[Linux-cluster] FS Block Size Limit

[Richard Mayhew]

Hi,

I tried to format our 4 GFS partitions with a block size of 8192 (twice
the default) to correspond with the default raw block size on the SAN's
LUN's to do some performace comparisons with no success. Any block size
1024*X < 4096 worked with no problems, anything larger than 4096 came
back with an error when trying to mount the file system.

Any idea as to why there is a limit set to 4096?

Thanks
