Re: Mondo 3.2.2 issues

On CentOS 7:

<scratches head>  I see initrd.img in the root of the #1 ISO.  I also see images/all.tar.gz that would seem to be rather important.

I've unpacked both into a temporary filesystem.  usr/sbin/mondorestore appears in images/all.tar.gz, but not in initrd.img.  I'd have to bet that images/all.tar.gz is supposed to be getting unpacked after the boot phase 1.  Unpacking both results in about 1.25gb of space, so a 4gb RAM disk should be way more than sufficient.  Unfortunately, until I get the base ramdisk issue sorted out, I'm sunk, as practically nothing is available at the Mindi command line.

On CentOS 6:

Name resolution still succeeds, but the NFS mount still fails during a mondorestore run.  Well, wait.  Name resolution succeeds after the boot is fully complete and leaves me at a command line (expert mode.)  Name resolution *IS* failing during the boot phase 1, not sure that's entirely significant.  http:// 140.190.50.94/mondorestore-3.3.0-CentOS6-20191122-1.log

You can take the initrd made and extract it to see which size you get (was also thinking to recursive symlinks)

Good morning, Bruno.

Updated the CentOS 6 host, and rerunning.

I don't have any bind mounts on the CentOS 7 host at all, let alone on /proc.  So, maybe I should be looking at this from the other side.  What is being expanded on the #1 ISO image?  I'll also see if I can crank through strace on an nslookup.  I have a funny feeling that the ramdisk issue needs to be sorted out first.

Thanks for these details.

>The host has been configured to use the CentOS 6 test repository.  /etc/resolv.conf appears to be set up properly.

Ok great. On EL7 we may have an issue with missing dynamic libraries or something else. IIRC strace is delivered in the env, so you may be able to use it to discover what gets wrong.

>Even more interesting..... the ramdisk issue I've been running into on CentOS7 is not an issue on CentOS6.

Thanks for the diagnostic. So EL7 is providing a file expanding in a way too large one somehow.
You don't have a bind mount on /proc elsewhere e.g. on your FS on EL7 ? That could explain stuff.
Often that is used for chrootted daemons like named.

Bruno.
