Hello Dziannis,

I am also planning to change our cluster from straw to straw2 because we
habe different hdd sizes and changes in the HDD-Sizes always triggers a lot of 
reorganization load.

Did you experience any issues ? Did you already change the other hosts ?

Don't you think we will have less reorganization if we change the algorithm on
all machines at the same time ?

We are using hammer 0.94.2 and proxmox Distribution with RedHat Kernel 
2.6.32-37-pve

Do you think the kernel can be a problem ?

Thanks
  Christoph
