similar to: rsync many small files

I have an existing in-production LAMP server running Centos 5.1. It uses physical partitions on top of hardware RAID1, having / /home /var and /boot on separate partitions. We have a near-identical system I am thinking of bringing in as a DRBD/Heartbeat companion. One solution may be to use csync2 [http://oss.linbit.com/csync2/] on /etc and /usr/local (the only areas that will differ from

WE have a centos 5.3 install, and our server is keep getting hacked. We see load averages of 500+ and see people from all over the world logging into our server (used last). Is there a good place to start to avoid these kinds of things? For example, here is what I already did. Open up sshd port only setup iptables to only accept port 80 and 22 No FTP No other ports are allowed according to IP

Dear Daniel, Klaus I've try that before But because of how samba work on the files. The Advise is No Without CTDB, you will just shoot yourself on the foot...

Hi, I was thinking about bidirectional sync of sysvol and i've a question: ?What about DRBD?. You can create a disk partition in every node, create a DRBD cluster and then mount that partition on sysvol folder. The sincronization is bidirectional and in real time. For now i've not tested this option, but i've plans to start some tests. What is your opinion about this? Greetings!!

I try not to post my real name on the internet. I'm basically asking for commit access for user sub page space for formatting, & staging of documents for management review. When I'm actually @ linbit ill probably start the motions to have an official account something like "linbit-usa" to publish the works under. I'm used to mediawiki, moinmoin wiki is new to me.

Good day! I set up a domain controller AD (PDC and BDC) by Samba 4 on Debian Wheezy. I took a configuration from examples. After setting the PDC I configured a second controller(BDC) and connected it to the domain. On PDC server has created a network folder for portable user profiles and synchronized it to the BDC through csync2 . My problem that the PDC and the BDC on the same user names has

I''ve got a client demanding the use of HP DL380 G5''s, for various historical reasons, for a server room. I''m going nuts trying to figure out if the available CPU''s for them support VT, so I can avoid building them a separate Windows box. Unfortunately, the local web proxy is overloaded, so actually browsing the JavaScript/image loaded web pages for HP is

Hello, I am currently running R on ubuntu and everything is working perfectly fine. However, I would like to connect to R via Windows using Eclipse StatEt plugin. Is this possible to do? or do I have to have a version of R running on Windows also? I prefer to have Linux do the heavy lifting and Windows Eclipse to be a sort of GUI. Any thoughts?

Hi, I want to combine all the above mentioned technologies. The Linbit pages warn not to use the drbd: VBD with HVM DomUs. This page however: http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en (thank you Jean), simply puts two DRBD devices in dual primary mode and starts Xen DomUs while pointing to the DRBD devices with phy: in the DomU config files.

I wonder if someone can point me in right directions. I have two dell servers I setup iscsi so I have four 2 tb hard drives and i had used lvm to create one big partiton and share it using iscsi. How I go about assigning sections of iscsi for virtual hard drives . should go about assigning Should I export the whole 8TB as one iscsi and then use lvm to create smaller virtual disk. Or should I

We have about 800 CentOS 5.2 servers and our university. We use NFS being served from over 10 NetApp frames. We use autofs for to mount up our partitions. There have been times where we can't cd into the directory. It says the directory does not exist. On some servers it works but on others it does not. Typically we restart amd and autofs to resolve this issue. But sometimes it does not even

I apologize if this has been asked before, but couldn''t search the forum-mailing-list bridge. It seems the search feature is currently disabled.

We use Microsoft Outlook heavy at school but our backed is CentOS. I use echo "Foo" | mail -s "subject" addr at unc.edu a lot. Is it possible to change the priority to High so Outlook will understand it? The priority meaning the email will be sent to the normal email queue but on Outlook it would have the exclamation point. TIA

Hello All, I have been using rsync to backup several filesystems by using Mike Rubel's hard link method (http://www.mikerubel.org/computers/rsync_snapshots/). The problem is, I am backing up a lot of ASCII .log, csv, and .txt files. These files are large and can range anywhere from 1GB to 30GB. I was wondering if on the target side (the backup side), if I can use some sort of compression. I

Hi, I'm very grateful for the new ProxyJump option. It helps tremendously! One small question I'd like to ask, though: Is there a way to skip one (mostly the first) jump host if the machine is in some specific network? For example, from home, I (resp. a shell script) need to jump to the office's server, a customers' login host, and then to the destination node; from the

I want to use rsync with a cloud based rsync provider to do off-site backing up of a large (1TB) dataset which consists of 32 million+ files spread out in 300 directories. So the amount of files in any one directory can be quite large (upwards of 2 million). Rsync doesn't seem to cope with this well - even doing local copies in a directory with several thousands of files takes a long time to

At my physics lab we have 30 servers with 1TB disk packs. I am in need of monitoring for disk failures. I have been reading about SMART and it seems it can help. However, I am not sure what to look for if a drive is about to fail. Any thoughts about this? Is anyone using this method to predetermine disk failures? TIA
