Storage pool limit to 39 TB?

[ibuyufo]

Hi All,

 

I recently installed Xpenology using Jun's 1.03b loader with DSM 6.2.2-24922 in a Dell Poweredge R720xd with 12 hard drives which is approximately 40-43 TB of usable space.  The controller in the server is a Dell H310 mini mono that has been converted to IT mode.  I installed DSM into this server and things were working well until I removed a 5TB hard drive and added a 10TB hard drive.  I can't expand the storage pool and when I go into Volume/Configure, I see that I have a Max. allocatable size (GB): 39072.  Do I need to modify DSM 6.2 in order to further expand storage space or is this the limit?  Thanks.

Is this your current configuration: https://www.synology.com/en-global/support/RAID_calculator?hdds=4 TB|4 TB|4 TB|4 TB|4 TB|4 TB|4 TB|4 TB|4 TB|4 TB|4 TB|10 TB

My current configuration is as follow:

 

Drive 1 = 4TB

Drive 2 = 10TB

Drive 3 = 5TB

Drive 4 = 4TB

Drive 5 = 2TB

Drive 6 = 4TB

Drive 7 = 4TB

Drive 8 = 4TB

Drive 9 = 5TB

Drive 10 = 2TB

Drive 11 = 4TB

Drive 12 = 4TB

The raid type is shr? Seems that you need to remove hdd from the raid in the Storage manager and then add the new one.

Yes, the raid is SHR.  Currently the storage pool is about 98% full.  Will that affect the data if I were to remove hard drive(s) from the storage manager such as the 2TB drive?

[Olegin]

Before removing the hdd, transfer some data to the another storage.  2tb is more than 5% in your raid.

I guess the question is why am I limited to only 39TB?

Maybe the 5tb drives are the problem. Can you check in the storage manager if the size of each hdd shows correctly?
