I have older systems out there that work fine, just for what ever reason would be great to upgrade from a C5 -> C7 (due to no longer supported) or C6 > C7 (for updated packages). Sounds like the upgrade tool is not quite an option... I was thinking... What would be wrong with any "easy" script that did the following: 1) Removed all packages with the --justdb option. 2) Import

Thanks Mr. Roth! That's nice and methodical. I do like how you can revert by simply remounting the previous directories. I'm going to try both. I'm still hopeful that a simple tar -xf server.tgz into the chrooted "/" is possible. At linuxquestions.org, one user suggests it can be done by exempting the following: /proc /sys /dev /tmp /var I'm thinking the tarball thing

I want to move all my OS, services like Apache configuration and application (web server) files and folders to another brand new server. Both servers are running on Centos 7. i want to clone everything. My questions 1- what is the easiest way to do this? 2- do I need to partition hard-drive of new server exactly as old one? 3- Is there any changes to make on new server after full migration? 4-

Hello all... I have a remote machine running C6. I desire to update it to C7. Not possible to be on-site. Can I copy the Everything ISO for C7 to the machine, mount -o loop C7.Everything.iso /media/cdrom then do a "yum upgrade" ? Will that work? The server is using software raid. Thanks Jerry

The objective is not to cherry pick updates, but rather to install a second system with packages that match the first system. After fine-tuning the installed packages and stripping out the

I manage a set of CentOS operations workstations which are all clones of each other (3 "live" and 1 "spare" kept powered down); each has a single drive with four partitions (/boot, /, /home, swap). I've already set up cron'd rsync jobs to copy the operations accounts between the workstations on a daily basis, so that when one fails, it is a simple, quick process to swap

Hi, I just found myself having to set up a new CentOS 6 system with a nearly identical configuration to an existing host, so I thought I would just 1. Do a minimal install to set up partitions etc. on the new system. 2. Create an image of the existing system using Clonezilla (http://www.clonezilla.org) 3. Run a Clonezilla restore on the new system. - as I though it would be a lot

I am trying to create a one line command that will: 1. Find all files ending in .conf 2. tar these over ssh to a remote server. I have reached this point in my trials. a. I can find the files. b. I can tar them locally. c. I can get a simple fileset tar'ed to a remote server over ssh using tar -zvcf - /some/fileset | ssh host.domain.tld "cat > /backup/tarfile.tar.gz d. I cannot

Hi, I am running the following command, it is "pulling" the files across from a read-only configured rsync server via ssh. The command runs as root and I use the -p option to preserve permissions but files with non-root owners are being created/updated as root owned. Can anyone explain whats wrong and if I can do anything to fix this? /usr/local/bin/rsync -r -p -e "ssh

Hi, my video sharing website (politube.org) that I developed with rails, runs on lighttpd/fcgi (I know it is obsolete by now) and is severely under load and regularly blocks because the lighttpd process chews up 50% of RAM (1GB). So now I want to move the system to a new server with 8GB, 64bit , Quad core processor (intel i7 920) but I am not sure if hyperthreading will really do anything better.

Hi, We have file readahead to do asyn file read, but has no metadata readahead. For a list of files, their metadata is stored in fragmented disk space and metadata read is a sync operation, which impacts the efficiency of readahead much. The patches try to add meatadata readahead for btrfs. In btrfs, metadata is stored in btree_inode. Ideally, if we could hook the inode to a fd so we could use

Hello, i have just migrated machine to xen server where only 2 cpus are available. I have copied config from machine where domU was located before. That machine had 4 CPUS (QUADCORE), current machine has 2 CPUS (1 XEON 2cores). I have forgot to change vcpus from 4 to 2 in config, but .. what really surprised me ... machine started . How it is possible? It was really slow alltought and not

Hi, I was able to implement T122p one port PRI and was able to call out, but I am planning to use TE412p (includes echo cancellation) 4 port digital card (PRI), I wanted to know can asterisk support 3 four port PRI cards (12 PRI connections) with proper hardware like dual core quadcore processor and 8gb RAM in one server? Also I was planning to implement using 64 bit architecture with Asterisk:
