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.

This question isn't related to disk health.
4x1TB RAID5 yields a 3 TB volume. However, the NAS reports total space in TiB (1024*1024*1024*1024 bytes), not TB (1000*1000*1000*1000). 3 TB is the same as 2.72 TB. That is about what your volume shows - 2.54 TiB of free space, plus about another 0.18 TiB for the data + snapshots.

The fact that one disk is not in the array is particularly concerning. The volume should be reported as degraded - is that currently the case? (it clearly wasn't when you took your screenshots).
A single reallocated sector isn't a huge issue, and neither are 2 command timeouts. Worth watching, to see if the numbers increase.
If you don't have a backup of your files, you should put a backup plan in place. RAID is not enough to keep data safe.
Once the data is safe, I suggest running the disk test from the volume settings wheel. There will be a log entry when it completes. Then look at the stats again.
Meant to include these screens from RAIDar too. Note the lower one reads exactly the same today as yesterday despite doing a rescan.
What shows (from the NAS shell) /proc/mdstat ?
root@RNxxxx:~# cat /proc/mdstat

My lack of knowledge using nas shell means could not get that to work despite setting it to SSH following netgear guides [since switched off, only open moments].
Does the antivirus still work? Always appears to be updating.
Completed a boot test on the discs, it shows this from logs, [personal info removed]
