lava -- user is deleted - HPC Community - High Performance Computing (HPC) Community

_fmms_ · #1 (**permalink**) October 10th, 2008, 02:09 PM

I am using a recent kusu release:

Code:

[root@master ~]# cat /etc/kusu-release
Kusu "Kramat" 0.10 (build 3520)

But I recognized that the lavaadmin user which was added by the lava kit gets deleted on reboot on my system.

I added a user myself to /etc/passwd with useradd and it got deleted too...

Did I somehow mess up my setup or is this a bug?

Does the cfm tool rewrite the passwd file? Nevertheless lava should no where to add lavaadmin

Hi,

This may be a bug with cfm. Please help us file a bug[1] and we can look into this.

We have tested a normal useradd, followed by a reboot. The user account was not deleted.

I do not understand yet how this is supposed to work. and my /etc/passwd get overwritten on every boot.

I have the following:

Code:

lrwxrwxrwx 1 root root 11 Oct  8 15:34 /etc/cfm/compute-centos-5-x86_64/etc/passwd -> /etc/passwd
lrwxrwxrwx 1 root root 11 Oct  8 15:34 /etc/cfm/compute-diskless-centos-5-x86_64/etc/passwd -> /etc/passwd
lrwxrwxrwx 1 root root 11 Oct  8 15:34 /etc/cfm/compute-imaged-centos-5-x86_64/etc/passwd -> /etc/passwd
lrwxrwxrwx 1 root root 11 Oct  8 15:34 /etc/cfm/installer-centos-5-x86_64/etc/passwd -> /etc/passwd

Code:

[root@master ~]# ls -l /etc/passwd
-rw-r--r-- 1 root root 1579 Oct 13 09:09 /etc/passwd

and the following:

Code:

[root@master ~]# ls -l /opt/kusu/cfm/*/etc/passwd
-rw-r--r-- 1 apache apache 910 Oct 13 09:10 /opt/kusu/cfm/1/etc/passwd
-rw-r--r-- 1 apache apache 910 Oct 13 09:10 /opt/kusu/cfm/2/etc/passwd
-rw-r--r-- 1 apache apache 910 Oct 13 09:10 /opt/kusu/cfm/3/etc/passwd
-rw-r--r-- 1 apache apache 910 Oct 13 09:10 /opt/kusu/cfm/4/etc/passwd

The content looks like BASE64 encoded, but I cannot decode it with base64 ...

Code:

[root@master ~]# cat /opt/kusu/cfm/4/etc/passwd

Sadly my system clock is a little flacky as my installer node currently is a virtual machine...

Ok I found out that the content is openssl encoded and got it decoded.

My /etc/passwd is in fact overriden by /opt/kusu/cfm/*/etc/passwd, how does cfm decide what to overwrite?

ltsai: Do you have something more for me to try, or do you want me to open a bugreport now?

Maybe I am just using something wrong ...

ltsai · #7 (**permalink**) October 14th, 2008, 01:07 PM

Please go ahead and file a bug.

Thanks,
Liming

_fmms_ · #8 (**permalink**) October 14th, 2008, 02:03 PM

I have been playing for several hours now with it. And just now it started to work. (without actually changing anything)

I will report back if it stop working...

Thanks and sorry for the noise

ltsai · #9 (**permalink**) October 15th, 2008, 01:23 PM

Not a problem. Let us know if you run into further problems.

_fmms_ · #10 (**permalink**) October 15th, 2008, 02:40 PM

Sadly this appeared again, but a plain cfmsync -f does work fine and updates my files as expected. On reboot it breaks but this is due to the really bad clock of my vmware afaik.

I am still not sure what would have been the best for updating, see:
How to update the base kit to 1.0?
