The linstor-Satellite pod stdout log references its error reports
only by ID:
[DeviceManager] ERROR LINSTOR/Satellite/... SYSTEM - Failed to
create zfsvolume [Report number 6A4A394E-E4EA0-000000]
The body of that report (which carries the actual `zfs create -V …`
stderr, the DRBD adjust output, the storage-driver stack trace, and
the exit code) lives at `/var/log/linstor-satellite/ErrorReport-*.log`
on the satellite pod. crust-gather only captures pod stdout, so the
report body stays on the pod's ephemeral filesystem and is lost when
the e2e sandbox is torn down at end-of-job.
Consequence for post-mortem: a run that failed on a
`ResourceExhausted` / `Not enough available nodes` CreateVolume retry
loop shows only the driver-level symptom in cozyreport. Root cause
attribution (out-of-space, dataset name conflict, ZFS module error,
kernel signal) is not distinguishable without the report body, and
without the sandbox is unrecoverable.
Extend the linstor module in `hack/cozyreport.sh` to tar the
`ErrorReport-*.log` set off every `linstor-satellite` pod into
`linstor/error-reports/<node>.tgz`. Guarded so a satellite with zero
reports (the healthy case) leaves nothing in the tree, and a
transient exec / tar failure never fails the surrounding cozyreport
run.
Verified against a live dev cluster: label selector
`app.kubernetes.io/component=linstor-satellite` matches all three
satellite pods, and the tar bundle for one active satellite comes
out at ~60 KiB. No product-side change.
