Description customercare 2017-12-26 12:34:03 UTC

Description of problem:

Executing this:

[root@s113 ~]# gluster volume add-brick gv0 replica 3 externalserver:/data/brick1/gv0
volume add-brick: failed: Pre Validation failed on externalserver. Please check log file for details.

on an already working 2 server replica volume gv0,
tells you to look inside the logfile:

[2017-12-26 12:25:25.089637] I [MSGID: 106578] [glusterd-brick-ops.c:499:__glusterd_handle_add_brick] 0-management: replica-count is 3

[2017-12-26 12:25:25.138664] E [MSGID: 106122] [glusterd-mgmt.c:1045:glusterd_mgmt_v3_pre_validate] 0-management: Pre Validation failed on peers
[2017-12-26 12:25:25.138693] E [MSGID: 106122] [glusterd-mgmt.c:2136:glusterd_mgmt_v3_initiate_all_phases] 0-management: Pre Validation Failed

(externalserver is just an alias for this bugreport / peer probe with the real name worked )

Which also says to look into the logfile (above).


Would be nice if some"one" could add an error message, that tells the user, what in the Pre Validation check did not work :)

Which btw, would interesst me very much atm...

Comment 1 customercare 2017-12-26 12:53:44 UTC

the reference to "check log file" is ambiguous in this case,

it was meant to say "check the log file of the failing node",
because that gave out an error, which is not usefull ( again ),
but at least gives a hint to the problem.

In this case: 

[glusterd-utils.c:1166:glusterd_brickinfo_new_from_brick] 0-management: Failed to convert hostname externalserver to uuid

No idea, how this can fail, but it did.

Comment 2 Shyamsundar 2018-06-20 18:28:19 UTC

As a result this bug is being closed.

If the bug persists on a maintained version of gluster or against the mainline
gluster repository, request that it be reopened and the Version field be marked
appropriately.
