    Remote snapshots dissapeared

    Hello Freenas Forum. I have a main machine which is backed up via replication (send/receive) to another machine. They are on the same LAN and in my apartment. Both machines are on 11.2. I have configured this as no deletion of stale snapshots, no encryption and no compression. This has...

    FreeNAS 11.2 clean installation. Data Lost

    Hi, I'm new to FreeNas. I decided to give FreeNAS a shot after trying samba on ubuntu server that has really slow read/write speed. Unfortunately, after doing a clean installation of FreeNAS version 11.2 and followed a video tutorial on how to create a pool and a share, I found out that all the...

    How to Avoid Accidental Deletion of Dataset with Replication

    I've mentioned this at least once before in another post and either got the feeling nobody else felt like this was an issue or they didn't quite appreciate the implication so thought I'll make a specific post about it so you guys can either put my mind at rest or we can conclude this is an issue...

    Data recovery

    Good night people! I made a big mistake in freenas. I had created a storage system with two 1TB HDDs in stripe mode and everything was working perfectly. Later, on a certain day I added manually through the web / graphical interface 1 HD of 500GB and then another of 1TB. Freenas showed error...

    No data in dataset after trying 9.3

    Hi! I'm having some troubles since yesterday because i had issues with AD connect, so i decided to roll back from 11.1 to 9.3. Sadly it seems that the wizard from 9.3 destroyed my dataset. Not that it's gone, but it is simply empty. The odd thing about this is, that even though my dataset...

    Attempted to remove SLOG from Web-UI, possibly nuked pool

    I am running RaidZ-2 on 8 encrypted and non-deduplicated drives, and 1 SSD used as a SLOG. I attempted to remove this SSD for use in as a L2ARC and utilized the Web-UI to do so. I went ahead and removed only the SSD via the "Pool Status" page and all seemed to go ahead well. I attempted to...

    Is this pool failure mode (following a temporary resolved issue without disk damage) possible?

    There's a thread a while back, which asks about what happens if something temporarily renders multiple HDDs in a pool, unavailable (but undamaged). Examples might be, a non-redundant HBA/backplane failure, some kind of federated or linked enclosures/pods/backends get their cable pulled, some...

    Upgrading from 9.3 stable to current version 11

    I am currently running version 9.3 and I am considering upgrading (is it an upgrade?) to version 11 (whatever is the current). Questions: 1) In doing the upgrade, am I placing my pool at risk? I would certainly be devastated at losing 40+TB of data that is currently resident on the server. 2)...
