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

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

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

Hello, Today I searched redhat official portal and learned that Sendmail is considered deprecated. By default, CentOS 7 will use postfix as MTA. I need good advise on what it means to us. We are CentOS customers. We use that operating system for quite a few years. We rely on Sendmail for years for us to relay large quantity of emails to our customers for marketing purpose. We build our additional

Hello, We need to manage isolated network environment so that even though host name and ip address could be same, but they are located in isolated network environment so that?s not a problem. However, that would be very challenging to build a server in such an isolated environment. For example, we could do kickstart to build a server in non-isolated network environment, but for isolated one, we

Dear All, I want to create a CentOS 7 VMWARE VM. I need to install various Runtime libraries, e.g., Tomcat, into the VM. Once all looks good, then I want to make a Custom Image of the entire VM. Later I want to load this Custom Image to a physical HW, so that I don?t need to go through all kinds Runtime installation. Does anyone know how to handle creating a Custom Image and Load to physical HW

By default, CentOS 7 will use postfix as MTA. That was an excellent decision I welcomed the day RedHat made it.

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

All commands return a value, usually 0 if run properly. For instance, try: $ ls && echo "done" $ lsd && echo "done" The echo command is only executed if the ls command exited successfully. If one did not add the echo command with the && after a command, how can he determine if the command exited successfully? I have a particularly troubling script that

Hi, I have to port ALTQ(Alternate Queueing) software form the FreeBSD to QNX. It''s more like a bandwidth manager. Since I am new to this domain, any kind of help will be useful. I have many doubts like * What exactly is a bandwidth manager * Where will it sit in the OS * How will it be implemented. Thanks in advance Prajith.
