@sjw @roboneko @SuperSnekFriend Okay this is taking longer than expected because my original idea didn't work.

Once I get all the files copied off the block I can delete all the snapshots/data and then copy the database back on to the drives. I should probably run a trim before copying the data back on tho.

@sjw @roboneko @SuperSnekFriend I'm copying a terabyte of data and I'm limited to the write speed of my HDDs in raidz. Luckily zstd plus a record size of 1M means I can write this data at around 300 MB/s. Copying back should be blazing fast since reading highly compressed data linearly plus read performance is way higher. I might actually be limited by the write speed of my nvme striped mirrors.

@sjw @roboneko @SuperSnekFriend 85% done copying to the HDDs

@sjw @roboneko @SuperSnekFriend So looks like copying from the HDDs is super slow for some reason. I'll investigate that later but for right now it looks like everything is about 45% done copying. Once it's complete everything should start back up no problem.

@sjw @roboneko @SuperSnekFriend Oh yeah. Turning on prefetch sped up the transfer by 3x
