Instructions for Adding HDDs to RAID

[wenuam]

Do you have more slots available, please?

Nope, all 9 slots are now occupied.

Migrating to TRAID+ in TOS6 requires one more disk.

OK, then I guess it's done and it'll stay on TOS 5 and vanilla TRAID.

I have a problem with adding a disk to the TRAID.
Here are all the steps I took reading this post and they seem correct to me:
Starting situation, single disks not in raid:
- I have a NAS F5-221 5 slot
- Slot 1 = SSD 128 Gbyte with TOS v. 5.1.145
- Slot 2 = HD Exos 18 Tb with about 14 Tb of data.

I wanted to add another 3 new exos 18 tb disks by creating a TRAID for the data only and leaving the SSD as a single system disk.
- I insert the 3 new disks in the empty slots and create the TRAID, create the storage pool, and create a volume at maximum space. I therefore find myself with the SSD, the 18 TB disk with the data and the empty 32.xx TRAID.
- Knowing that the disks to be added to the TRAID must be empty and without partitions, first I copy all the data from the disk to the TRAID.
- Once this is done, having made sure that I have duplicated all the data exactly, I delete the single disk and delete the volume.
- I join the now empty disk to the existing TRAID, it takes almost 3 days to finish the job. At this point I only have 2 storage pools, the 128 Gbyte SSD with TOS and the TRAID whose volume however sees it as only 32.xx Tb as it was before adding the disk.
- I go to the volumes item and as per your post, I expand the existing volume to the maximum capacity. However, I have the problem that although the volume seems occupied by the 14 Tb of data that I originally had, I do not see the main data folder, it seems unreachable.

In the network resources of the PC I can see it but I cannot access it:



The folder with the data is the one in the black rectangle, those circled in red are folders that were on another disk that I had removed before all these steps and I don't understand why they are still visible on the network...


In the control panel in TOS I see this:
Storage pool
Volumes
Shared folders
Remote folders



If I remember correctly, my data folder should be in the remote folders... and it's not there!

What should I do?

The known information is not yet available to determine the full extent of the problem.
Regarding the abnormal display of the SMB page, please clear the SMB cache.
Regarding the fact that you cannot see folders containing data, it cannot be ruled out that the problem is caused by a misconfigured storage or a file system error.
We recommend that you contact the customer service window on the official website or support(at)terra-master.com to schedule a remote troubleshooting appointment.

Hi, I correctly added time ago a second disk to the TRAID RAID 1, with FS in BTRFS. The storage poll contains TWO disks and I didn't receive any error apart that the disks from usage statistics seems never going in sleep.

Recently using the LSBLK -f command I discovered that the second disk has 4 partition created through the TRAID configuration, but the first small one contains an OLD BTRFS configuration. (These two disks was in the past part of a RAID 1 BTRFS LINUX configuration)



Is there a way to remove the first partition wrong configuration without corrupting the TRAID (which seems working fine).

Thanks.

What model nas and which version tos? You appear to have edited out a good portion of the screenshot (compared with what I see).
How many drives in total and which are designated 'system disk' as per control panel > Storage manager > disk > disk?

Hi,

I have a TNAS 424 PRO with latest update TOS 6.0.650

These the disks:



In storage pool 2:



As said the two DISKS was part of a RAID1 BTRFS Linux UBUNTU machine. I took one disk from the Linux few months ago and added to the NAS initializing it as TRAID, next I copied files from the remaining disk in the UBUNTU and after, I moved it adding to TRAID configuration. Now I have all disks working in the NAS, but I discovered that the latest disk contains an old signature BTRFS on the first partition SDB1, which I would like to remove due make no sense.

I suspect this may be "normal". Even in a vanilla install of TOS direct onto nvme, the HDD are partitioned as per standard TOS schema, but they are not designated as "active" in the array (whatever it may be). IF the installation process detects an existing os (normally presumed to be TOS) it will not overwrite. {Hence, an update from TOS5 to TOS6 will still have TOS on the HDD}. So, in your case you have sdb1 as btrfs while my "vanila" tos6 has sdb1 as vfat. You can see this directly in the GUI
Control Panel > storage manager > disk > disk
Then expand the individual HDD entry with (down arrow)

and you can compare that with the nvme entries in same dialogue.

We will pay attention to the situation you mentioned and discuss whether there might be any related impacts.

Yes, thanks, for now I leave as is.

I am using TRAID , can I also follow this instruction to add HDDs ?
