Now I made an upgrade using 4 SATA II disks connected to a promise = TX4310 Raid controller. Defining a RAID5 a bios level, starting the server and building up the = Raid at OS level: # atacontrol create RAID5 32 ad4 ad6 ad8 ad10 # bsdlable ... # newfs ... =20 And now I have a functional Raid named ar0. =20 At boot time the bios told me that even at this level the raid in = initializing - world seemed to be ok. =20 Now I tried to prove Raid function and disconnect one disk. Theoretical data is covered by the rest of 3 ... but after I get the = system message that one disk has been disconnected the maschine stopps = working. Told me: ar0 raid 5 degarded after a fw minutes no input is possibble.=20 =20 =20 Even after reboot=20 .... ar0: disk0 Ready ar0: disk1 Ready ar0: disk2 Ready ar0: disk3 down no device found ... end of work =20 No single user mode or other starting option seemed to work. I have no chance to rebuild the raid via atacontrol. =20 Any hints? Raid without reliability doesn=B4t make sense! Regards =20 Dietmar=20
