error ‘Default’ opID=HB-host-8637@82541-3778684f] An unrecoverable problem has occurred, stopping the VMware VirtualCenter service. Error: Error[VdbODBCError] (-1) “ODBC error: (00000) – ” is returned when executing SQL statement
PANIC: checksum mismatch: disk has 0x4addc132, should be 0x7cb3b932
filename base/16385/24461, BlockNum 37, block specifier 1663/16385/24461/0/37
Cause:
The root cause is you likely lost power, but the larger problem is obviously that the VMware vCSA is built using one of the most un-user friendly databases in this galaxy (Postgres). With that said, let’s get this hunk of garbage beautiful piece of modern infrastructure management back online.
Solutions:
Repair vPostgres Indexes:
If you have Index errors in the log file (anything mentioning issues with *idx), you will need to regenerate the particular index in the Postgres database.   To accomplish this:
Repair vPostgres Data:
If you have errors in your logs that complain about invalid checksums, you will need to force Postgres to fix these.  There is no MySQL type command to automatically repair all databases (glorious!). You will need repair each issue manually.  There will likely only be one that is preventing vCenter from fully starting.
Your error message will look like this:
