Error: disk usage exceeded flood-stage watermark, index has read-only-allow-delete block

[leandrojmp (Leandro Pereira)]

You are running version 7.17, this setting only exists from version 8.6.

For version 7.17 you need to follow this documentation.

Try to increase the size of watermark, if this does not solve you will need to keep delete indices until there is enough free space.
