[Gluster-users] Possible stale .glusterfs/indices/xattrop file?
Hi Ravi, Thanks for your hints. Below you will find the answer to your questions. First I tried to start the healing process by running: gluster volume heal myvolume and then as you suggested watch the output of the glustershd.log file but nothing appeared in that log file after running the above command. I checked the files which need to be healing using the "heal <volume> info" command and it still shows that very same GFID on node2 to be healed. So nothing changed here. The file /data/myvolume/brick/.glusterfs/indices/xattrop/29e0d13e-1217-41cc-9bda-1fbbf781c397 is only on node2 and not on my nod1 nor on my arbiternode. This file seems to be a regular file and not a symlink. Here is the output of the stat command on it from my node2: File: ?/data/myvolume/brick/.glusterfs/indices/xattrop/29e0d13e-1217-41cc-9bda-1fbbf781c397?

Try the find command again. I see that the inode number is 2798404, not the one you shared in your first mail. Once you find the path to the file, do a stat of the file from mount. This should create the entry in the other 2 bricks and do the heal. But FWIW, this seems to be a zero byte file.

[Gluster-users] Possible stale .glusterfs/indices/xattrop file?
I did a find on this inode number and I could find the file but only on node1 (nothing on node2 and the new arbiternode). Here is an ls -lai of the file itself on node1: -rw-r--r-- 1 www-data www-data 32 Jun 19 17:42 fileKey As you can see it is a 32 bytes file and as you suggested I ran a "stat" on this very same file through a glusterfs mount (using fuse) but unfortunately nothing happened. The GFID is still being displayed to be healed. Just in case here is the output of the stat: File: ?fileKey?
