Hi,
How does one determine the XFS sunit and swidth sizes for a software
raid10
with 3 copies?
mkfs.xfs uses the GET_ARRAY_INFO ioctl to get the data it needs from
software raid and select an appropriate sunit/swidth...
although i'm not sure i agree entirely with its choice for raid10:
So do I, especially as it makes no checks for the amount of copies (3 in my
case, not 2).
it probably doesn't matter.
This was essentially my question. For an array -pf3 -c1024 I get swidth = 4 *
sunit = 4MiB. Is it about right and does it matter at all?
how many drives?
Sorry. 4 drives, 3 far copies (so any 2 drives can fail), 1M chunk.
