problems with Pool I/O error

[jgreco]

No not Flashed. I asked for a While if it some difference between the Raid and nonraid Firmware. But nobody know this...

There's an entire sticky dedicated to the topic. Nearly every post where a user asks about the 9211-8i or M1015 has a reply with someone saying "Be sure to flash your card to IT mode." EVERYBODY knows the answer to this question if you only take a few minutes to read what's readily available on the subject.

If the pool is working fine (meaning you haven't done and CLI stuff behind the scenes), you can remove both the Cache and Log using the GUI.
