I have read the following threads and this doesnt solve my issue.
This is what I have before installing new drives:
2x interal SSD for rockstor configured with mdraid.
6x 4TB “WDC WD40EFRX-68W” (RAID10, main datastore)
1x 2TB Seagate Baracuda (Unused)
They all work fine until I try and add more drives, then the UUID’s disappear and I see the error (Topic) on rockstor console.
I have tried adding;
4x 750GB Seagate Baracuda drives
or
5x 2TB Seagate Baracuda drives
I first thought the 750GB drives were bad causing this issue. but I have since valiudated this not to be true. The 2TB were only in use within another system an hour earlier and they cause the same wierd problem when added.
It seems I can only have my base configuration, plus 2x more drives, without things crapping out and mucking up the UUIDs. If I remove the drives, it returns to normal and is fine.
Could this be related to my PSU?
At boot time I know the drives will draw more current and maybe my 450W is not sufficient, and this is causing instability in the drive. What is the recommendation here?
Or there is a limitation in the number of drives that can be managed by the system.
Or there is a bug.
Or something else I have missed.
Please help.
lsblk looks like this for the, previously good 4TB drives, others are just missing.
