Previously when the ``ironic-python-agent`` would undergo erasure of block
|
|
devices during cleaning, it would automatically attempt to erase the
|
|
contents of any "Shared Device" clustered filesystems which may be in use
|
|
by distinct multiple machines over a storage fabric. In particular
|
|
IBM GPFS, Red Hat Global File System 2, and VmWare Virtual Machine File
|
|
System (VMFS), are now identified and cleaning is halted. This is important
|
|
because should an active cluster be using the this disk, cleaning could
|
|
potentially cause the cluster to go down forcing restoration from backups.
|
|
Ideally, infrastructure operators should check their environment's storage
|
|
configuration and un-map any clustered filesystems from being visible to
|
|
Ironic nodes, unless explicitly needed and expected. Please see the
|
|
Ironic-Python-Agent troubleshooting documentation for more information.
|
|
issues:
|
|
- |
|
|
Logic to guard VMFS filesystems from being destroyed *may* not recognize
|
|
VMFS extents. Operators with examples of partitioning for extent usage
|
|
are encouraged to contact the Ironic community.
