cant make pool from my disk

[Leopard]

Hi, I break something but not sure how to fix

I have played with truenas some weeks while waiting IT mode SAS card, did try different types if raids and it worked perfectly, until today...

I had multiple iSCSI targets earlier but now other computer (initiator) say something about "existing signature left on the device" from brand new iSCSI. witch was new to me, but because its just for testing, I planned to redo my iSCSI target... anyway. after 30 min struggling to remove iSCSI (it asked if i'm sure and I had to wrote "r510 iscsi HDD 1-6" confirmation ...but I didn't notice double space between HDD and 1-6) so it didnt allow me to.

So *only option* I had was to do 'dd if=/dev/null of=/dev/mfid1 bs=512 seek=1' to be sure its clean.

Well, after that, what ever I do, removing Virtual image from raid controller, trying different sizes raids 5-12Disk (raid 5 and 6) I just can't initialize bool or add disk on iSCSI target on truenas.

Now I have no idea what to do :(

Try wiping the disk(s) from the storage menu
I would also remove the iSCSI config data and start again

Ah, was my own fault, I double check Block shares (iSCSI) again and I *think* it was extents what I was forgot to clear, but weird because I did raidconfig multiple times (Could it be that when iSCSI is pointed to device, as long device path is same, it doesnt mind?) Im newbie with iSCSI.

After all, now I can redo my share and can mount it on proxmox...
sadly its read only for VM's, but that seem to be proxmox conf error ^^
