What are Reallocated Sectors?


Most ReadyNAS users have probably experienced it. Waking up, eventually checking email over a morning cup of coffee to find that overnight your NAS has sent you the friendly warning:

Error message: Reallocated sector count has increased in the last day.

Disk1: Previous count:0 Current count:4

Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.

So after clearing out the coffee you just spluttered all over your keyboard,  what are Reallocated Sectors and, more importantly, what are you going to do about them?

Managing your Music on your ReadyNAS

A primary use of home NAS devices is the central storage of, and access to, a media library. For many people a large portion of that library will be music, music that is also often being accessed by multiple applications: SqueezeboxServer, DLNA servers, iTunes etc.

It would of course be of great advantage if that music library could be managed directly on the NAS in a manner that all these other applications can access the same consistent metadata and cover art and I recently came across the application bliss, the aim of which is exactly this - a single web based tool for organising a music library. While it appears to be in the relatively early stages of development, with an initial early focus on Album Art management, it works very, very well and I'm keen to see how it develops.

I won't cover the functionality of bliss here, there are full detailed instructions on the bliss website, but here are some instructions specifically for installing bliss on a ReadyNAS device.

Backing-up via Rsync to a local USB disk

It is often desirable to use rsync to backup data due to the benefits it offers: true incremental backup, the ability to remove data from the backup that has been deleted in the source and rsync's support for verification of the backed-up data are just some of the advantages.

Below is an example of the backup settings needed to enable rsync to be used to backup a NAS share to a locally attached USB drive.
