8.3.5 broken after power fail

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now I'm sure that the following configuration can destroy your database:

* Linux host with XEN, XFS filesystem with "nobarrier", RAID controller 
with battery backed cache.
* XEN vm with XFS filesystem with "nobarrier" with postgresql
* your daughter with 3.5 years switching off the power supply of the 
server
I guess one shouldn't use "nobarrier" on a XEN XFS domU machine.

Now, can somebody help me fixing this error? I did "vacuum analyze 
verbose" and it stopped here:

INFO:  vacuuming "pg_toast.pg_toast_1281127"
ERROR:  could not access status of transaction 2299723776
DETAIL:  Could not open file "pg_clog/0891": No such file or directory.

What can I do?
