[Gluster-users] Volume heal info not reporting files in split brain and core dumping, after upgrading to 3.7.0

[Alessandro De Salvo]

Hi Pranith,
many thanks for the help!
The volume info of the problematic volume is the following:

# gluster volume info adsnet-vm-01
 
Volume Name: adsnet-vm-01
Type: Replicate
Volume ID: f8f615df-3dde-4ea6-9bdb-29a1706e864c
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: gwads02.sta.adsnet.it:/gluster/vm01/data
Brick2: gwads03.sta.adsnet.it:/gluster/vm01/data
Options Reconfigured:
nfs.disable: true
features.barrier: disable
features.file-snapshot: on
server.allow-insecure: on

The log is in attachment.
I just wanted to add that the heal info command works fine on other volumes hosted by the same machines, so it’s just this volume which is causing problems.
Thanks,

	Alessandro

The heal was launched correctly, but when I now perform an heal info there is no output, while the heal statistics says there are actually 2 files in split brain. In the logs I see something like this:
