  • FlexCache
  • FlexVolume

Issue

  • FlexCache origin volumes randomly fail snapshot creation.  Volumes that utilize the remote access layer include FlexGroup volumes and volumes related to FlexCache. 
  • To determine if remote access layer scrubber is timing out, check the following counter (nonzero values indicate timeouts have occurred):
::> set adv
::*> statistics show -object waflremote -instance 0 -counter scrub_for_snapshot_timeout|scrub_need_snapshot_timeout|scrub_need_freespace_timeout -raw
 
EXAMPLE:
 
cluster::*> statistics show -object waflremote -instance 0 -counter scrub_for_snapshot_timeout|scrub_need_snapshot_timeout|scrub_need_freespace_timeout -raw
Object: waflremote
Instance: 0
