ZFS cache pool - moving files between folders slow, like its actually doing copy instead of move

Featured Replies

hi guys,

 

i recently upgraded my cache pool, decided to make it a 3 disk ZFS pool.

before this i had been using a regular xfs single disk cache pool.

 

with zfs cache pool now, when moving files from a /user/temporary folder to another /user/destination (both are cached shares) it seems to be doing an actual move or a copy. i checked and confirm it is still moving files within the cache pool, not moving anything to the array. so everything is actually happening within the cache pool.

 

previously moving files like this happened instantly since the move only happened within the cache pool, then only later mover would move the files to the array.

 

is this the expected behavior for zfs cache pools?

 

i'm using unraid 6.12.6 and moving files using midnight commander in a terminal window or putty.

This is normal if they are datasets, by default any share create on zfs storage will be a dataset.

i was afraid that would be the case... i guess that's one drawback of ZFS for me.
