thanks for fast response! No we doesn't use fips.

ok the response you posted indicated that the drive has the capability but the application (PBS) is prevented from changing the encryption parameters.

maybe there is another separate setting to allow application controlled encryption in your library?

library haven't this settings and i disabled encryption on pbs.

ok maybe this is the problem, from what i can see, you have to set it to 'Application Managed Encryption (AME)' for it to work with pbs. PBS assumes it can set the encryption parameters and will fail currently if it cannot do that (even if it is just setting the drive to unencrypted). The application managed encryption setting should pbs allow to do that.

Dominik, big thank's!

Hi, @dcsapak! Why when i doit barecode labaling i often get error after each cartridge:


2025-04-15T07:37:19+03:00: checking/loading media '000008L9'
2025-04-15T07:37:56+03:00: Label media '000008L9' for pool 'VMs_pool'

i see that this is an lto9 drive. Usually when a LTO9 tape is loaded the first time into a drive, it gets initialized (which can take up to two hours) and during that time it and the drive is unavailable. Usually, libraries have some 'bulk initialization' feature where you can do that for all tapes in the library automatically

we have code to wait for that on tape format, but it seems when doing a barcode labeling, we don't

as a workaround, you should use the libraries initialization feature, but i'll see if i can fix that in our code too

Waiting you fix code only. Often get error. Long timeout.... If i insert cartridge > Label media > set pool > ok

for your info: i sent a patch to increase the timeout if we detect calibrating:
https://lore.proxmox.com/pbs-devel/20250415114043.2389789-1-d.csapak@proxmox.com/

but it could be a while before this lands in any repository, so for now it's still recommended to initialize beforehand with your library directly

@dcsapak hi! Why when doing backup i cant use tape? PBS can working with one task in system only?

@dcsapak hi! PBS updated to 3.4.1 and now working timeout 2h5m.


Can you add manual change this timeout in web interface? Very long. In my tape library calibration 10-15min.
