[ovirt-devel] Re: [URGENT] - seems like regression: Re: Re: Misc configuration': Failed to start service 'rh-postgresql95-postgresql

Hi, I'm unable to reproduce that issue outside OST, following scenarios worked without any issues: Scenario 1 1. Make sure that selinux-policy-*3.13.1-229.el7_6.9 is not installed 2. Install and configure ovirt-engine 4.2.8 3. Login to webadmin - everything works fine 4. Update to selinux-policy-*3.13.1-229.el7_6.9 5. Login to webadmin - everything works fine 6. Try to restart ovirt-engine and rh-postgresql95-postgresql services 7. Login to webadmin - everything works fine 8. Upgrade all other available packages 9. Login to webadmin - everything works fine 10. Reboot the machine 11. Login to webadmin - everything works fine Senario 2 1. Update CentOS to latest version and make sure that selinux-policy-*3.13.1-229.el7_6.9 is installed 2. Install and configure ovirt-engine 4.2.8 3. Login to webadmin - everything works fine So continuing the investigation, but so far it seems to me related only to OST Martin On Mon, Feb 18, 2019 at 7:39 AM Eitan Raviv <eraviv(a)redhat.com&gt; wrote: > Just to add some coal to the fire, here are my findings for failures of > the 4.2 OST network suite: > > Following the selinux update [0], engine setup fails because what looks > like failure of engine to communicate with postgresql. > In [1]: > > Feb 16 19:26:55 lago-network-suite-4-2-engine systemd: Starting PostgreSQL database server... > Feb 16 19:26:55 lago-network-suite-4-2-engine postgresql-ctl: postgres cannot access the server configuration file "/var/opt/rh/rh-postgresql95/lib/pgsql/data/postgresql.conf": Permission denied > Feb 16 19:26:56 lago-network-suite-4-2-engine postgresql-ctl: pg_ctl: could not start server > Feb 16 19:26:56 lago-network-suite-4-2-engine postgresql-ctl: Examine the log output. > Feb 16 19:26:56 lago-network-suite-4-2-engine systemd: rh-postgresql95-postgresql.service: control process exited, code=exited status=1 > Feb 16 19:26:56 lago-network-suite-4-2-engine systemd: Failed to start PostgreSQL database server. > Feb 16 19:26:56 lago-network-suite-4-2-engine systemd: Unit rh-postgresql95-postgresql.service entered failed state. > Feb 16 19:26:56 lago-network-suite-4-2-engine systemd: rh-postgresql95-postgresql.service failed. > > and in [2] there are selinux access denials for pg_ctl to read the postgres.conf file: > > type=AVC msg=audit(1550363215.978:1067): avc: denied { read } for pid=8648 comm="pg_ctl" name="postgresql.conf" dev="vda4" ino=888710 scontext=system_u:system_r:postgresql_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=file permissive=0 > type=SYSCALL msg=audit(1550363215.978:1067): arch=c000003e syscall=2 success=no exit=-13 a0=7ffe611ff730 a1=0 a2=1b6 a3=24 items=0 ppid=1 pid=8648 auid=4294967295 uid=26 gid=26 euid=26 suid=26 fsuid=26 egid=26 sgid=26 fsgid=26 tty=(none) ses=4294967295 comm="pg_ctl" exe="/opt/rh/rh-postgresql95/root/usr/bin/pg_ctl" subj=system_u:system_r:postgresql_t:s0 key=(null) > type=PROCTITLE msg=audit(1550363215.978:1067): proctitle=2F6F70742F72682F72682D706F737467726573716C39352F726F6F742F7573722F62696E2F70675F63746C007374617274002D44002F7661722F6F70742F72682F72682D706F737467726573716C39352F6C69622F706773716C2F64617461002D73002D77002D7400323730 > type=AVC msg=audit(1550363215.978:1068): avc: denied { getattr } for pid=8648 comm="pg_ctl" path="/var/opt/rh/rh-postgresql95/lib/pgsql/data/PG_VERSION" dev="vda4" ino=888709 scontext=system_u:system_r:postgresql_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=file permissive=0 > type=SYSCALL msg=audit(1550363215.978:1068): arch=c000003e syscall=4 success=no exit=-13 a0=60a640 a1=7ffe611ffa50 a2=7ffe611ffa50 a3=2f62696c2f35396c items=0 ppid=1 pid=8648 auid=4294967295 uid=26 gid=26 euid=26 suid=26 fsuid=26 egid=26 sgid=26 fsgid=26 tty=(none) ses=4294967295 comm="pg_ctl" exe="/opt/rh/rh-postgresql95/root/usr/bin/pg_ctl" subj=system_u:system_r:postgresql_t:s0 key=(null) > type=PROCTITLE msg=audit(1550363215.978:1068): proctitle=2F6F70742F72682F72682D706F737467726573716C39352F726F6F742F7573722F62696E2F70675F63746C007374617274002D44002F7661722F6F70742F72682F72682D706F737467726573716C39352F6C69622F706773716C2F64617461002D73002D77002D7400323730 > type=AVC msg=audit(1550363215.994:1069): avc: denied { getattr } for pid=8654 comm="postgres" path="/var/opt/rh/rh-postgresql95/lib/pgsql/data/postgresql.conf" dev="vda4" ino=888710 scontext=system_u:system_r:postgresql_t:s0 tcontext=unconfined_u:object_r:var_t:s0 tclass=file permissive=0 > type=SYSCALL msg=audit(1550363215.994:1069): arch=c000003e syscall=4 success=no exit=-13 a0=1d862b0 a1=7fff91968710 a2=7fff91968710 a3=2f62696c2f35396c items=0 ppid=8648 pid=8654 auid=4294967295 uid=26 gid=26 euid=26 suid=26 fsuid=26 egid=26 sgid=26 fsgid=26 tty=(none) ses=4294967295 comm="postgres" exe="/opt/rh/rh-postgresql95/root/usr/bin/postgres" subj=system_u:system_r:postgresql_t:s0 key=(null) > > whereas in [3] - the build just before the selinux package update, these errors did not occur. > > Looks like alongside enabling selinux a policy update is required. > > thanks > > > [0] https://jenkins.ovirt.org/job/ovirt-system-tests_network-suite-4.2/900/ > [1] https://jenkins.ovirt.org/job/ovirt-system-tests_network-suite-4.2/901/ar... > [2] https://jenkins.ovirt.org/job/ovirt-system-tests_network-suite-4.2/901/ar... > [3] https://jenkins.ovirt.org/job/ovirt-system-tests_network-suite-4.2/899/ar... > > > On Sun, Feb 17, 2019 at 11:16 PM Dafna Ron <dron(a)redhat.com&gt;
