hard drive causing trouble with software raid array
i'm setting up a file server with an older asus mother board and a promise ide card.
i've got debian installed on the primary master - hda, and there are 3 320 gig ide drives on the ide controller - hde hdf and hdh.
I've got mdadm installed and created the array with the following command
end_request: I/O error, dev 21:40 (hdf), sector 312572151
or
end_request: I/O error, dev 22:40 (hdh), sector 312572047
errors coming up which causes the array to drop hdf and run in degraded mode.
I'm not really sure how to proceed at this point. all three of the drives are brand new so i dont think that they are the problem. the IDE card was used so i suppose it could be the source. The mobo is probably the weakest link... it seems that the secondary ide channel is dead, but other wise works fine
Promise controllers suck in Linux. The kernel developers added a lot of work arounds to get Promise controllers to work and they still have problems. I recommend using Highpoint Rocket133 or buy a 3ware card. I do not recommend setting up RAID-5 if it is a single processor system. RAID-5 consumes a lot of resources, so I recommend at least a two processor system. It is better to place one drive per IDE controller instead of three on one IDE controller. Do not use Seagate and Maxtor IDE or SATA drives for long term use like in a RAID array.
I do not know if the file server is for home or business. You may want to set up multiple RAID-1 and add them to LVM or EVMS. When you need more space, you can add more drives. You still get reduntancy but you also get infinite space.
