Myricom 10GE install breaks mdadm autodetection
System: iX Systems SuperMicro-based 2U server 3Ghz Dual Core Intel Processor, 4GB RAM
Distro: Fedora Core 7 Before: 3 SATA disks. 160GB sda contains OS, swap non-raid 2*750GB sdb, sdc each configured as a single type fd partition Raid 0 array created across sdb1, sdc1 and was working, with autodetection fine. After: Installed myricom 10GE card System boots fine. mdadm -A /dev/md0 /dev/sdb1 /dev/sdc1 will start the array with no errors. mdadm -A /dev/md0 --scan fails claiming "no devices for md0" If I start the array by hand, it is readable and the FS is in tact. I have added lines to mdadm.conf to specify the physical devices, but, that hasn't helped. I have not yet tried removing the Myricom card to see if that resolves the issue, as I would prefer to get this all working together. Unfortunately, I can't hand-assemble the raid volume in maintenance mode and then get the system to come the rest of the way up because when I exit maintenance mode, it reboots. Given that I'm able to read the array if I specify the device, I expect it must be possible to fix the autodetection, but, I have no idea how to do so. Any tips/pointers greatly appreciated. Thanks, Owen |
