it seems that this exactly was the problem
Thank you so much!

Hello
We have a problem with hosted engine storage after updating one host
which serves as a gluster server for the engine (the setup is gluster
replica 3 with local disks from 3 hypervisors)

On all the gluster servers
I notice that the affected directories have date in 1970.

I think this has something to do with a gluster bug.
Is there a way to correct this and heal the volume?
Thank you!

For the meta files - check on the bricks which is newest. Usually only the
timestamp inside is different.
If data is the same -> rsync the newest file from the brick to the other bricks and
use 'gluster volume heal <volname> full' (for me it never worked without 'full').
We are expecting fix for the meta files with different gfid very soon.
For the timestamp - write an e-mail to the gluster-users mail list, as they can
help better.
