Hey, I've been using ZFS for over a year since, and never had any problems. I have 4 x 4TB disks that are hardware raided into RAID5 and seen as a large 12 GB disks which I then created a ZFS drive.
My drive works great, but I have noticed that performance is now severely degraded for writes, and it has been getting worse over the past few months. I don't do a lot of read/writes/delete and rewrites; the drive is mainly used to archive video materials.
Is this a known feature overtime with ZFS drives, or with drives that are getting near their capacity (I only have aroud 860 GB left on the 12TB drive)
What can I do to investigate further or to reset the drive back to it previous happy performance.
Thanks in advance,
Nick
