Error: "no usable media found" during tape backup

mat5911 · Feb 17, 2023

Hello,

I'm testing PBS with a LTO4 drive to backup VMs to tape. Writing to tape works as expected. I created 5 Mediapools each with one tape for Mon - Fri backups. Retention policy is set to "overwrite", allocation policy to the respective day. E. g. the monday pool is set to "mon". Then I created backup jobs for the respective day.
The backup starts as configured but during the backup I get the error
TASK ERROR: alloc writable media in pool 'MP_Donnerstag' failed: no usable media found
At this time, there are already 437631MB written to the tape (summarized the "wrote ... chunks log entries). LTO4 has a capacity of 800GB uncompressed. So there should be enough space to write.

These are the last lines of the backup task log:

Syslog shows:


Feb 16 18:01:23 pve02 proxmox-backup-proxy[3338263]: no empty media in pool, try to reuse expired media
Feb 16 18:01:23 pve02 proxmox-backup-proxy[3338263]: no empty or expired media in pool, try to find unassigned/free media

PBS version is 2.3.3.
Is there a way to see if it is a capacity problem?

dcsapak · Feb 17, 2023

ok, i mean there is some overhead (the snapshots, metadata per chunk etc) but i guess that should not be that much.
though it seems that pbs simply thinks the tape is full and want to write to the next tape

can you post the output of

Code:

proxmox-tape status --drive YOUR_DRIVE_NAME
proxmox-tape volume-statistics  --drive YOUR_DRIVE_NAME

while the tape is inserted?

Hi,
sorry for the delay. Here are the outputs

# proxmox-tape volume-statistics  --drive LTO1
Error: read tape volume statistics failed - Illegal Request, Additional sense: Invalid field in cdb

dcsapak · Feb 27, 2023

mhmm... i checked the code and the only point where we request a new tape is when the drive reports the 'End of Medium' flag, which indicates that the tape is running out of space...
i'll see if i can find out more, but note that lto4 is only support in a best-effort way, and >= LTO5 are recommended/supported.

mat5911 · Feb 27, 2023

Yes, the drive is really outdated

I think we should buy a current one.
Thank you for your support.
