File server build

[Red Squirrel]

Was going to wait till I'm done with my basement renos (dust) before I rack my server, but I was too eager to do it so it's done and I can clear my office workbench, so I just did that now.




Yeah I know, it's a MESS behind there, but part of my goal with the basement renos is to build some type of cable management system for the server rack, with some PDUs. So for now I'm not bothering with any cable management as I will be completely redoing everything from scratch and labelling as I go. Probably a 1 day job right there.



ICMP reply and alarm clear! Helps if I turn the port up and put it in the right vlan. 😛



Which drive do I format first! Actually it's more like: which one is which, so I can reconstruct the old raid array on the SAN. 😛

Also, the bottom two enclosures are currently unusable, because I went and used a couple drives as regular sata drives, and that broke the firmware lock on them (was not aware till after) so they no longer work in the SAN. I have to figure out which drives these are and decommission them. The reason I built this server instead of just using this SAN is because of this. I can't just put any sata drive in there. So I will use it as extended storage since I have it, but wont rely on it for actual productivity stuff. Will be mostly for backups/archiving. I don't have enough UPS capacity to protect it, so I rarely turn it on.

I wont be leaving this on till I'm done the renovations though, since it's brand new and all clean I want to keep it that way. When the server room is done it will have proper hvac with air filtration.

Love Linux mdraid. I "recovered" the raid that was on the old SAN. It was created on a completely different machine. I was able to just do --assemble --scan so I did not have to guess which device is which. It seems when I boot up and the enclosures are on it pushes the local disks up so you can't go by the drive letters.

The small array is the local one. It's more experimental. I have 1 drive to RMA then I will probably just make that one a raid 10.
