Unable to see/locate .ix-virt dataset

TrueNAS General
,
1

Chain of events:
Updated to Fangtooth on release. Selected a pool for instances.
Rolled back to EE to fix some dataset/pool and app issues. Noticed the ix-virt dataset was visible in the webUI, deleted it as it was part of the pool that was giving me issues. Updated again to Fangtooth a few days later. Selected the new pool for instances.

I am not having any issues with instances at the moment but, I was curious as to where the ix-virt dataset now resided. I am unable to locate it, even when searching for hidden paths. ls -a or ls -lah I see it mentioned in the source code and in the TrueNAS documention so I am stumped.

Any help would be appreciated.

try zfs list

it is hidden from the gui.

Thank you @Stux! That allowed me to see the dataset.

Can you, or someone else explain why zfs list would show the path but ls -a or ls -lah would not? When I research what each one does respectively, it is a bit beyond my understanding.

The mountpoint is ā€˜legacyā€™. Does this mean it is no longer handled by zfs or was it never handled by zfs?

ā€œlegacyā€ means it gets mounted manually using the mount command (like most legacy filesystems), rather than automatically at a predefined mountpoint

The point is, Incus does it. Donā€™t worry about it.

The important thing is the dataset, which is a filesystem, doesnā€™t get mounted in the normal /mnt/<pool> hierarchyā€¦

And this is probably half of the reason why its hidden in the GUI too.

Hi thanks for the hint. Is there also a possibility to copy a zvol from this hidden folder to another place?
Since I rolled back from Fangtooth to ElectricEel I am not able to mount the zvols from my VM. Unfortunately during the VM migration in Fangtooth I moved them instead of did a copy.
Is there any solution for my problem?

Hi, did you resolve this?

I donā€™t know what i did the original conversion, but I donā€™t have any files now, after I upgraded and the old ā€œVirtual Machinesā€ is back.
But i get a list with this command:
ā€œzfs list -t volumeā€.

It is but you still wonā€™t see it with ls. A zvol is an artifact in ZFS, not a file. You can only see it or perform operations on it (snapshot, rollback, clone, copy, delete, ā€¦) with zfs commands.

This way worked for me.
