I have an Ex4100 with 2x4TB drives configured in RAID 1, in drive-bay 1 and 2. I then added 2x12TB drives in drive-bay 3 and 4, also configured in RAID 1. When I did this it created a second RAID Volume. Is there a way to combine these 2 Volumes so that all 4 drives are on a single RAID 1 Volume?
Now I see the new capacity when I log into NAS. However, the drives on my Windows PC that were mapped to this NAS still show the old capacity.
It seems that all my usable space is still increased. Can someone shed light on this situation? Thank you.
I don’t think you can do a Raid1 configuration with 4 drives. You would do a raid 5 (or whatever) that stripes data (not mirror) across all four drives. The advantage is that you get more usable space. HOWEVER; this doesn’t really work with drives of different sizes. (it would treat the raid as 4x4tb drives. . .which is suboptimal)
Long way of saying: NOPE. You are stuck.
Note that any change in raid configuration will result in a drive wipe.
Sorry for the bad news.
“The drives on my windows PC that were mapped”. By default; your original volume (and it’s mapping) would be unaffected by adding second volume. You have to independently map the second volume to use it with the PC. (the second volume is literally a second drive in the Windows world)
Thank you @NAS_user .
How does one map the second volume to my PC that will be a reasonable solution where I can manually split the contents onto the two drives. Sorry for the basic question.
I am asking how to map the second volume because my mapping is based on “users” and not on the specific volume on NAS. I don’t even see any volume information from my computer. I only see it when I log in to EX4100 directly from a browser. Thank you again.
ok. . . where to begin.
First… . .recognize that windows has a limitation in that a single network resource can only use one set of credenitals. So if a single PC is uses Tom and Richard. . . .their shares better have the same username and password; or you will have problems.
Second, in File explorer;
in the “navigation pane” on the left side. . . scroll down to network. Under network, you should see the NAS and all the “shares” that can be seen by the computer. Each share you create, regardless of volume, should be visible here.
Click on one and log in. Remember you will now have access to all the shares that use that set of credentials. Windows won’t let you log onto a share that uses different credentials that is at the same network address.
The two volumes are relevant only that it forces you to create shares on each volume. . .you can’t create a share that spreads across both volumes. So. . .my pc shows one share for the NAS; because I have a single volume. You will show a minimum of two? or as many as you create on the NAS.
Thirds, to map a drive; in file explorer; in the left side navigation pane; click on the COMPUTER You will notice the menu options will change. Click “computer” menu choice, and then you will see “Map Network drive” in the middle of the ribbon.
Hope it helps.
Thank you very much @NAS_user . The above statement clarifies a lot for me. Thank you.
