hi Mohit,
I have sent a patch for the bug you have raised for self-heal not working in one case already.
For a file, it should have either different extended attributes for client-0/1 (assuming two replica) and same gfid extended attribute.
or different extended attribute for gfid.
example:
pranith @ /mnt/client
07:24:05 :) $ sudo getfattr -d -m "trusted*" /tmp/1/file1
getfattr: Removing leading '/' from absolute path names
# file: tmp/1/file1
trusted.afr.vol-client-0=0sAAAAAAAAAAAAAAAA
trusted.afr.vol-client-1=0sTwAAAgAAAAAAAAAA
trusted.gfid=0s9JoVEu1WQQCykafEGcz74Q==
pranith @ /mnt/client
07:24:34 :) $ sudo getfattr -d -m "trusted*" /tmp/2/file1
getfattr: Removing leading '/' from absolute path names
# file: tmp/2/file1
trusted.afr.vol-client-0=0sAAAAAAAAAAAAAAAA
trusted.afr.vol-client-1=0sAAAAAAAAAAAAAAAA
trusted.gfid=0s9JoVEu1WQQCykafEGcz74Q==
After self-heal completes they become:
pranith @ /mnt/client
07:27:21 :) $ sudo getfattr -d -m "trusted*" /tmp/1/file1
getfattr: Removing leading '/' from absolute path names
# file: tmp/1/file1
trusted.afr.vol-client-0=0sAAAAAAAAAAAAAAAA
trusted.afr.vol-client-1=0sAAAAAAAAAAAAAAAA
trusted.gfid=0s9JoVEu1WQQCykafEGcz74Q==
pranith @ /mnt/client
07:27:26 :) $ sudo getfattr -d -m "trusted*" /tmp/2/file1
getfattr: Removing leading '/' from absolute path names
# file: tmp/2/file1
trusted.afr.vol-client-0=0sAAAAAAAAAAAAAAAA
trusted.afr.vol-client-1=0sAAAAAAAAAAAAAAAA
trusted.gfid=0s9JoVEu1WQQCykafEGcz74Q==
Thanks
Pranith.

Subject: Re: Self heal doesn't seem to work when file is updated
Can somone from gluster developer community please tell respond how to
find if self heal worked?
Or better yet how to determine if a file needs to be healed? Please
let me know as this very important aspect.
