Hi. Switching from TRAID to RAID1 is not supported. If you have the option to back up your data, you may consider rebuilding the storage pool.

I mean the system volumes where TOS is installed. I understand that it cannot be done without complete re-setup. But could you confirm that raid1 can be defined during clean system install? As I remember, that option was not available if the system is expected to be re-installed to the disks containing previous TOS. I was able to select disks but not to change raid level (from traid to raid1).

The Storage Pool raid level is assigned separately from the operating system install. Since everyone seems to demand that data remains intact, that means the storage pools have to remain intact . Even then, you typically cannot change the raid mechanism after install since the raid mechanism is (for the most part) different for different raid levels. (Parity assignment and all that good stuff).

Yes, agree! I assume that I need to format system disks outside of TNAS to get an option to select raid level for the system pool? Is that correct?
From the other view, the raid for the system disk is not really important because does not contain a sensitive data to loss. The highest price is a time for re-setup the system

You cannot select the raid option for the operating system. This is fixed at raid 1 for 2 disks (TOS 6, not earlier versions) or single disk if only 1 disk is selected. Until the 6.0.688Beta is sorted and the changes incorporated into a production release, this cannot be changed post install. (It would be technically possible as you implied, but not to be recommended. Reformatting would need to clean the old data partitioning as well.)

It is traid for me for two nvme ssd. That is why I am asking. I just want to be sure that in case of 1 disk damage the system will boot in 100%. Previously I got issues with traid/btfs with no physical issues identified with installed hdds. The traid just started restructure in the night amid complete well-being (background kworker process) with failed traid in the morning. USB backup saved my data At the moment I am testing raid1/ext4 for main hdd storage.

PS Raid rebuild was not related with any unusual scenario.

Traid is only applicable to DATA storage. That is STORAGE POOLS (1-n). The applied file system (Ext4, Btrfs, etc) is applicable to VOLUMES on the Storage Pools. These are completely distinct to the underlying Operating System which has it's own, separate partitioning and file system(s).

The operating system (TOS4/5/6) is applied to a portion of the SYSTEM DISKS, which may be be on one or more of the physical drives whether these are nvme, ssd or hdd.
{TOS6 on a fresh install currently has a limit of 2 system drives. If earlier version were updated to 6.0, the multi-disk (>2) variation will still exist}.

The first 3 partitions on a System Drive are organised as
1: 285MB - Boot partition (NOT to be confused with internal USB 'initboot' which serves no direct purpose with respect to the TOS o/s)
2: 8.0 GB (nominal == 7.6GB approx) - TOS o/s
3: 2GB (nominal == 1.9GB approx) - SWAP Partition

Partition 1 may be Ext4 or Vfat (depends on Tos version)
Partition 2 will be RAID1 for 2 or more system drives allocated. (It will NEVER be TRAID under the current versions)
Partition 3 same as (2)

The balance of a System Drive may or may not be allocated to Storage Pool (with or without Volumes depending on user decisions)

I trust that adds more clarity.

Hello,

I have a F5-221, running TOS 6.0.555, MAPL0304V17, when i go to TOS > Control Panel > General Settings > System > Update, and click "Check for updates." i get an error message "Update check failed, Please check your connection an try again". My NAS is connectted to the internet, i can download new apps, update current apps, but i cant update TOS.

Any advices?

Thanks!

I just did the latest update for TOS 6 last night. And today I'm getting bad gateway. Can't access from Desktop App or Web. And it had a fixed IP address before the update. I know very little about Linux. I can see 2 Ip addresses in my router. Those Ip's can be seen in the Desktop app. Web app gives Bad Gateway and PC app times out.

Hello, could you please tell me the specific versions of TOS before and after the upgrade? Do you have a screenshot of any Bad Gateway errors?
