Re: [CentOS] CentOS 7, NSF, "feature" [SOLVED]

The issue: NFS fails to start in CentOS 7 if it cannot resolve any of a list of hosts. Well, my manager had to google to find the *truly* obscure solution that uses a deeply oddball syntax. In /usr/lib/systemd/system/nfs-server.service, you edit the following line so that it looks like this:

[CentOS] CentOS 7, NSF, "feature"

In the last month, we've discovered a new, a, "feature" in the version of the version of NFS with CentOS 7: on startup, if it cannot resolve a given host, it dies. It does not continue on up, with all the other hosts it's exporting to, and just log a message. Is there a workaround, or a

[CentOS] In A UEFI World, "rm -rf /" Can Brick Your System

Excerpt: Running rm -rf / on any UEFI Linux distribution can potentially perma-brick your system. As a public service announcement, recursively removing all of your files from / is no longer recommended. On UEFI distributions by default where EFI variables are accessible via /sys, this can now

[CentOS] CentOS 7 and network printers: FYI

I got an email from a user that I'd just handed a new CentOS 7 workstation to, wondering where all the printers were. It took some investigation to find /etc/cups/cups-browsed.conf, and see, in it, at the very bottom of the file: # NOTE: This file is not part of CUPS. You need to start & enable

Ok, more info. I've just looked at the rdsosreport from a 327 kernel, and the one from this morning, from the 229-20 kernel, and I see where they croak: [3.045600] lym.cit.nih.gov systemd[1]: Found device ST500NM0003-9ZM172 /. [3.045950] lym.cit.nih.gov systemd[1]: Starting File System
