23:17:13,xen01,LINSTOR/Controller,Resource Created: linstor-csi provisions a short-lived volume: pvc-395da199-d455-4004-ac0d-f6c6016ebf4e.
23:17:16,xen01,kernel (drbd),Sync Begins: xen01 connects to xen05 as a SyncSource and begins synchronizing the volume to it.
23:17:49,xen01,LINSTOR/Controller,Teardown Requested: The CSI plugin changes its mind or finishes its task, requesting sequential deletion (DelRsc) of the volume replicas across the cluster.
23:17:51,xen01,LINSTOR/Controller,Source Disk Removed: Linstor removes the volume from xen01 itself (Toggle Disk ... removing disk).
23:17:52,xen01,kernel (drbd),Source Goes Diskless: xen01 detaches the underlying storage block (UpToDate -> Detaching -> Diskless). It alerts peers it can no longer satisfy read requests, calling drbd_bm_resize with capacity == 0.
23:17:53,xen05,LINSTOR/Satellite, While the cluster connection is actively tearing down, xen05's local background DeviceManager wakes up and detects the volume. It attempts an online re-alignment to round up the block layer size to match the 4MiB extent rule (26220040 KiB to 26222592 KiB).
23:17:54,xen05,kernel (drbd),Fatal Crash: xen05's DRBD driver tries to resize and count its synchronization bitmap block pointers. Because its peer source (xen01) dropped to zero capacity mid-flight, DRBD hits memory corruption. It triggers a General Protection Fault at drbd_bm_count_bits+0x223/0x300 and panics the kernel.
