Time Line Fo A 4tb
Sorry to resurrect an old thread, but this thread seems most appropriate for a follow-up question. Any general comments about how long it takes to add new disks versus how long it takes to replace an existing disk with a larger disk? The reason that I'm wondering is because I'm considering getting a DS1812+, which has 8 bays.
I have a mix of 3 TB drives and 2 TB drives. I plan on using SHR with either 1 disk or 2 disk redundancy. By the end of the year, I forecast that I'll need to have 3 TB or greater drives in all the bays to meet capacity needs. So, one option is to just put the 3 TB drives in now, and leave some drive bays unused, and then add 3 TB or 4 TB drives in the future as capacity needs grow (and disk prices get cheaper). Alternatively, I can fill up all drive bays with 3 TB and 2 TB drives.
Then, in the future, I'll replace the 2 TB drives with 3 or 4 TB drives when capacity needs increase. Hence, my question: is it faster to replace an existing drive with a larger drive? Or is it faster to add new drives to unused bays? I also read in a Synology Wiki page ( ) that 'during the Volume Reshaping process, there will be no parity protection to the Volume, thus any disk error or power failure may result in the destruction of the Volume.' However, not sure if this information is up to date or is outdated. If this information is still true, then it seems that it's better to just fill up all drive bays with whatever disks I have and then replace (instead of add) disks as capacity needs increase. Comments/thoughts, anyone?
Nice speech, BSpielbauer, but not exactly accurate. I have a DS415play that had 2x1TB and 2x4TB drives.
I bought two additional 4TB drives to replace the 2x1TB drives. I swapped the first 1TB drive with a 4TB one about two days and 6 hours ago, that's way over 50 hours now and the unit is at 38% now. Meanwhile I can access the contents of the unit using Finder (I'm a Mac user), but it is refusing to do its main purpose; stream video. The DS Video apps on my iPads and Android phones refuse to play anything because of 'insufficient disk space' though there is over 1 TB free space even before the expansion.
Time Line For A Wedding Reception
The only way to play videos now is using a regular computer and just load the files over the network and play using VLC. So although your story about availability for corporate use makes sense, it's rather silly for a consumer unit (which the 'play' is) to need a freakin' 5+ days to expand one 1TB drive to a 4TB -and- be unable to stream any videos to DS apps on iOS, Android or Smart TV. I would rather have either full availability and for all I care take 10 days to expand -OR- no availability at all and expand within two days max. This is just the worst of both worlds now and entirely not what I expected from this otherwise great Synology product. This unbelievable. I have a DS916+ with two 6TB HDDs.
I made the mistake of adding a third 6 TB Hdd two days ago and the NAS is now basically unusable. I tried changing the default ports for security reasons and the new changes don't save. Also, my PLEX server folder in my shareable folder is gone!! The NAS dives have been running for TWO days now and, from what I've read here about 2TB drives, I'm not expecting the HDD addition to finish until 2019! Does anyone have any suggestions on how to interrupt this process as I'll begetting another brand NAS as an alternate to the 916+ because I need to have my NAS fully operational 24/7. Thanks in advance. Fully agree with Squozen.
On any system that is both in operation and in rebuild of the raid you should have some patience: 6-12 hours/TB is more a rule than an exception. In case you want to speed up the process, there is only one way: make sure nothing reads/writes to the disks. If you have any 'out of office hours' you can shutdown all processes and restart them in the morning eg via task manager. Especially the cloud sync, cloud server download station, web server and the likes will slow down the process. If your business cannot handle the performance dip, your only possibility is a mirrored hot spare at standby.
Thanks for your replies. The addition third drive took four days to configure. I don't think that I'll be adding the fourth hdd for a while. Synology should add a time line to show the status of the expansion, not just the parity percentages. And, somehow, after the hdd expansion, my Mac mini doesn't see the NAS anymore and so Finder can't connect to the NAS due to 'the server may not exist or is unavailable at this time'. And so, contrary to some reports that the NAS was still usable during the expansion, something wnet terribly wrong. Everything else seems to be working fine.
Linux mint download ftp for mac. I just can't share my files anymore from my Mac to the NAS. Support suggested that I restore any saved config file, which I'm thinking of doing. I realize that the NAS configs setting reside in their own partition separate from the data ones. But here's my concern before I do anything. If I saved the config file BEFORE I expanded the storage (the third hdd) will restoring it now (after the expansion) will there be any problem? Thanks in advance.
