xapi crash loop

siemsenit

Hi,

after recovering from a power failure, xapi keeps crashing with this obscure error in xensource.log:

Aug 13 11:34:20 hostname xapi: [debug||0 ||xapi] xapi top-level caught exception: INTERNAL_ERROR: [ (Scanf.Scan_failure\x0A  "scanf: bad input at char number 6: looking for ':', found '.'") ]

Does anyone have an idea what causes this situation?

All the best,
Sven

Probably some corruption in your xapi database. Do you have a backup of the pool metadata?

@Danp unfortunately not, at least not externally. And I think restore metadata would be kind of tricky, since the xapi tools won't work, XO is inside a VM and reinstalling xcp-ng would kill the SR on the primary disk.

It's a test/dev system at home anyway and not too important. I'll erase it and make a new one. However, I do now understand the importance of metadata backups better.

Are there any tools to edit state.db?

Found it. Error is related to https://github.com/xapi-project/xen-api/issues/4141

Somehow, the PCIe bus address of the server's ASPEED VGA adapter changed.

I got the new bus address with lspci and edited state.db accordingly. Works now. However, this seems to be a very strange bug.
