To unpack previously packed, or containerized, files, in this case from the ‘dicom’ filepool policy, run the following command from the OneFS CLI:
# isi filepool policies modify dicom -–enable-packing=false
Ensure there is sufficient free space on the cluster before unpacking. Also, if the data is in a snapshot, it will not be packed – only HEAD file data will be containerized.
A threshold is provided, which prevents recently modified files from being containerized. The default value for this is 24 hours, but this can be reconfigured using the isi_packing –min-age <seconds> command, if wanted. This threshold guards against accidental misconfiguration within a filepool policy, which could potentially lead to containerization of files which are actively being modified, which could result in container fragmentation.
