Hi,
When I create filesystem I can specify su and sw paramteres which match underlying storage device. So for example, If I have raid 6 volume made of 6 + 2 disks with stripe size of 256k I create xfs with: mkfs.xfs -d su=256k,sw=6 <disk> But what if I will extend original volume by 2 disks. sw will 8. Will be there a performance panelty compared to filesystem created from scratch with correct sw parameter? BR Marcin |
