Red Hat Bugzilla – Bug 90809
odd db4 error with 2.5.69-mm4
Last modified: 2007-04-18 12:53:42 EDT
Description of problem:
When rpm is run on redhat 9.0 on linux-2.5.x as root, it hangs, and select()
times out. The problem is related to O_DIRECT, apparently. Here's output from
[root@www root]# rpm -qi iptables
rpmdb: unable to join the environment
error: db4 error(11) from dbenv->open: Resource temporarily unavailable
error: cannot open Packages index using db3 - Resource temporarily unavailable
error: cannot open Packages database in /var/lib/rpm
package iptables is not installed
Version-Release number of selected component (if applicable):
use rpm as root under linux-2.5.x on redhat 9.0
Steps to Reproduce:
Created attachment 91658 [details]
"strace -f -s2048" of the failure case
Created attachment 91659 [details]
"strace -f -s2048" of the success case as normal user
Oh, forgot to mention... The following command allows execution of rpm as root,
as it makes it ignore O_DIRECT..
LD_ASSUME_KERNEL=2.2.5 rpm -qi yadda yadda
I got this info from akpm in lkml, so if you want to search the archives for the
thread, search for the subject "Re: odd db4 error with 2.5.69-mm4 [was Re:
Huraaa for 2.5]"
The following bugs might be clueful:
By the way, what would make 2.5.69-mm4 not NPTL savvy?
Yup. O_DIRECT use by db-4.1.25 is hacked out in (at least)
rpm-4.2-1 (just released), but it's gonna be a mess.
