similar to: reading vdump files?

I'm trying to rsync a 8TB data folder containing squillions of small files and it's taking forever (i.e. weeks) to get anywhere. I'm assuming the slow bit is check-summing everything with a single CPU (even though it's on a 12-core server ;-( ) Is it possible to do something simple like scp the whole dir in one go so they're duplicates in the first instance, then get rsync to

I've just setup nic bonding on our server (DL585-G7 running Centos 5.5 x86_64) as detailed on the wiki: http://wiki.centos.org/TipsAndTricks/BondingInterfaces and all seems fine but from other "howto's" I've seen on the web, they're should be a /proc/net/bond0/info As far as I can see, I don't have one and I'm not sure if it should be there or its absence is a

Hi all, I'm just poking thru our previous sysadmin's user adding script and saw reference to a ~/.forward file containing the users email address. Any idea what it might be for? It's a tricky one to Google ;-) Thanx, Russell Smithies ? ======================================================================= Attention: The information contained in this message and/or attachments from

I have a new server with multiple nics running Centos 6.2 and I'd like to force all NFS traffic over one nic. We're using FreeNAS to dish out NFS shares and I have different IPs on my 2 nics but how can I get the server to mount the share over one particular nic? Or is there a better way to do it? Thanx, Russell Smithies

I've got xen-3.0.3-105.el5_5.5 running on Centos 5.5 and all is running smooth but I notice that any VMs running under it only have access to Realtek RTL8139C at 100 Mbps nics. We have 4 x 1G nics configured in a port channel so I'd really like to be able to give my VMs 1000Mbps nics. Does anyone know if this is possible and how to do it? If not, does KVM support faster nics because at

We're looking at using windbind and AD for our user account details but have run into a small snag. All user accounts in AD are upper case but our linux accounts are lower-case. Is there a simple solution we've overlooked? We really don't want to have to hack this...

We have a 10Gbps connection to our server so I need to be able to create VMs using the faster e1000 nics instead of the default Realtek 100Mbps ones but I''m not sure how to go about it. Is there a walkthrough or "howto" or can someone point me at some simple instructions? I''m using xen-3.0.3-105.el5_5.5 and Centos 5.5 kernel 2.6.18-194.32.1.el5.centos.plusxen VMs are

I have nic bonding (mode=802.3ad) setup on 2 servers, both running Centos 5.5 In the "Active Aggregator Info", on one reports 4 ports - which is correct - but the other only reports 3 ports. It''s always eth0 that shows a different aggregator ID. Changing the cables around so it hits a different port on the switch makes no difference. The switch is correctly configured for the

This may be more of a general linux question but is there a simple way of preventing users from creating symlinks to or from certain directories? I have a /scratch dir that's a single 27TB volume and I don't want users linking their home dirs as there's a chance it will screw up our external backups. Is this a job for SELinux? Any ideas? Thanx, Russell

For a high-performance system (64-cores, 512GB RAM, 5TB local disk, 110TB NFS-mounted storage) is there any advantage of dropping lvm and mounting partitions directly? We're not planning on changing partition sizes, but if we did we'd probably do a full rebuild. Has anyone done performance testing to show that lvm isn't crippling I/O? Thanx, Russell

I came across an old post comment yesterday (from http://echenh.blogspot.com/2010/04/how-to-extend-lvm-on-vmware-guest-os.html ) discussing the "hack" of LVM on Linux VM guests and whether it's better not to use it to simplify disk management. I've re-posted the comment below, does it sound reasonable? Is it better to not use LVM on Linux VM guests? --Russell

Hi, This is semi-OT, but is Centos-related. I'm looking for an IPTables GUI to help us with our expanding network configuration. I know there's plenty out there, but most of them seem to manage the firewall on the computer on which they run, or only handle one firewall at a time. I need one that can easily manage multiple firewalls from some sort of central location/repository, i.e.

hi All, A fault on our SAN dropped us down to a read-only filesystem and after reboot, we have an "Unexpected Inconsistency" and I am being instructed by the boot to run fsck manually without -a or -p (this was after I think processing around 15% of the filesystem) The specific message is "inode 27344909 has illegal blocks" I recall running fsck some years ago on smaller

Is there a document available that gives a clear description of the layout of data in a version 2 .RDA file. I have a free program (http://www.vsn-intl.com/genstat/downloads/datald.htm) (Windows/Linux/Sun MOTIF exes available) that reads and writes a wide range of file formats, and have been requested by my users to add R to this. It already does S+. Regards, David

Hi, I would like to contribute to the CentOS Wiki page http://wiki.centos.org/AdditionalResources/Repositories I manage a repository of bioinformatics RPMs at AgResearch built with CentOS 6, which we have just published, and would like to add details of it to this page.

Hi, Is it possible to have multiple graphics windows in R? I am running a function that plots 12 graphs and currently I'm using par(mfrow=c(3,4),..) etc but ideally I would like to have the output in separate graphics windows.

Oops, I just missed the python part. Does mod_python have similar options? Or how to stop other users to run python scripts in some directories?

Hi all, Recently, after doing some maintenance on one of my servers (Centos 5), I rebooted. On reboot, it didn't find the SAN disks at all, and after some poking around in maintenance mode, I discovered that it couldn't find the Qlogic module. It turns out that /lib/modules/<kernel-version>/modules.alias, modules.dep and such were all empty or just had their header comment lines.
