Hello,
So recently (about a month ago), one of my volumes reached 80% utilization. I did not get a warning via email from freenas, but I noticed that access to the pool was slower than usual, so I logged in to freenas and noticed the yellow light sign indicating that the pool had reached 80%.
I did not have a chance to delete some content to free up space since I had reached 85% in the past without noticeable issues (other than degraded performance) so being at 80% didn't worry me much.
Then a few days later, I went back to freenas and the light was green again. I checked the volumes and the most filled one was at 73%. I then cleaned and deleted some stuff. Right now, it is at 71%.
The problem is that since the pool reached 80%, performance during movie playback is horrendous. The playback is fine in itself, but every 15 to 20 minutes, it locks up (stops) for several seconds (up to a minute) while buffering, and the hard drive caddies on the server are being lit up either in a sequence (hdd1, hdd2, hdd3, etc for all 8 drives), or all flashing heavily at the same time until playback resumes. No need to say, this kills the experience.. I did not used to have this issue in the past, and nothing has changed in the way the server is being utilized (connected clients via nfs, etc). In other words, workload has remained similar in the last 2 years or so..
Attached are some screenshots captured for a period where I experienced a lockup so significant, Kodi gave up playback and quit!
Some server data:
Supermicro X7DBE+
48GB DDR-667 RAM
2x Xeon L5420 quad cores CPUs
2x IBM M1015 HBA
Mixture of 8 SATA2 or SATA3 drives
Gigabit connection
No LAGG
I hope someone can shed light on this.. Is it caused by fragmentation?
Thanks
