[gpfsug-discuss] Encryption - guidelines, performance penalties?

[Simon Thompson (Research Computing - IT Services)]

The docs
(https://www.ibm.com/support/knowledgecenter/#!/SSFKCN_4.1.0/com.ibm.cluster.gpfs.v4r1.gpfs200.doc/bl1adv_encryption.htm)

Do say at rest.

It also says it protects against an untrusted node in multi cluster.

I thought if you were root on such a box, whilst you cant read the file, you could delete it? Can we clear that up?
