Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]
by Yannis Milios 02 Feb '25

02 Feb '25

Hello, I'm having a strange problem booting a new centos7 installation. Below some background on this. [I have attached the tech details at the bottom of this message] I started a new CentOS7 installation on a VM, so far all good, o/s boots fine. Then I decided to increase VM disk size (initially was 10G) to 13G. Powered off the VM, increased the vhd via the hypervisor, booted from CentOS livecd, selected "recover my centos installation". Then I used the following sequence of commands to make the new vhd size "visible" to the o/s ... - ran fdisk /dev/sda and deleted partition 2. (This is the LVM partition where the o/s is stored. The first partition is /boot [xfs] partition *non lvm*.) - created a new partition with same starting sector as before deleting it, but a different ending sector (to reflect to the increased space). - set partition type to 8e (lvm), saved settings and exit. - ran pvresize and lvresize to make new space visible to the o/s.All good, I can see the space increase on 'lvdisplay centos/root'. - ran 'mount /dev/mapper/centos-root /mnt/root' to temporarily mount the o/s partition. - ran 'xfs_growfs /mnt/root' to resize the o/s fs to the new size. It was successful and I could actually chroot to the o/s and verify new disk size. - rebooted and tried to boot from hdd this time. Grub menu shows up and loads default kernel (3.10.0-862.9.1.el7.x86_64). - after initial kernel boot up process, booting continues to initrd and then it's where the problem starts... - looks like dracut has issues locating/enabling /dev/mapper/centos-root (lv) and as a result it cannot boot to the 'real' root fs (/). - while in dracut shell, I execute the following command sequence: 1. lvm lvchange -ay /dev/centos/root 2. lvm lvchange -ay /dev/centos/swap 3. ln -s /dev/mapper/centos-root /dev/root 4. exit ...and the o/s boots fine...so looks like the pv,vg,lv is detected properly while in initrd, but somehow dracut has difficulties enabling the root,swap LVs ? - While in o/s, I rebuild initrd by using: 'dracut -f -v -a lvm' Note, I have to use '-a lvm' as for some reason, if don't, the lvm utils (lvm,lvm_scan) are not being included to the initrd, not sure why this happens. After rebooting, same thing happens, I have to manually boot the system via dracut shell. I'm a bit stuck at this point, any clues what I'm doing wrong in here ? As I previously said, this is a new installation, so I could simply reinstall the whole thing, but I would rather try to find out some answer to why is this happening ... :-) [curiosity] Some additional details: ================== I've attached /run/initramfs/rdsosreport.txt file [generated while in inird] here: https://privatebin.net/?fdc4052c0c402884#gdB/QYR3IeR55SxUbjfrkZPQfJ7jMxiUxq… o/s ver=CentOS Linux release 7.5.1804 (Core) [root@localhost ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 13G 0 disk ├─sda1 8:1 0 500M 0 part /boot └─sda2 8:2 0 12.5G 0 part ├─centos-root 253:0 0 11.5G 0 lvm / └─centos-swap 253:1 0 1G 0 lvm [SWAP] [root@localhost ~]# cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rd.shell rhgb" GRUB_DISABLE_RECOVERY="true"

MATE 1.20 test build for CentOS 7 available
by Greg Bailey 14 Oct '21

14 Oct '21

Hi everyone, There's been discussions in the past about updating MATE RPMs in EPEL-7: https://bugzilla.redhat.com/show_bug.cgi?id=1436260 https://lists.centos.org/pipermail/centos/2019-August/173154.html (and lots of others...) As a proof-of-concept, I've written some scripts that clone specific commits from the Fedora master branches, and then runs a tool to re-apply RPM scriptlets that are required by EL7 but removed from the Fedora .spec files. The scripts are available at: https://github.com/gebailey/mate-rpms/tree/master/1.20/el7 There's also instructions there if you want to try upgrading to MATE 1.20 w/o rebuilding them yourself. If these packages work for others, perhaps we can revisit the idea of updating the epel7 branches of the Fedora git repos and submitting an official update. There's nothing here (yet) about building MATE 1.22 (which might require a newer gcc for EL7), or building anything on CentOS 8, but thought the CentOS 7 users might find this helpful. -Greg

Transition test report going from CentOS8 to Debian 10.
by Lamar Owen 06 Aug '21

06 Aug '21

Sorry for the length.... I'm posting this here since this particular transition has been mentioned on-list as one possibility for a path forward for current CentOS Linux users. AlmaLinux, the Developer Subscription RHEL, Rocky, CentOS Stream, Springdale, upgrading to full RHEL; all these are also possibilities, too, and all have different strengths and weaknesses. The transition to Debian has a lot of strengths, including a long track-record of support (even if the support time for a particular release is shorter), a fully-open development model with no 'corporate overlord' that I know of, a large set of supported packages, and a huge community of developers and users. For the CentOS user the main weakness is having to learn a few areas of difference in the way the system is setup and maintained; of course, if a ten-year 'stable' timeframe is really that important to you the lack of that is also a weakness. So, last week I transitioned, as a test of sorts, my working CentOS 8 main laptop to Debian 10. I kept a complete backup of the C8 install should I wish to go back to it, and installed Buster to a new mSATA SSD, but ported the two SATA drives (Dell Precision M6700 - has an mSATA slot plus two SATA bays) straight over after making full backups. I posted a pretty complete rundown on the scientific linux users mailing list, so I won't recap it all here. The bottom line was the the transition was not any more difficult, really, than moving from CentOS 7 to CentOS 8. The software versions in Buster are pretty close to what is in CentOS 8, although I have yet to need any third-party repository (PPA) for anything I've needed to install. All the packages I have worked with so far have worked fine with a little bit of massaging. These include commercial (and costly) software such as Harrison Consoles' Mixbus32C, Qoppa's PDFStudio2019 Professional, and others. So if you were to decide that this is the route for you to take, it does work and I found it to be not nearly as hard as I had thought it might be. If you install GNOME 3 you get GNOME 3; it feels pretty much the same as a non-Classic CentOS GNOME 3, just with a different set of extensions installed by default. That's on the workstation. On the server side, I'm evaluating Proxmox for the virtualization solution, and so far I'm finding it to be a pretty easy migration. I'm using the 'non-subscription' repository, so this is a no-cost option. Even getting the box registered to our EMC Clariion SAN was relatively easy; EMC provides the Unisphere Server Utility for Linux x64 in RPM form; the latest I have is "ServerUtil-Linux-64-x86-en_US-1.0.55.1.0044-1.x86_64.rpm" (which is fairly old, but I did say Clariion arrays, so they're pretty old, too). Debian has provided the 'alien' tool for some time; after installing alien, a simple 'alien -i ServerUtil-Linux-64-x86-en_US-1.0.55.1.0044-1.x86_64.rpm' installed the EMC RPM in the correct place. Proxmox already included everything that serverutilcli requires; on a plain Buster install I had to install dm-multipath and the device mapper libraries and tools before serverutilcli would find the arrays; but it ran just like it did on CentOS 8 (and 7). I haven't decided whether to stay on Debian or not; too early to tell. I have time to test and evaluate. My CentOS 7 installs aren't goin anywhere, though, at least until late 2023. And I've registered for a Developer subscription of RHEL so that I can properly evaluate that option, too. This is the beauty of open source: we have OPTIONS.

What to do when a selinux policy doesn't work?
by hw 14 Apr '21

14 Apr '21

Hi, I'm getting log file entries about ejabberd not being able to remove files that were uploaded by client through the file upload facility of XMPP. With the help of audit2allow, I have already created and installed some selinux modules to solve such issues, and still files can't be expired. So I used grep '/srv/data/ejabberd' /var/log/audit/audit.log | audit2allow -w to find out what might cause this, and the answer is: type=AVC msg=audit(1606302910.314:2905): avc: denied { open } for pid=18687 comm="8_dirty_io_sche" path="/srv/data/ejabberd/[...]" dev="md100" ino=166 scontext=system_u:system_r:ejabberd_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 Was caused by: Unknown - would be allowed by active policy Possible mismatch between this policy and the one under which the audit message was generated. Possible mismatch between current in-memory boolean settings vs. permanent ones. I have reloaded the policies with 'semodule -R', and that didn't change anything. The files in question seem to have the correct attributes like: ls -laZ /srv/data/ejabberd/[...] -rw-r--r--. 1 ejabberd ejabberd system_u:object_r:var_t:s0 1384362 Nov 25 12:15 /srv/data/ejabberd/[...] Ejabberd is supposed to expire files when they are older than desired, and selinux prevents it. How can I solve this problem other than by disabling selinux or by deleting the files manually?

bash: return status of an assignment
by Kenneth Porter 28 Feb '21

28 Feb '21

In the sqm-scripts package for managing network traffic shaping is this line for finding a program suitable for loading the kernel shaping modules: [ -z "$INSMOD" ] && INSMOD=$(which modprobe) || INSMOD=$(which insmod) It seems to set INSMOD to /usr/sbin/insmod, even though /usr/sbin/modprobe is available. (Both are symlinks to ../bin/kmod.) According to this article, the return value of the first assignment should be success and it shouldn't take the fallback statement: <https://unix.stackexchange.com/questions/270828/how-is-the-return-status-of…> Also working the issue here: <https://github.com/tohojo/sqm-scripts/issues/133>

How to install XFCE on CentOS 8?

Hi, Is anyone here running XFCE desktop on CentOS 8? If so, how did you install it? I just tried to install it from EPEL and this is what I got: # dnf group install Xfce Last metadata expiration check: 0:14:01 ago on Thu 11 Feb 2021 10:05:47 CET. No match for group package "NetworkManager-gnome" No match for group package "thunar-archive-plugin" I'm unable to find packages for NetworkManager-gnome or thunar-archive-plugin anywhere in CentOS 8 or EPEL 8. Did I miss something? Thanks, Simon

menu apps like make menu config
by Christopher Wensink 26 Feb '21

26 Feb '21

Good morning everyone, While vi, cat more or less can work (see what I did there..) for looking at every day Linux Administration, sometimes I think it's just easier to work with a menu based interface, where you can select and navigate messages and options, with a little bit of color, possibly function key interaction, and a working interface, similar to using make menuconfig for compiling the kernel and similar to performing a legacy text based install on a new system. Is there a master list of those kinds of apps that have a menu for looking at various things? Can anyone who thinks of more of these apps rattle off some other options such as: abc - for reading logs xyz for text based chat def - for a menu based browser ghi - for a text mail client, etc -- Christopher Wensink IS Administrator Five Star Plastics, Inc 1339 Continental Drive Eau Claire, WI 54701 Office: 715-831-1682 Mobile: 715-563-3112 Fax: 715-831-6075 cwensink(a)five-star-plastics.com www.five-star-plastics.com

OpenStack Training Recommendations
by Paul Heinlein 25 Feb '21

25 Feb '21

Our team at work is looking for OpenStack training options. The training should cover * overview of widely used OpenStack services * network architecture * installation and configuration * ongoing administration, maintenance, and troubleshooting * upgrading We'd prefer workflows based around Puppet or Ansible, since we know those tools, but operational continuity is more important than the tools used. We'd likewise prefer solutions oriented toward CentOS or RHEL, but, again, it's just a preference. We've investigated kolla-ansible for deployment, but we're not adverse to changing toolsets if the upside is right. I'd characterize our team as journeymen to expert system administrators. We specialize in supporting research groups. The training would be to provide skills and knowledge for our team to support OpenStack as a long-term in-house virtualization option. I'd love to hear your first-hand experiences with any specific training offerings. Thanks! (Note: we have other virtualization solutions in place. OpenStack is specifically required by researchers whose wider scientific communities have built workflows for that environment. Suggestions to ditch OpenStack for OtherGreatSolution will be ignored.) -- Paul Heinlein heinlein(a)madboa.com 45°38' N, 122°6' W

18 Feb '21

SO from the man page on date I can do current=`TZ=":America/Indianapolis" date` echo $current current=`TZ=":America/Los_Angeles" date ` echo $current And I get correct data. LA is 3 hours earlier. But doing this: current=`TZ=":America/Indianapolis" date +%s` echo $current current=`TZ=":America/Los_Angeles" date +%s` echo $current I get the same data - its not 3 hours different. What am I not doing correct ? Thanks, Jerry

by H 15 Feb '21

15 Feb '21

I have updated php on a Centos 7 system to use php 7.2 from sclo. Apache running on the system is also using php 7.2 as shown by phpinfo(), however, apache continues to use the default version of php, ie 5.4.16, when that user launches a process from the command line. All other users default to php 7.2 when running from the command line which is correct. For some reason I have missed configuring apache php-cli correctly. I have googled and found many examples on how to change the configuration settings so that apache uses php 7.2 when serving web pages but in this case it is php-cli that needs to be corrected to use a later version. What should I check? What have I missed? By the way, I am not planning to remove php 5.4 from the system since it might be needed for something at a later time. Thanks.

CentOS 7, selinux and pop_port_t
by H 12 Feb '21

12 Feb '21

I am muddling my way through learning selinux when installing a webapp with httpd as the webserver running CentOS 7. The app allows the user to send/receive mail etc but it seems that I have yet to allow access to imap port 993. So far it seems this is configured through pop_port_t but setsebool httpd_can_network_connect 1 does not include pop_port_t. In the audit log I have: type=AVC msg=audit(1613093671.415:155086): avc: denied { name_connect } for pid=22431 comm="httpd" dest=993 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:pop_port_t:s0 tclass=tcp_socket permissive=0 Yet, running the below sesearch -A -s httpd_t -c tcp_socket -p name_connect -d -C tells me ET allow httpd_t pop_port_t : tcp_socket name_connect ; [ httpd_can_sendmail ] I am obviously missing something. Does anyone know how to enable access to pop_port_t?

Update - Resizing a QEMU guest display

Strahil Nikolov and I took this conversation off-line for a few days. The thread of our discussion is below. Net result: No solution is yet found. Strahil had some very good ideas, but they did not pan out in this case. For archiving - and in hope that someone may have some other ideas! - I post this back to the list. -- Bill Gee ---------- Forwarded Message ---------- Subject: Re: [CentOS] Resizing a QEMU guest display Date: Tuesday, February 9, 2021, 10:38:08 PM CST From: Strahil Nikolov <hunter86_bg(a)yahoo.com> To: bgee(a)campercaver.net, Bill Gee <bgee(a)campercaver.net> Erm... mine was spice-vdagent.service , and not '.socket'.Never mind, it could be something else.

I am not familiar with any remote access application called "spice". I have tried two methods of accessing the host. First is to open it from the Virtual Machine Manager on the host. Second is to use TigerVNC to access it across the local network. > > > > > > > > > > > > > > > > I see a package installed on the guest which looks like the guest agent. Is there more that needs to be added? This is the only qemu package installed on both the Fedora machine that does not resize and the CentOS7 machine that will resize. The versions are way different between the two guests. > > > > > > > > > > > > > > > > [root@practice21a ~]# rpm -qa | grep qemu > > > > > > > > qemu-guest-agent-5.1.0-9.fc33.x86_64 > > > > > > > > > > > > > > > > The Fedora guest has, as you see, version 5.1.0-9. The CentOS7 guest has version 2.12.0-3. Perhaps the Fedora guest version is too new to run on a CentOS7 host?? > > > > > > > > > > > > > > > > I see other QEMU packages available. One of them is called "qemu-device-display-qxl" which is very suggestive. However, that package is NOT installed on the CentOS7 guest and yet that guest works. > > > > > > > > > > > > > > > > Another package I see is "libvirt-daemon-driver-qemu".
