Costel,
If si_rmimage can't find the /var/lib/systemimager/images/centos6 image it
seems that it was physically removed, but if this image was manually deleted
some infos may still be present in oscar database: to check:
mysql -u root oscar
select * from Images;
^D
If you want to remove some entries like centos6 image infos:
DELETE FROM Images WHERE name="centos6";
Then if some nodes are affected to this image (note the id before deleting it).
Let say that centos6 image id was equal to 7 and that centos63 imageid is equal
to 8), then to update your nodes definitions:
UPDATE Nodes SET image_id=8 WHERE image_id=7;
Though, this is hardcore ;-) and not recommanded.
IMHO, my recomendation would be to restart from scratch using: oscar-config -t
I think that this will remove some problems with post-scripts that failed and
left incomplete setups. (like missinc /etc/c3.conf)
oscar-config -t will remove the oscar database, the images (hopefully) and some
oscar packages.
Check that /etc/c3.conf is cleared as well and that
/var/lib/systemimager/images/<your images> are removed.
check that "mysql -u root oscar" fails or do a mysql -u root followed by a drop
database oscar;
Then after having the correct /etc/oscar/supported_distros.txt (with your local
epel) start over with the oscar bootstrapping process and distro setup. I think
that you should experience far less problems.
Though, there are still some problems. Especially in sync_files that for some
unknown reasons is called before nodes are up without the --image-only option
resulting in the /etc/c3.conf containing all nodes as dead.
My advise: before step 7, check if /etc/c3.conf is present and if yes, look at
dead nodes and reenable them is they are tagged as dead.
I'm really sorry, I traked this sync_file bug along the day without success so
far.... I've just discovered that c3_conf_mgr which should handle
disable/enable for nodes does nothing. Even the help seems wrong: --delnodes
whil script looks for --rmnodes options.... Still digging by adding debug
messages that are triggered if $verbose is on.
Best regards.

Olivier,
When trying
si_rmimage centos6
I got
“Couldn't open /var/lib/systemimager/images/centos6/etc/systemimager/boot/ARCH
for reading No such file or directory at /usr/sbin/si_rmimage line 151.”
ls /etc/c3.conf
ls: cannot access /etc/c3.conf: No such file or directory
But does the /etc/c3.conf exists at this step?
In fact, adding nodes failed few days ago so I believe OSCAR did not succeed to
do more than adding them to /etc/hosts.
However, at one moment in time I succeeded to build an image so I will try the
same image name.
I afterthat wrote it again and again many times without succeeding so maybe the
error message above is not a real issue.
I created the local repo and I will try to build the image again.
Thank you,
Costel SEITAN

Hello,
Did you removed the old image? If it is still here (in the oda database at
list), it's normal that sync_files will try to find the old image. Try to do
si_rmimage centos6
BTW, can you tell me if your /etc/c3.conf file has dead nodes (except
remove_for_0-indexing which is normal)
I found a problem: OSCAR::NodeMgt::update_list_alive_nodes is called somewhere
before nodes are up and alive.... resulting in all nodes marked as dead in
/etc/c3.conf resulting in sync_files not syncing anything resulting in oscartst
failing the ssh test..........domino effect.
This routine is called from sync_files, thus I think that sync_files is called
before nodes exists (without --image-only) which confirms your previous error.
This confirm that fixing one for all sync_files will clear many problems (image
failure erroneous messages, c3.conf with dead nodes, files not synced, ....)
Best regards,
Olivier.

Hello,
Thank you for your comments Olivier.
The nodes should not exist, however I see that the entries were added to
/etc/hosts because of my previous tries:
..
# OSCAR block: OSCAR hosts
192.168.0.86 epsl86
192.168.0.87 epsl87
192.168.0.88 epsl88
192.168.0.89 epsl89
But, what made me think of rsyncd was the message
“rsync: failed to connect to 127.0.0.1: Connection refused (111)”
There is something else that I noticed right now. For the last try I decided
to name the SIS image “centos63” (compared to “centos6” just before).
When analyzing the error messages it looks like some of the commands point to
the old image directory (centos6) :
ERROR: Impossible to detect the OS for /var/lib/systemimager/images/centos6 at
/opt/sync_files/bin/sync_files line 319
main::distro_detect('dir', '/var/lib/systemimager/images/centos6')
called at /opt/sync_files/bin/sync_files line 798
ERROR: Impossible to detect the distro (/var/lib/systemimager/images/centos6)
at /opt/sync_files/bin/sync_files line 800.
ERROR: Impossible to execute /opt/sync_files/bin/sync_files -i centos63 --force
--image-only at /var/lib/oscar/packages/sis/api-post-image line 205.
I will create the local epel repo and try again. There is no reason to do so
but I will eventually name my SIS image “centos6” again.
Kind Regards,
Costel SEITAN
