Some drives. I think the need to be sata 3.3v compatible. I tried a 6TB RED that I have and it wouldn't spin up.and yes you could then put another drive in and use it as an external.
as it's not destructive (no sticker to remove)
Do you know what's inside 10tb models
Is there a way to confirm this for sure when having the disk
fio --name TEST --eta-newline=5s --filename=fio-tempfile.dat --rw=randwrite --size=500g --io_size=1500g --blocksize=10m --ioengine=libaio --iodepth=1 --direct=1 --numjobs=1 --runtime=3600 --group_reporting
efax = smr and efrx = cmr
TrueNAS will do that on its own; it'll treat all disks as the size of the smallest disk, e.g. if you had a 4TB disk alongside your 10TBs all disks would be used as though they were 4TB.Oh, another question, if one of these disks fail, it may not be easy to get the exact same model to swap.
Is Freenas tolerant to disk size variation depending on brand and model? For example this disk is 10tb, but another brand disk is in reality slightly smaller, lt's say 9.9tb. Will it work OK or do I have to manually create the raid using only 95% of capacity?
In his specific example of a 2x10T mirror, does it work that way? I know in the documentation he could replace a failed 10TB with a 12TB and it would keep the 10TB mirror; if he replaced the good 10TB with a 12TB after resilvering, he would get a 2x10T mirror. But if he replaced a failed 10TB with an 8TB would he end up with a 2x8TB mirror? What if it had 9TB of data on it?TrueNAS will do that on its own; it'll treat all disks as the size of the smallest disk, e.g. if you had a 4TB disk alongside your 10TBs all disks would be used as though they were 4TB.
