My DS409slim is really slow since I faked it as a DS411j and installed DSM v5 on it. An option could be configuration issues. So I decided to reset the whole configuration. But I need to keep all that are stored on the SHR-RAID. It is quite straight forward. But here’s the no-so-short story.
Locate the reset hole at the back of the DS409slim. Quoting the doc: ” (…) Using a paper clip, gently press and hold down the RESET button for about 4 seconds until your Synology NAS emits a beep sound. Within the next 10 seconds, press and hold down the RESET button again for about 4 seconds until your Synology NAS emits another beep sound. You will see the STATUS light on your Synology NAS’s front panel now blinking orange. Run Synology Assistant and find your Synology NAS. You will see Configuration Lost under Status.”
When the reset is done, I could log-in to the Web interface and check that data were still there on the disks. Hurra!
Now, I’ll give it a few days or weeks to prove it can handle DSM v5. If not, I’ll go back to DSM v4.
