Using PM 8.5 on server 2003. HP prolient hardware 380 G4/G5/G6 and bl460 blades. smart array 5i, p400 etc. scsi and sas drives (depending on Gx model) We have two partitions, and sometimes we adjust these. Typically shrink d: part and then make the c: part expand the free space. We always do the procedure in two steps, first shrink d: then expand c: The process have been tried with PM installed or from a bartpe boot. The result is the same. The process finishes with no errors and the server is booting fine. Then after a while, minutes I believe or after a second boot - the c: partition becomes corrupted and the server craches or are not able to boot anymore (complaining about missing system files). Only way to fix it, is a full restore. Anybody have an idea on this? raid controller/drive issue?
