July 5, 20224 yr Just trying find out if this is intended behavior: I have a disk mounted with Unassigned Drives plugin. I am trying to copy its contents to the array. The command I used is: cd /mnt rsync --progress -ra disks/Y5J326NC/BerkesHDD/ user/ManuelBackup/BerkesHDD/ However, rsync fails when my cache is full: 2,457,600 7% 2.23MB/s 0:00:12 rsync: [receiver] write failed on "/mnt/user/ManuelBackup/BerkesHDD/sd_cards/2018 all nikon z6/Simla Shoot/DSC_0442.NEF": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(378) [receiver=3.2.3] rsync: [sender] write error: Broken pipe (32) rsync error: error in file IO (code 11) at io.c(823) [sender=3.2.3] But my settings for that device should start writing directly to the array when the cache is full? Why would this happen? I know I can bypass cache by using user0 instead but I want to know why this is the case. Edited July 5, 20224 yr by tTIKA

You must set Minimum Free for cache to larger than the largest file you expect to write to cache. Each user share has a similar setting. If a disk drops below Minimum Free when writing the user share, Unraid will choose another disk. Except... Split Level overrides Minimum Free.
