Hi guys!
Yesterday I found back some of my old spinning drives. I chained them to a JBOD-setup via Disk Utility. As you can see the total amount of storage tops of at 9TB (the sum of all the hard drives).
BUT in Finder I could only see 4TB, so I went back in Disk Utility and saw there also only 4TB under JBOD (container size).
What happened here and how do I fix this? Formatting the drives again is no issue because I have the data also somewhere else.
Thanks!
While you’ve named it JBOD might it be configured RAID-1? In that case with 4 2-TB and 1 1-TB drive you would only get 4 TB capacity with the 1-TB drive not usable.
Thank you for your reply! I’m aware of Raid 1 and such, but I’ve configured it like a JBOD, and isn’t that exactly what it says it is: Just A Bunch Of Disks? So the total capacity is the sum of the capacity of each individual disk. At least, back in the days when I used JBOD for the last time it worked like that…
Hm, I formatted the JBOD-set again (as a whole) and now finder sees the full 9TB.
It looks like you had created a 9TB RAID set (disk22) but only a 4TB APFS container (disk23) was created out of the 9TB. Then, a 4TB APFS partition (disk23s1) was created in the 4TB container. This would have left 5TB for use in other containers.
Not sure if resizing a container is possible in the fly. Reformatting to utilize the entire RAID set was likely the only solution.
Yeah it looks like that indeed. Before I continue using it, I’m going to check if I add another drive to the set, that it will increase the size like it should do or that it gets f’d up again. Thank you for your reply!
Okay, so to come back to this (for in case someone ever comes across the same issue): if I added an extra disk, the usable size did not increase. I googled en searched further and it looks like it has to do with the APFS-container. In Disk Utility I didn’t see an option to increase the container size (or I have looked over it). I did find with Google a terminal command that should allocate the full usable size for the JBOD-set.
Too much of a hassle if you ask me. So what did I do? I formatted the whole thing to HFS+ so it should work now as supposed.
I read somewhere that HFS+ would stop to exist in 2050, but till then these drives will be at tech-graveyard presumably.
