Hi, I had to reinstall linux over the week-end and made the switch from Gentoo to Xubuntu 10.10. Since then, everytime the computer reboot,s the order of the drives changes making the use of my RAID array very difficult. I tried writing udev rules but they are not followed on boot. charles@ottawa:/etc/udev/rules.d$ cat 80-local.rules SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750640AS_5QD0ZEL6", NAME="sda" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750330AS_3QK0A55K", NAME="sdb" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750640AS_3QD1BKH4", NAME="sdc" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750330AS_3QK08ZAR", NAME="sdd" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST31000528AS_6VP053RH", NAME="sde" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3320620AS_6QF1A82N", NAME="sdf" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750640AS_5QD10GFJ", NAME="sdg" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750640AS_5QD0ZMT2", NAME="sdh" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750640AS_5QD0VDLG", NAME="sdi" SUBSYSTEM=="block", ATTR{ID_SERIAL}=="ST3750640AS_3QD0AF55", NAME="sdj" What else can I try?
