CentOS 6.0 was actually obsolete the day it was released, as RHEL had already released 6.1, which CentOS followed with in a matter of weeks. the product is EL6, the .0, .1, .. are merely security rollups of the ongoing stream of updates and patches. -- john r pierceN 37, W 122 santa cruz ca mid-left coast ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I have a question: is it ok if the version of kernel-header and kernel-devel are not same? As you have been told, you really need to get on CentOS6 Update 3 (aka, 6.3) for security update purposes. Having said that, I'll address the rest of the list by saying that we do not know the particular requirements of the OP, and it is pretty clear from the thread that the OP does not have the discretion to do the update and must get approval from higher-ups. This sort of situation happens, and telling the OP to update, without addressing the actual question as well, is useless. The OP's higher-ups may have very particular reasons to want/need the older version, and we are not in a position to tell them that they are wrong; sure, staying current is the normally right thing to do, but there is a reason that Scientific Linux differs from CentOS is this respect, allowing people to take only security updates but stay at a particular point release. It makes their process more complicated, but it is their goal. Now, neither in my personal use of CentOS nor in my work use of CentOS have I yet found a need to stick to a particular point release, but that doesn't mean that a valid need to stick to a particular point release does not exist. If I were to find that I needed to stick to a point release for some reason, I'd probably use SL for that particular purpose and CentOS for the other systems. Now, to actually answer the OP's questions. I believe, but am not sure, that you do need the same versions of kernel-devel and kernel-headers and they must match the kernel version that you're using. You can get this older version of kernel-headers at: http://vault.centos.org/6.0/updates/x86_64/RPMS/kernel-headers-2.6.32-71.29.1.el6.x86_64.rpm The matching kernel-devel is at: http://vault.centos.org/6.0/updates/x86_64/RPMS/kernel-devel-2.6.32-71.29.1.el6.x86_64.rpm ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I have heard some positive feedback about http://zfsonlinux.org/ but I have not had time to test myself yet. It probably depends on your intended usage. It is a new in-kernel ZFS implementation (different from the old FUSE implementation). RHEL 6.2 x86_64 is listed as one of the supported OSes, so it probably works fine with CentOS too. There is some positive and negative feedback in the following links: https://groups.google.com/a/zfsonlinux.org/group/zfs-discuss/browse_thread/thread/5a739039623f8fb1 http://pingd.org/2012/installing-zfs-raid-z-on-centos-6-2-with-ssd-caching.html Please share your results if you do any testing :) -- Janne Snabb / EPIPE Communications sn...@epipe.com - http://epipe.com/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

In a nutshell, yes, it should be possible. It will be complicated, and might even be very complicated, but it actually sounds like a 'different from normal' application of mock or mock's predecessor, 'mach'. This is not the only way to do this sort of thing, but if you want to use yum to do the install. I do not have a specific procedure, but I can point you to a rather interesting document about running a Debian userland on top of SuSE linux at: http://www.network-crawler.de/index.php/Debian_within_SuSE (as a note, I learned about this even being possible at http://forums.nekochan.net/viewtopic.php?f=14t=16725842p=7344235#p7344235 and then googled from there). This uses chroot to do its magic. (seems I've read this really recently on another list. :-) ). There are limits to how far you can take this, but that document is a start at understanding the mechanics that make it work, and for what you want to do, if using yum is a requirement, this may be the way to do it (just not using Debian on SuSE, but something RPM-based on CentOS). The other recommendation of installing things via tarball is quite a bit simpler to set up, but will be more complicated to maintain and update over time. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Deduplication with ZFS takes a lot of RAM. I would not yet trust any of the linux zfs projects for data that I wanted to keep long term.

Thx Rainer Although not open source, CrashplanPROe only costs $365 for a perpetual five client license. I use it to backup some of my Linux boxes. It has very good deduplication, compression, and encryption. For example I have 1.7TB of data on one linux system and another system that has 1.5TB. I NFS mount one of the systems to another and only use one Crashplan client to backup both data sets to a single backup archive. The backup archive is only 1.2TB and that also spans 90 days worth of file modification and deletion I can recover.

Re: [CentOS] netinstall
I'm a newcomer to CentOS. Fedora 14 was the last Fedora version I managed to make work. Fedora 16 I couldn't install at all. Fedora 17 installed, but I couldn't make it work right. I'd been trying to do media-less installs because Fedora wouldn't read my DVDs anymore. What directions I could find for installing CentOS without media were not all that clear to me, so I did some guesswork informed by some of the Fedora documents. I used the following grub stanza: title Install Centos 6.2 from net install iso find /centos/vmlinuz root (hd1,9) pause paused kernel /centos/vmlinuz method=http://mirror.anl.gov/pub/centos/6/2/os/i386 initrd /centos/initrd.img The find and pause were not really necessary. I think vmlinuz and initrd.img were copied from a net_install.iso file. Much to my surprise, it worked the first time. -- Michael henne...@web.cs.ndsu.nodak.edu On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword. -- Lily ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
