yes, thank you, someone else commented that earlier. A bit unintuitive to have multiple special device nodes per device that changes the minor behavior like this though.
actually I think I capture that, but I'm currently somewhat overworked and out of time, and I guess I lost it in final editing, ... :-/ I have another DAT video on the schedule, I can include it there ;-)
Hey! LTO tapes and tar are still the backbones of my archival and backup strategy. You cant beat the shelf life and price per capacity but a drive costs almost 3000 bucks which is the downside. And oh boy, dont get me started on type libraries and automation those things are very cool ;D
I just picked up my first LTO drive for use as my deep archive. Its an LTO4. Funnily enough, just after buying it off ebay, I stumbled across an unwanted LTO5 drive at work. Now I have both :D
I remember the first place I worked at used DDS2 tapes for their backups. I never got involved in it because the IT manager made out like it was a very complicated technology. Interesting to see how rudimentary it actually was some twenty years later.
You are using /dev/st0 which auto rewinds, use /dev/nst0 to stop that. There are several devices created for a tape drive, each enables or disables a certain option if you use that device. Basically those that start with an 'n' like /dev/nst0 will not auto rewind.
yeah, thanks, someone else pointed that out alaready down below. Quite a strange exception in "'Un*x" that there is more than one device node with special quirks per device. IMHO this should never have been done like this, and instead thru seek or other ioctls on one device node only, ... sigh.
@@renerebe Ah I did look to see if anyone mentioned it but I guess I missed it lol I also prefer the device name method of controlling the devices options. I'm pretty into the idea of everything is a file so think avoiding system calls as much as possible is best. Really everything should be files and controlled with text. Plan 9 is an operating system I would love to be in. Everything is a file there, even your GUI and network :)
Thank you - i had an octane :) but a linux kernel was failing ("H.E.A.R.T. Attack" - really ) as it had 2 cpu's and two enabled - thankfully you could disable one of them at bootup shell and later it worked as yours :) - none the way Mr. Skowronek (SGI/Mips kernel hacker) made a good job so we can now see your video ! :)
RIP SGI their biggest mistake was leaving MIPS and jumping into Itanium.....even HP fell for it and killed HP-Risc only for Intel to make x86 cpus that would make Itanium redundant.
Aaaah yes, blocksize. I once shot myself in the foot by using some random huge blocksize (like 1048576) that I didnt write down and wondering a few years later when I needed the backup why that damn tape is not readable....
Nice ! I heard there was a SGI tape slider (optional) for the Octane. Is this exactly the same one as for the 3.5"-inch UW-SCSI drive sleds ? The part number is different for these, I think !
the memories.... HP servers from the 90's :) The keyboard sound feels pretty good. I think you mentioned on a previous video the model. Can anyone please mention the model ? Need something to "spare" my MBP butterfly fragile kbd :/ Using the 2009 compact Apple kbd, still love it, but want a new one "for the road". thank you :)
Hi, the keyboard is a Filco Majestouch: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XZtwmZQo-Z0.html, that I mostly got for the PS2 compatibility for the Octane and such, even cooler, but way more expensive is the Tex Yota II I DIY Kit assembled recently: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3ojdjQovNOQ.html
