Hi Team,
We tried to upgrade mysqld-exporter image running in percona xtradb mysql cluster through helm , but after upgrade database is lost , new persistent volume is created.
Is there any way to recover deleted persistent volume or let us know what is the best way to perform upgrade through helm
Here is helm file below
haproxy:
nodeSelector:
env: percona-review
tolerations:
- key: “percona”
operator: “Equal”
value: “review”
effect: “NoExecute”
pxc:
tolerations:
- key: “percona”

nodeSelector:

persistence:
enabled: true
storageClass: “fast-review”
accessMode: ReadWriteOnce
