what might cause iSCSI connection 1:0 error ISCSI_ERR_CONN_FAILED
by Götz Reinicke - IT Koordinator 10 Dec '12

10 Dec '12

Hi, I do have a centos 6.x server which accessed two different iscsistorages for a long time without any trouble. The storage-connection is done by a separate NIC and VLAN. The LAN access is on an other NIC. This weekend something broke and I don't have any clue what might be the problem or what caused it. The storages where mounted RO. In /var/loge/messages there are lot of messages; so from dmesg: Dec 10 17:13:21 richter kernel: connection3:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4324582419, last ping 4324587419, now 4324592419 Dec 10 17:13:21 richter kernel: connection3:0: detected conn error (1011) Dec 10 17:13:22 richter iscsid: Kernel reported iSCSI connection 3:0 error (1011 - ISCSI_ERR_CONN_FAILED: iSCSI connection failed) state (3) From dmesg: connection1:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4324597423, last ping 4324602423, now 4324607423 connection1:0: detected conn error (1011) I restarted the server and the filesystems are back online RW, but there are still that messages. Thanks for any suggestion or hint! Regards . Götz -- Götz Reinicke - IT-Koordinator - Filmakademie Baden-Württemberg GmbH

ionice...
by John Doe 10 Dec '12

10 Dec '12

Hey, anyone has some successful experience with ionice? I tried it with 'idle' (-c 3) parameter. When I did a quick test (find /), it seemed to work with frequent pauses (I guess waiting for idle). But when I used it on my big tar, it made it worse than without... which seems counter-intuitive. Thx, JD

centos 6.2_x86_64, get black screen with blinking cursor after select item from GRUM menu.
by yihect 09 Dec '12

09 Dec '12

Hi, all: I'm using centos 6.2-x86_64, the built-in kernel version is 2.6.32-220.el6.x86_64. Now I compiled kernel of version of linux-2.6.32-220.23.1.el6.x86_64, which get from kernel-2.6.32-220.23.1.el6.src.rpm. I have put vmlinuz and initramfs into /boot directory, as follow: [kdev@panda boot]$ ll /boot/vmlinuz-2.6.32-* ./initramfs-2.6.32-* -rwxr-xr-x. 1 root root 3938288 12月 7 2011 /boot/vmlinuz-2.6.32-220.el6.x86_64 -rw-r--r--. 1 root root 3952816 12月 8 19:23 /boot/vmlinuz-2.6.32-kdev-v1 -rw-r--r--. 1 root root 15888573 5月 26 2012 ./initramfs-2.6.32-220.el6.x86_64.img -rw-r--r--. 1 root root 15824301 12月 8 20:17 ./initramfs-2.6.32-kdev-v1 and modified grub.conf like this: #boot=/dev/sdb default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS62 (2.6.32-220.el6.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-220.el6.x86_64 ro root=UUID=f09cc6eb-99fa-4c90-a1a5-ad15277e8331 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM initrd /initramfs-2.6.32-220.el6.x86_64.img title CentOS62 (2.6.32-kdev-v1) root (hd0,0) kernel /vmlinuz-2.6.32-kdev-v1 ro root=UUID=f09cc6eb-99fa-4c90-a1a5-ad15277e8331 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM initrd /initramfs-2.6.32-kdev-v1.img what i do is just copy the original section which beginning with title, and then modified it with different version_string. But at last, after selecting the kdev-v1 item from grub's menu, i got a black screen with a cursor blinking in the top-left, and paused there. If i select the original kernel, namely 2.6.32-220.el6.x86_64, all thing is correct. Is the GRUB gets wrong?? My machine is : motherboard: MSI G41M-P26 cpu: Intel Celeron(R) CPU E3400 Thanks ~~!!

Questions on making a kickstart cfg
by Robert Moskowitz 07 Dec '12

07 Dec '12

So I took the anaconda cfg, commented out the partition/disk pieces and ran it off my repo server and it almost worked. Little things like not including things I had done on network setup. No first boot.... :) So now I am reading up on building a kickstart cfg http://wiki.centos.org/TipsAndTricks/KickStart http://www.centos.org/docs/5/html/5.2/Installation_Guide/s1-kickstart2-howu… So for starters I figured out that the lines prior to the %packages are commands. So I added there: firstboot --enable Oh, but this won't work if firstboot is not installed. I am tempted to assume it will be, as it was from all the packages that got installed in the installation that created this anaconda-ks.cfg. Sounds reasonable? To NOT use firstboot, what do I have to add to the kickstart beyond user --name=something --password=somethingstrong Of course if I don't have the encrypt stuff, this is a first use password that I would change on first login. But what about time setup? And what else is there in firstboot? Then I want some network setup, so I changed to network line from: network --onboot yes --device eth0 --bootproto dhcp --noipv6 to network --onboot yes --device eth0 --bootproto=query I note that anaconda had "--bootproto dhcp" while the howto shows an = , I assume both forms are valid? Oh, is there a 'bug' in the network section of the howto? =================================== The line for static networking is more complex, as you must include all network configuration information on one line. You must specify the IP address, netmask, gateway, and nameserver. For example: (the "\" indicates that this should be read as one continuous line): network --bootproto=static --ip=10.0.2.15 --netmask=255.255.255.0 \ --gateway=10.0.2.254 --nameserver=10.0.2.1 If you use the static method, be aware of the following two restrictions: All static networking configuration information must be specified on one line; you cannot wrap lines using a backslash, for example. =================================== Wait a sec, their example uses the \ and then it says you can't use the \? Which is it?

Nautilus "Open With" difference with "Connect to server..." sftp
by Rob Townley 07 Dec '12

07 Dec '12

.PDFs on my local harddrive open by default with acroread Adobe Reader 9. .PDFs on network shares open with evince Document Viewer. Is there some way to force "Open With" to also use acroread for network locations as well? Here are the inconsistencies in the UI: When right clicking a local harddrive .PDF, top line in menu is "Open with Adobe Reader 9" When right clicking a remote harddrive .PDF, top line in menu is "Open with Document Viewer" When right clicking and choosing properties and choosing the "Open With" tab, a .PDF file in both locations indicates "Adobe Reader 9." gdm on CentOS 6.3 32bit with all latest updates.

AMD Liano A8 Processors supported on CentOS 6.x?
by Ljubomir Ljubojevic 07 Dec '12

07 Dec '12

Hi. Red Hat is saying that AMD Liano A8 CPU's are not supported by RHEL/CentOS 6: https://access.redhat.com/knowledge/articles/65431 Is that true? What can I expect if I try to install CentOS 6.3 on PC with that CPU? -- Ljubomir Ljubojevic (Love is in the Air) PL Computers Serbia, Europe Google is the Mother, Google is the Father, and traceroute is your trusty Spiderman...

/tmp directory
by Jerry Geis 07 Dec '12

07 Dec '12

Is there something that "automatically" removes files in the /tmp directory on a scheduled basis? Perhaps like at the start of the month or something. I am on CentOS 6? I had a number of files stored there and they are just gone. Very odd. Jerry
