Hi Karim,
All ZFS storage pools are going to use some amount of space for
metadata and in this example it looks like 3 GB. This is what
the difference between zpool list and zfs list is telling you.
No other way exists to calculate the space that is consumed by
metadata.
pool space (199 GB) minus avail file system space (196 GB) = 3 GB
The db-smp.zpool/db-smp.zfs is consuming 180 GB and the
db-smp.zpool/oraarch.zfs is consuming 15.8 GB, which adds up to 196 GB.
This pool is full so you need to reduce the space that the file systems
are consuming or add more disks to the pool.

Hi,
Im Karim from the Solaris software support, i need a help from your side
regarding this issue :
Why ZFS is full while it's zpool has 3.11 Go available ?
zfs list -t filesystem | egrep "db-smp|NAME"
NAME USED AVAIL REFER MOUNTPOINT
db-smp.zpool 196G 0 1K legacy

1) Why doesn't the space that is reported by the zpool list command and
the zfs list command match?
The available space that is reported by the zpool list command is the
amount of physical disk space. The zfs list command lists the usable
space that is available to file systems, which is disk space minus ZFS
redundancy metadata overhead, if any.
**
if this doc can explain the above issue, how can i know (calculate) the
zfs redundancy metadata?how can i know if it exists?
otherwise how can we fix the above problem.
I appreciate your help
regards
A.Karim
