I would like to update my server (Platform 10.0.0-1, Core 10.4.0-1, Fedora 25, HPE ProLiant MicroServer Gen8, 4 drives, Greyhole storage pooling) to version 11. Last time I made a clean install from version 9 to 10, but it was a large project for me, as I don't have experience with Linux systems.
- Briefly checking the forum, I see that there is an upgrade option, but it is not really recommended. It is advised to remove all aps, which is fine in general (DLNA, Transmission), but what to do with Greyhole and storage pooling?
- If I do a clean install (as I did last time from 9 to 10), what is the best practice with the pooled drives, shares and users? Last time it took me nearly a week to rebuild the pooled drive, setting up users and shares, and I am not sure I made it absolutely correctly. How should I safely re-build or re-use the pooled drives?
I am not an expert with Greyhole and Linux, so maybe I am not describing correctly my setup:
sda: Western Digital Red 3.5 4TB 5400rpm 64MB SATA3 (system and shares/Greyhole LZ partitiones, 65% free space)
sdb: Western Digital Red NAS 3.5 3TB 5400rpm 64MB SATA3 (non duplicated films, documents, 70% free space)
sdc: Western Digital Red NAS 3.5 2TB 5400rpm 64MB SATA3 (pooled, 15%!!! free space)
sdd: Western Digital Red NAS 3.5 2TB 5400rpm 64MB SATA3 (pooled, 15%!!! free space)
As the 2TB drives starts to be too small, I might by a new 4TB and reorganize (of course, this means clean install):
sda: Western Digital Red NAS 3.5 3TB 5400rpm 64MB SATA3 (system, shares/Greyhole LZ partitiones)
sdb: Western Digital Red NAS 3.5 2TB 5400rpm 64MB SATA3 (non duplicated films, documents)
sdc: Western Digital Red 3.5 4TB 5400rpm 64MB SATA3 (pooled)
sdd: Western Digital Red 3.5 4TB 5400rpm 64MB SATA3 (pooled)
What could be the safest way to rebuild the pools in this case? What should be the order of adding the disks, creating the users with home directories and rebuilding the pools. And how rebuilding should happen in Greyhole?
