imagemagick convert/display eps file no decode delegate
by Tony Schreiner 28 Apr '12

28 Apr '12

I am finding on all my CentOS 5.8 systems (all fully updated but a variety of package mixes) that the display or convert commands from ImageMagick are unable to handle eps files. I get error output as follows, curious if anyone else sees this $ convert rna.eps rna.epi convert rna.eps rna.epi Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 convert: no decode delegate for this image format `rna.eps'. convert: Postscript delegate failed `rna.eps'. convert: missing an image filename `rna.epi'. ImageMagick 5.2.8.0-12.el5 ghostcript-8.0-14.el5 the equivalent GraphicsMagick command gm convert does work This is a recent development, but I can't say how recent Tony Schreiner

Help with software raid + LVM on Centos 6
by aurfalien 27 Apr '12

27 Apr '12

Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it for swap) md2 All remaining space (use it for /) 2) Created two physical LVMs, one on md0, the other on md1. 3) ? This is were I am confused, do I create two LVM volume groups? I was thinking that my primary LVM can be ~1TB and that my other LVM which I snapshot to can also be ~1TB. Anyways, I am very green on this topic as I usually do hardware raids but I don't have that option. Thanks in advance, - aurf

Re: [CentOS] yum yum or not?

I have only this suspicion. It may be that yum history undo only rolls back the changes actually made by the previous yum update/install since it 'knows' that the system environment has not changed in the interim. Whereas yum history remove, since it has to cherry-pick packages from a possibly changed environment, instead removes rpm dependencies based on the package specs of the items directly added by the original yum command, whether these were installed in that transaction or not. But, this is only a guess. -- *** E-Mail is NOT a SECURE channel *** James B.

More on the ATA sense error
by m.roth＠5-cent.us 27 Apr '12

27 Apr '12

AFAIK, no one's responded to me about whether I should just turn off smartd. At any rate, here's more info: this server only started spitting Apr 25 07:47:50 <server> kernel: sda: Current [descriptor]: sense key: Recovered Err ror Apr 25 07:47:50 <server> kernel: Add. Sense: ATA pass through information availl able Apr 25 07:47:50 <server> kernel: Apr 25 07:47:50 <server> kernel: Descriptor sense data with sense descriptors (in hh ex): Apr 25 07:47:50 <server> kernel: 72 01 00 1d 00 00 00 0e 09 0c 00 00 00 00 00 00 Apr 25 07:47:50 <server> kernel: 00 4f 00 c2 40 50 for every drive - and it has four - right after updated to the most current kernel 2.6.18-308.4.1.el5 #1 SMP and rebooted. So one question becomes three: a) should I turn off smartd? b) should I reboot to the previous kernel, and see if it keeps up? c) is this a known bug? mark

fail2ban logrotate failure
by Bob Hoffman 27 Apr '12

27 Apr '12

I got the fail2ban from epel. There were a number of issues relating to using a log file... logwatch was looking for both fail2ban and fail2ban.log logrotate file fail2ban added looked for fail2ban.log and then reset itself to syslog fail2ban itself went to syslog, over riding its fail2ban.log. took a while, but I use /var/log/fail2ban now, that finally worked through logrotates and logwatch. Problem with centos variant of fail2ban: logrotate causes all 'ban' actions to stop happening. I am pretty sure it stops reading the logs but still functions. Unban actions still keep showing up in the log, but the 'ban' actions just stop. Program is running, but no longer working. Long searches online show a million others with the same issue. Only way to prevent it seems to be to add a reload or restart in the syslog file. This is undesired due to losing all banned ips listed. It happens as part of the logrotate. The logrotate file I have changed a few times and recently tried this postrotate /usr/bin/fail2ban-client set logtarget /var/log/fail2ban 1>/dev/null || true endscript setting the logtarget, which the original called for changing it to syslog and 2>dev/null || true so what would you do? I imagine when logrotate happens and syslog restarts something is causing fail2ban to stop working properly, but still timing 'unbans'. This is apparently a bug/problem for almost everyone of all distros. Other than just uninstalling, the only way to make it work would be a restart around 4 every morning, making any long term bans useless. My last thought is to just throw the /var/log/fail2ban to be rotated by syslog like maillog and the others..and not doing anything special. Maybe it would just work. I write here because I know there are hundreds of you and someone must have figured out how to make fail2ban work for more than 24 hours without a restart....

High load
by Kaushal Shriyan 27 Apr '12

27 Apr '12

Hi Is there a way to nail down the issue of high load on a server basically trying to understand the reason behind high load at a specific time period. I use top command but it does not have history. Nagios reports saying "*[04-25-2012 10:11:00] SERVICE ALERT: dev;LOAD;WARNING;HARD;3;WARNING - load average: 6.88, 6.36, 5.71"* * * Please help me understand. Regards Kaushal

High load averages copying USB
by Lists 27 Apr '12

27 Apr '12

Problem as follows: 1) Plug in an external USB drive. 2) Mount it anywhere. Doesn't matter how. 3) Copy a few GB of data to the drive from a non-USB disk. 4) Watch the load average "climb" to 5.x, sometimes 10.x or more. Why? This on an otherwise unloaded system. Doesn't matter how many cores, how much RAM, 32/64 bit, etc. Why should copying some files to a USB drive cause load averages to climb so high? (and network monitors to freak out?)
