[Gluster-users] gfid entries in volume heal info that do not heal

Tue Oct 24 07:05:06 UTC 2017

Hi Jim,

Can you check whether the same hardlinks are present on both the bricks &
both of them have the link count 2?
If the link count is 2 then "find <brickpath> -samefile
<brickpath/.glusterfs/<first two bits of gfid>/<next 2 bits of gfid>/<full
gfid>"
should give you the file path.

Regards,
Karthik

I have not yet tracked down physical location of these files, any tips to finding them would be appreciated, but I’m definitely just wanting them gone.  I forgot to mention earlier that the cluster is running 3.12 and was upgraded from 3.10; these files were likely stuck like this when it was on 3.10.
