Hi My name is Tarak. I got some problem with the XOR engine while creating the RAID array. The parity data is getting corrupted and my system is not able to recognize it and some how we are getting the hard disk error. I found the above issue is happening when I enable CONFIG_RAID_ZERO_COPY=y in my Linux configuration. Without this option everything is working fine. Following are the version details Linux : 3.0.34 GCC : 4.6.2 (GCC) ) mdadm : v3.2.5 I want to know the way to fix the RAID parity error. Please help me on this. Thanks & Regards Tarak Ramgopal Anumolu Security Solution Division SAMSUNG TECHWIN CO.,LTD Phone : +82-70-7147-8396 Mobile: +82-10-7249-8396 E-mail : tarak.a@xxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
