I'm using the latest Opensolaris dev build (132) and I have my storage pools and volumes upgraded to the latest available versions. I am using deduplication on my ZFS volumes, set at the highest volume level, so I'm not sure if this has an impact. Can anyone provide any hints as to whether this is a bug or expected behavior, what's causing it, and how I can solve or work around it?
There is no doubt that it is both a bug and expected behavior and is related to deduplication being enabled.
Others here have reported similar problems. The problem seems to be due to insufficient caching in the zfs ARC due to not enough RAM or L2ARC not being installed. Some people achieved rapid success after installing a SSD as a L2ARC device. Other people have reported success after moving their pool to a system with a lot more RAM installed. Others have relied on patience. A few have given up and considered their pool totally lost.
