lapack
by Michael Hennebry 31 Dec '19

31 Dec '19

Has anyone gotten lapack to work on centos 7? If so, how? Most recently, I installed lapace-devel and let yum bring in what it wanted. Whenever I try to link, I get a long list of undefined references ending with /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/liblapacke.so: undefined reference to `dgeevx_' [hennebry@localhost test]$ nm -D /usr/lib64/libblas.so | grep dge 0000000000018850 T dgemm_ 0000000000011080 T dgemv_ 00000000000170c0 T dger_ [hennebry@localhost test]$ confirmes that the reference is not there. Installing blas or atlas first does not help. When installing lapack-devel, yum always wants to install blas-devel. What do I need? -- Michael hennebry(a)web.cs.ndsu.NoDak.edu "Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a heiroglyph, and the blood of a virgin." -- someeecards

cannot install Centos 8 Stream
by Paul de Vries 30 Dec '19

30 Dec '19

I want to install Centos Stream on an older server. the Areca ARC-1680 RAID Controller is not supported anymore, so I tried to install on an external USB drive. i did a manual partitioning: sdc1 /boot/efi efi system partition sdc2 /boot ext4 sdc3 / lvm and the system cannot boot - hangs forever. new try: sdc1 /boot/efi, efi system partition sdc2 / xfs at end of install i see 'bootloader install failed'. debug shows 'NOTICE root:83haiku: debug: /dev/sdc1 is not a beFS partiotion: exiting' then i did an automatic partitioning and got no efi partition. and the system cannot boot - hangs forever. HOW do i install centos stream on external usb disk with efi boot?

Does Centos kernel support usb w/ UASP ?
by Fred Smith 30 Dec '19

30 Dec '19

Looking to buy a new usb-attached RAID box for nightly backups, and I see that many of them now support usb 3.1 with UASP. Looking at add-in usb 3.1 cards (my motherboard is probably too old, and only supports usb 3.0) to go with it, but don't know if the old kernel RH/Centos uses supports UASP. Chipset dependent? If one can trust the product images on Amazon, most of them use an asmedia 2142 chip. Anyone know? Thanks in advance!

Install Questions
by Eugene Poole 29 Dec '19

29 Dec '19

This is my situation: I've a AMD Phenom II X6 1055T machine with 2 - ISA DVD drives and 6 - SATA Drives. The drives are (I assume by the BIOS) assigned /dev/ sda through /dev/sdf. In order to do a specific definition easily I use CentOS 6 (what disks are used with RAID-1 and which ones are used with RAID-10) and what the /dev/mdx names to use. What I don't understand is why when I get to the page where I'm to install the boot loader it wants to install it on /dev/sdf. When I try to install it on /dev/md0 (where /boot is located) the reboot fails. When I try to alter the BIOS order (it allows me to do this with 4 of the 6 disks) so the /dev/sda is the first BIOS drive the also fails. Before I had multiple disks in a RAID environment I could install the boot loader on /dev/sda1 without problems (BTW, /dev/md0 is defined with /dev/sda1 and /dev/sdd1). What am I doing wrong and how can I make it better? BTW, My goal is to get the file system defined exactly like I want it and then install CentOS 7.5 (CentOS 7.7 gives me several warning messages concerning my processor).

Centos 8 KVM and Win10 time
by Tom Bishop 28 Dec '19

28 Dec '19

I didn't have this issue when using Centos 7 but for some reason now using 8 I have a windows 10 vm that keeps changing it's time to UTC. Centos appears to be using local time but something is telling it to change time. I have time sync running in windows and it syncs but then at some point when I come back to it the time has changed. Tried a bunch of things but so far no luck, anyone have any suggestions that I could try please let me know, thanks.

The case of the missing /boot/grub2/grub.cfg in centos8
by Mauricio Tavares 28 Dec '19

28 Dec '19

So I installed centos8. And I was looking for the grub config file: [root@testbox ~]# ls -l /etc/grub2.cfg lrwxrwxrwx. 1 root root 22 Oct 2 13:01 /etc/grub2.cfg -> ../boot/grub2/grub.cfg [root@testbox ~]# But [root@testbox ~]# ls /boot/grub2/ grubenv [root@testbox ~]# Why is it not there? FYI, I did try 'yum reinstall grub2' and no /boot/grub2/grub.cfg for me.

Disabling TLS 1.1 in Centos 7 cockpit
by Erick Perez - Quadrian Enterprises 28 Dec '19

28 Dec '19

Hi, I'm using cockpit in standard port 9090 in a Centos 7 system. Due to a suggestion from management, they want TLS 1.1 disabled system-wide in all Linux boxes and TLS 1.2 enabled. I have not found proper documentation on how to disable it for cockpit (version 195.1 ships with Centos 7) So far I have tried (https://cockpit-project.org/guide/149/https.html): /usr/lib/systemd/system/cockpit.service [Service] Environment=G_TLS_GNUTLS_PRIORITY=-VERS-ALL:+VERS-TLS1.2 And I also created the file /etc/systemd/system/cockpit.service.d/ssl.conf and added: [Service] Environment=G_TLS_GNUTLS_PRIORITY=-VERS-ALL:+VERS-TLS1.2 after that, I systemctl restart cockpit But if I do #openssl s_client -connect localhost:9090 -tls1_1 I get a proper response (a certificate), so TLS 1.1 is being accepted. Suggestions? Thanks. -- --------------------- Erick Perez ---------------------

nfs causes Centos 7.7 system to hang
by Nikolaos Milas 27 Dec '19

27 Dec '19

Hello, MERRY CHRISTMAS to all in list! After I upgraded to latest: CentOS Linux release 7.7.1908 (Core) I am facing nfs crashes which cause the system to hang frequently. This is caused by cp to nfs-mounted shares. Below is dmesg output; you will see call traces. These cause system to gradually overload: [root@hesperia1 ~]# top top - 10:09:40 up 10:16, 1 user, load average: 53.66, 54.13, 52.98 Tasks: 475 total, 2 running, 436 sleeping, 0 stopped, 37 zombie %Cpu(s): 0.1 us, 0.6 sy, 0.0 ni, 99.2 id, 0.0 wa, 0.0 hi, 0.0 si, 0.1 st KiB Mem : 3879928 total, 813504 free, 1733216 used, 1333208 buff/cache KiB Swap: 4063228 total, 4062708 free, 520 used. 1797264 avail Mem and finally hangs showing messages (which I have not recorded precisely) in the CLI login screen like "System out of memory". Then I have to reboot. I tried to downgrade nfs-utils and rpcbind to earlier versions (in case there is a bug in latest ones), but I couldn't: [root@hesperia1 ~]# yum downgrade rpcbind-0.2.0-47 nfs-utils-1.3.0-61 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: ftp.ntua.gr * epel: mirrors.daticum.com * extras: ftp.ntua.gr * updates: ftp.ntua.gr No package rpcbind-0.2.0-47 available. No package nfs-utils-1.3.0-61 available. Error: Nothing to do Do you know if this is a known bug? (I couldn't find something in my searches.) Can you suggest a solution / workaround?
