Routing issue
by Steve Clark 03 Oct '12

03 Oct '12

Hello, This is on Centos 6 and not something I think is wrong with Centos 6 but I am looking to see if anybody else has experienced this and if there is solution. So thanks up front for indulging me. Because Linux makes routing decisions before SNAT it is causing problems when trying to use FTP with two upstream providers in a load balanced setup. Other than ftp, things seem to work OK. Below is my setup and tcpdump output that shows ftp packets trying to go out the wrong interface. ip ru sh 0: from all lookup local 200: from y.y.y.174 lookup t1 201: from x.x.x.217 lookup t2 32766: from all lookup main 32767: from all lookup default ip r s y.y.y.129 dev eth1 scope link 172.16.0.0/29 dev gre1 proto kernel scope link src 172.16.0.1 y.y.y.128/25 dev eth1 proto kernel scope link src

Logrotate "firstaction" with non-0 exit status. Or: How to keep logrotate from rotating via scripts?
by Toralf Lund 03 Oct '12

03 Oct '12

Hi, I'm wondering if anyone here has any experience with the "firstaction" script in logrotate config files, or more specifically, the behaviour with a non-0 exit status. The logrotate manpage says: firstaction/endscript The lines between firstaction and endscript (both of which must appear on lines by themselves) are executed (using /bin/sh) once before all log files that match the wildcarded pattern are rotated, before prerotate script is run and only if at least one log will actually be rotated. These directives may only appear inside a log file definition. Whole pattern is passed to the script as first argument. If the script exits with error, no further processing is done. See also lastaction. My question is, what exactly does "no further processing is done" mean? The obvious interpretation seems to be that the log file will not be rotated, but based on tests I've done, this does not seem to be the case. If I run logrotate with this config: /tmp/testfile { missingok size 0 rotate 1000 copytruncate firstaction false endscript } I get the message: error: error running first action script for /tmp/testfile But /tmp/testfile is still copied to /tmp/testfile.1 (provided that it exists.) Then if I run again, I end up with /tmp/testfile, /tmp/testfile.1 and /tmp/testfile.2, and so on... Does this mean the manpage note must be interpreted differently? Or is perhaps the behaviour buggy? And, is there any way at all I can use commands in the config file to control whether the rotation is done or not; this is what I'm looking for, really? I've tested this on CentOS release 5.8... - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.

Weird behaviour of ifcfg scripts
by Timo Schoeler 02 Oct '12

02 Oct '12

Hi, I accidentally found that the existence of a file e.g. named ifcfg-eth1:1 put in /etc/sysconfig/network-scripts/ leads to the appropriate interface being created even with the option 'ONBOOT' set to 'no': DEVICE="eth1:1" BOOTPROTO="static" NM_CONTROLLED="no" ONBOOT="no" TYPE="Ethernet" IPADDR=12.34.56.78 NETMASK=255.255.255.0 Is that intended behaviour?

s3 as mysql directory
by Tim Dunphy 01 Oct '12

01 Oct '12

Hello list, I am soliciting opinion here as opposed technical help with an idea I have. I've setup a bacula backup system on an AWS volume. Bacula stores a LOT of information in it's mysql database (in my setup, you can also use postgres or sqlite if you chose). Since I've started doing this I notice that the mysql data directory has swelled to over 700GB! That's quite a lot and its' easting up valuable disk space. So I had an idea. What about uses the fuse based s3fs to mount an S3 bucket on the local filesystem and use that as your mysql data dir? In other words mount your s3 bucket on /var/lib/mysql I used this article to setup the s3fs file system http://benjisimon.blogspot.com/2011/01/setting-up-s3-backup-solution-on-cen… And everything went as planned. So my question to you dear listers is if I do start using a locally mounted s3 bucket as my mysqld data dir, will performance of the database be acceptable? If so, why? If not are there any other reasons why it would NOT be a good idea to do this? The steps I have in mind are basically this: 1) mysqldump --all-databases > alldb.sql 2) stop mysql 3) rm -rf /var/lib/mysql/* 4) mount the s3 bucket on /var/lib/mysql 5) start mysql 6) restore the alldb.sql dump Thanks for your opinions on this!

Deduplication data for CentOS?
by Rainer Traut 01 Oct '12

01 Oct '12

Hi list, is there any working solution for deduplication of data for centos? We are trying to find a solution for our backup server which runs a bash script invoking xdelta(3). But having this functionality in fs is much more friendly... We have looked into lessfs, sdfs and ddar. Are these filesystems ready to use (on centos)? ddar is sthg different, I know. Thx Rainer

High memory needs
by Jérémie Dubois-Lacoste 01 Oct '12

01 Oct '12

Dear All, We recently reinstalled our computing cluster. We were using CentOS 5.3 (32 bits). It is now CentOS 6.3 (64 bits), installed from the CentOS 6.2 x64 CD, then upgraded to 6.3. We have some issues with the memory needs of our running jobs. They require much more than before, it may be due to the switch from 32 to 64 bits, but to me this cannot explain the whole difference. Here are our investigations. We used the following simple benchmark: 1. Run a python script and check the memory that it requires (field "VIRT" of the "top" command). This script is: ---- import time time.sleep(30) print("done") ---- 2. Similarly, run and check the memory of a simple bash script: ---- #!/bin/bash sleep 30 echo "done" ---- 3. Open a R session and check the memory used I asked 10 of our users to run these three things on their personal PCs. They are running different distributions (mainly ubuntu, slackware), half of them use a 32 bits system, the other half a 64 one. Here is a summary of the results: Bash script: Avg Min Max 32 bits 5400 4192 9024 64 bits 12900 10000 16528 Python script: Avg Min Max 32 bits 8500 5004 11132 64 bits 32800 30000 36336 R: Avg Min Max 32 bits 26900 21000 33452 64 bits 100200 93008 97496 (as a side remark, the difference between 32 and 64 is surprisingly big to me...). Then we ran the same things on our CentOS cluster, getting surprisingly high results. I installed a machine from scratch with the CentOS CD (6.2 x64) to be sure another component of the cluster was not playing a role. On this freshly installed machine I get the following results: SH: 103MB PYTHON: 114MB R: 200MB So, compared to the highest of our users (among the 64 bits ones), we have a ratio of ~7, ~3, ~2, respectively. It is very problematic for us because many jobs now cannot run properly, because they lack memory on most of our computing nodes. So we really cannot stand the situation... Do you see any reason for this? Do you have suggestions? Sincerely, Jérémie

Doubled up RAM to 32 GB - now how to speed up a LAPP server?
by Alexander Farber 01 Oct '12

01 Oct '12

Dear CentOS users, I run a small Facebook game at a CentOS 6.3 machine with PostgreSQL 8.4.3 + few PHP scripts + 1 Perl daemon and even though the server worked ok, I've suggested my users to double up the RAM to 32 GB and they have collected money for that. Now my problem is that I don't know, which knob to turn and how to really use the additional memory. Below is my top output at the peak time (evenings) - as you see, 27 GB of RAM aren't used: # top - 18:47:55 up 23:12, 2 users, load average: 2.17, 2.31, 2.56 Tasks: 246 total, 2 running, 244 sleeping, 0 stopped, 0 zombie Cpu(s): 12.1%us, 0.2%sy, 0.0%ni, 87.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 32790380k total, 5296664k used, 27493716k free, 197132k buffers Swap: 2096056k total, 0k used, 2096056k free, 3815840k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12363 postgres 20 0 4376m 717m 710m S 40.6 2.2 2:03.48 postmaster 3842 nobody 20 0 118m 23m 3920 S 12.0 0.1 46:24.68 pref.pl 9178 postgres 20 0 4375m 518m 514m S 11.3 1.6 53:50.63 postmaster 12380 postgres 20 0 4377m 668m 660m S 11.3 2.1 2:33.26 postmaster 12243 postgres 20 0 4377m 668m 662m S 9.3 2.1 2:20.49 postmaster 12438 postgres 20 0 4374m 502m 498m S 6.3 1.6 1:03.34 postmaster 12249 postgres 20 0 4384m 852m 839m S 3.0 2.7 3:59.11 postmaster 12241 postgres 20 0 4378m 632m 625m S 1.7 2.0 2:48.62 postmaster 12156 apache 20 0 366m 27m 17m S 1.0 0.1 0:05.12 httpd 36 root 20 0 0 0 0 S 0.3 0.0 0:01.32 events/1 100 root 39 19 0 0 0 S 0.3 0.0 0:06.04 khugepaged 9217 postgres 20 0 21976 1036 516 S 0.3 0.0 1:01.07 pgbouncer 12010 apache 20 0 376m 37m 17m S 0.3 0.1 0:07.58 httpd 12280 apache 20 0 370m 30m 16m S 0.3 0.1 0:03.17 httpd 12362 apache 20 0 365m 15m 6816 R 0.3 0.0 0:01.90 httpd 12457 apache 20 0 360m 9.8m 3456 S 0.3 0.0 0:00.14 httpd 1 root 20 0 19352 1584 1284 S 0.0 0.0 0:01.03 init 2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd # vmstat 10 procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 6 2 0 27323416 196988 3852536 0 0 3 165 15 9 14 0 84 2 0 1 0 0 27422148 197012 3814860 0 0 0 5284 4784 2104 46 1 51 2 0 1 0 0 27454748 197020 3826656 0 0 4 1734 2021 1200 16 0 83 1 0 0 2 0 27514008 197028 3813464 0 0 0 702 1475 1208 8 0 90 2 0 0 0 0 27465612 197040 3813968 0 0 0 1435 1764 1725 10 0 85 5 0 1 0 0 27459260 197060 3814248 0 0 0 2032 2667 1304 22 0 76 1 0 1 0 0 27440076 197064 3827064 0 0 0 1604 3146 2109 27 0 72 1 0 1 0 0 27466796 197068 3814868 0 0 2 1241 2014 1637 13 0 83 3 0 4 0 0 27380104 197072 3848256 0 0 0 1064 2375 894 20 0 79 1 0 1 0 0 27488168 197096 3815296 0 0 0 2075 2697 2220 23 0 75 1 0 1 0 0 27462168 197116 3821380 0 0 0 871 1750 943 13 0 86 1 0 4 0 0 27432100 197128 3822320 0 0 0 3980 4767 2340 46 1 53 1 0 0 0 0 27493716 197132 3815844 0 0 0 1871 3209 2078 27 0 72 1 0 3 0 0 27424284 197132 3827036 0 0 0 1452 2551 1487 18 0 78 3 0 3 0 0 27435428 197160 3824116 0 0 0 2066 3430 2082 29 0 70 1 0 2 0 0 27452004 197172 3817440 0 0 0 1356 2722 1895 23 0 76 1 0 2 0 0 27436668 197176 3826648 0 0 0 1633 3629 2162 30 0 69 1 0 1 0 0 27439924 197204 3823124 0 0 0 1502 1786 1293 14 0 86 0 0 0 0 0 27466696 197212 3816780 0 0 0 1200 1701 1164 13 0 86 0 0 3 0 0 27432204 197212 3818344 0 0 0 2587 2098 2154 16 0 83 1 0 2 0 0 27421088 197224 3827224 0 0 0 1229 2635 1421 21 0 75 3 0 3 0 0 27319136 197232 3832088 0 0 13 2965 4220 1951 40 0 59 1 0 procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu----- What I've already done: /var/lib/pgsql/data/postgresql.conf (local connections only) max_connections = 10 shared_buffers = 4096MB work_mem = 16M /etc/php.ini memory_limit = 300M [PostgresSQL] pgsql.allow_persistent = Off # because I use pgbouncer /etc/pgbouncer.ini (local connections only too) max_client_conn = 600 default_pool_size = 80 /etc/httpd/conf/httpd.conf (didn't modify yet): <IfModule prefork.c> StartServers 10 MinSpareServers 8 MaxSpareServers 30 ServerLimit 512 MaxClients 512 MaxRequestsPerChild 4000 </IfModule> Any suggestions please?
