Hi!
It is only rpool, no data, but of coarse configuration data. So there are no write-intensive applications writing to the drive, only log. Not even swap or dump, they are on different devices. It would be nice to know if there was a way to tell wether it is the drive or the port, though...

SSD are famous of failing at the same time if they were installed at the same time. Also if you are using the pool by write intensive application SSDs can die quick. Depending on the drive you should be able to look at the Erase Count attribute from the SMART information. The value should be above a 100, if under some data loss is possible, if "0" the ssd will stop working, all this dependence on the manufacture. The easiest thing will be to replace the drive and see if the errors come back. Good Luck Yavor Tomov On Thu, Jul 2, 2015 at 8:55 AM, Johan Kragsterman <johan.kragster...@capvert.se> wrote: Hi! I got a degraded rpool, consisting of a mirror of two SSD's. I feel unsure about if it really is the SSD that have failed, since it is enterprise grade and haven't been running that long I would like to know if there is a way to figure out wether it is the SATA port or the SSD that have failed.
