Hi list,

yesterday I noted the following lines into the glustershd.log log file:

[2017-06-28 11:53:05.000890] W [MSGID: 108034]

Digging into the mailing list archive I've found another user with a
similar issue (the thread was '[Gluster-users] glustershd: unable to get
index-dir on myvolume-client-0'), the solution suggested was to verify
if the  /<path-to-backend-brick>/.glusterfs/indices directory contains
all these sub directories: 'dirty', 'entry-changes' and 'xattrop' and if
some of them does not exists simply create it with mkdir.

In my case the 'entry-changes' directory is not present on all the
bricks and on all the servers:

/data/glusterfs/brick1a/hosted-engine/.glusterfs/indices/:
total 0
drw------- 2 root root 55 Jun 28 15:02 dirty
drw------- 2 root root 57 Jun 28 15:02 xattrop

/data/glusterfs/brick1b/iso-images-repo/.glusterfs/indices/:
total 0
drw------- 2 root root 55 May 29 14:04 dirty
drw------- 2 root root 57 May 29 14:04 xattrop

/data/glusterfs/brick2/vm-images-repo/.glusterfs/indices/:
total 0
drw------- 2 root root 112 Jun 28 15:02 dirty
drw------- 2 root root  66 Jun 28 15:02 xattrop

/data/glusterfs/brick3/vm-images-repo/.glusterfs/indices/:
total 0
drw------- 2 root root 64 Jun 28 15:02 dirty
drw------- 2 root root 66 Jun 28 15:02 xattrop

/data/glusterfs/brick4/vm-images-repo/.glusterfs/indices/:
total 0
drw------- 2 root root 112 Jun 28 15:02 dirty
drw------- 2 root root  66 Jun 28 15:02 xattrop

I've recently upgraded gluster from 3.7.16 to 3.8.12 with the rolling
upgrade procedure and I haven't noted this issue prior of the update, on
another system upgraded with the same procedure I haven't encountered
this problem.

Currently all VM images appear to be OK but prior to create the
'entry-changes' I would like to ask if this is still the correct
procedure to fix this issue and if this problem could have affected the
heal operations occurred meanwhile.

Thanks.
