storage manager

I have tried to add 2 different 8TB drives to my DS218+ (one at an time) and each time the Synology refuses to add the drives, claiming they are ‘failing’. I’ve putlled the drives, reformatted them on a cmomputer, scanned them, and they are both fine (brand new drives from different...

I am trying to install a new HDD in my DS1515+. The hard drives are brand new Seagate Exos X. I have bought 3 of these drives, and 1 of them works fine and is now part of my storage pool, but the other 2 gives me an error when I install them in the DS. The error is "Multiple reset command...

On my 920+ I had been running three, 3 TB Drives in SHR Mode..... I now added two 4 TB Drives as one of the 3 TB's may have been on its last legs. I deactivated that third suspect drive, Installed the new 4 TB in its place and allowed it to REPAIR and DATA Scrub. I then added the 4th 4 TB and...

Have been alerted [scared] by @jeyare about RAID 5 (SHR-1) potential for failure during rebuild due to unrecoverable read error (URE) when accessing disk sectors. The likelihood of this occurring increases the larger the RAID size. So given that in RAID 5 you have to reconstruct the missing data...

Hello, I am still experimenting with my new NAS DS220j. And now after I removed everything from all my drives, and empty all recycle bins, and deleted all Shared Folders, the Storage Manager still tells there is 524,5 GB in use. Before removing everything there was over 1 TB in use. And I...

Being new to >2 bay NAS I hadn't seen the Hot Spare options before. Now I'm thinking about current usage but also migrating the RAID in the future. A few questions occur to me: The documentation lists the RAID types that are supported for Hot Spare. I use SHR-1 and this is omitted from the...
