similar to: Filesystem backup?

Hi all. I currently have a problem. I try to make a backup of a running / filesystem to a second disc. I've read tha some people use rsync for it. I mount the second harddisc at /mnt/hdb1 and issue a command: rsync -vaHx --progress --numeric-ids --delete \ --exclude-from=asylum_backup.excludes --delete-excluded \ / /mnt/hdb1 Then I shutdown the system, remove the first disc and try

I have a Cisco 2600 which understands the "gsmfr" codec, which appears to be what Asterisk calls "gsm" -- at least it ends up using it. I also have a PSTN gateway which is speaking ulaw. When the 2600 calls through Asterisk to the PSTN, it negotiates the g711ulaw codec, but when the PSTN calls through Asterisk to the 2600, it seems that Asterisk is doing translation, and it

Hi All. I have a CentOS server: CentOS 5.6 x86_64 2.6.18-238.12.1.el5.centos.plus e4fsprogs-1.41.12-2.el5.x86_64 which has a 11TB ext4 filesystem. I have problems with running fsck on it and would like to change the filesystem because I do not like the possibility of running long fsck on it, it's a production machine. Also I have some problems with running fsck (not enough RAM, problem with

Hi all, I am wondering whether there is a small bug in the binom.test function of the ctest library (I'm using R 1.6.0 on windows 2000, but Splus 2000 seems to have the same behaviour). Or perhaps I've misunderstood something. the command binom.test(11,100,p=0.1) and binom.test(9,100,p=0.1) give different p-values (see below). As 9 and 11 are equidistant from 10, the mean of the

I have a few thoughs and questions about donating to Xiph that I hop you have a minute for. Here we go: == "Who donated what" list == As it seems we don't have a "Who donated what" list. I thought creating such a list could increase motivation to donate to some parties. What I currently have in mind would be to start listing donations from now on below the current content

Hi all. I am currently designing a server room. I would like to be able to draw a 2D (in the future 3D) project. Do you know any tools? Which one can you recommend? Best regards, Rafal Radecki.

Hi all. I am currently building a small test cloud based on Eucalyptus 2.0.3 and CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN. KVM is the default in CentOS 6 but I have read also many good things (for example PV guest machines, isolation between Dom0 and DomU) about XEN. Key factors from my opint of view are: - stability (which one runs more smoothly on CentOS?) -

Hi All. I have two running servers (drbd primary, drbd secondary). When there is a problem with one of them we switch to the second one. Currently on the /dev/drbd0 (it has /xxx ext3 filesystem directly on it) we have some filesystem problems (after fsck -n). I would like to correct these errors but the filesystem should be unmounted first (I would like to avoid it if possible). Is there a way

Hi all. I am working for a hosting provider in Poland. We are currently searching for an universal, extensible hardware platform which we would like to use in our server infrastructure. The platform should have: - possibility to install up to 32GB of RAM and at least 4 slots for it; - at least 6 SATA ports; - the possibility to use SAS disks; - at least one 1Gb/s network interface and the

Hi All. I plan to use virtualization in my production environment. I plan to use one of the following options: - KVM; - VMWare Esxi; - VMWare Workstation. I plan to install Windows 2008 as a guest. I want to use something like LVM snapshots for backups. Stability is also very important, the guest will be used as a production server. Which option could You recommend and why? Thank You very much

Hi All. I have a setup in which I have two servers serving nfs share. The nfs service is made highly available with pacemaker. When the primary server goes down the secondary starts nfs service. Service IP is floating between servers but they have NO "shared" storage/filesystem so NFS state/connection information in case of failover is lost. I have two clients. When the failover from

Hi all. I am thinking about installing memcached with replication, I've found http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not want to use client side "replication" (writing to two memcached nodes at the same time) and haven't found other solution. Are there any good, protocol

Hi All. I have installed Citrix XenServer. It's Linux-based virtualization software. Could anyone propose a good way to make backups of virtual machines (Linux/Windows) in it?

Hi all. I am currently thinking about monitoring a network link (bandwidth, latency, packet drop). I have a centos server which is connected to providers network through a switch. How to test the link? Should I: - use ICMP to ping gateway and collect staistics of time/packet loss/etc. - use software like here: http://www.cyberciti.biz/faq/linux-unix-windows-monitor-outgoing-bandwidth-latency/

Hi All ;) Is there an option to compact large mbox files from the shell? I did not find anything in google, I have some very large constantly updated mbox files and would like to know if they can be made smaller with any tool. AFAIK mutt does such operation when for example an email is deleted but I am curious if there are other options. BR, Rafal.

Hi All. I am trying to install some software. Part of its installation is an invocation of command similar to: # sudo -H -E -u postgres /bin/bash -c /usr/bin/python2.7 /bin/bash: /usr/bin/python2.7: Permission denied >From my perspective: # ls -l /bin/bash /usr/bin/python2.7 -rwxr-xr-x. 1 root root 960376 Jul 8 2015 /bin/bash -rwxr-xr-x. 1 root root 7136 Oct 11 2015 /usr/bin/python2.7

Hi All ;) I need a good tool to backup whole system on block level rather than file level and easy to use. I currently need to backup to an USB disc (50+ GB of data) a system and then reinstall it. In the future if needed I will revert to the system from backup ;) What can you recommend? BR, Rafal.

Hi All. I've used syslog-ng for some time. I like it. I have a project in which I need to choose a central logging solution. What are your experiences with rsyslog? Is it more complex to setup than syslog-ng? Or maybe does it have some additional features? I am also thinking about using some gui tools for log parsing and graphing. May be proprietary/paid. Any suggestions? Best regards,

Hi All :) I need to check and possibly update openssl on my fleet of servers. I would like to avoid reboot if possible. I think that I can: - update openssl version with yum - check all daemon processes which are constantly running in the os, for example for sshd something like ldd `which sshd` | awk '/\// { print $3 }' | grep crypto | xargs strings | grep -i openssl to verify if the
