Description Anil Shah 2015-08-19 06:48:45 UTC

Description of problem:

when running gstatus command with -b argument, it gives error.

Version-Release number of selected component (if applicable):

[root@knightandday ~]# rpm -qa | grep glusterfs
glusterfs-api-3.7.1-11.el7rhgs.x86_64
glusterfs-cli-3.7.1-11.el7rhgs.x86_64
glusterfs-libs-3.7.1-11.el7rhgs.x86_64
glusterfs-client-xlators-3.7.1-11.el7rhgs.x86_64
glusterfs-server-3.7.1-11.el7rhgs.x86_64
glusterfs-rdma-3.7.1-11.el7rhgs.x86_64
glusterfs-3.7.1-11.el7rhgs.x86_64
glusterfs-fuse-3.7.1-11.el7rhgs.x86_64
glusterfs-geo-replication-3.7.1-11.el7rhgs.x86_64

[root@knightandday ~]# gstatus --version
gstatus 0.64


How reproducible:

100%

Steps to Reproduce:
1. Create 6*2 distribute replicate volume
2. Mount volume as FUSE/NFS mount on clients
3. check gstatus -b 

Actual results:

[root@knightandday ~]# gstatus -b
 
[root@darkbeauty ~]# gstatus -b
 
updateSelfHeal.Unable to apply self heal stats due to knightandday:/rhs/brick1/b1 not matching existing brick objects, and can not continue.


Expected results:

Command should succeed without error and give self-heal state

Comment 3 Sachidananda Urs 2015-08-28 05:33:05 UTC

This was due to a stray Try, Except block.

After the fix:
