WebUI: resize VOL but LUN says vol hasn't changed

[fajarpri2]

Hi all,

N3600 Ontap 7.3.3

I make vol1 bigger to 900GB, but when I try to make a LUN in it bigger, it says the vol1 is full.

From WebUI:

Name:		vol1
Type:		Flexible		Root Volume?		-
FlexClone ?		-		Containing Aggregate:		aggr0
Status:		online,raid_dp
Used Capacity:		900 GB		Space Guarantee		volume
% Used:		100%		Language:		en_US
Total Capacity:		900 GB		Total Size:		900 GB
Number of Files:		116		Max Directory Size:		17.9 MB
Max Files:		28 m
SNAP Mirror?		-		SNAP Directory?
SNAP?		-		Resync SNAP Time:		60
SVO Enable?		-		SVO Checksum?		-
Allow SVO RMAN?		-		SVO Reject Errors?		-
Create Unicode?				Convert Unicode?		-
Minimal Read Ahead?		-		NV Fail?		-
Fractional Reserve :		100		Extent?		-
FS Size Fixed?		-		Update Access time?
I2P?				Ignore Inconsistent??		-

From CLI:

n3600a> df -h
Filesystem               total       used      avail capacity  Mounted on
/vol/vol0/               537GB      745MB      536GB       0%  /vol/vol0/
/vol/vol0/.snapshot      134GB      197MB      134GB       0%  /vol/vol0/.snapshot
/vol/vol1/               900GB      900GB        0KB     100%  /vol/vol1/
/vol/vol1/.snapshot        0KB     9645MB        0KB     ---%  /vol/vol1/.snapshot
/vol/vol2/               100GB      100GB        0KB     100%  /vol/vol2/
/vol/vol2/.snapshot        0KB     1742MB        0KB     ---%  /vol/vol2/.snapshot

n3600a> lun show
    /vol/vol1/qtit/lun0          100g (107374182400)  (r/w, online, mapped)
    /vol/vol1/qtqatmsoshare/lun0  450.1g (483247783936)  (r/w, online, mapped)
    /vol/vol2/qtdevtmsoshare/lun0   94.8g (101795758080)  (r/w, online, mapped)

Should I try to resize the LUN from CLI?

Why the WebUI behaves like that?

Thank you

Wow strange....

Out of curiousity, I deleted some snapshots in vol1, and now it shows the free space:

Name	Status	Root	Containing	FlexClone	Avail	Used	Total	Files	Max Files
				Aggregate
	vol0	online,raid_dp		aggr0	-	537 GB	0%	537 GB	7.24 k	20.9 m
	vol1	online,raid_dp		aggr0	-	349 GB	61%	900 GB	116	28 m
	vol2	online,raid_dp		aggr0	-	0 B	100%	100 GB	108	3.11 m

What happens?

Has anyone encoutered this?

Should we abandon the WebUI?

From what I can tell, this is not a problem with WebUI.  But yes, abandon it.

The df command showed you /.snapshot was eating up space.

In this situation you have 2 choices.

1. Delete snapshots (command: snap delete)

2. Grow the snapshot reserve AND the volume (command "snap reserve" and "vol size")

edit: you may want to check snap schedule for this volume.  If you do not want snapshots then do not create them.  If you do, then you should configure the volume with the appropriate snapshot reserve, plus some space guarantee for your LUN, etc.
