Hi. I have had some trouble with the machine I want to have as a file server. After having let the "get raid up and running reliably" project lie dormant for some time, I tried again this Friday. After connecting the disks, the status was the following: 4 out of 6 disk in a raid6 setup were recognised (see log-1). I was able to mount the volume when the machine was finished booting. I then added the two missing disks with mdadm, one of them started rebuilding and the other one were not recognised in some way (log-2). The rebuild of the disk was successfull (log-3), but later some errors occured, see log-4 below, and now only three disks are left in the array (log-5). Are these errors related to Tejun's recent statement "Sil3112/3114 are now virtually the only controllers with occassional and unresolved data corruption issues."? Disks sda (hosting root file system for os), sdb sdc and sdd are connected the motherboard while sde, sdf and sdg are connected to a controller card using 3114: 01:04.0 RAID bus controller: Silicon Image, Inc.

So I do believe that this is not disk errors. The machine is running Fedora 10 with kernel 2.6.27.41-170.2.117.fc10.x86_64, mdadm updated to the latest 3.0.3 release from Fedora 12. Unfortunately I have too little time to do any thorough investigation on this. My plan is to upgrade to Fedora 12 and maybe build some latest kernel to see if that makes any difference, and if not (or probably in any case) swap out the 3114 card with a Promise TX4 card instead.
