I have a FreeNAS server with 3 x 2 To disks in raidz1. I would expect to have about 4 To of space available. When I run
zpool list I get:
[root@freenas] ~# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT main_volume 5.44T 3.95T 1.49T 72% ONLINE /mnt
I was expecting a size of 4 To.
Also, used space as reported by
zpool list does not match what's reported by
[root@freenas] ~# du -sh /mnt/main_volume/ 2.6T /mnt/main_volume/
There are quite a few things that I dont yet completely understand about ZFS. But at the moment I am mostly worried that I misconfigured my system and that I dont have any storage redundancy. How can I make sure I did not do an horrible mistake ...
For the sake of completeness, here is the output of
[root@freenas] ~# zpool status pool: main_volume state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM main_volume ONLINE 0 0 0 raidz1 ONLINE 0 0 0 gptid/d8584e45-5b8a-11d9-b9ea-5404a6630115 ONLINE 0 0 0 gptid/d8f7df30-5b8a-11d9-b9ea-5404a6630115 ONLINE 0 0 0 gptid/d9877cc3-5b8a-11d9-b9ea-5404a6630115 ONLINE 0 0 0 errors: No known data errors
