Hello.
This is what happened.

I installed an instance in drive E:.

Drive E: is part of a NAS.

Something happened with the NAS (I suspect it got disconnected).

Then I checked the alert.log and says (it is in spanish):

ORA-01157: no se puede identificar/bloquear el archivo de datos 1 - consulte el archivo de rastreo del DBWR
ORA-01110: archivo de datos 1: 'E:\BD\ORADATA\ORCL\SYSTEM01.DBF'
ORA-27047: no se ha podido leer el bloque de cabecera del archivo
OSD-04006: ReadFile() failure, unable to read from file
O/S-Error: (OS 38) Se ha alcanzado el final del archivo.

What could be a solution for such error?

Howdy, Stranger!
