BDoS feature (AFM/DHD) needs to share learned traffic characteristics across nodes (within a cluster) and across devices (within the device group). Previous infrastructure used by BDOS could cause spikes in disk usage due to a large number of snapshot files being saved under /config/filestore/ partition (.trash_bin_d and files_d/Common_d/l4bdos_context_d sub-directories).
The /config partition on the BIG-IP system consistently fills up with large numbers of directories/files under /config/filestore/, eventually causing system to run out of disk space under /config partition.
BDOS feature is enabled on at least 1 context (either at global context or at least 1 virtual server).
As a workaround, manually delete files/directories filling up under /config/filestore/ partition (.trash_bin_d and files_d/Common_d/l4bdos_context_d sub-directories) to free up disk space.
BDOS now uses a new (and improved) infrastructure for sharing data across nodes/devices (within device group/cluster setup) that does not require snapshot files to be maintained under /config/filestore/ partition.
