Earthian E90 Posted July 22, 2020 Share #1 Posted July 22, 2020 Hi All, I am relevantly new to the project, and here goes my first post. Hope it goes well I have installed the DS918+ a few months ago. Against all the warnings, I installed version DSM 6.2.3-25423 Everything was going great. I created a volume, good Installed some packages, good Drive in volume died, replaced drive, all was good (this happened twice) Now I face an issue which kind of scares me. An SSD which is not part of any volume is failing. I don't remember the setup process 100%. I think the DSM and all its packages are installed on the drive that was connected during setup. Please correct me if I'm wrong. This is the drive that is now failing. Is it possible to replace this drive without loosing all data? Like, can I introduce a "HOT SPARE" to replace this drive or is a complete reinstall required? I don't remember the exact hardware spec at the time of writing this. If necessary I will go look it up. Any help would be appreciated. Thank you for reading. Quote Link to comment Share on other sites More sharing options...

Nothing wrong with DSM 6.2.3, just some concerns (largely resolved now) for upgraders from previous versions. You don't show how the problem drive is being used. Can you print screenshots of your Storage Pool and Volume configuration in Storage Manager? If it isn't being used, it isn't much of a risk. In any case, DSM is installed on all drives. So failure of this drive is unlikely to make you lose data immediately unless you have provisioned it as a single non-redundant Disk Group. Furthermore, it looks like the drive in question failed a SMART test, but isn't showing any bad sectors. Look at the SMART Attributes in the Health Info page for the drive, and see if it tells you anything useful. 1 Quote Link to comment Share on other sites More sharing options...

After a very long day at work it is very nice to come home to some good news! This drive is not part of any volume and is not in a storage pool. I was under the impression that DSM was installed on it, so I just set part of it as SSD Cache and that's it. I thought the drive was going to die and take my NAS with it so I quickly removed the SSD Cache to reduce the drive usage. Looking at the S.M.A.R.T results nothing seems bad or maybe i just don't understand what I'm looking at. I have attached some more screenshots, maybe you can see something that I missed? I will try to remove the drive and hopefully everything will continue working as is. In any case, thank you so much for your helpful input. Have a great weekend Quote Link to comment Share on other sites More sharing options...
flyride Posted July 23, 2020 Share #4 Posted July 23, 2020 Ok, it failed a quick test. It doesn't really say why. The SMART stats look fine. Try manually running another quick test through the UI, and if it passes, the errors will be gone. Quote Link to comment Share on other sites More sharing options...
Earthian E90 Posted July 23, 2020 Author Share #5 Posted July 23, 2020 I failed again 😕 Tomorrow there is a scheduled "extended test" If it fails that as well Ill just disconnect it and try testing it on another system. Thank you again! Quote Link to comment Share on other sites More sharing options...
Earthian E90 Posted July 25, 2020 Author Share #6 Posted July 25, 2020 Now that's odd. Quote Link to comment Share on other sites More sharing options...
flyride Posted July 25, 2020 Share #7 Posted July 25, 2020 I've had DSM flag drives as problems before, I'd run the Quick Test a few times and see if you can get one to complete. Also I notice that the drive is (and has been since the beginning of this thread) "Not Initialized" which means it doesn't even have DSM on it - no partition structure. So nothing to be lost. If you cannot get it to clear, we may be able to purge the failed Quick Test record using the command line. Quote Link to comment Share on other sites More sharing options...
Earthian E90 Posted July 25, 2020 Author Share #8 Posted July 25, 2020 After running another "quick scan" the status turned to warning Then I pressed the "Suppress drive warning" in the drive health overview. That seemed to cure the drive and it is mounted as SSD Cache once again. Thanks again Quote Link to comment Share on other sites More sharing options...
