...an existing shell script that we use for copying files from disk to tape via tar, one file at a time. (Don't ask why. It's a legacy script. Long story.) We're tweaking this script to use --o_direct when tarring the file to tape and that seems to be working fine: # tape device is /dev/nst0 $ tar --o_direct -cvf /dev/nst0 /ocfs/RMAN_test_file ./RMAN_test_file But, to pull that same file back off tape and save it to the original OCFS location, it seems that we cannot use --o_direct: # skipping commands to reset the tape pointer to the proper location $ tar --o_direct -xvf /dev/nst...

...n/dump -0v -z2 -f /media/usb_drive/dump0 /home I played with restore on that, and it tested fine. For the tape, I thought it would be nice to add /var/log (should have done it before, but didn't think of it...) Trying to adapt the knowledge to a tape library... /sbin/dump -0 -v -z2 -f /dev/nst0 /var/log /sbin/dump -0u -v -z2 -f /dev/nst0 /home I have a cron job that dumps the results to /var/log/dump.log, and a review of the log file claims all went well. Now for the restore... I just tried playing with different options of restore, but could not successfully restore anything. I en...

Hi, I have a CentOS 4.1 (with a two hdds RAID 1 using mdadm) running some database system.... I connected a DLT device on its SCSI interface (/dev/nst0) in order to make some external backup..... I dump several filesystems (/, /boot /usr /var /home and others)....so and when I try to dump manualy for expmple /boot I get this: [root at Server ~]# dump -0vuf /dev/nst0 /boot DUMP: Date of this level 0 dump: Thu Sep 13 16:00:02 2007 DUMP: Dumping...

...worker jbconfig command. The jbconfig command detects the Qualstar, and then detects /dev/sg3 as the tape device. Now Networker can use this device to move tapes around in the robot, but not to read and write. So I have to delete / dev/sg3 from the Networker configuration, and then add /dev/nst0. And then it works (for a while). So I'm wondering, why the software is setting me up with /dev/sg3 instead of /dev/nst0; and is there anything I can do about it. Bonus question if anyone else had a similar issue. Thanks, Tony Schreiner Boston College

Hi all, We have a bit of a problem with backups. We've been using bacula to tape and now trying to disk but it's a complete nightmare as regards tape management. The backup to file storage went ok for ages and now is stuck 'waiting for max storage jobs' which is odd as that's set to 20 and it's the only backup running. That's totally typical of bacula. Can anyone

Greetings, Does anyone know if it is possible to give a guest domain access to character device hardware such as a SCSI tape drive (/dev/st0 | /dev/nst0)? I have recompiled the guest xenU kernel with hardware access and declared the pci SCSI card in the config file directive as follows: pci = [ ''4,3,0'' ] The log file when started reports: [2005-11-01 17:24:57 xend] DEBUG (XendDomainInfo:1178) Creating pci device dom=7 bus=4...

I created a cron job to invoke a dump script according to Tower Of Hanoi. I am dumping a subdirectory and a filesystem. The backup script, with some other lines removed: /path/to/dump -0 -fv /dev/nst0 /var/log /path/to-dump -3 -fv /dev/nst0 /home When viewing the dump logs, it looks like it is taking the whole job as a level 0. Am missing something? Thanks. Scott

Posting here in the hope that some one may have encountered problems with recovery from backups on LTO4 media and found a solution. Back ups on FujiFilm LTO4 media (800/1600). Archives created using tar -cf /dev/nst0. ?The tapes were fine when the archives were created (tested by extracting random sample files from them) but something went wrong in storage (no physical damage). Now a few LTO4 tapes are giving I/O errors when I try to extract data from them. ? Tried dd_rescue and that too fails giving ?I/O erro...

I have an Overland tape library connected, via SCSI card, to an out-of-box, full install of C5 install on an old PC. I have a script that uses tar to archive data to tape and mtx to change tapes. What I don't know, if possible, is to obtain the status of how much tape is left in the drive. If I get a write failure, I'd like to know if the tape is bad or has run out of space. I

I posted this in the Bacula list without success so I hope I might have some luck here. Btape and mt can access my DDS-3 Seagate Archive Python 06480-xxx tape drive but Bacula tray-mon ends up finally stating that it cannot open device /dev/nst0? That is the device string that I use to access the drive, oddly enough it also suggest the SD could not open the one file based storage location I have either, yet I can Label new media and I see it appears in the directory? I installed from RPM's. Anyone got any ideas or pointers they could...

So I thought I'd get a head start for next week - I have a low-power Linux box that has a few samba shares mounted, and limited hard disk space. This box is connected to a tape library via SCSI card. I want to find the best way to create a full, then incremental backup of the samba mounts, directly to tape. Some of the samba mounts are appliances that cannot run any special

Hi, i got an SCSI-Controller with a tapeloader and a external raid attached. exporting the raid-set is no problem via disk... now i have to export the devices for the tape-backup to one of my domUs. Devices needed are /dev/sg1 (for the loader) and /dev/nst0 (for the drive). I could not find any helpfull documentation to this. Could anyone give me a hint? thx in advance max -- --------------------------------------------------------------------------- Max Bidlingmaier Tel: +49-3677-465084 _______________________________________________ Xe...

How does one serve out a tape drive attached to a Unix server similar to serving out a printer attached to the server? Tape drive is a TRAVAN-5 20/10GB at /dev/nst0 (nonrewinding scsi) and responds to "mt" commands appropriately. thanks -- tom | "When we are born we cry that we have tommyr@agora.rdrop.com | come to this great stage of fools!" | W.

Hello CentOS list, I have a requirement that I need to use encryption technology to encrypt very large tar file on a daily basis. The tar file is over 250G size and those are data backup. Every night the server generated a 250G data backup and it?s tar?ed into one tarball file. I want to encrypt this big tarball file. So far I have tried two technologies with no success. 1) generating RSA 2048

I need to install an HP Surestore dlt on a Centos 4 machine and I am at a loss as to how to proceed. Can someone either provide or point me to an online reference on how to proceed to add and configure a SCSI adapter and tape drive. I have read, but not really understood, the man page entry for st. Does kudzu handle this? Regards, Jim I am a digest subscriber so the favour of an
