Description Shwetha K Acharya 2021-09-21 07:22:42 UTC 
This issue is resolved upstream with https://github.com/gluster/glusterfs/issues/1925, but still not part of downstream.

It was observed recently by the customer in BZ2004767.
Analysis details: https://bugzilla.redhat.com/show_bug.cgi?id=2004767#c9

I would like to propose this bug to 3.5.6 considering 
1. critical customer impact.
2. unusability of virtual xattrs from geo-rep.

@Prashant,

  dht_pt_getxattr() which was introduced by a patch (https://github.com/gluster/glusterfs/issues/405) for perf 
  improvements in pass-through mode (i.e. where distribute-count is 1) does not handle virtual xattrs.Later on we
  merged the same in downstream also. For geo-rep there is a virtual getxattr done by geo-rep on the fuse mount 
  via DHT_SUBVOL_STATUS_KEY and it must not be sent over the network. dht_getxattr() handles it but its missing in 
  dht_pt_getxattr(), so the geo-rep session goes faulty.The issue will be observe only while dht subvol count is 1.

  The bug is critical for geo-rep aspect, Can you please give your vote?

Thanks,
Mohit Agrawal
