I'm considering reshaping an almost full (99%) 7-disk RAID5 array to a 9-disk RAID6 array, but the fact that mdadm-3.1 (which I understand is the only one capable of doing that) hasn't been released (even in -rc) yet has me a little worried...
Do you have any ETA for a release? Do you consider the code stable enough already? I know I should backup before the reshape, but it's not technically (and financially ;-P) feasible; that's why I use el-cheapo software RAID on el-cheapo consumer grade hardware... :)
Thanks for your hard work
