These packages are following the upstream Gluster Community releases, with one minor update for each version per month. Users of CentOS 6 can now simply install Gluster with only these two commands: # yum install centos-release-gluster # yum install glusterfs-server The centos-release-gluster content comes from the centos-release-gluster37 package delivered via CentOS Extras repos. This contains all the metadata and dependancy information, needed to install Gluster 3.7. For people looking at running Gluster 3.6, there is the centos-release-gluster36 package. In order to get this version, substitute the step-1 mentioned above with: # yum install centos-release-gluster36 We have a quickstart guide specifically built around the packages are available now, it makes for a good introduction to Gluster and will help get you started in just a few simple steps, this quick start is available at https://wiki.centos.org/SpecialInterestGroup/Storage/gluster-Quickstart More details about the packages that the Gluster project provides in the Storage SIG is available in the documentation: https://wiki.centos.org/SpecialInterestGroup/Storage/Gluster The centos-release-gluster* repositories offer additional packages that enhance the usability of Gluster itself. Users can request additional tools and applications to be provided, just send us an email with your suggestions. The current list of packages that is (planned to become) available can be found here: https://wiki.centos.org/SpecialInterestGroup/Storage/Gluster/Ecosystem-pkgs Gluster is the first project that provides packages through the Storage SIG. Other projects are in the process to do so too. General information about the SIG can be read in the wiki: https://wiki.centos.org/SpecialInterestGroup/Storage We welcome all feedback, comments and contributions. You can get in touch with the CentOS Storage SIG on the centos-devel mailing list ( https://lists.centos.org ) and with the Gluster developer and user communities at https://www.gluster.org/mailman/listinfo , we are also available on irc at #gluster on irc.freenode.net, and on twitter at @gluster .

CentOS 7 magically rebooted!
by Tom Robinson 22 Jan '16

22 Jan '16

CentOS Linux release 7.2.1511 (Core) Hi, Last night our CentOS 7 server rebooted. Seemingly it's a very clean reboot. I can't find a shred of evidence as to why it happened though. Things I've checked: * sa reports * /var/log/{messages,secure,dmesg,cron} * /var/log/audit/audit.log * lastlog The host is used for KVM virtualisation and connects via multipathing to our OmniOS SAN via infiniband. I can provide any logging you may think helpful Here's an excerpt from /var/log/messages at the time of reboot: ---8<--- Jan 21 23:32:01 daytona systemd: Starting Session 10964 of user root.

snat packet going out a bridge

Hi List, I am running into a problem where I have 2 interfaces bridged with and ip address assigned. I have another interface in which traffic has ingress traffic that needs to go out the bridged interface. I am trying unsuccessfully to SNAT the traffic leaving the bridge interface to its assigned address. # brctl show xbrdg0 bridge name bridge id STP enabled interfaces xbrdg0 8000.000c297aa55f no eth0 eth1 # ip a s xbrdg0 11: xbrdg0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 00:0c:29:7a:a5:5f brd ff:ff:ff:ff:ff:ff inet 192.168.100.3/24 scope global xbrdg0 # ip a s eth5 7: eth5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:0c:29:7a:a5:7d brd ff:ff:ff:ff:ff:ff inet 10.10.0.1/29 scope global eth5 default via 192.168.100.1 dev xbrdg0 So I want traffic coming in eth5 with 10.10.0.x addresses to be source natted to 192.168.100.3.

Radeon driver with HD 2600 pro and dual head
by Tim 21 Jan '16

21 Jan '16

Hey list, I got a problem with a Gigabyte radeon HD 2600 pro card regarding my multi head setup with . This card has two DVI connectors. The second monitor has the state of being disconnected after startup (xrandr -q). When I disconnect it and reconnect sometimes the screen comes up and the second monitor shows up in display settings. It doesn't matter which port of the card I use first - the other one is disconnected. Any idea where I can take a look at? Thanks in advance Regards Tim

signing RPM packages with SHA256
by Alice Wonder 21 Jan '16

21 Jan '16

hi, I noticed that RPM packages I sign use SHA1 Signature : RSA/SHA1, Fri 08 Jan 2016 10:50:58 AM PST, Key ID ad3b591d147abf59 Signatures from CentOS 7 use SHA256 Signature : RSA/SHA256, Wed 06 Jan 2016 08:54:58 AM PST, Key ID 24c6a8a7f4a80eb5 I'm trying to find where / how to use sha256 when I sign packages but I am not having much luck. Closest I have found is this : https://fedoraproject.org/wiki/RPM_file_format_changes_to_support_SHA-256 That page appears to be from 2009 and six years is a really long time, things change a lot. Is there an up to date reference somewhere on RPM package signing that I haven't stumbled upon yet? SHA1 is broken. I shouldn't be using it. CentOS 7 is all I build packages for. Thank you.

ifenslave vs. /etc/sysconfig/network-scripts
by Nicholas Geovanis 21 Jan '16

21 Jan '16

How does the ifenslave command relate to "normal" network slave configuration in /etc/sysconfig/network-scripts? Does config-file-based setup use ifenslave or is it more complicated than that? Thanks....Nick

LVM thin volumes fstrim operation not supported
by Tim Robinson 20 Jan '16

20 Jan '16

Hi All I'm trying to setup my LVM thin pool to support discards so that the pool can reclaim space even if the underlying device doesn't support trim. It is my understanding that all thin pools should support trim even if the underlying device doesn't. (please correct me if I'm wrong here) I have one centos server that does support trim and everything is working correctly but any new servers and thin pools throw the error below. # fstrim -v /mnt/data00 fstrim: /mnt/data00: the discard operation is not supported I can't find any differences in the LVM configuration between the two servers, they both have the lv discards set to passthough. Can anyone tell me if I'm missing something when creating the thin pool that would allow me to perform the fstrim. I'm using xfs on all of the lvs. Thanks, Tim

Setting up a userID for an SSH tunnel
by Robert Moskowitz 19 Jan '16

19 Jan '16

I need/desire to set up a userID for an SSH tunnel, but not allow said user to have a login to the server. For the user to set up the tunnel with: ssh -p 1234 -L 8080:192.168.1.4:80 george(a)gateway.foo.com Where george would use a password instead of a stored SSH key, could george be created with: useradd -s /sbin/nologin -c "George" george passwd george thanks

Hi, Does anybody tried to install Skype on Centos 7.2? It is giving a segmentation fault when you start it. I installed using the nux repository and the fedora rpm.

gfortran "static" linking on CentOS 7
by Kay Diederichs 16 Jan '16

16 Jan '16

Dear all, on CentOS 6 one could use -static-libgcc -static-libgfortran to obtain a binary which would run on other computers which don't have gfortran installed. On CentOS 7 one can install the libgfortran-static and libquadmath-static RPMs but the resulting binary _still_ requires /lib64/libquadmath.so as revealed by ldd. gfortran does not recognize an option like -static-libquadmath . libquadmath is required even for tiny programs which do not use high precision data types. Heavy use of Google did not bring any result. I tried with linker options -Wl,-Bstatic and so on, but without changes. So, can anyone tell me how to compile/link with gfortran a binary which does not have a requirement for libquadmath? If this is not possible, why are there libgfortran-static and libquadmath-static RPMs ? thank you, Kay

grub2-mkconfig strange error
by Timothy Murphy 15 Jan '16

15 Jan '16

When I run "grub2-mkconfig" on my CentOS-7.1 desktop I get the warning (4 times) /usr/sbin/grub2-probe: error: cannot find a GRUB drive for /dev/block/8. Check your device.map. What exactly does this mean? My device map looks perfectly normal to me: [root@helen ~]# cat /boot/grub2/device.map (hd0) /dev/sda (hd1) /dev/sdb This makes me reluctant to boot into CentOS-7.2. An additional, possibly related, query. When I run grub2-mkconfig it lists various OS's it finds: ========================= Found Windows 7 (loader) on /dev/sda1 Found CentOS Linux release 7.1.1503 (Core) on /dev/sda12 Found Windows 7 (loader) on /dev/sdb1 Found CentOS release 6.5 (Final) on /dev/sdb5 Found CentOS release 5.6 (Final) on /dev/sdc7 done ========================= Why does it not list CentOS 7.2 since it ========================= Found linux image: /boot/vmlinuz-3.10.0-327.4.4.el7.x86_64 Found initrd image: /boot/initramfs-3.10.0-327.4.4.el7.x86_64.img ========================= -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin
