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 ?
