we are a little bit in trouble with a dmapi enabled filesystem due to log recovery failed. What happend was a relocation of a half of a three site cluster.
The config seems to be two nodes as quorum node and one as quorum buster node wit the desc only config. what happend after the restart of the relocated node A we had diskdown situation on failure group 2 through a uncoordinated maintenance on these controller. The second problem after the relocation was finished we had problems with a spanning tree problem in the cluster network.
MC Murphy is great;-).
So now we had after mmchdisk gpfst02 start -d "NSD_A;NSD_B; NSD_DESC" an error like to many disk are unavailable. Here comes the question we see log recovery failed1 Why? We had the descriptor disk available and all disk on one site of two failuregroups. is there a way to force the log recovery? Or must we wait to bring the failing disks already up and do then a start cmd.
We are level 22.214.171.124. Linux RHEL6.2
The error itself looks like
Recovery Log IO failed, Unmounting filesystem gpfst02
Too many disks are unavailable
return code 218 reason 225
Log recovery failed.
