I have been playing around with Rockstor a lot these last days. This has given me some questions. Some about functionality, and some thats just plain curiosity.
First: What does the three colours (white, blue, orange) that is shown during boot signify? I know its probably a stupid question, but they must mean something besides for having something to look at during boot?
Got my PCIE to mSATA card today (still waiting for the mSATA drive). It works perfectly, and I actually use its SATA port for the boot drive. It has given me the opportunity to work with a setup much like the one I’m planing.
So right now I have 8 disks hooked up to the computer. 6 through the mainboards SATA, one through the SATA port on the mSATA card, and lastly one through an USB adapter.
It all works fine, I now have 7 disks of varying sizes available for the pool.
My plan was to expand the current pool from 4 to 7 disks, and at the same time move from RAID5 to RAID6. But the interface wouldnt allow me to change RAID level. Is this something that will be changed? I know RAID56 is very new to BTRFS (and Rockstor)
Instead I have just made a RAID5 pool from the seven disks. It worked, and is doing an automatic balancing right now.
I’m rather impressed with BTRFS’s ability to use disks of different sizes, and maintain redundancy.
I guess a cmd line command could be used to change the RAID level?
ECC ram needed? Current RAM is non ECC, how great is the chance of things going wrong, and wouldnt BTRFS’s error correction systems help? Given off-course that the RAM otherwise works OK. The system will primarily be used for media storage, very few really critical data.
Another thing, completely unrelated.
When I use top at the command line to see some info on processes and RAM and so on, it reports an uptime in the upper left hand corner. The web-interface allways shows an uptime off 1 hour more. I think the one “top” is showing is the correct one. Is this a small bug, perhaps caused by daylight savings time?
