Cpus_allowed_list issue in RHEL6.4
by Miraj Mohamed 24 Jul '13

24 Jul '13

Hi All, I am using RHEL 6.4 on a Dell Server with 32 cores. But in the Cpus_allowed_list only 30 cores are available. Why is that? See the snippet from cat /proc/self/status: Cpus_allowed: 7fff7fff Cpus_allowed_list: 0-14,16-30 The allowed list is same for the init process as well (see below). I didn't see this issue, in RHEL 6.2. Why is that? Is there a way to change it? -miraj ------------------------------------- [root@localhost bin]# uname -a Linux localhost 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux [root@localhost bin]# [root@localhost bin]# [root@localhost bin]# cat /proc/1/status Name: init State: S (sleeping) Tgid: 1 Pid: 1 PPid: 0 TracerPid: 0 Uid: 0 0 0 0 Gid: 0 0 0 0 Utrace: 0 FDSize: 64 Groups: VmPeak: 19364 kB VmSize: 19356 kB VmLck: 0 kB VmHWM: 1544 kB VmRSS: 1544 kB VmData: 328 kB VmStk: 88 kB VmExe: 140 kB VmLib: 2348 kB VmPTE: 52 kB VmSwap: 0 kB Threads: 1 SigQ: 1/256326 SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000000000 SigIgn: 0000000000001000 SigCgt: 00000001a0016623 CapInh: 0000000000000000 CapPrm: ffffffffffffffff CapEff: fffffffffffffeff CapBnd: ffffffffffffffff Cpus_allowed: 7fff7fff Cpus_allowed_list: 0-14,16-30 Mems_allowed: 00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000003 Mems_allowed_list: 0-1 voluntary_ctxt_switches: 1603 nonvoluntary_ctxt_switches: 62

rpmbuild environment CentOS5 vs CentOS6
by Peter Wood 24 Jul '13

24 Jul '13

On CentOS5 I was used to create a simple spec file where at the end I'll declare files and directories I wan't to package: --< Snip >-- %files %dir /opt/myapp %dir /opt/myapp/bin %dir /opt/myapp/etc /opt/myapp/bin/exec01 /opt/myapp/etc/myapp.conf ---- I'll copy the file in /usr/src/redhat/SPECS and run "rpmbuild -bb myapp.spec". On CentOS6 rpm-build package no longer creates the /usr/src/redhat/... directory tree. I followed the CentOS6 Wiki instructions to setup my rpmbuild environment for a regular user. When I try to build the package on CentOS6 I'm getting this error for every single file and directory: File not found: /home/peter/rpmbuild/BUILDROOT/myapp-5.2-1el6.x86_64/opt/myapp/bin/exec01 I tried to override buildroot: rpmbuild -bb --define="buildroot /" myapp.spec error: %{buildroot} can not be "/" As a workaround I can manually create /home/peter/rpmbuild/BUILDROOT/myapp-5.2-1el6.x86_64/ and copy all my file in there but that's a lot of extra work. Is there a way to get the same functionality on CentOS6 where rpmbuild will collect the files from the main / directory and build the rpm package? Thank you, -- Peter

NFS not exporting filesystem ACLs
by Gregory Machin 24 Jul '13

24 Jul '13

Hi. I have a test system in an lab I have copied over the /etc/sysconfig/nfs and /etc/exports from productions all the same services are running. But in the test environment the client mounts the nfs exports but the file system ACLs are not visible , what have I missed ? I have stopped the firewall on the server and that didn't help. Filesystem acls are enabled in fstab for the file system with the exports on it. We are using nfs v3 and it's configured on the server and in the mounts on the client. Thanks Greg

by Martin Šťastný 24 Jul '13

24 Jul '13

Hello, I am going to buy new laptop with two drives, one SSD and one HDD and I want to place swap partition on HDD which will be most time unused and therefore spinned down. Problem is, that I don't know, if or how often is kernel touching swap space even if there is lot of free memory and thus spinning HDD up. Thank you in advance

SELinux Question
by Ken Smith 23 Jul '13

23 Jul '13

Hi Guys, My google foo is failing me this afternoon. Just configuring a new C6 install. I know there are SELinux alerts happening, eg: I know I need to enable named to write to the local .jnl file as part of dynamic DNS, but sealert -b is not listing any alerts. I can see raw audit messages. Is there some daemon I have forgotten to start or install? Thanks Ken -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
