NETAPP - How to enable the autosize and autogrow on NetApp.

                      NETAPP - How to enable the autosize and autogrow on NetApp.

With this option the volume will grow with a specified space.
The first thing would be to enable the autosize option on the volume.
That can be achieved by running the following command.

NTPboxer*> vol autosize test
Volume autosize is currently ON for volume 'test'.
The volume is set to grow to a maximum of 1258080 KB, in increments of 52420 KB.

NTPboxer*> priv set diag

NTPboxer*> printflag wafl_reclaim_threshold_t
wafl_reclaim_threshold_t = 0x55

THE COMMAND ABOVE STATES THAT WHEN THE VOLUME REACHED 85% (0X55 - HEX FIGURE) IT WILL AUTOGROW BY CERTAIN FRAGMENTS.

NTPboxer*> df -k test
Filesystem               total       used      avail capacity  Mounted on
/vol/test/            996148KB      188KB   995960KB       0%  /vol/test/
/vol/test/.snapshot    52428KB        0KB    52428KB       0%  /vol/test/.snapshot

With the volume in place i started to dump some data into it to check the autogrow process.

IF YOU SEE ABOVE THE VOLUME GOT AUTOSIZED WHEN IT REACHED 85%.
