[Gluster-users] remove arbiter to add new brick - possible?

[DUCARROZ Birgit]

Hi Xavi,

Thank you a lot for your response. That's the information I needed.

However, I run actually into an other error message:


root at nas22:# gluster volume add-brick vol-cdimages nas28:/bigdisk/brick7 
nas29:/bigdisk/brick8 nas23:/bigdisk/brick9

volume add-brick: failed: Pre Validation failed on nas28. Please check 
log file for details.
Pre Validation failed on nas29. Please check log file for details.


The logfile says:

[2019-12-27 11:37:41.439048] E [MSGID: 106121] 
[glusterd-mgmt.c:1148:glusterd_mgmt_v3_pre_validate] 0-management: Pre 
Validation failed on peers

All peers are in Cluster and Connected.

How can I solve this problem?
Kind regards,
Birgit
