[sos-devel] [RFC PATCH] sosreport: Check for rpm database corruption during initialization

[Aruna Balakrishnaiah]

sosreport runs an rpm query to get the package list. If rpmdb is corrupted
sosreport hangs for ever hence check for rpmdb consistency before running
the rpm query.

When rpmdb is corrupted rpm commands hangs forever,
yum check will result in:

yum check
error: rpmdb: BDB0113 Thread/process 43828/70366497037824 failed: BDB1507 Thread died in Berkeley DB library
error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db5 -  (-30973)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Error: rpmdb open failed

So look for 'rpmdb open failed', include this check in redhat policy as
yum command is specific to redhat.

Bryn,
	Please suggest if there is a better way to do it.

Regards,
Aruna
