Xen clock drift
by Jack Bailey 09 Jan '08

09 Jan '08

Hello All, Consider a CentOS-5.1 Xen server (2.6.18-53.1.4.el5xen) hosting two domains running CentOS-5.1 (2.6.18-53.1.4.el5). One domain has a fairly accurate clock, the other domain has a clock that gains ungodly amounts of time, roughly one minute every two or three minutes. For a fix, one suggestion is to run this command in DomU: echo 1 > /proc/sys/xen/independent_wallclock This didn't change anything. As an experiment, I wrote a script to call ntpd -q, sleep 60, and repeat indefinitely. Here are a couple of snippets of output: goodclock# ksh ./xenclockdrift ntpd: time slew +0.001211s ntpd: time slew +0.001200s ntpd: time slew +0.001855s ntpd: time slew +0.001532s ntpd: time slew +0.001603s ntpd: time slew +0.001320s ntpd: time slew +0.001931s badclock# ksh ./xenclockdrift ntpd: time slew -0.000193s ntpd: time set -57.356377s ntpd: time slew +0.002352s ntpd: time slew +0.003018s ntpd: time set -57.417488s ntpd: time slew +0.012089s ntpd: time slew -0.000985s These domains are fully virtualized and set up identically, except "badclock" is allocated two processors versus one processor for "goodclock". DomU's clock is running normally. Anyone know what's going or know how to fix it? Jack

After 4.6 update: CUPS (via Samba): "'/printers/printers' no good!"
by Steve Snyder 09 Jan '08

09 Jan '08

Since updating from 4.5 to 4.6 yesterday, I am getting a lot of CUPS errors. The error.log file is filling up with these messages: get_printer_attrs: resource name '/printers/printers' no good! And the access.log seems to be being polled often too, even in the absence of any print jobs submitted. On my network the CUPS-handled printer is exported from Samba. Given that the Samba RPMs were among those upgraded, I have to wonder what printing-related changes might have occurred. The hal-cups-utils was also updated in the course of the upgrade. I also notice that CUP's ppds.dat and cupsd.conf files have modification timestamp from around the time I did the upgrade. Any advice as to how to fix whatever was broken in the course of doing the upgrade? Thanks.

Switching To Raid1
by Matt 09 Jan '08

09 Jan '08

I have this ASUS M2NBP-VM motherboard http://tinyurl.com/3xby3h running CentOS 4.4 as a web/email server. It has a 500Gb SATA2 drive with about 32Gb in use. The motherboard supports hardware raid. Is there a way to switch to RAID1 without reinstalling or loosing any data? Also, if I am running raid how do I know if there is a failure on one of the drives anyway? Is hardware RAID1 a good idea? Matt

CentOS and GCC Question
by Clint Dilks 09 Jan '08

09 Jan '08

Hi People I am trying to build a piece of software from source in this case aide 0.13.1 using this config line ./configure --with-zlib --with-selinux. The configure step completes but there is a Warning that concerns me. This is taken from config.log configure:9809: checking for mhash_get_block_size in -lmhash configure:9844: gcc -o conftest -g -O2 -static -static conftest.c -lmhash -lz >&5 /usr/bin/ld: cannot find -lmhash collect2: ld returned 1 exit status The machine I am trying to do this build on is Cent0S 5 with the latest updates. It didn't originally have gcc installed so I have installed that and mhash and mhash-devel are also installed. I know I can ignore the warning and just carry on, or that there are already aide RPMS. But I am doing this as an exercise for myself as I want to up skill in RPM creation. So if anyone can offer incite into why this is happening it would be appreciated. rpm -qa | grep gcc libgcc-4.1.2-14.el5 gcc-4.1.2-14.el5 rpm -qa | grep mhash mhash-0.9.9-1.el5.centos mhash-devel-0.9.9-1.el5.centos Please let me know any other information that would be useful, have a nice day :)

max mount count incovenient
by Linux Man 09 Jan '08

09 Jan '08

Hello group I added a new partition in fstab, and works without a problem. I used mkfs.ext3 to create the partition. My problem is that every 26 boots, the system tells that the partition have no been checked since 26 systems boots, ant start to check my new partition. This is a lot of time consuming, and always is in a bad time. There some way to do the check in a controlled time? i.e. do it the check before 26 system boot, when the time is no problem. Thanks a lot Best regards
