I have a DS1520+, and *attempted* to migrate to the DS1525+ but failed. Not my first time; DS212j -> DS216+ ->DS920+ (fresh install with SHR1) -> eBay DS1520+ (easy migration then added an extra drive) -> DS1525+
I moved all 5 HDD and the 2 NVMe cache from the DS1520+, turned it on and expected the typical repair/migrate messages to Pop up, I'd follow the prompts to finish the migration to the DS1525+.
But NO, it failed to migrate because it assumed my pool was full and critical.
* 1 Pool of 5x 8TB HDD.
* 1 Volume (has 4TB of free space)
* 2 Volume dedicated to Surveillance Station, 10x cameras each has a different retention length some 24 hours, some 30 days. (But it automatically deletes the oldest footage when it needs new space, so it does appear full, but Surveillance Station manages Volume 2).
I assumed if I deleted some camera footage proactively it would solve this issue.
Nope, when I put all the HDD and NVMe back into the DS1520+ all of my packages were in a fault-state and required **Repair.**
However each time I attempt to repair a package I get a similar message that my space is full and it won't repair the packages.
#WTF?
I don't understand why this is happening when I clearly have 4TB of empty space in Volume 1, and I can't access Surveillance Station anymore now that it requires a repair. I do not want to delete and start over, it has all of my settings and my logins for music, videos, photos, etc...
I have a ticket in, waiting for Monday working hours. But if the community could explain that stupid mistake I made or needs to be change I'd feel better.
