[Gluster-users] Conv distr-repl 2 to repl 3 arb 1 now 2 of 6 arb bricks won't get healed
I can't find anything suspicious in the brick logs other than authetication refused to clients trying to mount a dir that is not existing on the arb_n, because the self-heal isn't working. I tried to add another node and replace-brick a faulty arbiter, however this new arbiter sees the same error. Last idea is to completely remove first subvolume, then re-add as new hoping it will work. A. "a.schwibbe at gmx.net" a.schwibbe at gmx.net ? 31.
