Andrea, I'm using UYOK, because I wanted the megaraid_sas driver. I don't know if that's in the BOEL kernel, though I suppose I could experiment and find out. I created a /dev/zero exactly as you described, but it didn't make it into initrd.img. I don't know why not. On the chance that there was a mknod command at that point, I added this code to the master script, just before "Wipe the MBR clean": # Make a /dev/zero. logmsg "mknod -m 600 /dev/zero c 1 5 || shellout" mknod -m 600 /dev/zero c 1 5 || shellout It looks like this worked. The partitioning went OK. Thanks for your help. I plan to drag another node up from the warehouse, and see if this setup will correctly partition a brand new PowerEdge 1950. -- Carl Benson, PHS Linux SysAdmin (206-667-4862, [EMAIL PROTECTED]) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
