Nas on BAFM

Linux NAS optimizations

Wed, 09 Jul 2014 20:04:40 +0000

Well, I recently had to flatten my archive NAS (well only the OS part … wheeeh). Since I didn’t have the chance to backup the old settings I had to do everything from scratch … And this time I decided, I wasn’t doing a script but rather the proper way.

I spent a while reading through the Internetz about the various settings until I stumbled upon a Frauenhofer Wiki entry. From there I ended up writing those udev-rules and the sysctl configs…

SFdisk - Partition table for 2TB RAID-Disks

So, when I create (or add RAID disks) I have this handy sfdisk template (I created once when I first added the 2TB disks):

# partition table of /dev/sdj
unit: sectors
/dev/sdj1 : start= 2048, size=3906793472, Id=da

So, if I wanted to add more disks, I’d just have to run the following:

3ware 9550SXU-8LP trouble

Wed, 21 Oct 2009 17:45:52 +0000

My home NAS, powered by a (used) 3ware 9550SXU-8LP, started behaving weird during the weekend. The box would boot one time, but if you’d reboot it again it wouldn’t come back up. Now, since I don’t have a monitor attached to it (I didn’t take the monitor with me when I moved), I needed to borrow one from work – I’m gonna buy a DVI-D to HDMI-adapter soon, since the 42" LCD-TV is right besides the NAS.
