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

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

Maybe one of you can help. We have set up a CentOS server so that each user who logs in via sftp will be jailed in their home directory. Here's the relevant sshd_config: # override default of no subsystems Subsystem sftp internal-sftp -f LOCAL2 -l INFO Match Group sftponly ChrootDirectory /home/%u ForceCommand internal-sftp This actually works great, but none of

Hi, I need to configure yum to limit the number of URLs going out for security reason. I don't find a configuration for include option. I do find an exclude option in /etc/yum/pluginconf.d/fastestmirror.conf. It would be impossible to exclude every url in this file. What is the best way to limit the traffic going out interest for yum? Is the local network repository a better way or does

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, 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

Beginning with my firat RedHat (it was somewhere around RedHat 5 IIRC) I always have been replacing venerable

Anyone having problems with logrotate and CentOS 5.4? Although I have /etc/logrotate.d/mail (contents below) to rotate my maillog file, it fails to do it automatically: /var/log/maillog { compress dateext maxage 365 rotate 60 size=+1024k missingok postrotate /etc/init.d/MailScanner restart endscript } ++++++++++++++++++++++++++++ logrotate.conf:

I'm noticing that logrotate's default configuration for rotating /var/ log/secure and /var/log/messages partially fails if root's shell is set to /bin/tcsh (via chsh). (Running on CentOS 4.4; logrotate-3.7.1-5.RHEL4). What seems to be happening is that the logrotate.d/syslog postrotate command runs: /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null
