Please do share your findings. I suspect my own RAID+LVM+EXT3/4 |
| 5 |
system is not optimized - especially with LVM I have no idea how |
| 6 |
blocks in ext3/4 end up mapping to stripes and physical blocks. Oh, |
| 7 |
and this is on 4k disks. |

Honestly, this is one of the reasons I REALLY want to move to btrfs |
| 10 |
when it fully supports raid5. Right now the various layers don't talk |
| 11 |
to each other and that means a lot of micro-management if you don't |
| 12 |
want a lot of read-write-read cycles (to say nothing of what you can |
| 13 |
buy with a filesystem that can aim to overwrite entire stripes at a |
| 14 |
time). |
