I upgraded my TS-h686 from QTS.
NVME 2T x2 (RAID0) 1st-tier
SATASSD 4T x3 (RAID5) 2nd-tier
SATAHHD 10T x3 (RAID5) 3rd-tier
RAM 32GB
I was operating with Qtier.
I backed up the data to a USB HDD, set up tiering on QuTS in the same way as QTS, and restored from the backup, but I encountered some issues.
The shared folder I created was set to write directly to the 3rd-tier.
When restoring via HBS3 sync, data was preferentially written to the 1st-tier,
and it wouldn’t write to the 2nd/3rd-tier, making the system very unstable.
The process stopped when the 1st-tier was nearly full, and by manually forcing tiering, the data moved to the lower tiers,
and after repeating this several times, I was finally able to restore.
The same issue occurred when moving/copying across shared folders in Filestation.
I also encountered several other problems:
- The HDD used for backup was treated as a shared folder, and even after removal, it remained as a ghost.
Deleting the relevant shared folder information from /etc/config/smb.conf and rebooting made it disappear.
It’s still quite buggy.
