Hey guys,

 

I've had my massive unRAID setup (max'd out 24 bay server w/ 3 TB drives) for almost two years now running smoothly, thanks in large part to this forum. Recently things have started to really drag, dropping my read/write speeds to comical levels and even making the act of connecting to the server via AFP (our office is mostly Macs) via Finder a hit & miss process. Usually takes 4-5 login attempts from a user before the box will mount even with all green lights & acceptable temperatures across the GUI.

 

The only variables besides age are that we've slowly been adding 1-2 users/month (now up to about 18 concurrent users), slowly running out of overall space, and we've added a totally separate Raid 5+0 to our network in addition to the unRAID box, but these servers are only connected via a switch.

 

Some server specs below, along with a recent syslog file (broken up into 2 files). Any ideas for helping diagnose the apparent slow death of my server? Have I crossed a critical remaining space barrier that is causing the parity to drag or something?

Does unRAID have any known connectivity or performance issues once you get below 6% or 7% total remaining free space on the system? Just wondering if it's something as simple as that that's taking us offline.

Reiserfs is known to slow down in creating new files when disks get close to full.  This is not specific to unRAID, but any Linux variant where Reiserfs is in use.
