[Bacula-users] DLT 40/80GB never reaches 40GB
Hi All, I have this problem where I've got a mix of 20/40GB and 40/80GB DLT tapes that are in 1 pool configured to backup using 1 tape drive. The problem is, all of them seem to be acting like 20/40GB tapes including the higher capacity ones. I've not been able to get the 40/80GB tape to store even remotely near 40GB let alone the compressed capacity of 80GB. I was wondering whether anyone had similar problems before... The funny thing is, I've got a another pool that uses another tape drive that all backup correctly. Most backup are close to around 68-72GB, which I believe is fine. I've configured both pools devices similarly but don't know why 1 only backs up to around 34GB (acting like a 20/40). Both tape drives were bough at the same time and are identical models. Is the mix of tapes causing the problem? They are currently listed as /dev/nst0 and /dev/nst1 respectively. Is there any configuration files in outside of bacula-dir that I need to configure or perhaps in Linux system files perhaps, although I don't recall any configuration files other than the bacula conf files where done back during the initial setup. Thanks!

Re: [Bacula-users] DLT 40/80GB never reaches 40GB
Hi Phil, No worries, I've checked that both are DLT2 drives. Specifically they are HP SureStore Autoloaders. Both were bough at the same time from HP directly. They were also configured identically. We initially had a bunch of DLT tapes around (10 or so) from our old HP server which had an inbuilt DLT drive. This was DLT1. When we purchased the 2 Autoloaders we wanted to reuse some of the old tapes rather than junk it since we're using bacula as network backup. We also purchased well over 30 DLT 40/80 tapes. Interestingly, I've relabeled a 40/80 tape that was originally in the pool that backed up from pool1 (the one with the problem) and put it into pool2 (working normally) and it works correctly. I thought about the physical tape drive causing the problem but I've nowhere to check? Is there any way to check using software? I'm not certain how this actually works out. Since both autoloader are bought together and are from the same batch, 1 couldn't have been DLT1 while the other DLT2. I ruled out the autoloader as the source of the problem since it's still working. It's unlikely a hardware fault could cause something like that... however I could be wrong. I'd like to explore software configuration issues before accepting the drive is faulty. From my previous experience, the drive either works or don't. I've never encountered an issue where it slows down but still works Thanks!

This may be a silly question, but .. You've stated you have a mixture of DLT1 (20/40GB nominal) and DLT2 (40/80GB nominal) tapes. Are your drives DLT1 or DLT2? A DLT1 drive will only get 20/40GB capacity from a DLT2, DLT3 or even DLT4 tape. --- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
[Bacula-users] Re: How do I move tapes accross volumes?
Hello Arno, Thanks for the pointers. Yup thats' the way I've being doing it; basically writing weof on each tape before labeling. But this is a long step. I've been thinking got to be a better way of doing it. I'm thinking the re-label should be able to help but I'm doing it wrong somehow. The way I arrange it is like this. Volume Pools:- Storage1-- Refers to HP DLT Surestore mounted to /dev/nst0 -- all tapes in volume are given volume names Storage1-01 till Storage1-60 Storage2--Refers to HP DLT Surestore mounted to /dev/nst1 -- all tapes in volume are given volume names Storage2-01 till Storage2-20 I'm looking to move tapes from volume Storage1 to Storage2. But when I relabel lets say tape Storage1-60 to Storage2-21, the relabeling works but it's in the wrong volume. It's still listed in Volume Storage1. Basically the only one with naming convention Storage2-?? in Storage1. Does that make sense? Actually I could probably do the relabeling, maybe just need the command to assign a tape that currently in Volume Storage1 to Storage2. Thanks!

Since I'm using bacula console, I initially thought of doing a delete-volume-Storage1. Then label the tape as a new volume in Storage2. However bacula will mount the tape and detect that it contains a label namely from Storage1. I had already deleted the volume but it's still detecting the volume in the tape. How do I clear the contents for this particular tape so that I can use it as a new volume? You clear the label from the tape by overwriting it, for example using 'mt weof' on it twice. In any case, I think you took the wrong route... It would have been easier to simply move the tape from one autoloader to the other and have it detected with the 'update slots' command. As long as you use identical Media types, that should have been all. If you used different Media Types, you would first adjust tis information in the catalog. Arno Thanks!
