defrag and dupremove

[guni77]

I was just playing around a bit and was very confused about the output of show-shared-extents. Does btrfs defrag -czlib or btrfs defrag change the encoding on the file. Volume ist mounted with compress=zlib. Why is the output of show-shared-extents so different. Maybe it is because I did not fully understand the output and therefore cant interprete it well enough.

[guni77]

is that because the order of the processed files changed?

[guni77]

or is the defrag processing so slow and i shoud have waited a little longer or use btrfs fi defrag -f (flush)

[guni77]

I think this thread can be removed. I noticed a few things. I cant see in the fe_flag for shure which compression algorithm is used, I am not shure if "defrag" and defrag -czlib does something different, I guess it does. Maybe it depends on mount options. I noticed that even with compress-force=zlib while defrag -czlib some blocks look like there are not compressed. So I switched to lzo giving me better performance and looks clearer what it does for me. What also made me puzzle that extent size for some of my files where very different with zlib. But anyway I am no expert with this stuff, just playing arround.

[guni77]

seem like with btrfs-progs v4.1.2 in case files are packed with zlib and you run btrfs fi defrag -clzo, you need to run defrag two times do make all extents same size (524288) except the last of course. defrag fi defrag, in my opinion stores the extents unpacked, in contradiction what the documentation says. Maybe you can note as a feature if technical feasible, that show-shared-extents show the state of the extent like uncompressed,zlib,lzo eg. I think this is where i got confused

[guni77]

even not shure if it matters if fe_length is not the same for all extents, intuition tells me it is.

[guni77]

anyway thanks for the great work
