Re: 64k Page size + ext3 errors

I am using HW accelerated XOR engine for RAID-5 . I am seeing EXT3-fs
errors when I use 64K page size. When I use 4K page size I don't see any
issue. As many of you know, we will get better performance when we store
bigger files like videos.

Do you think it is specific to the filesystem on raid-5?  Have you tested
w/o md?  I'd be a little surprised if the problem is at the raid layer (so
cc'ing the ext3/4 list), but maybe you tested that already.

Which arch is it, and which kernel?  How big is the filesystem?  With full
geometry information it might be easier for someone to reproduce & debug.

Marri, can you post your XOR driver the problem may be there.

Thanks,
Dan
