volume
Enablesthinprovisioningonthevolume.Thinprovisioning
allocatesspacebasedonhowmuchisactuallyused,butgives
theimpressiontheentirevolumesizeisavailable.For
example,a100GBvolumecanbethinprovisionedsoonly
20GBisphysicallyallocated;theremaining80GBbecomes
Unreserved spacestillavailabletothestoragepool.
Additionalspacecanbeallocatedtothevolumeasnecessary.

Specifieshowmuchadditionalspaceshouldbereservedto
storesnapshotsofthisvolume.Thedefaultsettingis100%of
themaximumvolumesize.At100%,a20GBvolumewould
consume40GBofstoragespace:20GBforstorageand20GB
forsnapshots.

• Yellow=In-usewarninglimit.Generatesawarning
messagewhenthespecifiedpercentageoftheminimum
volumereserveisconsumed.Forexample,ifthemininum
volumereserveis20GBandthewarninglimitis80%,the
warningmessagewilloccurwhen16GBisconsumed(or
freespacefallsbelow4GB).
• Red=Maximumin-usespace.Themaximumamountof
spacethatcanbeallocatedonthevolume.Thisamountis
100%bydefault(theentirevolumesize)butcanbe
