Maximum log stripe size

[Stéphane Doyon <sdoyon@xxxxxxxxx>]

Hi,

mkfs.xfs insists that the log stripe unit (-l sunit) must be
smaller than 256K.

See xfs_mkfs.c around line 1730:
        if ((lsunit * blocksize) > 256 * 1024) {
                fprintf(stderr,
_("log stripe unit (%d bytes) is too large for kernel to handle (max 
256k)\n"),
                        (lsunit * blocksize));
                exit(1);
        }

Can anyone please tell me whether this is really necessary?
Our SCSI RAID controllers would much prefer stripes in the order of 1MB.
And the kernel doesn't seem to mind.

Thank you
