Issue

  • When performing a headswap via aggregate relocation, after running the disk reassign command at maintenance mode, running aggr status -r shows the following output:
 
*> aggr status -r
Jan 06 20:18:23 [cluster1-1:fmmb.disk.notAccsble:notice]: All Local mailbox disks are inaccessible.
the system appears to have no disks!
Jan 06 20:18:23 [cluster1-1:raid.assim.tree.noRootVol:error]: No usable root volume was found!
unable to run aggr command
No root aggregate found.
You must specify a root aggregate with
"aggr options root" before rebooting the system.
 
  • When checking the output of a disk show -v command, you can see all root partitions were correctly assigned to the new node system ID:
 
*> disk show -v
Local System ID: 000000003
