ReadyNAS 314 Length of Scrub Maintenance
Hi,
I've looked through the previous answers re how long it takes for a Scrub to complete. Most seem to point to turning off Quotas which I don't have enabled. From volume.log the Scrub took almost...
What firmware are you running, and how full is the volume?
There are a lot of posts out there indicating the ST3000DM001 doesn't work well in RAID arrays. So your issue might be drive-related.
Have you checked the disk health (looking at the SMART stats in disk_info.log)? Are you seeing anything unusual in system.log or kernel.log after the scrub completes?
Firmware 6.9.4
Disk health is reported as good with zero errors isn disk_info.log.
Kernel.log is not showing any issues.
Volume is relatively full, with just less than 20% of volume data's capacity free, although still translates into 1TB of free space.
I'll do some reading on issues with this ST3000DM001 although have been running with these drives for the last 4 years or so. Scrub has always been very slow but feels like it is is even slower now.
The plan is to eventually replace all the ST3000 drives with the WD40's.
Thanks.
