Deleted packs keep their RBD extents allocated on the backing store until the guest discards them. Run a best-effort fstrim on the mirror mount after sync and before unmount, only when the run will commit and only when the host enabled it: the VM agent returns GetStickyDiskResponse.fstrim_timeout_secs (fa live config guest_fstrim_timeout_secs), saved in action state at mount time; 0 means no trim. Any failure or timeout only logs. Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>
…oto package predates it The bundled GetStickyDiskResponse has no fstrim_timeout_secs yet, and protobuf-es keeps fields it does not know in the message's unknown-field list (the gRPC transport is binary), so decode field 8 from there when the typed field is absent. Releases built before the field existed therefore honour the host budget once the agent sends it. Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

I'll fix CI failures and address comments from users with write access. I'll skip comments containing "(aside)".

Bump @buf/blacksmith_vm-agent.bufbuild_es to a build that includes GetStickyDiskResponse.fstrim_timeout_secs (fa #6600) and drop the unknown-field-8 decoding. Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

GetStickyDiskResponse.fstrim_min_extent_bytes (fa #6823) is saved as action state next to the timeout budget and, when positive, becomes `fstrim -m <bytes>` so free extents below the host's threshold are not discarded. Zero or absent leaves fstrim at its default. Bumps the @buf vm-agent packages to the fa main build that carries field 9 and regenerates their licensed records.

In git-mirror cleanup, run
fstrimon the mirror sticky disk before it is unmounted and committed, so freed blocks are discarded from the backing image.GetStickyDiskResponse.fstrim_timeout_secs(field 8). Mount reads it (from the typed field, or from unknown field 8 when the bundled proto package predates it) and stores it in action state;0/absent disables the trim.shouldCommit), after sync/maintenance and beforeumount.timeout <budget> sudo fstrim -v; any exit code or exception only logs and never fails the step.Start here:
