[Gluster-users] glustershd: unable to get index-dir on myvolume-client-0

[mabi]

Thanks Ravi, I now manually created the missing "dirty" directory and do not get any error messages in the gluster self-heal daemon log file.

There is still one warning message which I see often in my brick log file and would be thankful if you could let me know what this means or what the problem could be:

[2017-05-07 11:26:22.465194] W [dict.c:1223:dict_foreach_match] (-->/usr/lib/x86_64-linux-gnu/libglusterfs.so.0(dict_foreach_match+0x65) [0x7f8795902f45] -->/usr/lib/x86_64-linux-gnu/glusterfs/3.8.11/xlator/features/index.so(+0x31d0) [0x7f878d6971d0] -->/usr/lib/x86_64-linux-gnu/libglusterfs.so.0(dict_foreach_match+0xe1) [0x7f8795902fc1] ) 0-dict: dict|match|action is NULL [Invalid argument]

Any ideas?

Hi Ravi,

Thanks for the pointer, you are totally right the "dirty" directory is missing on my node1. Here is the output of a "ls -la" of both nodes:

node1:
drw------- 2 root root 2 Apr 28 22:15 entry-changes
drw------- 2 root root 2 Mar 6 2016 xattrop

node2:
drw------- 2 root root 3 May 2 19:57 dirty
drw------- 2 root root 2 Apr 28 22:15 entry-changes
drw------- 2 root root 3 May 2 19:57 xattrop

Now what would be the procedure in order to add the "dirty" directory on node1? Can I simply do an "mkdir dirty" in the indices directory? or do I need to stop the volume before?

mkdir should work. The folders are created whenever the brick process is started, so I'm wondering how it went missing in the first place.

Hi,
I have a two nodes GlusterFS 3.8.11 replicated volume and just noticed today in the glustershd.log log file a lot of the following warning messages:

Does someone understand what it means and if I should be concerned or not? Could it be related that I use ZFS and not XFS as filesystem?

In replicate volumes, the /<path-to-backend-brick>/.glusterfs/indices directory of bricks must contain these sub folders: 'dirty', 'entry-changes' and 'xattrop'. From the messages, it looks like these are missing from your first brick (myvolume-client-0). Can you check if that is the case?
