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.

Thanks,

When I copy 128MB size files using 64k page size no issues seen. When I
tried to copy 1.8 GB file with 64KB page size support I am seeing the
following errors. Any clue what could be wrong.
 
Errors 1:
EXT3-fs error (device md0): ext3_new_block: Allocating block in system
zone - blocks from 65533, length 1
EXT3-fs error (device md0): ext3_new_block: Allocating block in system
zone - blocks from 65534, length 1
 
 
Errors2:
EXT3-fs error (device md0): ext3_readdir: bad entry in directory #2:
rec_len % 4 != 0 - offset=0, inode=3040

 
Thanks in Advance,
Marri
