I would contact Sy...@MarkoLarko, I feel you pain! <br /><br />I would contact Synology support. They should be able to assess the situation and help you determine next steps.

What an interesting Blog. ...All these tales of woe!<br />What an interesting Blog. Firstly it was a joy to read because you were able to encapsulate all the mental and emotional trauma that a failing Synology (NAS) has on one....especially when you realise that your backup strategy is unsustainable. However moving swiftly on ...<br />I have a DS 1515+ with an expansion bay with 10 x 4tb drives with one Hot Standby. (That is a completely filled Synology = 5+ 5) in all 27.9 Tb of which I am using 19.3 Tb.<br /><br />Three days ago I had a warning saying that my Synology was crashed! Crashed in RED!<br />I could feel the adrenaline surge and it was not a good feeling.<br />(90,000 photos, 48,000 music tracks and 1,000 movies).<br /><br />I immediately went online and realised that the network access was available and I immediately copied my Photos to another external drive. Followed this with the music library. Went to bed and mysteriously nearly found myself wanting to kneel beside my inviting bed but the feeling passed very quickly. Didn't sleep well that night (2 nights ago!)<br />In the morning the external 'HDD' which I was copying the Photos to was 'CLICKING' in an ominous joking sort of repetitive way. F***!<br /><br />The Synology was still active but I could only see the File Structure of my NAS - none of the contents were available or visable!<br /><br />I decided that I needed to shut down the NAS as there was no alternative. The NAS was as good dead.<br /><br />So with a little trepidation and feeling gungho at the same time because 'shit had happened' I pressed the power button on the 1515+ When I rebooted a few minutes later the drives started flashing except for the two 'failed' ones. (They were Bay 5 and Bay 5 on the expansion box)<br /><br />I noticed that the drives LED were no longer Orange/Amber. They were Green - but were not flashing. The rest of the drives were going mad. I logged on and 'Wooow' I had my Synology back and the error message was 'Repairing'<br /><br />The Green lights on Bay 5 and Bay 5 Ex are now flickering away as if they were part of the recovery process. This I thought was pretty strange as to all intent and purposes they should be isolated from the building process. Maybe I am wrong? <br />Do I assume from the lights on the drives that the rebuild process still has access to the data? I originally had 9 HDDs with one hot spare (HS). The HS seems to have picked up the slack but what of the other two drives? One is saying 'System Partition Failed' and the other is saying ''Not Initialised' with a health status of 'Warning' with 1 Bad Sector.<br /><br />How you can get a Warning for a Sector when the disc is supposedly 'Not Initialised' I have no idea?<br /><br />SO I have ordered a spare Red 4Tb drive (Not next day delivery as this machine is only 50% rebuilt after 35 hours!) and by the time it arrives everything will hopefully be back to 'normal'<br /><br />So my question to all you readers is what do I do next?<br /><br />I will have 2 HDDs which are suspect and a spare on the way. Do I remove (Hot Swap) the Not Initialsed HDD with the new HDD or what? <br /><br />I am confused as to whether the HDD are failed or just a bit 'muddled' and need to be reformatted / cleaned ready for re-insertion? The real problem is that I can find no definitive advice on the best way of proceeding.<br /><br />I have a day or two to contemplate this but if anybody any bright ideas for a frustrated Cornish Grandfather then I will be all ears.MarkLarkohttps://www.blogger.com/profile/11703426743464451578noreply@blogger.comtag:blogger.com,1999:blog-6691994129222744759.post-41134826037062040912018-06-29T17:53:54.893-07:002018-06-29T17:53:54.893-07:00Similiar story with a 411j.

But status was Normal unless one looked for this. Ultimately, it started running a parity check and slowed down and became unresponsive in a very similiar way to this story. Likewise, very long times and unresponsive. This unresponsiveness is very poor. <br />Learnings:<br />- have notifications via email with bad sector reports!<br />- don't leave drives in there for too long.<br /><br />Unknownhttps://www.blogger.com/profile/13582934833748573286noreply@blogger.comtag:blogger.com,1999:blog-6691994129222744759.post-880902725517187892018-06-24T16:57:58.072-07:002018-06-24T16:57:58.072-07:00Hi Steve,

Applied same process (except the hard reset that I have done and install dsm 6.2 and it works. Took me a week to figure it out since I found your post only after repairing it. However, now I have followed your advice and I have 2 hot spare.Anonymoushttps://www.blogger.com/profile/13962732395147504583noreply@blogger.comtag:blogger.com,1999:blog-6691994129222744759.post-42788979080588062342017-09-10T07:42:02.834-07:002017-09-10T07:42:02.834-07:00Hi Daniel,

Synology have enabled the "Enable ...Hi Steve, <br />Synology have enabled the "Enable Bad Sector Warning" setting by default on new installations of DSM. I recently bought a 916+, and after reading your article, i checked the "Enable Bad Sector Warning" setting and it was indeed enabled. The number of sectors was set to 50 however. I also have a DS411J which I have kept up to date over the years, and the setting was disabled. It's a shame they do not switch it on when upgrading, then ignore it afterwards.Anonymoushttps://www.blogger.com/profile/17507368683384280326noreply@blogger.com
