Hello CentOS list, I have a requirement that I need to use encryption technology to encrypt very large tar file on a daily basis. The tar file is over 250G size and those are data backup. Every night the server generated a 250G data backup and it?s tar?ed into one tarball file. I want to encrypt this big tarball file. So far I have tried two technologies with no success. 1) generating RSA 2048

I would rather work on single files or tars on directory basis. Using a single big file creates a very "large" single point of failure. Or use an encrypted file system (of course, also a single point of failure, but probably better handling). Kai

Hello Everyone, We are using CentOS 5 system for certain application. Those are VM guests running in VMware. There is datastore issue occasionally, causing all file systems becoming read only file systems. So application stop working, and opened files cannot be written either. We cannot even ssh login to the system. Typically we had to power cycle the VM. We are trying to add reliability to the

Hi, I am recovering a CentOS 5.4 system. I've copied all partitions into the recovery system. I've installed grub boot loader. However, the original system is using /dev/sdb1 for root (/), while the recovery system is using LVM (/dev/vg0/lv1) for root (/). When recovery system boots, I got the panic error: * Mounting /dev/sdb1 on /sysroot * Mount: mounting

Dear All, Below question has been puzzled me for a while, and don?t know if anyone has experienced such puzzle: You have an external array attached to a physical hardware. The operating system is CentOS 5. The file system is created on top of LVM on external array & mounted. The CentOS 5 can see the array controller, and manage all LVM configuration, etc. There is data stored in that

Hello All, I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system. I usually use dump/restore commands. However, I?m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure? Thank you, Xinhuan Zheng

Hi All, I have a Quantum scalar i40 tape library. I need to configure it to TWO tape partition libraries, e.g., library_a and library_b, so that each library has its own tape drive. Then connect this physical tape library to two different CentOS servers so that each server can see its own media changer and tape drive. I once had a successful configuration on one host but NOT on the other. One

Hi everyone, In my environment, we heavily rely on Hiera to parametrize our modules. Like the Puppet code, I would like to version-control the Hiera .yaml files. However committing passwords in plain text to GitHub seems really odd. So I would like to make you aware of one of my side-projects called Raziel. https://github.com/jbraeuer/raziel/ http://bit.ly/raziel-slides While there is one

Though I can not answer OP's question, I have question of my own. Is this really routine (often) task for Linux sysadmins? I used something like that to replicate cluster nodes in the past, but kickstart would be routine task for

Hello, I have data which I have arcsin transformed to analyse. I want to plot my data with error bars however as my data is back-transformed my standard errors are uneven. Is there a simple way to draw these asymmetric error bars in R? Thanks for your help. [[alternative HTML version deleted]]

We are running tinc (v. 1.0.26) in switch mode with bmx6 (another mesh protocol) running on top of the tap0 interface on about 25 devices. The asymmetric routing of UDP packets is causing my firewall and I presume others to drop some of the packets, since there are no outbound SYN packets originating from the device running tinc. Is there any way to mitigate this issue besides enabling tcponly
