We have a cloud node instance where the service cannot start and there is a d4 error message in the log file. This suggests that the database has been damaged and needs to be recreated.

What is the procedure to resolve this?

Hello Sanjay,
Thank you for your enquiry. Have you tried exporting and importing back the same database? This usually works and in case it doesn't then I would suggest you to try importing latest backup.

Best Regards,

If a CN database is damaged, then an export/import can be done (only for advanced users who can recognize such issue)

Stop CN service

Go to CN directory and perform normal export/import
Start CN service



Manual steps to recover if D4 and backup can not be created

hansa-cloudnode --rawdata
ren HANSA.HDB HANSA.HDB.D4
hansa-cloudnode rawdata.txt
hansa-cloudnode --backup
ren HANSA.HDB HANSA.HDB.BAK
hansa-cloudnode Backup\TB.TXT
