Hi,
Well your error is quite clear. The statistics server won't start because the data volume is not found:
" try to open existing persistence data volume, but filesystem path does not exists: /hana/zedbdi/data/HA1/mnt00001/hdb00006/"
What happened with that folder?
If you need to reinitialize the stats server follow SAP Note 1950221.
