Hey folks,
in our production setup with 3 nodes (HCI) we took one host down
(maintenance, stop gluster, poweroff via ssh/ovirt engine). Once it was
up the gluster hat 2k healing entries that went down in a matter on 10
minutes to 2.
Those two give me a headache:
[root@node03:~] # gluster vol heal ssd_storage info
Brick node01:/gluster_bricks/ssd_storage/ssd_storage
<gfid:a121e4fb-0984-4e41-94d7-8f0c4f87f4b6>
<gfid:6f8817dc-3d92-46bf-aa65-a5d23f97490e>
Status: Connected
Number of entries: 2
Brick node02:/gluster_bricks/ssd_storage/ssd_storage
Status: Connected
Number of entries: 0
Brick node03:/gluster_bricks/ssd_storage/ssd_storage
<gfid:a121e4fb-0984-4e41-94d7-8f0c4f87f4b6>
<gfid:6f8817dc-3d92-46bf-aa65-a5d23f97490e>
Status: Connected
Number of entries: 2
No paths, only gfid. We took down node2, so it does not have the file:
[root@node01:~] # md5sum
/gluster_bricks/ssd_storage/ssd_storage/.glusterfs/a1/21/a121e4fb-0984-4e41-94d7-8f0c4f87f4b6

/gluster_bricks/ssd_storage/ssd_storage/.glusterfs/a1/21/a121e4fb-0984-4e41-94d7-8f0c4f87f4b6
The other two files are md5-identical.
These flags are identical, too:
[root@node01:~] # getfattr -d -m . -e hex
/gluster_bricks/ssd_storage/ssd_storage/.glusterfs/a1/21/a121e4fb-0984-4e41-94d7-8f0c4f87f4b6

Now, I dont dare simply proceeding withouth some advice.
Anyone got a clue on who to resolve this issue? File #2 is identical to
this one, from a problem point of view.
Have a great weekend!
-Chris.
