Re: RAID SYNC

[Avijit Pathania <foulplay@foulplay.org>]

Looks like you do not have DMA enabled. `dmesg |grep -i dma` to see if 
system recognized it and `hdparm -d /dev/hda` to check if it is enabled.
Check if your IDE chipset is configured in the kernel. Or usr 
/etc/sysconfig/harddisks to enable it using hdparm.

It should take around 30mins for it to finish resync.
