I’m having a bit of a problem understanding how much disk space is actually in use.
I have 24 512 gig drives. Setup in 6, 4 drive RaidZ2. So raw storage that should leave me with roughly 6TB
In this jpg the “Size” is what was provisioned. This has no relation to the reality of how much physical disk space is on the machine, correct?
Under ”Available” this IS what is physically available disk space on the machine?
The /tank1/iscsi-groups doesn’t show anything as Used or available. So i’m assuming no matter what is in there i need to write off the 1.50TB of space?
Tank1 says 1.7Tib used. Is this the total of all the stuff stored in tank1? So esx and ISOs?
So if this all works like i think it does I should be able to add up what is used in tank1, what’s available, and the space reserved for the iscsi groups and come up with the grand total of disk space in the machine.
So:
tank1 - 1.7TiB
Available 1.3 TiB
iScsi 1.5T
= 4.5TB
So i don’t understand what i’m missing. Anyone have any ideas?
