PrerequisiteAll nodes should be up and ready on the BYNET.
Data disk expansion is not reversible.
- Enable storage expansion.
-
Stop the database.
# tpareset -x -f -y stop system -
Run the following command on all nodes to confirm the database is down.
# pdestate -a
PDE state: DOWN/HARDSTOP -

Expand the system storage (TBs per base node) with any optional arguments.
Data disk expansion is not reversible.
# tdc-expand-storage TBs_per_base_node [options]
where [options] might include -a, -p, or -q. See Optional Arguments for Expanding Storage.
