| Description | This field specifies Whether snap-reserve should be adjusted automatically when shrinking a volume.
Default value is true.
Example 1: If volume size is 1500MB, snap-reserve is 100%(1500MB) and snap-reserve used
is 100%(1500MB), when shrinking volume to 750MB, snap-reserve will be automatically adjusted to 200%(1500MB)
so that none of the snapshots will be lost.
Example 2: If volume size is 1500MB, snap-reserve is 200%(3000MB) and snap-reserve used
is 50%(750MB), when shrinking volume to 750MB, snap-reserve will be left at 200%(1500MB) even if
auto adjust is set to true because the reserve 200%(1500MB) is greater than snap reserve used 750MB. |
