[CentOS] RAID card selection - JBOD mode / Linux RAID
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 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] pvcreate limitations on big disks?
OK folks, I'm back at it again. Instead of taking my J4400 ( 24 x 1T
disks) and making a big RAID60 out of it which Linux cannot make a
filesystem on, I'm created 4 x RAID6 which each are 3.64T
I then do :
sfdisk /dev/sd{b,c,d,e} EOF
,,8e
EOF
to make a big LVM partition on each one.
But then when I do :
pvcreate /dev/sd{b,c,d,e}1
and then
pvdisplay
It shows each one as only half its actual size.
But if I take the last one and wipe the partition table and just do
pvcreate on the entire disk, it works
pvcreate /dev/sde
And then if I take the results from that and use the size to force a
size on another PV I get it right too
pvcreate /dev/sdd1 --setphysicalvolumesize=3.64T
I'd use the entire disk expect that this seems dangerous to me because
you do sfdisk -l and the disk appears to have no partition table
which might entice someone to thing it is unused.
And I'm not sure whether it is safe to use setphysicalvolumesize.
Anyone know for sure?

[CentOS] process accounting on 5.7
Hey folks, I turned on process accounting and had a peek at the man page for dump-acct but I am still left wondering how best to make use of this info. We want to be able to produce some monthly stats on which labs are using how much of our clusters.I know our clustering software has the ability to do this but unfortuantely not everyone uses the cluster commands as much as I keep reminding them. Would be nice to be able to show that user X used Y% of the CPU in a given month.

[CentOS] debugging RAM issues
Hey folks, I have 1 system ( Sunfire x2250 running 5.7 ) that is having issues with RAM, but I'm not sure how to debug it. And unfortunately it is not under support anymore. I started the job about 4 months ago and when I came aboard the guy who handed stuff over to me told me this issue was on his list of things he was unable to get to yet. He told me he'd seen errors in the past in the Sun ILOM message log, but unfortuantely he did not record exactly what the messages were. Fast forward a bit and I've had problems with this machine. Sometimes when I reboot it, it just won't come up. The console and everything just go completely dead no matter what I do. I unplug it for a while and try again, same thing. It seems to just randomly come back to life, and when it does I see something in the ILOM log like this : ID = f74 : 03/07/2012 : 19:17:42 : System Firmware Error : ACPI : No usable system memory So it seems to me that when it is having trouble, it is not seeing any RAM at all. And when it does come back up, Linux only sees half the RAM it is supposed to see. lshw sees all the RAM The only errors I see in the ILOM logs are above. I don't see anything in dmesg or /var/log/messages on the Linux side. Back about 3 months ago I took this system down and removed all the RAM, and stuck individual chips into it and booted it, testing each chip on its own. At that time every single one of them worked! But I'm about to try this again to see what happens. Back then I also ran memtest86 for some time and it seemed OK too. Other than that I'm a bit stumped on how to get to the bottom of this. Tips? I googled the error and got precisely 1 hit at a university high performance computing center in Utah, so I dug up a contact there and emailed them hoping they could tell me something, but I have not yet heard back. thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] schily tools

Which leads me to believe that the Schily tools are maybe a bit rogue My basic requirement with what I'm doing is to use standard tools and formats so that archives I write today can be readable in 10 years.

Re: [CentOS] schily tools
Are you reading something that favors Solaris/*bsd over GNU based systems? No, why, are the Schily tools standard over there? I've never had any doubts that current GNU tar would extract archives made with it 10+ years ago - in fact I'm fairly sure I've done that. Or that I'd be able to obtain a copy of it in the future. Yeah, that is the plus side. But it seems gtar is rather abysmal at recovering from errors in archives so if there is ever a problem, you're cooked.

Re: [CentOS] schily tools
I don't think so - I'm fairly sure I've seen GNUtar complain about bad headers, say 'skipping to next header' and then find something.

As an aside to my current line of questioning, I was looking for an excuse not to compress and you just gave it to me! Yay!

Is there any way to get gtar to report on the compression it achieved? I can't just check file sizes because I'm writing data to tape.

Re: [CentOS] gtar compression achieved
Is there some reason you aren't using amanda? Give it some holding
disk space and it will run multiple backups at once, buffering on
disk, and figure out how they should go on the tape for you.
I'm archiving, not backing up.
I looked at Amanda for a few days and it would be really clunky to do what
I want.
Anyway I found this :

Re: [CentOS] gtar compression achieved
I haven't used it for a while, but I thought it had an indexing mechanism that would let you tell it what you want and it would tell you the tapes you need and the order to restore them (for full + incremental cases). And it could re-index the tapes if you lost the disk copy. Maybe that doesn't fit your use, but it seemed handy. In general it is massive overkill for what Im doing. Even if I wanted to switch backup solutions and move my backups to Amanda it would not be worthwhile to get this as an add-on because of the nature of the data I am dealing with. Case in point I have about 300G of data that one of the scientists copied over to my server from a piece of scientific equipment. That 300G was never in my backups and I never want it to be. But he needs it archived. Amanda is just way, way too too big for this. In 2 weeks I've got a program written that is tailored exactly to our needs. THat's probably less time than it would have taken me to deploy Amanda. And it would not have been tailored precisely to our needs. -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Is Amanda vaulting what I need for archiving data?
Hi folks, I've got a bit of a different scenario than I imagine most, and have spent the last 60 or 90 minutes searching Amanda list archives and googling, but did not come up with anything much. Then I went browsing around the Amanda website and found vaulting and was wondering whether this would suit my needs. I'm basically searching around for a backup solution and trying to decide whether to use something off the shelf or just roll my own with gtar. It is important to me that my solution use standard tools like dump/restore / gtar on the back end, which is how I ended up at Amanda. In looking through some of the initial configuration how-tos it seemed as though this was massively over-complex for my application. But then I hit upon vaulting http://wiki.zmanda.com/index.php/How_To:Copy_Data_from_Volume_to_Volume This is not exactly my scenario, but maybe there is another way to roll a vaulting solution to suit me. Basically I work in a scientific research lab (stem cell research) where the scientists produce a fair bit of raw data. We want to periodically take the data and archive it to tape and then remove it from disk and store the tape in our archival facility. We'd need a record of what is on each tape of course. But this would not be the same scenario as in the link above because it would not be taking data from 2ndary to tertiary storage. It would essentially be taken from primary to tertiary directly. i.e. directly from disk to tape. But not in an automated fashion like typical nightly dumps. On request, we'd take the scientist's data and copy it over to our server that has the tape unit, then dump it out to tape, and remove it from the disk there. Once verified, we could tell the scientist it is OK to remove their primary data now, and then we'd store the tape. Is Amanda suited to this? Or is there another application I should be looking at? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Is Amanda vaulting what I need for archiving data?
For one thing, I think you seriously need to look at backup up to offline hard drives, instead of tapes. Unless you really want/need to archive the tapes for seven years Well, the scientists are talking longer than 7 years so HDs just are not going to cut it We back up to backup servers, then, every couple of weeks, I run rsync backups (well, we have a locally-rolled system to run the rsync) onto offline drives - in our case, I swap large drives into an eSATA drive bay.

Yes, the default setup really goes out of its way to defeat any standard caching proxies and make the mirrors do extra work, although once you accumulate the copies from 5 or 6 sources everything will work like you expect. That used to bother me but now the mirrors seem to be insanely fast so if your own connection is good it just doesn't matter. Part of my problem is that my own connection is absolutely terrible. Anyway, I'll figure something out. What I'll probably end up doing is taking my laptop home and rsycing a mirror to it, then taking it back into work and shooting that over to my server. Though just for giggles I'm going to try to get central IT to unblock rsync for me :-) -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] forcing yum to download but not install
That is one advantage of the way automirror worked, since it was specific to yum it didn't mind the mirror configuration. Yes, would be nice if it worked for me :-( One way around the mirror list issue is pointed out by Guru labs (though I admit hijacking the DNS seems heavy handed) http://www.gurulabs.com/goodies/guru-guides/YUM-automatic-local-mirror/ I'll look at it. I just installed the yum-downloadonly on one box and am starting the upgrade with that flag enabled. Then I suppose I can mount the cache directory on other servers before updating them and I should be golden Given that I've only got 5 or 6 boxes to do it should not be a major problem.

Re: [CentOS] Monitoring services
Do Zabbix or Zenoss allow for this sort of testing that Nagios has? yes. OK, thanks.

Re: [CentOS] Monitoring services
OK, I've had a Zabbix and a Zenoss server running now for 2 or 3 days and would like to morph this thread into a discussion of what each of these systems can and cannot do. At the base of what I see so far, Zabbix is only able to monitor devices that have the Zabbix agent on it - is that correct? On the one hand I like having an agent on the remove device since it allows you to have functionality that is more purpose-driven to what we are trying to do. On the other hand, what above devices that cannot run the agent? e.g. monitoring switches and routers. Though to counter my own concern - those are the sorts of things that are either up or down anyway and Im not sure that they can be monitored per-se outside of that. Sure you can graph their traffic and so forth, but is any monitoring software able to actually say there is a potential problem with your router or switch? Other than your device is now down which is pretty easy to figure out anyway without monitoring software since just about anything connected to it is going to start throwing alarms once it is down. Zenoss seems to let you monitor anything via SNMP which may not necessarily be as purpose-driven as having an agent, but it does allow you to monitor just about anything under the sun since pretty much everything supports SNMP. On the upside, getting this ste up has forced me to do some reading on configuring net-snmp on Linux and I've gotten that working and it could turn out to be useful elsewhere even if I do not choose Zenoss As for the dashboard and general web interface, configuring things, viewing things and so on, both of them seem to be pretty easy to set up and use. I find the Zabbix interface a little more useful, with better default graphs and so on. But I'm still left wondering whether I should fall back to Nagios. One very nice thing about Nagios is that you can do some really fine-grained tests on systems to determine whether or not it is currently working. Like you can log in to an FTP server and test for a specific file or something like that. You are always testing from the outside which may have its downsides too, but it has a lot of upsides because that's how users view the boxes anyway - from the outside. Do Zabbix or Zenoss allow for this sort of testing that Nagios has? Incidentally I also looked at OpenNMS which has a live demo online - I don't like the dashboard and basic functionality as much as Zabbix or Zenoss. And since I did not set it up myself nor configure it, I cannot comment on that. I am also looking at Icinga which is a fork of Nagios but seems to have gone in a very different direction after the fork. They have a live demo on their site as well. I have not dug much into this yet so cannot comment on how I like.

Re: [CentOS] Monitoring services
Thoughts form anyone on any of this? Network monitoring is not trivial no matter what tool you use. Pick something that you trust to scale to the proportions you will need so you don't do a lot of work and then hit a wall. And if you have a lot of systems, avoid anything that needs per-system configuration or agent installation. Agreed. I'm definitely not looking for trivial - just trying to make sure I understand the strengths and weaknesses of each system to help me make the right decision. Because once I've made that decision, I have to live with it :-) Our environment is relatively small. About 80 servers that are mostly grouped into 3 compute clusters for the scientists I support. A few switches, and no routers under my direct control (though a few Linux boxes routing between NICs since some of the environment is on our own private LAN behind said Linux box, cut off from the Hospital's network) cheers, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] auto-creating a local yum cache?
Hey folks, I just did an update on a system that is taking the better part of a day ( 5.3 --- 5.7 ) mainly due to file download times. And I have 4 or 5 more systems to do. I know I can create my own repository and then point them at it - but that is difficult here because rsync is blocked (ggrr...) Surely there must be a way to have yum on the first box automatically cache everything and then have the other boxes use the cache? Maybe if not directly, then with squid or something like that?

[CentOS] iSCSI best practices
Hey folks, I had some general questions and when reading through the list archives I came across an iSCSI discussion back in February where a couple of individuals were going back and forth about drafting up a best practices doc and putting it into a wiki. Did that ever happen?And if so, where is it? Now my questions : We are not using iSCIS yet at work but I see a few places where it would be useful e.g. a number of heavy-use NFS mounts (from my ZFS appliance) that I believe would be slightly more efficient if I converted them to iSCSI. I also want to introduce some virtual machines which I think would work out best if I created iSCSI drives for them back on my Oracle/Sun ZFS appliance. I mentioned iSCSI to the guy whose work I have taken over here so that he can concentrate on his real job, and when I mentioned that we should have a separate switch so that all iSCSI traffic is on it's own switch, he balked and said something like it is a switched network, it should not matter. But that does not sit right with me - the little bit I've read about iSCSI in the past always stresses that you should have it on its own network. So 2 questions : - how important is it to have it on its own network? - is it OK to use an unmanaged switch (as long as it is Gigabit), or are there some features of a managed switch that are desirable/required with iSCSI? thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Backup Redux
Hey folks, I just went through the archives to see what people are doing for backups, and here is what I found : - amanda - bacula - BackupPC - FreeNAS Here is my situation : we have pretty much all Sun hardware with a Sun StorageTek SL24 tape unit backing it all up. OSes are a combination of RHEL and CentOS. The software we are using is EMC NetWorker Management Console version 3.5.1.Build.269 based on NetWorker version 7.5.1.Build.269 The pickle we are in right now is that this software is Java based, and stops working at a very specific release of JRE (1.6.26 or something like that). We still have some machines around with that release and it looks like we need to keep at least 1 of them, but this is clearly not a long term viable solution. In the end I want to get our central IT group to take over our backups if possible (we are a bit of an island outside of central IT), but as I pursue that path I also want to pursue a 2ndary path assuming they will say no. I am familiar with BackupPC and will look at the other recommendations above. I think that Bacula and Amanda are sort of the drop-in replacements for what we have now so I'll look at them most closely. But if I do have to carry forward with our own backups I'd ideally like to get out of the tape game - never liked tapes. Anyway, since the last big backup discussion was over a year ago I figured I'd kick off another one to see if anything new has come up in the mean time.

[CentOS] ZFS magic (was: Backup Redux)
My non-tape solution of choice is definitely rsync = box with ZFS, snapshot however often you'd like. = forever incrementals. For more redundancy and performance, add more ZFS boxes, do replication between them. Not sure whether ZFS now makes this OT - if so, sorry for not putting OT: in the subject. Anyway, I have a ZFS storage unit here and this is my first exposure to it so I don't really know about any of this ZFS magic that I often hear about.
