new drive but no space increase - Enquiries - 09-12-2024
Hey guys, I have a Synology DS918. I replaced a 10TB drive with an 18TB drive using the instructions on your site. I ran the Degraded process and let it run over night. Everything looked to go well. The drive shows on my DiscStation and shows as healthy. I now see 16.4 (the new one), 9.1, and two 18.2 drives. I replaced two 10TB drives with 20TB drives using this process before (the two 18.2s) with no issues. My system is still only showing 34.9TB though. I am not seeing the increase in space though. I restarted the Synology, but its still showing me 34.9TB. The new drive is a ST18000NT001-3NF101. Did I miss something? Always appreciate your help, thanks!

It looks like you’ve done most of the steps right, but there’s a bit more to get the extra space. Since you've replaced one of the 10TB drives with an 18TB, you’ll need to replace the second 10TB drive as well to fully utilize the new capacity.
Once you’ve swapped out the second drive, you’ll need to go into the volume settings on your Synology. After the new drive is recognized and the RAID rebuilds, head over to Storage Manager > Volume and manually increase the volume size to take advantage of the additional space.
