yanjun Posted March 7, 2022 Share #1 Posted March 7, 2022 We all know that Synology's single volume limit has three cases: 16TB, 108TB, and 200TB. I checked the relevant documents carefully, the 3622xs+ I am currently using supports 200TB, provided the memory is greater than 32GB, but when I use 40GB of memory and 10 18TB hard drives to create storage space and storage volumes (RAID5, RAID6, SHR2 have all tried ), the limit is still at 108TB, does anyone know what the problem is.

Tenshou Posted March 7, 2022 Share #2 Posted March 7, 2022 It only works on DSM 6.3 or lower. After that, they only allow 108TB. So you need to make a 200TB volume on the lower DSM version and migrate them to DSM 7.1 Quote Link to comment Share on other sites More sharing options...

I am using RAID6 btrfs. Quote Link to comment Share on other sites More sharing options...

I am using RAID6 btrfs. as 3615/17 are supported too for 200TB, try jun's 1.03b and dsm 6.2.3 if that works try redpill 6.2.4 to create a >108TB volume Quote Link to comment Share on other sites More sharing options...

Tenshou Posted March 13, 2022 Share #9 Posted March 13, 2022 (edited) They do support it. I am running a few volumes greater than 108TB started from DS3617xs and now on DS3622xs. Just make the volumes using Jun’s and then create a new DSM 7 install. Migrate those disks over and you will now have 200TB on your DSM 7 installation Edited March 13, 2022 by Tenshou Quote Link to comment Share on other sites More sharing options...
