Hi all,
I'm running FreeBSD 8.2 with ZFS with RAIDZ configuration. I meet some problems with disk space.
My pool contain 4x 2TO (+ 1 spare)
RAW space with raid : N-1 =~ 6TB
So I obtain a pool size of 5,33TB .
I've got 2 volumes, vol1 and vol2; vol2 is 3 TB size and it's presented in iSCSI. (type volume because fixed size); vol1 is expected to take the rest of the space: 2,33TB (type filesystem).
Nevertheless, I've a lack of space with my pool and vol1. When I run a zfs list, I've no space left on my pool01, and I've only 3,35TB USED.
I read some information about overhead and metadata, but I really don't understand why I've no available space.
Thanks in advance for helping me
