This is also true of other filesystems however. I don't have experience with high IO on ZFS at those rumored 80%+ capacities however once a core filer fills up

This is also true of other filesystems however. I don't have experience with high IO on ZFS at those rumored 80%+ capacities however once a core filer fills up to 90% you start seeing the tickets rolling in and application performance tank. 80% if usually fine however. I wonder to what degree the performance degradation is on OpenZFS.
- throwaway7767 10y agoThe problem is much more severe on ZFS and other CoW filesystems, hence the common warning. Filling an ext4 filesystem up to 80%+ and then removing files might increase fragmentation a bit but it'll not have that much effect on performance. On ZFS, filling the fileystem up once can kill performance permanently on that pool.
