1) I am planning a RAID10 setup with 4 hard drives. If one of them fails and I hotswap a new one in, will software raid[assume latest version kernel] rebuild it automatically?
2) I am going to be administrating a lot of servers. How will I know if a hard drive fails in my many servers? It seems the only way to check is to check manually or a customer raising a ticket[which is opposite the point of raid10 anyways]
Assume solusvm+billing situation.
1) No, software raid will not rebuild automatically, you will need to reactivate the mirror once the bad disk is replaced.
2) There are many monitoring programs f.e Nagios to monitor these kind of things.

SNMP, or something like Dell OpenManage on genuine Dell hardware. Do you not require a hardware RAID solution?
