Subject: RAID stride 32751?

I have an old, ~1TB ext4 filesystem.  Performance sucks (although I
don't really think this is ext4's fault).  But tune2fs says this:

Block size:               4096
Fragment size:            4096
Reserved GDT blocks:      960
Blocks per group:         32768
Fragments per group:      32768
Inodes per group:         8192
Inode blocks per group:   512
RAID stride:              32751

Is that 32751 a problem?  I'm not entirely sure what the raid
controller's stride is, but I doubt that it's 32751 bytes.

Thanks,
Andy
