Hello duy.ipad, you can’t shrink a raid 10 DM.  You will need to create a new volume then copy the data to that volume and then destroy the old volume. Please let us know if you have any other questions.
Hi, [IMAGE] - We are using SC4020. - We've run out of SSD tier, so we've changed the profile of volume which size is 10-TB from "Recommend" to our custom. Our custom profile use RAID-6 on both tier SSD and HDD.- The problem is the storage does not shrink the RAID-10-DM allocated space, so all our data is now replicate to HDD tier because of RAID-6 level in SSD tier has not enough free space. - Can we shrink RAID-10-DM allocated space? Thank you very much.
Can we shrink RAID-10-DM allocated disk space?
