pojntfx / stfs Goto Github PK

Hello, firstly amazing bit of software.

But it really needs a wiki be established with dedicated guidance/scripting for each oprating system, then the readme can just provide usage overview and 1-2-3 example usage workflows that are 100% universal.

I am currently a little lost as a LTO5 LTFS user on windows with both HP and IBM SAS drives as a local user and plan to deploy fibre HBA LTO6 drives with a windows server 2016 system.

As LTFS is a mess on Ubuntu based distros I really am intrested in deploying STFS cross platform and intergrating it into the standard archival workflow guides for vhs-decode.

This is a really great program. I'm busy getting familiar with it, but I really appreciate the thoughtful UI: serving the tape over FTP server is actually extremely handy for me because I need to back up files from a different machine to the one the tape drive is attached to.

On my drive, however, stfs operation initialize or stfs operation archive panics with input/output error. I traced this down to the fact that seek/tell do not work on the drive (even using the mt command from mt-st package) until I run sudo mt -f /dev/nst0 stsetoptions scsi2logical. This seems to persist until the machine reboots.

Did you hit this at all? I can try adding in the syscall to set this parameter as part of MagneticTapeIO methods? Based on strace, all the mt command boils down to is an MTIOCTOP ioctl. And the flag seems to be defined here so I could probably work out what the full ioctl needs to be.

But I figured I'd ask, because you are likely a lot more familiar with how to do ioctls to tape drives than I am.

Hello!

I found STFS randomly, and I've been interested to try ever since discovering it! It's some really nice stuff, but that's not what I'm here to talk about

After installing STFS via the script, I wanted to try it out on my tape drive, only to be met with a very enigmatic "Input/Output error", while trying to server an FTP server. I thought that maybe my tape needed to be initialized, so I tried to do a stfs operation initialize, but it results in the same cryptic I/O error...

What could be the issue here? And thank you in advance for your help!

A few spec details:
OS: Arch, x86_64, Linux kernel 6.6.30-2-lts
SAS controller: Broadcom / LSI SAS2008 PCI-Express Fusion-MPT SAS-2
Tape Drive: HP Ultrium 3280 LTO5 External Drive
Command: stfs serve ftp -d /dev/st0 -m ~/Tape/metadata/metadata.sqlite --cache-write-type memory --compression brotli --compression-level 9 -v 4
