Hi there,
I am trying to find out if it is possible to import my existing ZFS pool into TrueNAS.
I currently run my Ubuntu 20.04.3 as a virtual VM on ESXi, where I have presented a hardware SAS HBA card (LSI SAS3008) to the VM.
I have also added some virtual NVME disks for cache.
Right now I am running a raidz3 with 24 disks which are installed in a NetApp DS4246 shelf.
I then have a read cache consisting of just one NVME virtual disk.
Because speed on large directories is important to me, I have created a mirrored "special" vdev which consists of two virtual NVME devices as a mirror (of cause on two different physical devices).
Another nice feature (I think) is that I have added some vdev_id's so that I can see which slots my drives are in... which is handy when replacing disks.
My ZFS versions looks like this:
zfs-0.8.3-1ubuntu12.12
zfs-kmod-0.8.3-1ubuntu12.12
And my pool looks like this:
The question is of cause, how much of this can be added into TrueNAS ?
Here I am especially thinking of the "special" vdev, and the vdev_ids...
