ReadyNAS314 - Access Extremely Slow

Question

ReadyNAS 314 - F/Ware 6.10.4 hotfix 1 - 4 x 4TB WD Red in XRAID

This has been working fine for a number of years - until the past week or so.

Network drives mapped from 4 different Win10 PC's would be lost - couldn't log in to NAS admin - needed to be powered off and back on. Would then work fine again for a day or so, then do the same thing.

Have deleted some files to increase space (currently 3.05TB available from 10.90TB).

Can now access admin page and also mapped drives - however, can only drill down 2 or 3 directories until it becomes unresponsive in Windows File Explorer. If it is left running,it will eventually open next level directory - but it takes over 5 minutes.

Log files don't indicate any errors and no disk errors shown.

Anyone seen this before....?

Thanks,

JB

Did you look in the log zip, or just on the screen?&nbsp; There's a lot more in the log zip.

Sluggish performance is generally linked to performance issues with&nbsp;

disks
network or
NAS CPU/Memory

looking for disk and btrfs errors in system.log and kernel.log can be helpful (if you haven't done that already).
&nbsp;
Looking at tx and rx packet stats in network-settings.log will give you clues on the network performance.&nbsp; One thing to try is grabbing the log files before and after a transfer test, and compare the stats.
&nbsp;
On CPU/Memory, one thing to try is disabling your apps (and antivirus and file search) and see if that makes any difference.&nbsp; You can also enable ssh, and run top.
