mdraid on top of mdraid
by Emmanuel Noobadmin 22 Mar '11

22 Mar '11

Is it possible or will there be any problems with using mdraid on top of mdraid? specifically say mdraid 1/5 on top of mdraid multipath. e.g. 4 storage machines exporting iSCSI targets via two different physical network switches then use multipath to create md block devices then use mdraid on these md block devices The purpose being the storage array surviving a physical network switch failure.

> Since your exporting the storage as iSCSI, the host machine will see > it as a raw disk, irrespective of how it's setup on the exported > server. So, yes, you can do this. Sorry for my ambiguity, I meant that mdadm would be on the host machine. e.g. Using just a 2 node, raid 1 situation Storage 1 -> Disk exported on 192.168.1.10, 192.168.2.10 Storage 2 -> Disk exported on 192.168.1.20, 192.168.2.20 Host -> mdadm multipath md0 = 192.168.1.10, 192.168.2.10 -> mdadm multipath md1 = 192.168.1.20, 192.168.2.20 ---> mdadm raid 1 md2 using md0 md1

Is there something odd going on? The question about the errors in mcelog just showed up *again*, and it's the original that I answered this morning. The question about something - was it the md? - original seems as though it's shown up more than twice today, with the same timestamp, I think. Is anyone else seeing this, or is it my host's mailserver? mark

syslog.conf - how to redirect messages by a program name?
by Alexander Farber 21 Mar '11

21 Mar '11

Hello, the "man syslog.conf" explains how to filter syslog messages by facility (auth, authpriv, cron, daemon, kern, ... ) or by priority (debug, info, notice, warning, ...). But how could I redirect messages by a program name, like "drupal" or "php"? For example I have in /var/log/messages: Mar 20 04:20:44 mysite drupal: http://mysite|1300594844|page not found|66.249.66.193|http://mysite/sites/default/files/pictures/picture-7133-1300462418.png||0||sites/default/files/pictures/picture-71333-1300462418.png Mar 20 04:20:50 mysite drupal: http://www.mysite|1300594850|page not found|93.158.148.31|http://www.mysite/viewtopic.php?f=5&t=42639&p=165661&sid=73944439da6ca3054a40f464ce97a628||0||viewtopic.php but I would like them to go under /var/log/drupal (and I'll rotate them later by adding a file to /etc/logrotate.d ....)

21 Mar '11

I want to create bash script to have a zip copy from a website running on linux /var/www/htdocs/* local on the same box on different directory I am thinking to do a local backup using crontab (snapshot my web) tar -cvzf /tmp/website-$(date +%Y%m%d-%H%M).tgz /var/www/htdocs/* This command will create a file /tmp/website-20110101-1459.tgz I want it run on daily basis and to keep the last 5days backup on the box and remove older version than 5days. Can you point me out. Thanks madunix
