Possible bug in kickstart
by James A. Peltier 26 Jun '15

26 Jun '15

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the installation starts off the creation of bond0 and all VLANs on bond0 go without issue. Jumping into TTY2 I can type 'ip a' and see all the bond0 device and bond0.VLANID devices no problem. When I enable bridge content with --bridgeslaves=bond0 or --bridgeslaves=bond0.VLANID anaconda barfs When I enable bridge content with --bridgeslaves=em1 or --bridgeslaves=em2 anaconda doesn't have an issue. Is this expected behaviour? I really don't want to have to manually manipulate the ifcfg-bond* interfaces and create the ifcfg-BRIDGE* interfaces manually so I'd like this to work. # Configure a bond over the slaves in failover mode network --device=bond0 --noipv6 --bootproto=dhcp --onboot=yes --bondslaves=em1,em2 --bondopts=mode=active-backup;primary=em1 --activate # Configure VLANs network --device=bond0 --vlanid=11 --noipv6 --onboot=yes --bootproto=dhcp --activate network --device=bond0 --vlanid=100 --noipv6 --onboot=yes --bootproto=dhcp --activate network --device=bond0 --vlanid=302 --noipv6 --onboot=yes --bootproto=dhcp --activate network --device=bond0 --vlanid=303 --noipv6 --onboot=yes --bootproto=dhcp --activate network --device=bond0 --vlanid=304 --noipv6 --onboot=yes --bootproto=dhcp --activate network --device=bond0 --vlanid=306 --noipv6 --onboot=yes --bootproto=dhcp --activate # Create a bridge on the bonded VLAN interfaces network --device=FASNET --bridgeslaves=bond0 network --device=GLUSTER --bridgeslaves=bond0.11 network --device=EXPERIMENTAL --bridgeslaves=bond0.302 network --device=NAT --bridgeslaves=bond0.303 network --device=DMZ2 --bridgeslaves=bond0.304 network --device=NETM --bridgeslaves=bond0.306 -- James A.

An odd X question
by m.roth＠5-cent.us 26 Jun '15

26 Jun '15

I've got a headless server running CentOS 7. I've got a user who wants to run some graphical software on it, and view using x forwarding. What I don't have clear is how to set this up. I've just installed xorg-x11-server-[Xorg, common]. I assume I need to run X, but I don't see running this in runlevel 5. Thoughts? mark "and why is it called xorg-x11-server, when in X terminology, it's the client?"* * Which I always thought was bass-ackward, but...

LVM hatred, was Re: /boot on a separate partition?

LV-backed VMs have *dramatically* better disk > performance than file-backed VMs. I did a bunch of testing of Raw, qcow2, and LV backed VM storage circa Fedora 19/20 and found very little difference. What mattered most was the (libvirt) cache setting, accessible by virsh edit the xml config or virt-manager through the GUI. There have been a lot of optimizations in libvirt and qemu that make qcow2 files perform comparable to LVs. For migrating VMs, it's easier if they're a file. And qcow2 snapshots are more practical than LVM (thick) snapshots. The thin snapshots are quite good though they take a lot of familiarity with setting them up. -- Chris Murphy

LVM hatred, was Re: /boot on a separate partition?
by Chris Murphy 25 Jun '15

25 Jun '15

Chris Adams linux at cmadams.net Wed Jun 24 19:06:19 UTC 2015 >Btrfs may eventually obsolete a lot of > uses of LVM, but that's down the road. LVM is the emacs of storage. It'll be here forever. Btrfs doesn't export (virtual) block devices like LVM can, so it can't be a backing for say iSCSI. And it's also at the moment rather catatonic when it comes to VM images. This is mitigated if you set xattr +C at image create time (it must be zero length file for +C to take). But if you cp --reflink or snapshot the containing subvolume, then COW starts to happen for new writes to either copy; overwrites to either copies newly written blocks are nocow. So anyway you can quickly get into complicated states with VM images on Btrfs. I'm not sure of the long term plan. This is how to set xattr +C at qcow2 create time, only applicable when the qcow2 is on Btrfs. # qemu-img create -o nocow=on But really piles more testing is needed to better understand some things with Btrfs and VMs. It's all quite complicated what's going on with these layers. Even though my VM images get monstrous numbers of fragments if I don't use +C, I haven't yet seen a big performance penalty as a result when the host and guest are using Btrfs and the cache is set to unsafe. Now, you might say, that's crazy! It's called unsafe for a reason! Yes, but I've also viscously killed the VM while writes were happening and at most I lose a bit of data that was in flight, the guest fs is not corrupt at all, not even any complaints on the remount. I've got limited testing killing the host while the writes are happening, and there is more data loss due to delayed allocation probably, but again the host and guest Btrfs are fine - no mount complaints at all. And you kinda hope the host isn't often dying... NTFS in qcow2 on Btrfs without +C however? From Btrfs list anecdote this combination appears to cause hundreds of thousands of fragments in short order, and serious performance penalties. But I haven't tested this. I'm guessing something about NTFS journalling and flushing, and suboptimal cache setting for libvirt is probably causing too aggressive flushes to disk and each flush is a separate extent. Just a guess. -- Chris Murphy

Flexibility is worth an ounce of complexity. I think LVM is badass, however if you don't know the LVM tools, you're instantly tossed deep into the weeds. Most every letter, lower and upper case, seems to be used twice by each of the lvm commands. I don't have enough fingers to count the number of lvm commands. There's so much intricate detail required for creating LVM layouts and doing snapshots and snapshot deletion compared to Btrfs that I've just about given up on LVM. I've also never had Btrfs snapshots explode on me like LVM thinp snapshots have when the metadata pool wasn't made big enough in advance (and it isn't made big enough by default, apparently). Most any typical maneuver done on LVM can be done much more easily and intuitively with Btrfs. So these days I just focus on Btrfs even though I definitely don't hate LVM. On desktop Linux, making LVM the default layout I think is a bad decision. It causes mortal users more trouble than it's worth. I'd be a bit more accommodating if LVM had integrated encryption with live bi-directional conversion. -- Chris Murphy

It is a web based system administration tool that I find invaluable. The two most common complaints I encounter when I discuss its merits are 'security' and 'transparency'. The security issue is trivially dealt with. Install Webmin and configure it to listen on 127.0.0.1 using its standard port TCP10000. Install Firefox on the same host and then run firefox from an 'ssh -Y' session using the --noremote option. If you are totally paranoid then firewall TCP10000 as well, configure Webmin to use https only, and then only start the webmin service when you are performing maintenance. There are less draconian measures that are in my opinion equally secure from a practical standpoint but I am sure that you can figure those out on your own. The transparency issue is really unanswerable. There exists a school of thought that if you are going to administer a Linux system (or OS of the proponent's choice) then you should learn the command syntax of every command that you are called upon to use. This is the one-and-only path to enlightenment. Like upholding motherhood and promoting the wholesomeness of apple-pie this sort of moralizing really brooks no answer. You can guess my opinion on that line of puritanism. As you have painfully discovered, infrequently used utilities and commands are difficult to deal with. The process of learning, or relearning, the correct arcana is particularly noisome given the notorious inconsistency of syntaxes across different utilities and the spotty coverage of up-to-date documentation. Google can be a dangerous guide given the wide variation of practice across differing flavours of *nix and the widespread aversion to providing dates on writings. In consequence I consign transparency arguments and their proponents to the religious fanatic file. Nothing personal but there is no point in arguing belief systems. If you want to get infrequently performed sysadmin tasks done reliably and with a minimum of fuss use something like Webmin and get on with the rest of your life. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

I am trying to load centos on a gen opteron x86 but since the boxes are out of support, I am unable to find firmware for it. Any suggestions on where I might find the drivers? Thanks, Dan
