an example to show, that is is possible to allocate hugefiles (bigger
than a single disk size) from a pool:
> datakanja@PBuster-NFox:~$ mkdir disks
> datakanja@PBuster-NFox:~$ cd disks/
> datakanja@PBuster-NFox:~/disks$ seq -w 0 15 | xargs -i truncate -s 4T
> disk{}.bin # this creates sparse files to act as virtual disks
> datakanja@PBuster-NFox:~/disks$ zpool create TEST raidz3 ~/disks/d*
> datakanja@PBuster-NFox:~/disks$ zpool list
> NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH
> ALTROOT
> TEST 64.0T 314K 64.0T - - 0% 0% 1.00x ONLINE -
16*4 TB = 64 TB size
> datakanja@PBuster-NFox:~/disks$ zfs list TEST
> NAME USED AVAIL REFER MOUNTPOINT
> TEST 254K 50.1T 64.7K /TEST
# due to redundacy in the pool, the maximum size of a file is slightly
over 50TB
#do not forget to clean up (destroying pool and files)
