I read the warning posting that if a disk is failed and you replaced a disk in RAID 5 mode, it will delete all the data. This very concerns me, because the whole reason of buying a RAID is for reliability. and I will store all my kids pictures and video in it. So, I want to do some tests. In order to mimic the situation, I am thinking to remove a disk, format and clean it so it would be recognized as new, then see if it can recover.
However, I can’t find a eject disk button. How do I safetly eject a disk? I think there must be a way, because if I already have 4 disk and want to replace with a bigger disk, then I will have to eject it, and plug in a new one.
Yes. I thought there would be a eject button on the manager. In fact, it seems I just pull it out. But once I pull it out, the only way is to rebuild it.
In another group where I had commented about my disappointment with the ShareSpace, someone replied
Some time back it became unresponsive, logging in to its homepage there were odd lines of script, and I couldn’t see the drives. I then found I could not access the folders. After several hours to a WD tech in the USA (after the initial usual divert to that part of the world) it couldn’t be fixed. When you install drives in these, the operating system for the NAS is written across the drives. If it becomes corrupted your well and truly up the creek without a paddle. The solution was simple but very painful - remove each drive - write zeros to them and then reinstall all of them and let it rebuild (RAID 5) overnight. Luckily the TB or so of documents I bought this thing to protect were still on the machines at home.
Perhaps WD could clarify if this is correct, i.e. it is not possible to rebuild RAID5 without complete dataloss?
Thats a joke? That is why i set the system to RAID 5. Even if one drive fails no data gets lost. Thats what RAID 5 is for. When one drive fails the parity should contain all data that might be one the corrupted drive.
That means: When you remove one drive of four. Restart your system and it will still work.
You will tell that this is not the fact. That would be rediculous.
