I’m searching for a simple way to combine multiple HDDs to plot with MadMax.
This is to let the system run for a couple of weeks until all drives are full and then move them to my farmer
Would you use one of these?
mhddfs (looks easy, not sure if files are split)
mergerfs (looks complex hard to find the right policy)
I am using mergerfs on my farmer, I see no reason why the same couldn’t be used as plotting destination. Or rather, what I would do is use an NVMe (or fast SSD) as destination and setup madmax via plotman archiving to your temporary HDD array. The way this works with madmax+rsync is filling up all the disks mounted in the target directory. Instead of this, what I am actually doing is from the NVMe destination I move (with madmax+plotman archiving) to the farmer machine over 10GBe (ConnectX 3, so cheap on ebay), to a single mergerfs array.
In case you are going with the mergerfs way, this is my fstab record:
/mnt/pp/disk* /mnt/ppfuse fuse.mergerfs defaults,nonempty,allow_other,use_ino,cache.files=off,moveonenospc=true,dropcacheonclose=true,minfreespace=110G,fsname=mergerfs,category.create=mfs 0 0
