[Pvfs2-developers] PVFS2 Error on startup

[David Metheny]

We've got db4-4.2.52-7.3.el4 installed.

 

The value of ret after the line 650 call is '-30988'.

That's not a very useful error, but it looks like there might be something
wrong with your dspace db.  Can you run it in gdb, set a breakpoint at
dbpf-dspace.c:650, step to the next line and print the result of "ret"?
Line 650 should have:

b dbpf-dspace.c:

 ret = dbc_p->c_get(dbc_p, &key, &data, DB_MULTIPLE_KEY|DB_NEXT);

 

The ret value is getting translated to a trove error code, except the BDB
error value isn't one that trove recognizes, so it just spits out an error
code that says it doesn't know anything about the error code.

 

What version of berkeley DB are you using?

The server is configured to sync both metadata and data. The server's
connected storage experienced a connection problem, causing a 'read-only
file system' error. After stopping and starting the server, it throws the
above errors each time.

 

I'm using the base 2.6 release, with many patches applied. Any ideas on how
to debug this, or recover from it?

 

Thanks,
