Sadanand Shenoy updated HDDS-10984:
-----------------------------------
Description:
Although not a common scenario, I recently encountered an issue where the user
accidentally deleted the SCM certs from the local certs directory for all SCMs.
On restart, the primordial node self signs a new cert and starts up however
the non-primordial members in the HA ring, request a CSR to the primordial
node. This request doesn't go through as it requires a quorum i.e ratis needs
to be initialized . however in order for ratis to be initialised, it needs to
verify certs. This leads to a dead-lock like situation.
Ratis is needed for CSR (getCert) request as it persists the signed Cub ca cert
in its rocksdb.
Like I mentioned in the beginning, this is not a common case but since we
already persist certs in the SCM rocksdb, a tool to restore certs should be
helpful in this case.
