February 14, 20251 yr Hi, I am using a 1 TB SanDisk Extreme Pro SSD as Cache (sda, xfs Filesystem). But it only shows 256GB Size, (of which 119 GB are used and 137GB free). Any idea where to look for the missing 744 GB? I searched the forum without success, any recommendations? Thanks a lot! latest Unraid 7, if I should post other log files, please let me know.

February 14, 20251 yr Community Expert What do you get from command line with this? fdisk -l /dev/sda

February 14, 20251 yr Community Expert I don't understand your lsblk output. Why is /var/lib/docker mounted there? Disable Docker in Settings and do lsblk again.

February 15, 20251 yr Community Expert Partition looks correct, but looks like the fs is not using it all, try typing this with the array running: xfs_growfs /mnt/cache Then restart the array.
February 15, 20251 yr Author Solution you are the best! Thanks a lot, this worked, full 1GB is available again! Thanks for your friendly and fast support! Team Interlagos rulez!!!! Best, Michael
