Manual OOM killing?
by Alan McKay 25 Jul '12

25 Jul '12

Hey guys and gals, Yesterday I had one of my scientists kill one of my servers when his program ran amok and gobbled up all the memory, or forked too many processes, or I'm just not exactly sure what to be honest. Is there something I can run manually in cron to look for rampant programs and kill them? I know that may be hard to discern but I could also include a list if "known good" programs not to kill, as well as a list of "known suspect" user IDs Anyone ever done this? Searching the list on "OOM" does not bring up much. thanks -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

Bind isn't working. after upgrade.
by Carlos Sura 25 Jul '12

25 Jul '12

Hello Mates, I just reciently updated BIND on my CentOS 6.2 (don't remember which version) but now I am using version: BIND version 9.8.2 The packages I have: bind bind-libs bind-chroot bind-utils bind-devel First of all, doing "service named status" it throws me: WARNING: key file (/etc/rndc.key) exists, but using default configuration file (/etc/rndc.conf) rndc: connection to remote host closed This may indicate that * the remote server is using an older version of the command protocol, * this host is not authorized to connect, * the clocks are not synchronized, or * the key is invalid. After a Google search I found: to remove rdnc.key and it was suppose to be working ok. and I chown named:named the file /etc/named.conf, now if I do "service named status" it throws me: version: 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6_3.1 CPUs found: 4 worker threads: 4 number of zones: 17 debug level: 0 xfers running: 0 xfers deferred: 0 soa queries in progress: 0 query logging is OFF recursive clients: 0/0/1000 tcp clients: 0/100 server is up and running named (pid 1456) is running...

RAID card selection - JBOD mode / Linux RAID
by Alan McKay 25 Jul '12

25 Jul '12

I don't think this is off topic since I want to use JBOD mode so that Linux can do the RAID. I'm going to hopefully run this in CentOS 5 and Ubuntu 12.04 on a Sunfire x2250 Hard to get answers I can trust out of vendors :-) I have a Sun RAID card which I am pretty sure is LSI OEM. It is a 3G/s SAS1 with 2 external connectors like the one on the right here : http://www.cablesondemand.com/images/products/CS-SAS1MUKBCM.jpg And I have 2 x Sun J4400 JBOD cabinets each with 24 disks. If I buy a new card that is 6G/s SAS2 with the same connector, can I connect my cabinets to it and have them work? Even if they only work at 3G/s I don't care. I've also hit an issue with the number of logical devices allowed, and am wondering whether this might be a HW, FW or SW limitation if anyone knows. I want to run everything in JBOD mode and let Linux do the RAID. So for the first cabinet I ran this command 24 times to create a logical drive for each physical one /usr/StorMan/arcconf create 1 logicaldrive max volume 0,X noprompt Where X goes from 0 to 23 Went great, created /dev/sd[c-z] and I was able to use those with mdadm to create 4 x RAID6 arrays and then a big RAID0 out of the 4 x RAID6. Works great! Then I try to connect the 2nd cabinet and when I run the above arcconf command it tells me there are already 24 logical devices, and this is the max. Anyone know whether that is HW, FW or SW? Would a new card fix this problem? Anyone know for sure of a card with above connectors that has a JBOD mode that will support 48 drives and expose them all to Linux? -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

Sorry if I pasted in > stuff to confuse. Whoa, Mark. Man, you must be tired. The fact that your machine with the 290 driver only sees the kmod-nvidia for 295 and does not see nvidia-x11-drv is a big clue. You might want to double check the includepkgs= line on the machine you originally posted about (not this latest machine), and make sure that it isn't: includepkgs=nvidia-x11-drv I can duplicate this behavior very easily, and can duplicate the reverse behavior as well, by manipulating the includepkgs= line. Here's an example run, from a RHEL 6.3 machine (same would apply to CentOS, just with a few differences in the yum output dealing with the RHN repos....): <MVNCH> Works fine. The includpkgs= line has to include all dependencies, as it really does do what the man page says it does. Try it without the includepkgs= line, or with it commented out, and see if you get different results. Thank you *so* much - this works. One oddity: originally, I'd had only includepkgs=kmod-nvidia, *not* the nvidia-x11-drv. My last try, last week, I'd added extra lines with that on two separate lines: includepkgs=kmod-nvidia includepkgs=nvidia-x11-drv Just now, following your example, I put them on one line includepkgs=nvidia-x11-drv kmod-nvidia and it worked with no problem at all. Odd. And for the guy from the elrepo team, you'll note it was *not* an elrepo problem, which is what I'd suspected, unless the repodata file's changed since Friday. mark

This option is kept for legacy purpose [1] (or man yum). It works yet but will be removed in the future releases (years ago) I believe.
