Input/Output error with any operation on tape

[WORMSTweaker]

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

Some verbose logs taken from STFS output:

Hi! Any chance you might be running into #1 ?

[WORMSTweaker]

Oh whoops! That was indeed it! I didn't connect the dots and think that those 2 issues could be related, but indeed setting stsetoptions scsi2logical allows everything to work properly, initialization ftp and file writing

Very sorry about this (easily resolvable) open issue!
