enable-high-availability

Info

MemSQL Helios does not support this command.

Run memsqlctl enable-high-availability on the host containing the Master Aggregator.

Usage

This will automatically update the 'redundancy_level' of the master aggregator
from 1 to 2, and evenly assign leaves to availability groups 1 and 2 (by
removing and re-adding them).

  -h, --help                  help for enable-high-availability
  -p, --password STRING       the SQL password for re-adding the leaves (deprecated on clusters running MemSQL 7.0.6 or later)
      --skip-colocate-check   do not check whether colocation of a leaf pair is necessary
      --skip-disk-check       do not check that each leaf node has at least half of its disk space free
      --user string           the SQL user for re-adding the leaves (deprecated on clusters running MemSQL 7.0.6 or later)

  -v, --verbosity count                     Increase logging verbosity: valid values are 1, 2, 3. Usage -v=count or --verbosity=count
  -y, --yes                                 Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default

This command is interactive unless you use either the --yes or --json flags to override interactive behavior.
