Of course. Here's the full log. Please, note that in FUSE mode
everything works apparently without problems. I've installed 4 vm and
updated them without problems.

I think this is the second situation because that message appears only

...on problem is still there (but without errors in bricks' log file).
What does the "link" error in bricks log files means ?
I've seen the source code looking for the lines where it happens and it
seems a warning (it doesn't imply a failure).

Problem with Gluster 3.12.4, VM and sharding
..., I configure KVM to access VM images via a FUSE mount,
everything seems to work correctly.
Note that the problem with install is verified 100% time with QCOW2
image, while it appears only after with RAW disk images.
Is there anyone who experienced the same problem ?
Thank you,

...gluster1/Test/Test-vda.img 20G
et voila !
No errors at all, neither in bricks' log file (the "link failed" message
disappeared), neither in VM (no corruption and installed succesfully).
I'll do another test with a fully preallocated raw image.
