Issue

AWS disk failed on single node cluster

Fri Dec 08 08:02:25 +0800 [Cluster01: config_thread: sk.panic:alert]: Panic String: aggr aggr1: raid volfsm, fatal disk error in RAID group with no parity disk..  Raid type - raid0 Group name plex0/rg0 state NORMAL. 1 disk failed in the group. Disk 0b.11 S/N [0000000007C65fh8/lNP] UID [0000000007C65fh8/lNP] error: aborted error disk event. in SK process config_thread on release 9.12.1P3 (C)

Cause

An intermittent network error between the EC2 instance and EBS storage

Solution

  1. Use ASUPs to figure out which disk failed
  2. Use the AWS vol name to search for the disk in the AWS console
  3. If the disk is healthy, reattach the disk to the virtual machine
  4. If the disk is not healthy a new disk will need to be created and added to the virtual machine
Note: If the disk is not healthy and needs to be replaced, there is no way to recover the data for that aggregate unless there is a backup of that data available
