Need some help with older Nas which only allow 16TB as largest volume

[apvm]

I have two older NAS, one is Synology 413 and the other is Asustor AS1004T, i upgraded them both with 6TB drives lately and found following difference.
Synology 413 volume size has increased to about 15.66TB but Asustor AS1004T only to about 11.22TB both are 4X6TB HDD with Raid 5 (Synonlogy is SDH).
Wondering what can I do or nothing I could do with AS1004T to its max volume which is also 16TB. Thanks.

First thing I would do is upgrade the OS and see if there's an update that allows for more storage. I find it odd that these NAS devices limit the capacity in the OS vs the drive sizes. Another reason to just DIY a file server instead of off the shelf setups.

Thanks for the reply, they are already on their lastest firmware, I think the only thing I could test it is to buy a 12TB hard drive and move my 10.5TB data from the Asustor to it and then reformat Asustor and see if it will increase the volume size to near 16TB like the Synology which is 15.66TB instead of Asustor 11.5TB, both are with 4x6TB HDD.

reformat

Might be a good idea either way for a backup. There might be something stuck in the mdadm preventing resizing. When you added the 6tb drives were the smaller ones still inside?

I'm monkeyed around with multi drives in my server for ~10 years and just converted to a single 16tb flash drive a year ago as I was sick of lifting it with 5*8tb drives inside. Not to mention the single drive does 6.5GB/s which exceeds the network speed now as well.

I added the 6TB HDD, one by one. Anyway, I just connected an external drive to the AS1004T and backing up a few folders to it and since the external drive is only 8TB, some of the files will go to my computer later, lucky for me is that I have some of the folders backed up on Synology as well, so it should take me about a day to back up the files and I will see if reformat the Asustor will increase my volume to near 16TB instead of just 11.5 TB with four 6TB HDD. Thanks.

One more idea..... Once you put the new drives in maybe do a factory reset if the capacity isn't right still.

Thanks a lot, no need to do a factory reset, after removing the old Raid 5 11.xxTB volume, recreated a new Raid 5 volume and it is now 15.87TB but rebuild seems will take a long time, the volume is building only 8% done but re-synching is only .25 percent and at 10 MB/s only and it will take 6.6 days, is it normal? I hope re-synching will be faster once the volume is built.

Odd but glad it worked out.

Thank you very much for your help, re-synching is now very fast about 80MB/s and will take about 18 hours to finish. Finally everything is almost finish, once it finish re-synching, I will move all files from back up HDD back to NAS. Thanks again.
