i guess ill just continue to use the chef/ images then.

TrevorH: Basically, www.centos.org doesn't support TLS 1.1 or 1.2, I was hoping to see those get adopted if at all possible.

Is there a difference between doing a groupinstall and installing all of the group's packages individually? If I install a group, and then later a package is added to the group, will yum update pick that up?
Ryein
TrevorH, how can i check my centos install for errors
TrevorH, i logged in from the install disk and set a password through recovery
so i can login now
how can i make sure everything installed properly
i did a yum update and everything worked ok
_val_
dgbaley: the groupinstall covers all packages that are assigned to that group. It's like iterating through a list of packages belonging to the group.
Ryein
TrevorH, also i am using software raid for these disks
should I use the motherboard raid controller instead?
harmaahylje
Ryein: would not recommend doing that
software raid is safer
Ryein
thats what i have been learning so far
harmaahylje
if your mobo breaks up, things will get interesting (if you use the mobo raid)
         

Ryein
makes sense
TrevorH
Ryein: if you now yum update and get a new kernel, does that install ok?
phuzion: that sounds like a suitable subject for a bug report to me
Ryein
TrevorH, yeah the new kernel installed ok and it rebooted fine
still not recognizing my SSD though
TrevorH
hmm, I wonder if that was the source of the problem
how do you mean, not recognising?
Ryein
It isn't showing up in the install and didn't show up when doing fdisk -l
was gonna use that for MySQL
not as the boot/install drives
alaird
the wiki mentions that centos-test is not available for 7 at this time. is there an alternate source for these bits?
TrevorH
what is it attached to?
Ryein
TrevorH, SATA port 3 on the motherboard
TrevorH, the other disks are on 4 and 5
Ubuntu detected it fine though
so i know its not the port
TrevorH
Ryein: pastebin the output of lspci -nn
Ryein
command not found
TrevorH
yum install pci-utils
or pciutils can't remember which
Ryein
lspci -nn
http://pastebin.com/jeM6uW0v
TrevorH
it is there just the intel 6 port sata controller on that board?
Ryein
yeah
TrevorH
right, I have the c226 ws and it has 2 more marvell sata controllers on it as well
pastebin the output of dmesg | grep ata
Ryein
TrevorH
[ 1.494218] ata3.00: ATA-8: SSD2SC240G5LC726B104-298, 560ABBF0, max UDMA/133
that looks like it to me
Ryein
so just mount it
?
TrevorH
look in /var/log/messages just after that line and see what else it says about it
you should also see lines like "scsi 6:0:0:0: Direct-Access ATA SAMSUNG MZHPV512 BXW2 PQ: 0 ANSI: 5"
only with your model number in it
and others that start with "sd 6:0:0:0"
numbers may vary
Ryein
I found a blog post about the install error I was getting http://www.dedoimedo.com/computers/centos-7.html
near the middle of the page he talks about it
         

TrevorH
the bit about swapon?
Ryein
yeah and then he talks about bootloader errors
TrevorH
were you using 7.1.1503?
Ryein
latest off the site
TrevorH
I'd report that as a bug on bugzilla.redhat.com, a quick search doesn't find an existing one but I didn't look hard
Ryein
yep thats the same version
everyone always recommends setting a static ip by looking at ifcfg but i only see ifcfg-lo
ifconfig shows enp3s0 being connected but it isn't in /etc/sysconfig/network-scripts/
do i create a new file?
TrevorH
sounds like you are using networkmanager so try using nmcli
sartan
openssh-askpass keeps asking for credentials when trying to authenticate to libvirtd. thinking it's got something to do with some nerd knobs i've got in pam. any ideas on how to look at debugging this? trying to virt-manager to a remote host. centos both sides.
tried from epel and from source, same issue.
TrevorH
virt-manager uses ssh to get to remote hosts
sartan
Yah. i've got a bunch of sssd stuff enabled for domain (AD) authentication, wondering if i'm having issues with openssh-askpass. also trid virt-manager --no-fork to do a cli password unlock, it just continually asks me for passwords over and over
TrevorH
look in /.var/log/secure on the remote server and see if you see connection attempts
ignoring the stray . that crept in there
sartan
Yeah, that's the first place I looked. All I get is a generic pam_unix(sshd:auth) authentication failure, for valid usernames
Interestingly, it accepts the password but still copmlains authenticaiton failure
just opens and closes session immediately
mspo
I'm seeing a pretty big performance different between 5 and 6 using this script: https://gist.github.com/msporleder/e689b0e0b5e40462edb0
also memcached performance giving the same
if I execute with numactl -C0 it is closer to 5.5 performance
numa=off in grub.conf didn't do anything
TrevorH
@uname mspo
centbot
mspo, please paste the single line of output from the 'uname -a' command run on the server in question to the channel.
mspo
Linux myhost 2.6.32-504.el6.x86_64 #1 SMP Wed Oct 15 04:27:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
TrevorH
you can try updating to the latest kernel and see if it's been fixed
yum update
hmm, the bug I was thinking of should already be fixed in -504 but you should update anyway
https://bugs.centos.org/view.php?id=6949
mspo
I'm trying numad right now but it doesn't seem to help memcached
I have a 6.3 I can try too, I think
same results 5.5 vs 6.3 vs 6.6
I feel like this is something I could tune my way out of (like ext4 vs ext3 stuff)
TrevorH
if it works on a -358 kernel then I do not think it is the bug I linked to
did you try any of the suggestions in that bug to see if they help?
export GOMP_CPU_AFFINITY="0-15"
mspo
i will try that for memcache
TrevorH: that made my script run worse or the same
keithr
Why is yum installed (and /usr/bin/yum removed) in the centos atomic image ? bad dependencies ?
Mathman
hi there. centos 7 isn't seeing my sound card it looks like. nothing listed when I run lspci. any advice?
hmm, frick. wonder if I disabled it in the bios...that could be a thing knowing me and this particular system
Motoko
That's a good possibility.
lspci should show all devices, even if not loaded by a module.
bdonnahue
anyone know what would cause /boot to not be mountable in a centos vm? having no luck in xenserver
this issue doesnt occure with centos 6 or other distros
TommyC
Could be lacking support for the filesystem the partition with /boot uses.
