When I originally setup my pool I exceeded the 80% volume capacity. I did some reading and from what I remember reading it would be fine if its not a bunch of tiny files getting changed a lot. And I thought losing the 20% ~5.4TiB seemed like to much. I just brought another 20TiB pool online this time maintaining the recommenced 80% volume. Should I move all the data and re-do the original pool while I have the space to do so? All the data is video files for plex.
Fragmentation is showing 10% on that pool via zpool list.
Used space is 94%
Its in RaidZ1 27.21TiB Used and 6.59 TiB available.
Guess I cant post pictures on this new forum yet.
So, 80% rule is good however it depends on what you use the NAS for. Plex is not an issue. You can go up to I believe it is 90% before the slow writing happens.
I think Fragmentation is kind of funny since ZFS tosses the file in pieces to all the drives in the pool so it is fragmented from the very beginning. But if you want to get the fragmentation back down, move all your data off the pool, then copy it back on. You should not need to destroy your pool and recreate it.
If you use snapshots, clean those up as well.
Yes, new users can do very limited things. You have a limit on how many posts you can do in a day as well. Don’t use them up making another post here. Whatever you do is fine.
Will shrinking the volume in windows do anything to mitigate reaching the 90% since I have it at 94%?
To be honest, I don’t know what you are talking about so I cannot answer that question.
This volume is shared over iscsi so I can shrink it on the windows side with disk management.
See if that works, I have no idea to be honest.
