I ran the db_recovery tool, and by itself, that didn't fix enough to get the server running.
I was going to make a backup copy of the data directory before trying other things, but during the copy, got a bunch of Input/Output errors. That triggered me to try an FSCK on the EXT3 file system I was mounting. After that fsck (which found many problems), I tried starting the server again, and it came back up. I in the process of seeing if all is there, but it's running now, and files still appear to be in place.

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? -sam On May 27, 2009, at 9:45 AM, David Metheny wrote: I'm getting the following error starting up a PVFS2 server, running both IO and metadata PVFS2: [D] PVFS2 Server version 2.6.2pre1-2009-05-12-185735 starting.

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?
