no space on device (64GB USB BOOT)

[sharpusa]

So freenas has been working fine, my volume1 has 10TB (connected to client machine via iSCSI)
Freenas is on a fast 64GB USB. System is an Intel XEON CPU with 16GB RAM ECC. Storing only backups.

After scrub started I ran out of space, I even updated to the latest freenas last night, rebooted, still out of space.

Attached is a log message.

Your data pool -- volume1 -- is 100% full. You need to either free up space, or add more storage.

 

[sharpusa]

Will I provisioned to use 10T when I originally setup freenas, and I do have 7TB available on the iscsi map.

 

[pirateghost]

So you allocated 100% of your volume to iscsi?

And you wonder where your space went?

 

[sharpusa]

How much space would I need free for Freenas? I was assuming the 64GB USB is were the logs will be storing on, not on the actual volume1 where I store my backups.

Well all the warnings and documentation indicate you shouldn't let your pool get more than 80% full....


So you allocated 100% of your volume to iscsi which is full allocation and not thin provisioned which means you filled the pool/volume regardless of what your iscsi disk shows available.

As the documentation states, freenas makes a .system volume for storing logs...

You are right, I'm trying to reduce the size from 10T to 9.5T, but doesn't do anything, do I have to delete the volume and start again?

You were assuming incorrectly. The logs and other related data are stored in the .system dataset, which goes on whatever pool you configure in the web GUI. By default, it goes on the first data pool you create. I don't know if it can be placed on the boot pool at all (though I'd discourage it--lots of r/w activity is not good on USB sticks), but that certainly isn't the default.

You will have to delete the iSCSI zvol/file and recreate it as a smaller size. But it should be only 50% of the total size of the pool (so about 5TB) maximum for performance reasons.
