Hi here,

I open my own thread to explain my issue.

Friday i have seen new version of Freenas - 11.2 STABLE.
I switch to 11.2 STABLE...launch upgrade --- ALL work well and DATA is here.

After reboot...dashboard inform me to upgrade POOL....ok so i launch too upgrade the POOL --- SAME work well and DATA is here.

2 hours later i receive multiple email like :

Code:
Quota exceed on dataset RaidZ/Apps.

Used 83.66% (314.39 GB of 375.81 GB)


Code:
Refquota exceed on dataset RaidZ/Apps.

Used 83.66% (314.39 GB of 375.81 GB)


And 1 hour after receive then email i receive :

Code:
New alerts:

* The boot volume state is UNKNOWN:

* The volume RaidZ state is UNKNOWN:


Alerts:

* The volume RaidZ state is UNKNOWN:


But i have see this just yesterday and try to see what happen.

I'm log to the dashboard and see FreeNAS not work correctly.
I go in the console and see the system :

Code:
ELF interpreter /libexec/ld-elf.so.1 not found


Ok so i decide to reboot...and same thing.
I decide to reboot to last version 11.1 ... work well...but i see no DATA in my RaidZ folder...just one folder contain data (Videos/Archives) bu not all my data to this folder and all another folder is empty.

My system is :
Code:
Asrock RACK E3C226D2I

Do you have snapshots setup on your pool?

The data-sets are still there and contain data, see the USED column. What does zfs mount say?

This is the part that I don't understand. This sequence of events makes little sense to me.

In any case, there is no indication of data loss, so you probably have folders with the same name as the datasets, which got mounted on top of them, hiding them.

Since the OP author upgraded the pool (edit: and now is trying to boot 11.1sth), the below may be in effect...
2.5.1. Caveats
Be aware of these caveats beforeattempting an upgrade to 11.2:
  • Warning: upgrading the ZFS pool can make it impossible to go back to a previous version. For this reason, the update process does not automatically upgrade the ZFS pool, though the Alert system shows when newer feature flags are available for a pool. Unless a new feature flag is needed, it is safe to leave the pool at the current version and uncheck the alert. If the pool is upgraded, it will not be possible to boot into a previous version that does not support the newer feature flags

Can it be ruled out easily?

i5s do not support ECC.


This is the part that I don't understand. This sequence of events makes little sense to me.

In any case, there is no indication of data loss, so you probably have folders with the same name as the datasets, which got mounted on top of them, hiding them.

For i5 i know...i change it soon...my last CPU is G3220 and support ECC...mistake to me but i dont thing the problem is CPU

I dont know how to find hiding....USED dont say my TOTAL size before upgrade....I repeat before upgrade i have 7 To and more data...now i have only 565 Go.... :(

Since the OP author upgraded the pool, the below may be in effect...


Can it be ruled out easily?

Ok but...11.2 RC2 dont support new pool version ?

How i can verify the version on my pool and install FreeBSD maybe to see if my ZFS version and DATA is safe ?

Can you use cd and ls to navigate the mounted folders? ZFS reports "used" space differently in different places.

Just slow down. Your data is probably fine. With ZFS pool version does not matter much, just feature flags in use.

You're down 7 TB? That does sound like a problem. But that would have left your pool pretty full. Were you at 90+% full?

root@freenas:/mnt/RaidZ # cd Apps/
root@freenas:/mnt/RaidZ/Apps # ls
root@freenas:/mnt/RaidZ/Apps # ls -lah
total 48
drwxrwx---+  2 1001  1002      2B Nov 30 19:26 .
drwxr-xr-x  14 root  wheel    14B Dec  2 15:17 ..
root@freenas:/mnt/RaidZ/Apps # du -h
 36K    .

That's always a huge problem, but it shouldn't cause data loss.

So, I have close to no idea what happened here, but it was serious.

I find it very likely that the data is gone, probably deleted by regular filesystem tools and not by ZFS operations. You might want to go through the logs to see if anything interesting pops up, but I don't have much hope for your data.

Sorry to be the bearer of bad news. You might want to file a bug report and see if the devs have any ideas to track this one down.

There's not much that can be done now, beyond figuring out what exactly happened.
