I have not paid attention to this thread. So, might be asking a stupid question... Are the disks from a system of the same platform? If not, maybe the byte ordering is different? I think I recall this as an issue with the 0.9 superblock, but I think it was not an issue with a newer superblock. Maybe it was just a feature request. Not sure. Anyway, mdadm supports "byteorder". man mdadm for more info. I have never used it. } -----Original Message----- } From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid- } owner@xxxxxxxxxxxxxxx] On Behalf Of Majed B. } Sent: Tuesday, September 22, 2009 8:14 PM } To: Sunpyo Hong } Cc: Robin Hill; linux-raid@xxxxxxxxxxxxxxx } Subject: Re: Raid 5 Issue, cannot recognize EXT3 File system. } } If you are sure that you have created the array with the proper order } of disks (They MUST be in the correct order!
