Re: [CentOS] CentOS 7: software RAID 5 array with 4 disks and no spares?
Hi Niki, md127 apparently only uses 81.95GB per disk. Maybe one of the partitions has the wrong size. What's the output of lsblk?

Hi, I just replaced Slackware64 14.1 running on my office's HP Proliant Microserver with a fresh installation of CentOS 7. The server has 4 x 250 GB disks. Every disk is configured like this : * 200 MB /dev/sdX1 for /boot * 4 GB /dev/sdX2 for swap * 248 GB /dev/sdX3 for / There are supposed to be no spare devices. /boot and swap are all supposed to be assembled in RAID level 1 across 4 disks. The / partition is supposed to be assembled in RAID level 5 across 4 disks. With Slackware I created the arrays manually like this: # mdadm --create /dev/md1 --level=1 --raid-devices=4 --metadata=0.90 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 # mdadm --create /dev/md2 --level=1 --raid-devices=4 --metadata=0.90 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2 # mdadm --create /dev/md3 --level=5 --raid-devices=4 --metadata=0.90 /dev/sda3 /dev/sdb3 /dev/sdc3 /dev/sdd3 Using this setup, I had 650 MB of disk space on /dev/md3. Now I tried to do the same thing with CentOS 7.

Re: [CentOS] CentOS 7: software RAID 5 array with 4 disks and no spares?
Hi Niki, in fact all of the sdX3 partitions are of size 76.4G. Maybe they were created by the installer as part of a partition scheme and you forget to resize them when removing other partitions from the scheme? Anyway, it should be fine if you recreate the partitions with the right size and then recreate the array.

Re: [CentOS] Help with routing question.
Hi James, Antonio is correct. The default address is used when the destination address is not on a subnet that is on one of your local interfaces. Any packet destined for an address on the 192.168.6.0/24 subnet will automatically be sent with a source address of 192.168.6.1 Same with any packet destined for an address on the 216.185.71.0/24 subnet will be sent with a source address of 216.185.71.1. The kernel uses the first address on an interface as the primary address. You can see this if you just do ifconfig ifname, you will only see the first address you assign to the interface.

The problem is that when we try to establish an ssh connection off-site to another netblock altogether the host uses 192.168.6.x as the source and the destination gets the public side IP address of our gateway router as the point of origin due to masquerading. I have solved this by explicitly binding ssh to the public ipv4 when connecting using the --bind=216.185.71.x parameter. But I have two questions I would like to find answers for 1. Why is ssh using the private IP in preference to the public IP when connecting to off-site addresses? 2. How does one configure the routing table on network startup to specifically detail the route particular addresses are supposed to take?

Usability anyone? installer is organized around mount points is correct, and what gets mounted on mount points? Volumes, not partitions. So it's consistent with the UI that the size is a volume size, not a partition size. The problem here, is that users are used to being involved in details like making specific partitions in a specific order with specific sizes. The new UI de-emphasizes the need to be involved in that level of detail. It ends up making things more consistent regardless of which device type you use: LVM, LVM thinp, standard, or Btrfs. If you emphasize partitions, then you have to emphasize the user needing to know esoteric things. What is NOT obvious: for single device installs, if you omit the size in the create mount point dialog, the size of the resulting volume will consume all remaining space. But since there's no way to preset raid5 at the time a mount point is created (raid5 is set after the fact), there isn't a clear way to say use all remaining space for this. There's just a size field for the volume, and a space available value in the lower left hand corner. -- Chris Murphy ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Le 19/02/2015 05:43, Chris Murphy a écrit : My personal view on installers is extremely biased toward the user staying out of trouble, they shouldn't have to read documentation for a GUI installer. A *user* never has to even see - or use - an installer. A USER has to USE a computer, by which I mean the applications he or she needs to get some work done. The person who gets to be confronted by an OS installer is not a user, it's an ADMIN, which is an entirely different thing. An ADMIN should RTFM (a lot) and know his way about what you call esoteric things earlier in this thread (disks, partitions, volumes). My company (http://www.microlinux.fr) installs complete Linux-based networks for schools, town halls, public libraries etc. here in South France. For now, most of my server and desktop solutions are based on a highly modified version of Slackware Linux, with some CentOS and some RHEL here and there. I'm currently planning on migrating everything to CentOS in the long run. One of the founding principles of my company is the constant SEPARATION BETWEEN USING A COMPUTER AND ADMINISTRATING IT. A user never ever has to worry about things that pertain to system administration, and it would be very wrong if he or she ever has to deal with such a thing as an installer. For what it's worth, some of my users don't even know that this thing that they're using every day is called Linux under the hood. To them, it's just the machine that's running things like their library management software, or whatever. So, as an admin, what I want from an installer is FLEXIBILITY... and not an assistant that reminds me of Microsoft Office's infamous Clippy and expects me to jump through burning loops to configure the system as I want it.

Re: [CentOS] CentOS 7: software RAID 5 array with 4 disks and no spares?
On Wed, Feb 18, 2015 at 3:59 PM, Niki Kovacs i...@microlinux.fr wrote: Well, maybe it's just me. I've started Linux on Slackware 7.1 and used pretty much every major and minor distribution under the sun. I know my way around Slackware, Debian, CentOS, FreeBSD, Gentoo, Arch and many more, and my favourite installer is - and will always be - Slackware's bone-headed NCurses installer that lets the admin do pretty much what he wants - and needs - to do. I'm definitely not suggesting it's just you. I'm coming up with a plausible explanation for the confusion, and that's a misalignment between your expectations and the installer's presentation. I can tell you, having using this installer since Fedora 18, it has changed immensely from the initial versions. My personal view on installers is extremely biased toward the user staying out of trouble, they shouldn't have to read documentation for a GUI installer. The entire point of a GUI installer is to protect the user from bad choices, non-standard or unsupportable choices, or having to read a volume of documentation, or become an expert for something that quite frankly happens rarely: OS installation. And my very strong bias is affected by both the OS X and Windows installers, which are completely, utterly, brain dead. And I mean that in a good way. It's impossible for the user to get confused, there are almost no choices. It's next to impossible for there to be bugs, there are almost no choices. Every outcome of the installation is supportable, because the user wasn't allowed to create completely nutty layouts that make no sense. Now, for various reasons Anaconda (the Fedora/RHEL/CentOS installer) is exceptionally more capable than almost any other GUI installer out there. And that makes it complex, prone to bugs, and prone to confusing users and subject to criticism. That's just the inevitable result of trying to do so many things. I love CentOS, been using it since 4.x. But frankly, CentOS 7's installer is an abomination. Having done many hundreds, possibly over a thousand installations with it, I'm well aware of how confusing it can be. So the criticism is almost certainly reasonable, no matter what. I'm just saying that once you understand the point of view of the installer (which arguably you should not have to do), things become much easier. That doesn't mean easy. Just easier. All's well that ends well. It only took me a day and a half to figure out how to configure RAID 5 using the graphical assistant. Something I could have done in less than three minutes using fdisk and mdadm --create. Right, but inevitably that failure is the result of misalignment of expectations between you and the installer. That's an explanation, not an assignment of blame. The reason why working directly with partitions is easy for you, and what you expect, is simply because that's how you've always done it, since that's how all other installers behave. Anaconda is really the first installer that deemphasizes that. And I think that's a bold move, and for a GUI installer that's necessarily taking on a lot of complexity I think it's probably a good idea overall. But it does have a lot of bugs still... it's definitely doing things that I don't like. But any experienced sysadmin knows how users say it should work like X and how often they're wrong. They're just used to things that work like X and that's why they want this new problem to work that same way. So as a sysadmin or network engineer you ask questions to find out how to get the user from A to B, and the details of how it should work are your domain, your specialty, and ultimately they don't really care how it happens, they just want to get to B. And once that's well understood, you can get on with things. And one problem is the installer can't really have that kind of diplomatic conversation about what its worldview is, so that the user expectations re-align with the end goal in mind, not how to get there. -- Chris Murphy ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I don't see it happening because it seems there's no mandate to basically tell people what they can't have, instead it's well, we'll have a little of everything. Desktop OS that are the conquerers now? Their installers don't offer 100's of layout choices. They offer 1-2, and they always work rock solid, no crashing, no user confusion, essentially zero bugs. The code is brain dead simple, and that results in stability. *shrug* Long road. Long long long. Tunnel. No light. The usability aspects are simply not taken seriously by the OS's as a whole. It's only taken seriously by DE's and they get loads of crap for every change they want to make. Until there's a willingness to look at 16 packages as a whole rather than 1 package at a time, desktop linux has no chance. The very basic aspects of how to partition, assemble, and boot and linux distro aren't even agreed upon. Fedora n+1 has problems installing after Fedora n. And it's practically a sport for each distro to step on an existing distros installer. This is technologically solved, just no one seems to care to actually implement something more polite. OS X? It partitions itself, formats a volume, sets the type code, writes some code into NVRAM, in order to make the reboot automatically boot the Windows installer from a USB stick. It goes out of it's way to invite the foreign OS. We can't even do that with the same distro, different version. It should be embarrassing but no one really cares enough to change it. It's thankless work in the realm of polish. But a huge amount of success for a desktop OS comes from polish. We also pretty much don't use any drives under 1TB. The upshot is we had custom scripts for 500GB, which made 4 partitions - /boot (1G, to fit with the preupgrade), swap (2G), / (497G - and we're considering downsizing that to 250G, or maybe 150G) and the rest in another partition for users' data and programs. The installer absolutely does *not* want to do what we want. We want swap - 2G - as the *second* partition. But if we use the installer, as soon as we create the third partition, of 497GB, for /, it immediately reorders them, so that / is second. I'm open to having my mind changed on this, but I'm not actually understanding why it needs to be in the 2nd slot, other than you want it there, which actually isn't a good enough reason. If there's a good reason for it to be in X slot always, for everyone, including anticipating future use, then that's a feature request and it ought to get fixed. But if it's a specific use case, well yeah you get to pre-partition and then install. -- Chris Murphy ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I am not sure that I understand your question so if this answer is
totally irrelevant then please forgive me.
But, in case this might help, you can configure mock to use locally
provided repos and different architectures via the --configdir

epel-6-x86_64.cfg in the specified directory and alter it to require
packages to suit a specific build requirement.
One of mine looks like this:
config_opts['root'] = 'epel-6-x86_64'

config_opts['legal_host_arches'] = ('x86_64',)

Hi Adit,
If you are not already using TSIG's in your views I suggest you look at
this guide
http://blog.hudecof.net/posts/2014/02/07/bind9-with-views-and-tsig-axfr.html
It shows how to use TSIG's to identify the views so you can slave both
of them to the secondary.
also you want to add to the options section on the master
also-notify { slaves-IP; };
This make it tell the slave to update its zone.

But, I don't believe such a rebuild would be an exact binary match for the builds in the CentOS build environment and getting all the src rpms at the right versions would be just as hard as assembling all of the binary rpms and debuginfo from the vault versions.

The upshot is we had custom scripts for 500GB, which made 4 partitions - /boot (1G, to fit with the preupgrade), swap (2G), / (497G - and we're considering downsizing that to 250G, or maybe 150G) and the rest in another partition for users' data and programs.

Duh The result is that we get to the screen to choose the drive, and say custom partition... then alt-F2, and use parted to make the partitions, then go back to the GUI and just assign the mount points and filesystem types. And why would you *want* / to have everything?
