Hello all,

I currently have my primary NAS running TrueNAS Scale, and I am adding a second as an off-site backup of my critical data which will also run TrueNAS Scale. I have three datastores at the moment, nextcloud, backups, and media. I want to replicate the entirety of nextcloud and backups, but for media I only want to backup my irreplaceable media. This would be personal photos and videos, but not my collection of Linux isos.

Is it possible to have a ZFS Replication task that excludes certain directories? If not, how would you recommend I approach this?

Thanks!

My ISP uses cgnat for ips. Hence, I was unable to connect to my apps from external network. I came to know about ipv6 not being affected by this issue. So, I tried using ipv6 but I was only able to access the ui but no apps. There are open issues on official forum but it is not known when they will be resolved. Can someone suggest another way to approach this problem?

I just finished the process of adding 8 new Seagate Exos 20TB drives to my TrueNAS core system. This question has been asked a lot and it's known seagate drives are loader then most durring operation. Though i could not find anything related to a consistent "shudder" through all my new Exos drives. I have attached a audio clip in the link below. Have any of you come across this specific sound before.

The drives are in a Fractal Design 7 XL case with rubber bumpers in all trays. The case hold 9 WD Red's 12TB, and 8 Segate Exos 20TB. All 17 drives are connected to a SAS 9305-24i in IT mode. Running TrueNAS Core 13.0-U5.3

Hi, I have two Dell T110 ii. One, with more ram and slightly faster CPU acts as main server. I have it running as NFS server, one VM with a couple of services and two apps (nextcloud and immich). Happy with the setup but worried about hardware of main server failing given age. So I have replication set up (pulls from slave to main). The dataset structure is the same. Is it a matter of installing the same apps and VM on slave, load the config of main onto slave and then just leave it to replication to keep the two machines cloned? I switch on slave only on Sundays to allow replication activity. It is some form of backup I guess, although not perfect.

Hey guys! I got my home lab setup going nicely now. One mirror vdev ZFS for my Nextcloud, granting very good performance! Small question though: I got two extra drives now and was thinking if it is worth it adding it already as extra mirror vdev. My question is the following:

Will resilvering of a single disk be quicker if I have my data striped over two mirror vdev than if all my data is in a single mirror vdev?

In other words, I was wondering in that sense if it is safer to replace a disk due to shorter resilver?

Hi, I can't connect to my TrueNAS scale server anymore, not even through the webGUI due to me being stupid. It seems like I need to do a full reinstall and I'm very paranoid about losing data. What do I need to do so I can reinstall truenas without using data? Do I need to export my pools? I don't want to save my config, since it seems to be totally broken. Thanks in advance.

Hey all, not a lot of activity here yet, but hopefully someone can offer some advice!

I'm having major regrets following migration from Core to Scale. The migration via update file went smoothly, but immediately apparent on starting up Scale, all of my SMB shares were broken. Both Linux and Windows clients are unable to connect.

I have since tried creating new users/groups (I noticed that my normal user and group with id's 1000 had been changed to 1001 in Scale), stripping ACL's and recreating, and deleting the shares and recreating. Failure to connect on each attempt.

Is there something I'm missing relating to the migration that prevents SMB from working? I'm not well versed in the inner working, or shell command available for troubleshooting, so most of this has been attempted through the GUI.

Also, I realise I have shot myself in the foot. Like an idiot, I saw the feature flag update message when Scale first started. I clicked through and upgraded without even thinking. I realised what I had done when I restored my Core VM from the previous day - the pool was offline, with zpool import showing an unsupported feature message. So any path back to Core is off the cards I think.

Any help is appreciated...

EDIT:

I think I have found the culprit. I downloaded the debug info and had a look at the SMB config (specifically net_config.txt). For some bizarre reason, the SMB interface had bound to an old IP address (two or three home network revisions ago - not used in many years).

[GLOBAL]

interfaces = 127.0.0.1 192.168.0.200

By selecting the systems current IP address in the optional "Bind IP Addresses" field in the global SMB service settings (under advanced), I've been able to rebind it to the correct address, and I have access (tested in Linux only so far)! phew...

Should I bother to keep using it or shall I just bite the pill and move to SCALE? I have 3 jails and I’m seriously considering my TrueNAS instance as a storage only, and resort to VM and containers on a dedicated machine to use applications.
