The root volume (/mroot) is dangerously low on space.

[ANSHUL_JAISWAL]

I am getting the following error message :

The root volume (/mroot) is dangerously low on space (<10MB). To make space

available, delete old Snapshot copies, delete unneeded files, and/or expand the

root volume's capacity.  After enough space is made available, reboot this

controller.  If needed, contact support personnel for assistance.

I am getting this warning when I am trying to login to the cluster.

I have deleted all snapshots, nosnap is ON for all volumes, also snapautodelete is ON.

I am getting this error after each 2-3 days. I dont understand why the volume is getting full each time.

Now, this time I have no snap shot for any volume, I dont know what to delete to free the volume.

I tried to increase the aggregate size by adding disks to it so that I can increase volume size, but I am unable to do that because failed to add disk to aggregate.

Could anybody let me know the steps to increase the aggregate size and volume size.

Do one of the things it asks you.  For example, delete old snapshot copies:

Enter node level -- node run local

snap list vol0

snap delete -a vol0

Repeat these on all nodes which are complaining, and reboot each one.

In the future, think about snapshot autodelete for vol0, or in a non-production environment simply turn off snapshot schedule for vol0 (snap sched vol0 0 0 0)
