cannot span a single DLE across more than 1 tape, she is apparently refusing to do it. You will need to break that DLE down into subdir listings, such as, /dev/dsk/c0t0d0s0/home /dev/dsk/c0t0d0s0/etc /dev/dsk/c0t0d0s0/whatever in order to get its present estimated size of 8,758,612 broken down into pieces that will fit on a tape. Then when it hits EOT while writing one of the smaller DLE's, it should unload that tape, load the next and restart that unfinished DLE from its beginning on the next tape. If it refuses to do the smaller entries, then there must be a permissions problem of some kind. From the other warnings issued it looks as if you are doing samba shares instead of installing the amanda clients on those machines. I tried that for about a month, and gave up on using samba which has gotchas going clear back to dos days.

Re: Using only one tape, full dump delayed
Hi, now let's get some information to sort out varios things: 1.) what length are the tapes you use: 120 meter or 125 meter? 2.) how often do you want amanda to take level0 dumps of your data? once a week? 3.) how many data do you need to backup? 4.) is hardwarecompression active in your tapedrive?

I know I could find out trying but it would take ages. if you want only level 0 backups, you should set dumpcycle to 0. Christoph
Re: Using only one tape, full dump delayed
Hi, now let's get some information to sort out varios things: 1.) what length are the tapes you use: 120 meter or 125 meter? 125m / 410 feet (12.0GB) 2.) how often do you want amanda to take level0 dumps of your data? once a week? Does not matter, as long as at least one full dump is on one of the 6 tapes... 3.) how many data do you need to backup? ~15GB presently (2 Machines, 12 Partitions). Will not grow much. 4.) is hardwarecompression active in your tapedrive? No, disabled by using device /dev/rmt/0bn (b= berkley mode n= no compression) Urs Christoph [EMAIL PROTECTED] schrieb: From: Christoph Scheeder [EMAIL PROTECTED] Hi, first : simple answer, simple question, and amanda is telling it to you: amanda thinks the level 0 dump of this filesystem will not fit on a single tape.

It must be bigger than 3900 mbytes after amanda compresses it, so it won't fit on a single tape. Amanda doesn't span tapes, so you'll have to split this up with tar. What am I missing here Matt? Thats not the same DLE he quotes at the top of the message, so how does that become reconciled? Not trying to be nibby, just curious :) There's only one /ora in his dump summary...I was working on the assumption that the output from df at the beginning of the message is the same partition. It looks to me that it is an ~8.7GB partition with ~6.8GB in use and ~1.8GB free. Obviously 6.8GB isn't going to fit on a 4GB tape, but compressed it might have at one point in time. It's just not anymore. So the way I see it he'll have to split /ora up with tar, no? Yes. :-) -- Cheers, Gene AMD [EMAIL PROTECTED] 320M [EMAIL PROTECTED] 512M 99.24% setiathome rank, not too shabby for a WV hillbilly
