Thanks for the hints.
Now I added the arbiter 1 to my replica 2 using the volume add-brick command
and it is now in the healing process in order to copy all the metadata files on
my arbiter node.
On one of my replica nodes in the brick log file for that particular volume I
notice a lot of the following warning message during ongoing healing:
[2017-06-30 14:04:42.050120] W [MSGID: 101088]
[common-utils.c:3894:gf_backtrace_save] 0-myvolume-index: Failed to save the
backtrace.
Does anyone have a idea what this is about? The only hint here is the word
"index" which for me means it has something to do with indexing. But is this
warning normal? anything I can do about it?
Regards,
M.
