Don't mistake my commentary as disagreement in regards to your points.But you of course do you. I don't think further discussion will lead anywhere.
I totally understand and get all of your points and I agree with them.
Unfortunately though, when the intended destination doesn't have enough free space, you have to get really creative in regards to how to go about trying to accomplish the same task/goal.
And also unlike a professional IT department which also comes with a professional IT budget, as a home lab user, I can't just willy-nilly go out and spend like $5000 on more hard drives to address the "insufficient space" problem.
So? What are you left with?
Playing musical chairs with the data where you have to leverage the free space that you DO have, so the data gets distributed across multiple servers/systems as TWO systems are being rebuilt and then I will reconfigure the TrueNAS server, bring it back up online, confirm the deployment methodology/strategy, and then push all the data that used to live on it back onto to it.
THIS is why the graphical, unstructured, multi-select was such an important and critical requirement for me (due in part because I am having to distribute the data that's being evacuated on to multiple destinations before eventually sucking it all back in together).
In regards to your question of how do you check that the operations have been completed successfully?
Luckily, I don't have very many hidden files and the ones that I do have are all system generated thumbnail database files, so if I lose those, it really isn't a problem for me.
And also being a home lab user, ACL is also not an issue because it's just me that's reading/writing data to the servers. (Single user accounts makes ACL also a non-issue.)
But again, I agree with you, that in a professional IT setting, what I am doing here wouldn't fly.
But also in a professional IT setting, I would also have a professional IT budget behind it as well, so an issue like this (running out of space and/or having to rebuild a server rarely, if ever, happens like this as well).
In a professional IT setting, the ZFS replication for building new servers and migrating data is more likely what's going to be done because for some/most companies that has a professional IT department with said professional IT budget, spending another $30k on another server is worth the $30k vs. the time and/or the problems that may arise with spending less on a less stable/less reliable solution to the same task/problem.
At home, in a home lab setting, that's entirely different.
I think that it is important, for IT professionals, to keep the idea that home lab != professional IT department in mind and a LOT of that, unfortunately, is tied to money/budgets.
(Because if I had $4k to spend on the QNAP 12-bay 2U NAS unit which uses their new QuTS OS (which has ZFS on Linux) and everything else that I have been talking about here, plus another $5k in drives, I would've been all set and good to go with a ZFS replication/data migration strategy instead. But that's just not the case here. I had to get the wife to sign off on spending $1k on eight (8) refurbished HGST 10 TB SAS 12 Gbps 7200 rpm HDDs because the SAS drives were cheaper than the SATA drives (at the same capacity, believe it or not) and it just so happens that all of my HW RAID HBAs are all LSI SAS RAID HBAs, so the system/server was able to and ready to accept SAS drives.) Like I said, with basically little to no budget appropriated for IT maintenance, the solutions that are required to solve the same problems look drastically different compared to professional IT solutions. I think that sometimes, IT professionals maybe forget that a little bit or that it's a little bit "out of sight, out of mind".)
Thank you for your help.
