After adding disks to vmware clients or new luns to san, das services its useful to get the linux os to rescan the scsci devices.
echo "- - -" > /sys/class/scsi_host/host0/scan That’s it. You can look for log messages at “dmesg” to see if it’s working. You can also look at /proc/scsi/scsi to see if the devices are there. There is also the “lsscsi” command that will show you the know devices plus the device entries that point to those devices (very usefull).
After trying to import massive db dumps and it taking for ever i came up with a script to chop up a mysql dump at the table level. This allows me to import the dumps table by table, allowing for a multi threaded import rather than a single threaded import.

I thought to myself what’s the best way to back this up, dd + nc was the way to go i thought.
My last article covered by original mail setup after some usage i have tweaked it even more so i have to do even less.
I have now introduced imapfilter that can move messages to the correct mail folder before i run offlineimap.
First you need to setup ~.imapfilter/config.lua
