Convert a 3Gb drive almost full without a reflink copy #75

Closed servimo closed 5 months ago

As says the title, is this possible? I think I have enough disk space, 624GiB, I will try.

maharmstone commented 5 months ago

Try it. If it can't continue because it runs out of space, it shouldn't corrupt your existing filesystem.

There's no option to suppress the reflink copy, but unless you have a lot of compressed files the overhead should only be a few megabytes.

Thank you for your response, I am in the middle of the calc of the checksums.

What do mean this message in dmesg: "BTRFS warning (device sde1): devid 1 physical 0 len 134217728 inside the reserved space"? it popup everytime I mounted it.

maharmstone commented 5 months ago

It means it's using the first megabyte of the disk, which Btrfs normally keeps free. Is it working despite that warning?

servimo commented 5 months ago

Yes, it's working. How to get rid of this message?
