Disks/aggregates

  • aggr status - get the status of agregated
  • aggr status -r aggr-name - get the raid layout of aggregate aggr-name
  • aggr show space -g aggr-name - show space in GB of aggr-name
  • sysconfig -r - show physical disks and their membership in aggregates
  • vol status - list volumes and thair status
  • vol status volname -v - get detailed volume status

To check volume autogrow options:

  1. priv set diag
  2. printflag

Check the wafl_reclaim_theshold flags. There's 5 (_t, _s, _m, _l & _xl) representing tiny, small, medium, large and extra large volumes. The values are in hex, so for tiny it's 0x55 (85%) by default meaning the volume will grow when it's 85% full and 0x62 (98%) for xl volumes. For guidance, ting volumes are less than 20GB, XL are greater than 1TB. Values can be changed using the setflag command.

Shares/exports

  • cifs shares - list CIFS shares
  • exportfs - list NFS exports

To find out which servers are using a NFS export:

  1. options nfs.per_client_stats.enable on
  2. vfiler run vfiler0 nfsstat -l

(Disable option after use)

  • snap sched vol-name - show the snapshot schedule for volume volname
  • snap list - list all snapshots
  • snap recliamable vol-name snapshot-name - list the space that would be freed by deleting the snapshot
  • snap autodelete vol-name target_free_space 10 - trigger an autodelete of volname snapshots when free space is 10% or less
