Problem updating my NAS

[flameproof]

Synology has a really good and active forum, here:

yes, a bug obviously.

I've encountered this problem too.

Do you have Plex installed? If so, disable or uninstall it first, then upgrade, then reinstall it. I think Plex is killing the upgrade from DSM 5 to 6. Also better check plex website for latest version of plex, they only recently upgraded the plugin to support DSM 6.

Buy 4 new hard drives of larger capacity. Replace the old ones, one by one. Letting the RAID set rebuild between each disk swap.

This will take ages (days is my guess).

Take a backup before you do this in case the RAID rebuild barfs.

How big are the disks in your DS415play now? eg if you have 4x3TB disks then replace them with 6TB and double your space. As jgl suggests, replace them one by one a few days apart and the system will automatically rebuild itself after each disk swap. But if you pull out 2 disks at once you are screwed and lost everything. So it is quite a risky exercise and better know what you are doing.

With synology, you can have drives of mixed sizes too. So if you have 4 x 3TB in their now (total 9TB), you can replace just 2 of them with 6TB drives and you'll get 12TB. No need to replace all 4 drives at once. But you must upgrade at least 2 of the 4 drives, if you do only one you'll still get only 9TB (the largest disk in array is used for protection).

If you have RAID 10 it should be possible to swap the drives too since you basically have a backup of everything. I think it should also be safer since your data is already backed up. I guess if you have 4x3TB, swap drive 3 and 4 with new 6TB versions and then let the RAID backup again. Once done, swap drive 1 and 2 with 6TB versions. I don't have a Synology drive and never tried it, but basically it should work.

Nevermind, just read the forum, no can't do. Not sure why, haha.

I looked for a non-Synology solution online. They say it's possible, replace drives one-by-one, then expand the overall volume at the end using some disk management tool to expand it. So it could be that the last step is not supported by Synology. If you're gutsy, just try and see what happens,

Or, you buy a new one and I buy your old one.

Do you really need RAID10? That is not really a normal home user setting. It gives you extra protection (2 disk fault tolerance) but you lose 50% of the space. If you switch to SHR (1 disk fauly tolerance), you still have protection but only lose 25% of the space.
