Re: Data integrity concerns TRAID

I'm actually fairly convinced it was a legitimate failure. But the lack of logging is the serious issue. In the UI it is never even presented as a failure. The array simply remains in a degrade state, after a submitting the dialog. No % recovery steps and then error. No message the drive cannot be i...

Re: Data integrity concerns TRAID

RAID 101 (1+0+1) I do no know what I was thinking 101? It would be a modified 10. First reserve enough space on every drive to store the partition table/datamap. The partition the largest drive into sizes of the smaller drive. RAID 1 the partiontions with the drive. RAID 0 all the RAID 1's. If any ...

Re: Data integrity concerns TRAID

It is not obvious to me the 750 GB disk is at fault. I formatted as a single volume multiple times and ran the short smart test. And don't get me wrong these are the types of testing where I expect failures. Drives manufactured as old as 2007. It is more a test does the NAS tell me why it failed. Is...

Re: Data integrity concerns TRAID

Admittedly I am doing things like using RAID0 as a generic description of an operation rather than the actual formal definition. If it like using the word aspirin as a generic name for pain medication. The documentation just says traid first combines the smaller drives. The md logging makes it appea...

Re: Data integrity concerns TRAID

You should stop using the word "actual". I do not think it means what you think it means. My only speculation is how the superblocks are cleared and what I might have been able to do to recover. How Terramaster constructs the arrays is described in the terramaster documentation. If that is...

Re: Raid of One 18TB & One 12TB, Accessing the Remaining Space of the 18TB

Possibly you could do it if you are willing to drop to the command line. You would basically need to create logical volume that pointed to the unused space. I personally would not risk my data to do so.

Data integrity concerns TRAID

I just purchased a F4-423 and I have been testing with TOS 5, TOS 6, and Unraid. Overall, I think TOS 6 best fits my desired usage. I like the fact pretty much all the drive maintenance can be done on a live system. And I really don''t have need of the extensive pool of docker containers available f...
