Hi All, I am quite new to RAID (please forgive if my questions are stupid) and I tried to read almost all papers (HOW-TO) that I was able to find on tldp.org but I still have some questions, I will split them in different emails. I would really appreciate if someone could answer my questions or if someone could give me a good link. For this setup I am using a RH 7.3 with a 2.4.20-18.7 kernel. 1) During boot time, when md is trying to autodetect a RAID array before the root filesystem is mounted, I get the following error when kmod is trying to load md-personality (someone know what this module is for ?). ========= Jul 9 15:28:29 mekare kernel: md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27 Jul 9 15:28:29 mekare kernel: md: Autodetecting RAID arrays.
