Howdy I have a Dell PowerEdge 2950-III (BIOS: 2.6.1) with a PERC6i (FW: 6.2.0-0013, DRIVER: 00.00.04.08-RH2) that is built into a single RAID5 array happily running CentOS 5.4, and has been running happily for some time. We use it to dump impressions data and DB snapshots to.
(Possibly useful info: we use LVM and we're at kernel 2.6.18-164.11.1.el5) I recently installed a RockerRAID 2314 PCIe card ( http://www.highpoint-tech.com/usa/rr2314.htm) and got an eSATA JBOD chassis (http://www.rackmountmart.com/html/SA4001.htm) to add a little more cheap storage for "less important" data. Brought the RocketRAID's BIOS up to date (v2.5), built the latetst driver from source, loaded it and everything was peachy. I built a RAID5 array with a spare on the live system with the Web-based Management System (v1.4-10), formatted and mounted it. Yay. We hadn't begun really using the volume yet when I rebooted the machine a few days later for a memory upgrade and it hung on boot at the following screen: Booting 'CentOS (2.6.18-164.11.1.el5)' > root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /vmlinuz-2.6.18-164.11.1.el5 ro root = /dev/obnas/root [Linux-bzImage, setup=0x1e00, size=0x1d6b1c] initrd /initrd-2.6.18-164.11.1.el5.img [Linux-initrd @ 0x37cb5000, 0x33a982 bytes] So, I power cycle the machine, went into the Card's BIOS and delete the array and it booted fine. I think the RocketRAID is confusing GRUB or something like that when it has a bootable volume. So I went through the all the BIOS settings, boot orders, array settings on the RocketRIAD BIOS etc.. no luck. I have a ticket open with HighPoint (makers of the device) but it is the weekend so I don;t expect a reply for a while. I've got a crazy week up ahead before I am out of the office for surgery so I want to try to get this done. My gut feeling is that it is a common enough problem with add-on cards that have their own BIOS and i am either dense or an awful researcher. I would greatly appreciate anyone's insight.
