Issue

  • THICK provisioned LUN goes offline due to insufficient space in the volume.
  • EMS Log:

Mon Nov 30 00:10:19 CET [NETAPP: wafl_exempt00: wafl.vol.full:notice]: Insufficient space on volume NetApp_VOL@vserver:3bd37812-3d30-11ea-a58e-d039ea12b1e4 to perform operation. 4.00KB was requested but only 1.00KB was available.
 

  • Check if the LUN is THICK Provisioned:

::> lun show /vol/NetApp_VOL/lun_NetApp_VOL -fields space-reserve
vserver path                            space-reserve
------- ------------------------------- -------------
svm1    /vol/NetApp_VOL/lun_NetApp_VOL  enabled

  • Check available space in the volume:

::> df -h NetApp_VOL
Filesystem              kbytes       used          avail capacity  Mounted on
/vol/NetApp_VOL/        8332236556   8332236556    0     100%      /vol/NetApp_VOL/

  • Check if volume/storage efficiency is enabled and running:

::> vol efficiency show NetApp_VOL
