zpool more than 80% but ZFS SAN storage is still lower than 80% will it affect performance?

984266Jun 13 2013 — edited Jun 14 2013

HI All,

As we know, in ZFS, it is recommended to keep the disk usage below 80% to ensure the performance.

However, the following is my scenario:

I have a ZFS storage, which share by multiple servers, and overall Usage is lower than 80%.

Server A has multiple  Lun (spool) from this storage, For example:

- LUNPOOL/A

- LUNPOOL/B

- LUNPOOL/C

Currently, LUNPOOL/B of server A is more than 80%, it reach 88%.

Since the overall storage there still lower than 80 %,  will the performance for this LUNPOOL/B be affected?
