When my ZFS pool got to around 90% capacity, I started receiving the "[Errno 28] No space left on device" error when writing to my ZFS pool. I tried moving files off the pool, reducing the storage capacity to 88.5 %, yet this error persists. I later noticed the Minimum free space setting was set to 10%, which could explain the original error. However, I have since tried updating that setting to values less than 5%, but the No space left error persists. I'm not sure what could be the cause at this point.
This pool is configured to my Array so that mover moves files from the ZFS pool into the Array. Here is a screenshot providing more info on my share configuration.
I'm wondering if this error may have been a result of my moving content from my pool into the Array outside of the mover task. I don't know if that is supported. I did this because the mover task seems to either be broken since the 6.12 upgrade or is very slow when running against the ZFS pool. I had the task running for almost 2 days and saw no sign of anything actually being moved.
Any suggestion on how to resolve this would be greatly appreciated.
