hi everyone
in my freenas server, each disk is on Raid0 Hardware Raid P410i separate raid0 disk present to zfs.(i know this is not recommended)
when I want get disk serial number for fail time, all disk have same serial in freenas.
but confusion is that :
smartctl -a /dev/da1 ( or da2 and so on)
i see all serial number are same and SMART support is: Unavailable - device lacks SMART capability.
but when i run " smartctl -d cciss,0 -a /dev/ciss0"
i get correct serial number as Logical unit id and SMART support is: Available - device has SMART capability.
1- How Can I get disk serial number for replace in failing time?
2- is SMART functioning properly for failing detection? if no, what is alternative solution?
3- in my implementation how can i find failed drive?
thanks
