Since we have so many machines getting corrupted a rpmdb because of the stat on hung nfs mounts problem we frequently have to rebuild the rpmdb.
after running:
# rm -f /var/lib/rpm/__db*
# rpm -vv --rebuilddb
# rpm -qa
there are no __db files in /var/lib/rpm/ and when we check for stale locks we get an error.
# /usr/lib/rpm/rpmdb_stat -c -h /var/lib/rpm
db_stat: DB_ENV->open: /var/lib/rpm: No such file or directory
However, rpm -qa and other operations seem to work fine.
strace'ing the rpm -qa shows that it doesn't see the files or recreate them.
access("/var/lib/rpm/__db.001", F_OK) = -1 ENOENT (No such file or directory)
stat64("/var/lib/rpm/__db.002", 0xbfffe540) = -1 ENOENT (No such file or directory)
stat64("/var/lib/rpm/__db.003", 0xbfffe5a0) = -1 ENOENT (No such file or directory)
access("/var/lib/rpm/__db.001", F_OK) = -1 ENOENT (No such file or directory)
Doing a find on the whole file system doesn't turn up any other __db files either. I'm a bit puzzled about how this is working at all.
I've opened a support case with RedHat but was wondering if any of you had seen this problem before.
