KVM issue
by John R Pierce 16 Jun '16

16 Jun '16

running centos 6... have had a KVM linux vm (also C6) going for quite awhile that depends on a USB device mapping (a external audio DAC module). I updated the host today (yum update), it had been awhile (was like 6.5 before, now its 6.8+), and rebooted. the VM won't restart. when I try and restart it, I get this Error restoring domain: internal error Did not find USB device 8bb:2704 bus:5 device:4 Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 44, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 65, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1125, in startup self._backend.create() File "/usr/lib64/python2.6/site-packages/libvirt.py", line 686, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Did not find USB device 8bb:2704 bus:5 device:4 using virsh edit mydomain, I see... <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x08bb'/> <product id='0x2704'/> </source> </hostdev> and on the host, lsusb shows... # lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 002: ID 08bb:2704 Texas Instruments Audio Codec note the TI Audio device is bus 5, dev 2. Why is KVM insisting its bus 5 dev 4? I've deleted the device from the VM and tried to start it, same error. i've looked in every kvm/qemu related conf file I can find, no sign of bus 5 dev 4. # virsh start mydomain error: Failed to start domain mydomain error: internal error Did not find USB device 8bb:2704 bus:5 device:4 how can I fix this? -- john r pierce, recycling bits in santa cruz

Unable to mount a USB DVD drive
by Benjamin Smith 16 Jun '16

16 Jun '16

I can't seem to get an external DVD drive to show up on an CentOS 7 server. Wondering if it's just missing a driver or if I'm missing something fundamental. It's an external USB device that works fine on my Fedora 21 Laptop, but I never get a /dev/ entry (EG: /dev/sr0) on the server. What can I do to make this thing work?

scp via another server
by H 14 Jun '16

14 Jun '16

I normally use ssh to log into a remote server, change directory and then use scp from there to copy files from another remote server to the first one. Now the first server has been hit by continuous error correction messages from the ECC controller, all of which are corrected, and I am unable to get a command line to issue the required commands to change directory and then run scp from the other server. I have no problems, however, getting into the first server - except for being drowned by the error correction messages and the server seems to be running "fine". Until I am able to get to the server and investigate, is it possible to accomplish the above on a single command line, thus avoiding seeing the error messages? I should add that both the first and second server are set up to accept keys and not passwords so at least I don't have to worry about that. Thank you.

Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
by Kelly Lesperance 14 Jun '16

14 Jun '16

I’ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it. We have a cluster of 23 HP DL380p Gen8 hosts running Kafka. Basic specs: 2x E5-2650 128 GB RAM 12 x 4 TB 7200 RPM SATA drives connected to an HP H220 HBA Dual port 10 GB NIC The drives are configured as one large RAID-10 volume with mdadm, filesystem is XFS. The OS is not installed on the drive - we PXE boot a CentOS image we've built with minimal packages installed, and do the OS configuration via puppet. Originally, the hosts were running CentOS 6.5, with Kafka 0.8.1, without issue. We recently upgraded to CentOS 7.2 and Kafka 0.9, and that's when the trouble started. What we're seeing is that when the weekly raid-check script executes, performance nose dives, and I/O wait skyrockets. The raid check starts out fairly fast (20000K/sec - the limit that's been set), but then quickly drops down to about 4000K/Sec. dev.raid.speed sysctls are at the defaults: dev.raid.speed_limit_max = 200000 dev.raid.speed_limit_min = 1000 Here's 10 seconds of iostat output, which illustrates the issue: [root@r1k1log] # iostat 1 10 Linux 3.10.0-327.18.2.el7.x86_64 (r1k1) 05/24/16 _x86_64_ (32 CPU)

scheduler, queue_depth, queue_type, read-ahead, etc, but nothing has helped. We've also upgraded all of the firmware, and installed HP's mpt2sas driver. We have 4 other Kafka clusters, however they're HP DL180 G6 servers. We completed the same CentOS 6.5 -> 7.2/Kafka 0.8 -> 0.9 upgrade on those clusters, and there has been no impact to their performance. We've been banging our heads against the wall for a few weeks now, really hoping someone from the community can point us in the right direction. Thanks, Kelly Lesperance

HFSPlus Question
by Albert McCann 12 Jun '16

12 Jun '16

In CentOS 7.2.1511 does the 3.10.0-327.18.2.el7.centos.plus.x86_64 (Plus) kernel read HFSPlus iMac drives? I don't see any hfsplus modules installed anywhere, so I suspect not. My sister's 17" iMac died, and I'm trying to recover the drive. If it spins up, I'd like to copy it with dd. I see that Elrepo has kmod-hfsplus and hfsplus-tools, will these work with the Plus kernel? I still have to pull the drive from that infernal iMac case, so can't test yet. Thank you for any clues, my Google-foo isn't finding anything on the Plus kernel and HFSPlus. --- I yam Popeye of the Borg. Prepares ta beez askimiligrated.

setting up auto logout in CentOS 6
by Vanhorn, Mike 09 Jun '16

09 Jun '16

I would like to have my lab workstations logout a session after the person has been idle for a certain period of time. After some searching on the web, I got into /etc/gconf/schemas/gnome-session.schemas and set the default value of max_idle_action to “forced-logout”: <schema> <key>/schemas/desktop/gnome/session/max_idle_action</key> <applyto>/desktop/gnome/session/max_idle_action</applyto> <owner>gnome</owner> <type>string</type> <default>forced-logout</default> <gettext_domain>gnome-session-2.0</gettext_domain> <locale name="C"> <short>The action to take after the maximum idle time</short> <long>The name of the action to take when the maximum allowed idle time has been reached. The Delay is specified in the "max_idle_time" key. Allowed values are: logout, forced-logout. An empty string disables the action.</long> </locale> </schema> but the system is not logging me out after the max_idle_time. Is there something I’m missing? Thanks! --- Mike VanHorn Senior Computer Systems Administrator College of Engineering and Computer Science Wright State University 265 Russ Engineering Center 937-775-5157 michael.vanhorn(a)wright.edu
