Confgure SAN with Linux
by MARMEY Cyril 06 Oct '11

06 Oct '11

Hi, i'm new to this subject. I try to present a san attachment on my Linux server (OEL 5.5). I'm running a HP server with qlogic 2462 and my SAN Storage is a HP EVA. Zoning is good. I installed HP SanSurfer and i see the vdisk with this utility. But, impossible to see the volume from the os. Fdisk returns me to the local disks, and multipath -l command does not return any info. I installed qlogic drivers, edit multipah.conf, install devicee mapper .... Have you any idea or how to ? I hope I was clear, I started with Linux and I can not put all the necessary information. Thank's for your help Best regards ________________________________ Ce message et toutes les pi?ces jointes sont ?tablis ? l'intention exclusive de ses destinataires et sont confidentiels.

guest vms crash host systems
by Negative 06 Oct '11

06 Oct '11

I built guest vm's one for Windows 7 and one for Windows XP using the virtual machine manager on a just updated to centos 5.7, and they are both crashing the host machine. They run only for a few minutes, but suddenly freeze, crashing the host. There is no networking. No X. No way to drop out of X. The only way out is a hard reboot. I don't see anything in the logs -- messages or libvirt logs -- immediately before the crash. I haven't found anything like this on the web or on this list. The workstation has two xeon E5410s. I noticed that both the kvm-amd and kvm-intel modules are loaded, but don't know if that would cause a problem. I had an ati firepro graphics card in the machine, but suspected that might be the source of some conflict, and I put in an Nvidia card. The vm's were built with all the defaults. The configuration is just about identical to vms I have running on a smaller machine with a dual core Athalon. Thanks for any suggestions.

CentOS 6 USB changes
by m.roth＠5-cent.us 05 Oct '11

05 Oct '11

Ok, I just managed, after much effort, to rebuild my USB key to install CentOS 6. There are a number of changes. Partition the USB key, but make partition 1, Win 95 (FAT32) (I think that's partition type "b"), bigger. I made it 500M. The rest should be ext3 (or whatever). Format the partitions. Make sure to toggle the bootable flag on partition 1. syslinux /dev/<DOS partition> When you're done, the DOS partition should look like this: ls -laF /mnt /boot/ /ldlinux.sys /syslinux/ Under /boot is /grub, and it's contents. Make sure you create a grub.conf to put in there. If syslinux didn't put it there, mount your .iso, and copy /mnt/iso/isolinux into there, then rename /syslinux/isolinus.cfg to /syslinux/syslinux.cfg. I put a grub.conf here, too: cat /mnt/disk/syslinux/grub.conf #debug --graphics default=0 splashimage=@SPLASHPATH@ timeout 5 hiddenmenu title @PRODUCT@ @VERSION@ kernel @KERNELPATH@ initrd @INITRDPATH@ title Install system with basic video driver kernel @KERNELPATH@ xdriver=vesa nomodeset askmethod initrd @INITRDPATH@ title rescue kernel @KERNELPATH@ rescue askmethod initrd @INITRDPATH@ On the second partition, copy your .iso images. Then copy /mnt/iso/images there. You should be good to go. NOTE: during the install, if you make any partitions encrypted, it will hang when it's done formatting, so reboot, and tell it to install again, and then not to format. It will start, then ask for the password, then actually go through the install. mark

by Wade Hampton 05 Oct '11

05 Oct '11

Anyone have any luck running updated Firefox on CentOS 5? We have CentOS 5 workstations and need to update their Firefox but it dumps core even when using the libstdc++ from Fedora 9. I would like anything stable and secure beyond Firefox 3 but can't find tarballs for anything other than 7.0.1. CentOS 5.5 i386 w/ updates firefox-7.0.1.tar.bz2 libstdc++-4.3.0-8.i386.rpm from Fedora 9 Thanks, -- Wade Hampton

Howto use Gmail with sendmail on CentOS 6
by Alexander Farber 05 Oct '11

05 Oct '11

Hello, I hope nobody minds, if I post a short summary here for archives - How to forward mails via Gmail account from CentOS 6 (I use sendmail, because haven't figured out how to setup Postfix yet): # yum erase postfix # yum install sendmail sendmail-cf cyrus-sasl-plain cyrus-sasl-md5 # mkdir /etc/mail/auth # chmod 700 /etc/mail/auth Create the file /etc/mail/auth/client-info: AuthInfo:smtp.gmail.com "U:smmsp" "I:your_gmail_address" "P:your_password" "M:PLAIN" AuthInfo:smtp.gmail.com:587 "U:smmsp" "I:your_gmail_address" "P:your_password" "M:PLAIN" # cd /etc/mail/auth # makemap -r hash client-info.db < client-info # chmod 600 client-info client-info.db Then edit /etc/mail/sendmail.mc (most lines are there already and just need to be uncommented and edited a bit): define(`SMART_HOST', `smtp.gmail.com')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl define(`confCACERT_PATH', `/etc/pki/tls/certs')dnl define(`confCACERT', `/etc/pki/tls/certs/ca-bundle.crt')dnl define(`confSERVER_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confSERVER_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confCLIENT_CERT', `/etc/pki/tls/certs/sendmail.pem')dnl define(`confCLIENT_KEY', `/etc/pki/tls/certs/sendmail.pem')dnl Then create certificates (I've used "DE", "NRW", "Bochum", "my hostname", "my gmail address" there as input): # cd /etc/pki/tls/certs # make sendmail.pem Append the following line to /etc/aliases: root: your_gmail_address and run "newaliases". If you need, also append "apache" to /etc/mail/trusted-users. Finally: # cd /etc/mail # make (this will generate new sendmail.cf) # service sendmail restart and check the /var/log/maillog for error messages while sending test mail messages from command line.

postmap: fatal: open database /etc/postfix/sasl_passwd.db: Permission denied
by Alexander Farber 05 Oct '11

05 Oct '11

I'm trying to configure mail forwarding through Gmail on CentOS 6 with postfix, following the blog http://carlton.oriley.net/blog/?p=31 and I think the blog has missed the step: # postmap /etc/postfix/sasl_passwd - as I've seen in the /var/log/maillog: postfix/smtp[1926]: fatal: open database /etc/postfix/sasl_passwd.db: No such file or directory postfix/master[1831]: warning: process /usr/libexec/postfix/smtp pid 1926 exit status 1 postfix/master[1831]: warning: /usr/libexec/postfix/smtp: bad command startup -- throttling But when I try to run postmap, I get postmap: fatal: open database /etc/postfix/sasl_passwd.db: Permission denied even though the postfix service is stopped, the SELinux is permissive and the file is writable: [root@preferans postfix]# ll -rw-r--r--. 1 root root 20K Jun 25 14:50 access -rw-r--r--. 1 root root 12K Jun 25 14:50 canonical -rw-r--r--. 1 root root 9.7K Jun 25 14:50 generic -rw-r--r--. 1 root root 18K Jun 25 14:50 header_checks -rw-r--r--. 1 root root 27K Oct 4 20:24 main.cf -rw-r--r--. 1 root root 27K Oct 4 20:23 main.cf.OLD -rw-r--r--. 1 root root 5.0K Jun 25 14:50 master.cf -rw-r--r--. 1 root root 6.7K Jun 25 14:50 relocated -rw-r--r--. 1 postfix root 113 Oct 4 20:25 sasl_passwd -rw-r--r--. 1 root root 13K Jun 25 14:50 transport -rw-r--r--. 1 root root 13K Jun 25 14:50 virtual Has anybody fought this problem already?

Problems with Intel Ethernet and module e1000e
by Volker Poplawski 04 Oct '11

04 Oct '11

Hi all, I'm facing a serious problem with the e100e kernel module for Intel 82574L gigabit nics on Centos 6. The device eth0 suddenly stops working i.e. no more networking. When I do ifconfig from console I get eth0 Link encap:Ethernet HWaddr 00:xx:xx:xx:xx:EA inet6 addr: fe80::225:90ff:fe50:8fea/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:37984 errors:54245436935850 dropped:9040906155975 overruns:0 frame:36163624623900 TX packets:20884 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4431149 (4.2 MiB) TX bytes:4628666 (4.4 MiB) Memory:fb900000-fb920000 Reported byte count and RX TX packet count is reasonable. Howerver the incredible large number of errors is not. Also they don't pile up but simply appear when the device stopped working. In /var/log/messages I get: Sep 23 12:21:09 wader2 kernel: ------------[ cut here ]------------ Sep 23 12:21:09 wader2 kernel: WARNING: at net/sched/sch_generic.c:261 dev_watchdog+0x26d/0x280() (Not tainted) Sep 23 12:21:09 wader2 kernel: Hardware name: X9SCL/X9SCM Sep 23 12:21:09 wader2 kernel: NETDEV WATCHDOG: eth0 (e1000e): transmit queue 0 timed out Sep 23 12:21:09 wader2 kernel: Modules linked in: tun ebtable_nat ebtables xt_CHECKSUM iptable_mangle ipt_MASQUERADE iptable_nat nf_nat sunrpc bridge stp llc xt_physdev ipt_REJECT nf_conntrack_ipv4 nf_defrag_ipv4 iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 kvm_intel kvm serio_raw i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support sg e1000e ext4 mbcache jbd2 sd_mod crc_t10dif ahci megaraid_sas dm_mod [last unloaded: scsi_wait_scan] Sep 23 12:21:09 wader2 kernel: Pid: 0, comm: swapper Not tainted 2.6.32-71.29.1.el6.x86_64 #1 Sep 23 12:21:09 wader2 kernel: Call Trace: Sep 23 12:21:09 wader2 kernel: <IRQ> [<ffffffff8106b947>] warn_slowpath_common+0x87/0xc0 Sep 23 12:21:09 wader2 kernel: [<ffffffff8106ba36>] warn_slowpath_fmt+0x46/0x50 Sep 23 12:21:09 wader2 kernel: [<ffffffff8142a07d>] dev_watchdog+0x26d/0x280 Sep 23 12:21:09 wader2 kernel: [<ffffffff8107d3c5>] ? internal_add_timer+0xb5/0x110 Sep 23 12:21:09 wader2 kernel: [<ffffffff81429e10>] ? dev_watchdog+0x0/0x280 Sep 23 12:21:09 wader2 kernel: [<ffffffff8107dfc7>] run_timer_softirq+0x197/0x340 Sep 23 12:21:09 wader2 kernel: [<ffffffff810a0e90>] ? tick_sched_timer+0x0/0xc0 Sep 23 12:21:09 wader2 kernel: [<ffffffff8102f52d>] ? lapic_next_event+0x1d/0x30 Sep 23 12:21:09 wader2 kernel: [<ffffffff81073d67>] __do_softirq+0xb7/0x1e0 Sep 23 12:21:09 wader2 kernel: [<ffffffff81095c50>] ? hrtimer_interrupt+0x140/0x250 Sep 23 12:21:09 wader2 kernel: [<ffffffff810142cc>] call_softirq+0x1c/0x30 Sep 23 12:21:09 wader2 kernel: [<ffffffff81015f35>] do_softirq+0x65/0xa0 Sep 23 12:21:09 wader2 kernel: [<ffffffff81073b65>] irq_exit+0x85/0x90 Sep 23 12:21:09 wader2 kernel: [<ffffffff814d0a31>] smp_apic_timer_interrupt+0x71/0x9c Sep 23 12:21:09 wader2 kernel: [<ffffffff81013c93>] apic_timer_interrupt+0x13/0x20 Sep 23 12:21:09 wader2 kernel: <EOI> [<ffffffff812dac0f>] ? acpi_idle_enter_bm+0x28f/0x2c3 Sep 23 12:21:09 wader2 kernel: [<ffffffff812dac08>] ? acpi_idle_enter_bm+0x288/0x2c3 Sep 23 12:21:09 wader2 kernel: [<ffffffff813df687>] cpuidle_idle_call+0xa7/0x140 Sep 23 12:21:09 wader2 kernel: [<ffffffff81011e96>] cpu_idle+0xb6/0x110 Sep 23 12:21:09 wader2 kernel: [<ffffffff814b1a0a>] rest_init+0x7a/0x80 Sep 23 12:21:09 wader2 kernel: [<ffffffff818c3f19>] start_kernel+0x413/0x41f Sep 23 12:21:09 wader2 kernel: [<ffffffff818c333a>] x86_64_start_reservations+0x125/0x129 Sep 23 12:21:09 wader2 kernel: [<ffffffff818c3438>] x86_64_start_kernel+0xfa/0x109 Sep 23 12:21:09 wader2 kernel: ---[ end trace 69b6c5e494cffe4d ]--- Sep 23 12:21:10 wader2 kernel: 0000:04:00.0: eth0: Error reading PHY register Sep 23 12:21:10 wader2 kernel: e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX The last line falsely reports the link to be 1000Mbit but it is actually 100Mbit. Same does ethtool. Bringing down the interface with ifconfig eth0 down and then ifconfig eth0 up does not help. A reboot gets the interface back to normal. The problem returns after some minutes, hours or a day. Any ideas? Regards .......Volker

Expunge Old Email
by John Hinton 04 Oct '11

04 Oct '11

For those of you running mailservers on CentOS 6, what are the suggestions for programs to expunge old email? For instance, deleting email from a Spam folder that is 2 weeks old or older. I see that Dovecot does have a solution, but was wondering about what others have landed on. My systems are basically Postfix, Dovecot using Maildir. Thanks, John Hinton

CentOS 6: Increase shared memory limits permanently
by Alexander Farber 04 Oct '11

04 Oct '11

Hello again, on CentOS 6 / 64 bit what is please the best way to permanently increase the shared memory? I'd like to give shared_buffers = 4096MB to PostgreSQL 8.4 on my machine with 16 GB RAM, but I currently only have: # sysctl -A|grep shm kernel.shmmax = 33554432 kernel.shmall = 2097152 kernel.shmmni = 4096 and this produces the error in /var/lib/pgsql/pgstartup.log: FATAL: could not create shared memory segment: Invalid argument DETAIL: Failed system call was shmget(key=5432001, size=4399202304, 03600). HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMMAX parameter. You can either reduce the request size or reconfigure the kernel with larger SHMMAX. To reduce the request size (currently 4399202304 bytes), reduce PostgreSQL's shared_buffers parameter (currently 524288) and/or its max_connections parameter (currently 103). If the request size is already small, it's possible that it is less than your kernel's SHMMIN parameter, in which case raising the request size or reconfiguring SHMMIN is called for. The PostgreSQL documentation contains more information about shared memory configuration. And I wonder if I should set shmmax or shmall and also if these 2 limits are total for all machine processes or per process? (i.e. should I allow a bit more for processes besides PostgreSQL)? Thank you Alex
