Hi,
"gluster v heal" command does not heal corrupt files detected by bitrot feature.
You have modified a file from back end and corrupted it.
I think to correct your corrupted files (in fact the part of file in case of disperse volume) you have to delete that part and run gluster v heal <volname> full
to correct the file.
Keeping Kotresh in cc for better input of bitrot.

Subject: [Gluster-users] bitrot error correction in gluster 3.8 distributed dispersed setup
Hi all,
I'm testing the bitrot feature on a distributed dispersed setup: 3 x (8
+ 4).
I simulated a bit-flip on the part of a couple of files in a brick,
having bitrot feature enabled before. The output from ''gluster volume
bitrot vol_1 scrub status'' shows that two files are corrupted as shown
below:
---
Volume name : vol_1
State of scrub: Active
Scrub impact: normal
Scrub frequency: daily
Bitrot error log location: /var/log/glusterfs/bitd.log
Scrubber error log location: /var/log/glusterfs/scrub.log

I have executed ''gluster volume heal vol_1 full'' but it does not seem
to fix the files, however the file that the client reads is the correct
one.
How should I handle this kind of corruption within gluster?
Thanks!
Iñaki.
