Hi All,
I can't access my main dataset which consists of 3 x 2Tb disks configured as raidz1-0.
Looking at the logs 1 disk started logging
But showed nothing was wrong in the gui. Some posts I read state this is normal behaviour but seems a little dangerous to me as this issue is easily missed especially if you dont have alerts configured to send to email. More so if another disk starts flagging the same kind of errors then following occurs!
This all happened whilst i'm away :( 2 of the 3 disks appear failed and the other isn't looking good. So; a couple of questions

Code:

This all happened whilst i'm away :( 2 of the 3 disks appear failed and the other isn't looking good. So; a couple of questions
- does FreeNAS 9.10 still not show in gui if a disk starts logging smart uncorrectable sector errors etc
- As a learning exercise, might the dataset be recovered somehow or am i'm going to have to restore from backup?
