Trouble in Synology land again. File System Errors.

Another day, another Synology issue :) I mean for my Synology server, that is..

But to be fair, this is a pretty old Synology DS1515+ already and has been well used. Every single day. Receiving tons of movies, TV serials and then playing them to multiple TV systems, Amazon TV players etc. Been a nice good friend for a while :)

Anyway, this time the issue is “File System Errors were discovered. We recommend running a file system check”.

Was alerted to it when I logged on to the Synology DSM (remotely at that). I do that regularly to check for updates and see if I have enough hard disk space (from the photo below, you can tell i am starting to run out of space again :p).

Saw that there was an error notification. Disk 5 is having problems. Coincidentally, disk 5 is the only Seagate hard disk in an array full of Western Digital RED disks.

Going to the Storage Manager, more scary messages :)

All this time, the Synology was running fine and still serving the wonderful MKV files and RMVB files and MP4 files to my un-suspecting family of Hong Kong TV addicts….

So I took a deep breath and click on the “Run a File System check”. I did not take a screenshot of the next message but basically it told me that it will take a while (something like 15 – 30 mins per TB and I have 10 TB or more ?). And that the system will need to reboot. Now that last part is scary. Scary in that I must inform the whole family that it is time to sleep and no more crazy Hong Kong TVB shows for the night. That is not a nice message to give :)

The next day, an even more scary message met me in the morning

Okie. This is not fun.. Checking the rest:

I have no more choice. Clicking on the REPAIR link and was preparing for a day or two of repair.

Surprise.. it was over in couple of seconds… literally, just click and the next second, everything is back to normal.

Everyone is happy again.
