It was giving read errors for several months.

 

Backup, replace both drives and create a new volume.

One of the disks (the last in the array) removed itself from the raid (actually is showing a capacity of 4gb instead of 3tb), then when I tried to replace it to rebuild the raid a second disk started having problems. Now it is counting i/o errors. The RAID drive still mounts, but there is no way to rebuild it.

 

The disks (5) are allocated in a sata cage and they are directly connected to the sata controller of the mainboard.

 

Here I attach my tech report.

Thanks for your help in advance.
