Command line partition manipulation
by Plant, Dean 08 Aug '08

08 Aug '08

I want to write a script to automatically modify the partition table I am starting with 3 partitions like this # parted /dev/sda print Model: VMware, VMware Virtual S (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot 2 107MB 4828MB 4721MB primary ext3 3 4828MB 9023MB 4195MB primary lvm And I want to remove partitions 2 & 3 and recreate 2 from the end of 1 to the end of the disk i.e. all the free space. Removing 2 and 3 is easy. # parted /dev/sda rm 3 # parted /dev/sda rm 2 # parted /dev/sda print Model: VMware, VMware Virtual S (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot Is there a way to use a non-interactive command to create the new 2nd partition in the free space? Thanks Dean

sound
by tony.chamberlain＠lemko.com 08 Aug '08

08 Aug '08

I am using Cent OS 4.6 and a USB speaker (no sound card but USB speaker works fine). Problem is, if I use something like xine or realplay and then later want to visit youtube through firefox, the youtube sound won't work, because even though I exited xine or realplay somehow it still has control of the sound device. Someone in fedora list suggested pulse audio but I can't get that installed. Any suggestions? I don't want to have to reboot my machine all the time.

pam max locked memory issue after updating to 5.2 and rebooting
by Rob Lines 08 Aug '08

08 Aug '08

We were previously running 5.1 x86_64 and recently updated to 5.2 using yum. Under 5.1 we were having problems when running jobs using torque and the solution had been to add the following items to the files noted "* soft memlock unlimited" in /etc/security/limits.conf "session required pam_limits.so" in /etc/pam.d/{rsh,sshd} This changed the max locked memory setting in ulimit as follows: Before the change rsh nodeX ulimit -a still gives us max locked memory (kbytes, -l) 32 After the change rsh nodeX ulimit -a max locked memory (kbytes, -l) 16505400 The nodes have 16gb of memory. Now after the 5.2 updates those files are all the same and on most of the nodes we haven't yet rebooted them due to log running processes but a few nodes have been restarted and now that jobs are starting to be put on them we are back to max locked memory of 32k rather than 16gb. The error we are receiving on those jobs is : libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes. This will severely limit memory registrations. libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes. This will severely limit memory registrations.

I looked through the list of packages that were updated and the only one that I could see that was related was pam. ssh and rsh were not updated. Thank you, Rob

CentOS 5.2 - Nautilus - file types are not associated with an action and icons are not displayed
by Vaclav Mocek 07 Aug '08

07 Aug '08

Hi all, I use CentOS 5.2 as a desktop and the Gnome Nautilus doesn't display icons related to the file types and all associated actions ("open with") are lost. It is so bad, that the desktop shortcuts are displayed as ordinary files "Filesystem.desktop" or "openoffice.org-1.9-calc.desktop", and when I click on them, the Nautilus wants to know what it should do with these files. The problem emerged after I installed the new kernel (2.6.18-92.1.10.el5) and uninstalled packages "joystick", "slrn" and "planner". All user accounts have the same problem, when I run the Nautilus as root (sudo nautilus), it works fine => probably some access restrictions. I run the Nautilus with strace, but the output is too messy to provide some sensible information. Any hint what to do is welcomed. Best Regards Vaclav

Hello All. How do I find out what flags were used to compile the Centos openldap-2.3.27-8.el5_2.4 rpm package? I'm specifically wondering if it was compiled with --enable-lmpasswd Thanks! -- Flambeau Inc.

Kernel 92.1.10 build issue
by Mark Hull-Richter 07 Aug '08

07 Aug '08

I pulled down the 2.6.18-92.1.10 source, installed it, built the package, copied the straight x86_64 config file from SOURCES into the build directory, redid make menuconfig to enable NTFS support, added the # x86_64 back into the .config file, copied .config back to the SOURCES directory and ran rpmbuild -ba --target=x86_64 <spec file> (same as I always do with new kernels), but this time I'm getting this error in the build: Patch #99990 (linux-2.6-rhel-version-h.patch): + patch -p1 -s + perl -p -i -e 's/^SUBLEVEL.*/SUBLEVEL = 18/' Makefile + perl -p -i -e 's/^EXTRAVERSION.*/EXTRAVERSION = -prep/' Makefile + perl -p -i -e 's/^RHEL_MAJOR.*/RHEL_MAJOR = 5/' Makefile + perl -p -i -e 's/^RHEL_MINOR.*/RHEL_MINOR = 2/' Makefile + cp /home/rpmbuild/SOURCES/COPYING.modules Documentation/ + mkdir configs + for cfg in 'kernel-2.6.18-x86_64*.config' + cp -f /home/rpmbuild/SOURCES/kernel-2.6.18-x86_64-debug.config /home/rpmbuild/SOURCES/kernel-2.6.18-x86_64-xen.config /home/rpmbuild/SOURCES/kernel-2.6.18-x86_64.config . + for i in 'kernel-2.6.18-x86_64*.config' + mv kernel-2.6.18-x86_64-debug.config kernel-2.6.18-x86_64-debug.config.tmp + /home/rpmbuild/SOURCES/merge.pl /home/rpmbuild/SOURCES/config-rhel-generic kernel-2.6.18-x86_64-debug.config.tmp + rm kernel-2.6.18-x86_64-debug.config.tmp + for i in 'kernel-2.6.18-x86_64*.config' + mv kernel-2.6.18-x86_64-xen.config kernel-2.6.18-x86_64-xen.config.tmp + /home/rpmbuild/SOURCES/merge.pl /home/rpmbuild/SOURCES/config-rhel-generic kernel-2.6.18-x86_64-xen.config.tmp + rm kernel-2.6.18-x86_64-xen.config.tmp + for i in 'kernel-2.6.18-x86_64*.config' + mv kernel-2.6.18-x86_64.config kernel-2.6.18-x86_64.config.tmp + /home/rpmbuild/SOURCES/merge.pl /home/rpmbuild/SOURCES/config-rhel-generic kernel-2.6.18-x86_64.config.tmp + rm kernel-2.6.18-x86_64.config.tmp + rm -f kernel-2.6.18-i686-kdump.config kernel-2.6.18-x86_64-kdump.config + rm -f kernel-2.6.18-i586.config + rm -f kernel-2.6.18-x86_64-debug.config + for i in '*.config' + mv kernel-2.6.18-x86_64-xen.config .config ++ head -1 .config ++ cut -b 3- + Arch=x86_64 + make ARCH=x86_64 nonint_oldconfig + echo '# x86_64' + cat .config + for i in '*.config' + mv kernel-2.6.18-x86_64.config .config ++ head -1 .config ++ cut -b 3- + Arch=x86_64 + make ARCH=x86_64 nonint_oldconfig CONFIG_MAX_RAW_DEVS make[1]: *** [nonint_oldconfig] Error 1 make: *** [nonint_oldconfig] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.53835 (%prep) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.53835 (%prep) Was there something I needed to tweak in the spec file, other than the build id and a few of the build switches I usually turn off (xen, debug, kdump)?
