Applies to
- ONTAP 9
- Flexgroups
- Logical space reporting
- Logical space enforcement
- Autogrow
Issue
Flexgroup did not trigger autogrow when logical-space used was full.
Example:
--- writes to FlexGroup ---
cluster1::*> vol show fg2* -fields size,physical-used,used,logical-used,percent-used,max-autosize
vserver volume size used percent-used max-autosize physical-used logical-used
------- ------ ------- ------ ------------ ------------ ------------- ------------
svm1 fg2 10.97GB 5.27GB 48% 9.60GB 5.42GB 7.80GB
svm1 fg2__0001 4.21GB 2.62GB 62% 4.80GB 2.68GB 2.63GB
svm1 fg2__0002 6.76GB 2.65GB 39% 4.80GB 2.75GB 5.17GB
3 entries were displayed.
--- cont. writes to FlexGroup ---
--- max-autosize reached and logical-used is greater than max-autosize.
