Description

RAID Resync Priority

Specify the priority level for the following RAID operations when the NAS is in use:

  • Rebuild

  • Scrubbing

  • Sync

You can select one of the following priorities.

  • Service: When selected, QTS performs RAID operations at lower speeds to maintain NAS performance.

  • Default: When selected, QTS performs RAID operations at medium speeds.

  • Resync First: When selected, QTS performs RAID operations at higher speeds. Users may notice a decrease in NAS performance.

Important:

When the NAS is idle, all RAID operations are performed at the highest possible speeds.

RAID Scrubbing Schedule

Enable this feature to periodically scan for and automatically fix bad sectors on RAID 5 and RAID 6 groups. For details, see Running RAID Scrubbing on a Schedule.

Auto Reclaim and SSD Trim Schedule

Enable this feature to periodically run the following tasks on all thin volumes and SSDs:

  • Auto Reclaim: QTS returns unused storage space to the parent storage pool. The unused storage space is derived from files deleted from thin volumes.
  • SSD Trim: QTS cleans deleted data blocks to maintain SSD read and write performance.

By default, the operations are scheduled to run daily at 2:00 AM. SSD Trim is only performed on solid state drives if they are in a RAID 0, RAID 1 or RAID 10 group.
