I guess you're right aboug gfid, I got that:
[2017-07-07 07:35:15.197003] W [MSGID: 108008]
[afr-self-heal-name.c:354:afr_selfheal_name_gfid_mismatch_check]
0-applicatif-replicate-0: GFID mismatch for
<gfid:3fa785b5-4242-4816-a452-97da1a5e45c6>/snooper
b9222041-72dd-43a3-b0ab-4169dbd9a87f on applicatif-client-1 and
60056f98-20f8-4949-a4ae-81cc1a139147 on applicatif-client-0
Can you tell me how can I fix that ?If that helps I don't mind deleting
the whole folder snooper, I have backup.
Thanks.
