Backup fails between Vertica upgrade steps
Here is my scenario.
My plan was to upgrade Vertica database from version 10.0 to 12.0
OS is Debian Linux if this matters.
According to documentation this should be done through upgrade path taking backups between each upgrade.
1. Upgrade from 10.0 to 10.1
2. Full backup
3. Upgrade from 10.1 to 11.0
4. Full backup
5. Upgrade from 11.0 to 11.1
6. Full backup
7. Upgrade from 11.1 to 12.0
Steps 1-3 were successful but taking backup after Vertica was upgraded to version 11.0 (step 4) failed
with error "Mismatching digests.... Database may be corrupted."
But it seems that database runs just fine, no errors in database log but I can't take backup.
What should I do?
Skip this backup, upgrade from 11.0 to 11.1 and hopefully backup then succeeds?
Or is there some tricks I could try to get backup working?
Searched this forum and google, but did not find anything.
backup command was
/opt/vertica/bin/vbr -t backup -c backup_full.ini --debug 3
Backup config file and vbr log screenshots are attached.
