RN204 How much storage should be free 4 x 1tb Raidar Report using raid 5
How much free space should this show using raid5 and 4 x 1tb drives. System shows healthy. See bottom three screen captures Raidar diagnostics reports this below. Does this report indicate onl...
I'm not sure that anything is actually wrong right now.
If you want me to take a look, you can download the full log zip file, and then put it into cloud storage (dropbox, google drive, etc). Send me a PM with a link to the full zip, making sure the link permissions allow anyone with the link to download. Don't post it publicly, as there is some privacy leakage.
Note you can't attach a zip file in the forum, so you need to provide a download link instead.
Test started but not completed by time finished composing this. May have to restart that in the morning.
Think my first use of the RN204 was on 21st 10 2023
It immediately informed it had one degraded volume on disk 4 that was noticed, bear in mind my not ever using any nas previously.
Alerts were setup that day but recall deleting bunch of stuff as got so many over period of days, below is a timeline of events still hold alert emails for.
Please bear in mind when you read them they are in the correct order they arrived in. The time never set correctly at first and had to alter the time zone, thought at first it was something to do with lack of any summer time setting, eventually switched out where it connected the time update location.
Sat 21/10/23 18.47 If you receive this message, the email alert notification is working properly.

The next day after having disc 4 drop out both days another identical disc was ordered. It then seemingly has behaved itself since then and is in disc 3 slot now (noticed it’s ATA errors so know which disc is which by that) Why later after online reading thought maybe a drive bay fault which is said to be common hence bay switch for the disc. The ATA errors have not increased and disc 3 put into slot 4 has still got zero errors for that, as too the other discs. [nb the disc which was ordered was put into my Qnap temporarily to get that setup after the lack of apps on here and the cumbersome uploads to it. RAIDar makes doing that so much quicker, glad managed to find that and install it on 31/10/23.
Not been using it the last week or so for 2 reasons, getting the Qnap setup and to see if powering this RN204 off and unplugging it makes it lose the raid array or not over extended periods of time. Do not wish to waste money powering a device not being used.
On arrival all discs were clean formatted and no raid setup.
Do not understand why all the volumes show the green block indicating that they are “Spare” and not just all blue blocks as per the “Raid” square.
RAIDar was downloaded and installed 31/10/23.
Disc 1
Disc 2
Disc 3
This originally was disc 4 in the array when it arrived.
The ATA error count has not increased at all.
Disc 4
This originally was disc 3 in the array when it arrived.
"The tiny little green square does mimick the power LED. A spare disk would be all green, not blue. "
Apologies for my ignorance but do not understand what you mean here. That would indicate all 4 discs are "Spare", which not understanding that meaning of "Spare". With the array at first only showing 3 drives for awhile, and the 4th Degraded thought it indicated 4th drive was "Spare" as it not linked to the raid array. Also why thought all 4 should now show blue square to indicate the raid array is working.

Sorry, no. Your NAS does claim to have four active RAID members, thus the complete disk is shown in blue.
A spare disk would be black (not green as I wrote before), the label showing the green square is equally wrong - it should be dark grey or black instead.
The little green filed does mimic the HDD LED (e.g. green for powered and workable).
What I wanted you to do is login using ssh as root (same password you set for admin) to your NAS, and run the command as shown, and copy-paste the output to the thread. Needless to say, ssh must be enabled to allow this.
cat /proc/mdstat

Tried to, think it is something to do with broadband provider settings affecting it working.
The explanation for the disks is appreciated, now do understand what it means. Had thought the small green square the indicator, duh!

Thanks but as you say, all seems to be working fine. The size available question stemmed from the 4th disc dropping out of the array the first couple of days [why an identical disc was purchased to the ones in it], it made me wonder if there should be more space available and expected to see a shade over 3Tb.
Thanks also for getting the posts visible, wondered if had been banned for my stupidity with the questions 😉
OK, The indicator square is now understood after reading again.
Green [as it is] - showing it is healthy,
Yellow for - The volume is degraded and finally
Red for - The volume is bad or faulty.
Disc test was run today and after a couple of hours went out to get stuff from shops, returned, still running, but in honesty no idea if it was even running so, attempted to start it again, got this
Much later noticed test had finished, so have following screens. Nothing really indicates anything not working correctly though as far as able see
