How to modify the maxdirsize in ONTAP 9?

Applies to

• ONTAP 9
• Cloud Volumes ONTAP
• Maximum Directory size
• Event management system (EMS) message
  • Max Directory size error - AutoSupport message
  • ENOSPC

Description

When maxdirsize is exceeded in ONTAP, an out of space error (ENOSPC) is issued to the client and an event management system message is triggered. To remediate a directory size issue, a storage administrator must increase the maxdirsize setting or move files out of the directory.

Procedure

It is recommended that you only increase maxdirsize by 2% increments of the current value to reduce a performance impact.

1.   Set advanced privilege

::> set advanced

2. View your current maxdir size. See How to identify the current maxdir-size value for my volume?
3. Calculate the new value as per the formula

(maxdir-size x 2%) + maxdir-size = new value

Example:

4. Increase the maxdirsize using the command:

 volume modify -vserver {NAME} -volume {NAME} -maxdir-size {size}

Example:

Setting a maximum directory size of 327MB for a volume named vol1 on a Storage Virtual Machine (SVM) named svm1.

::> set advanced

::*>  volume modify -vserver svm1 -volume vol1 -maxdir-size 327MB

Volume modify successful on volume: vol1
::*> volume show -volume vol1 -fields maxdir-size
(volume show)
vserver volume maxdir-size
------- ------ -----------
svm1     vol1   327MB

Note: Make sure the value for -maxdir-size includes the "MB" at the end.
