grub To grub2 Migration
by Eugene Poole 21 Nov '17

21 Nov '17

I'm trying to move to CentOS 7. One of my concerns is how to make the changes to grub that supports booting from either of the disk partitions that make up /dev/md0 (/dev/sda1 and /dev/sdb1) or whatever it would be under CentOS 7. Is there some document or tutorial available on making the move from CentOS 6 to CentOS 7? -- Eugene Poole Woodstock, Georgia

CentOS Atomic and OpsWorks?

20 Nov '17

Has anyone used CentOS Atomic with OpsWorks? My searches on the internet haven't turned anything up, so I wanted to see if there was any experience/advice on here. Thanks, Dave

Hi Mark, did you manage to sort out messages from Dracut and /sbin/weak-modules you received while installing kmod-nvidia? We get the same messages while installing kmod-nvidia-384.98-1.el7_4.elrepo.x86_64 on RHEL 7.4 with the kernel 3.10.0-693.5.2.el7.x86_64. Kr, Jens

Intel Bluetooth problems - "Invalid request code (56)" - on CentOS 6.9
by Toralf Lund 20 Nov '17

20 Nov '17

Hi, I have Lenovo laptop with an Intel wireless and Bluetooth adapter, running CentOS 6.9. The wireless works just fine, but I can't seem to get Bluetooth to work. When I try to force it up from the command line I get # hciconfig hci0 up Can't init device hci0: Invalid request code (56) There is also a similar message message in /var/log/messages from start-up on boot. The device info from "hciconfig" also seems a bit suspicious to me - notice how the address has all 0s: # hciconfig -a hci0: Type: BR/EDR Bus: USB BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 DOWN RX bytes:48 acl:0 sco:0 events:8 errors:0 TX bytes:24 acl:0 sco:0 commands:12 errors:4 /var/log/messages indicates that firmware is loaded correctly # egrep "iwlwifi.*firmware" /var/log/messages Nov 20 09:24:16 osl-97214 kernel: iwlwifi 0000:04:00.0: firmware: requesting iwlwifi-8000C-17.ucode Nov 20 09:24:16 osl-97214 kernel: iwlwifi 0000:04:00.0: firmware: requesting iwlwifi-8000C-16.ucode Nov 20 09:24:16 osl-97214 kernel: iwlwifi 0000:04:00.0: loaded firmware version 16.242414.0 op_mode iwlmvm and I think the following shows that the device is actually there # lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 046d:c52b Logitech, Inc.

Possible to have EthX acting like the ipaddress of the attached device (aka bridge) having no ipaddress?
by Jobst Schmalenbach 20 Nov '17

20 Nov '17

Hi I have a Centos 6.X router/firewall/gateway for a /29 network all connected to one ETHX that has a switch behind it. This setup works very well but does NOT allow me to QOS one of the devices (a VOIP phone, many lines) as for "tc" to work I need a device, not ipaddress. I thought to connect the VOIP phone directly to the router, but in doing so I need that interface to ACT like the IPADDRESS of the VOIP box, meaning the ethernet interface has no ipaddress acting like a bridge: Internet | --------------------------- | router ip | | BRIDGE base of /29 --------------------------- | | | ------------- | | | | _____________ | | | | | | ---------------- | phone system | ---------------- That way I can use "tc" to prioritize the traffic for the phone system If there are other ways to do this, please suggest. thanks Jobst -- Sometimes, the sharpest sword is not enough, but usually...it is. | |0| | Jobst Schmalenbach | | |0| +61 3 9533 0000, POBox 277, Caulfield South, 3162, Australia |0|0|0|

CentOS 7: unable to mount
by wwp 18 Nov '17

18 Nov '17

Hello, when I plug an external disk (USB3) of mine, I get this 'Unable to mount /mnt/storage10' alert: Error mounting system-managed device /dev/sda1: Command-line `mount "/mnt/storage10"' exited with non-zero exit status 32: mount: /dev/sda1 is already mounted or /mnt/storage10 busy /dev/sda1 is already mounted on /mnt/storage10 And it's right, /mnt/storage10 has just been mounted (by root): # mount /dev/sda1 on /mnt/storage10 type ext4 (rw,nosuid,nodev,relatime,seclabel,data=ordered) as it's defined in /etc/fstab: /dev/disk/by-id/usb-TOSHIBA_External_USB_3.0_20140807009490F-0:0-part1 /mnt/storage10 auto nosuid,nodev,nofail,x-gvfs-show 0 0 Question is: why are there 2 concurrent mount attempts? The user one fails. I will need the root password to unmount. I'd prefer the user mount to proceed, BTW. Other USB disks behave the same here. For every single USB disk I need, once I've mounted it the first time, I've edited the mount options in the gnome-disk-utility and set it to be automatically mounted and "Mount at startup" and "Show in user interface" to true. Any hint, there? Regards, -- wwp

>> I can't seem to find apcupsd for C 6. Just went to epel's website, >> and not visible. Anyone have a clue? I am running apcupsd on CentOS 6.9, monitoring through the network a common UPS that is physically connected to another server via USB. Just download the latest source code and compile it yourself. It's as easy as ./configure make make install No problems whatsoever.
