[Gluster-users] Best practices after a peer failure?

[Pranith Kumar. Karampuri]

hi Mohit,
 Self heal happens whenever a lookup happens on an in-consistent file. The commands ls -laR, find do lookup on all the files recursively under the directory we specify.

I thought self healing is possible only after we run "ls -alR or find
.." . It looks self healing is supposed to work when a dead node is
brought up, is that true?

Please also give the output of gluster peer status on both the machines after restart. zip the files under /usr/local/var/log/glusterfs/ and /etc/glusterd on both the machines when this issue happens. This should help us debug the issue.
