ReadyNas 10200 - replacing bad disk on a RAID 1 configuration?
Hello to everyone, I'm having some problems on my ReadyNas 10200, already configurated in Raid1 with a Single HDD a couple of years ago, after added the second HDD a few days ago. Before adding the...
I don't know why you opened a new topic for what you already started in another. The progression you saw, as was explained in the other thread, is perfectly normal, at least up until the completion of the sync. The wording of the messages may make it sound otherwise, but it's not an indication of anything amiss.
You went from a healthy, intentionally non-redundant volume to a degraded (not redundant) volume that is intended to be redundant. The NAS simply changed the definition of exactly the same redundancy state based on the desired final condition and then started the sync process to establish the redundancy.
The only issue here is that the RAID sync did not complete properly. It has absolutely nothing to do with the process you followed or the messages you saw along the way, which were all quite normal. One possibility is that the new drive is faulty. The old one may have developed a problem duing the sync, but I think you'd see much worse symptoms (a dead volume) if that were the case.
Powering down the NAS and testing each drive using a PC and vendor tools is a good next step. I actually always do that before I ever add a drive to an array. There may also be clues in the downloadable log .zip file.
good evening Sandshark,
when you talked about the downloadable zip file you mean the zip registry file which I could download from the registry tab or something else?....If you're talking about it, then I downloaded it today, but there's a lot of files inside and I can't understand what I need to search and check...inside the zip also there's a "volume" txt file, I opened it...there's many infos about the two disks, also about the disks' sectors but It seems to be alright...
Maybe is there any particular txt file that i could cut and copy here to let you check if there is something wrong?... maybe you might be able to find the problem to solve right away..............

Please cut/paste mdstat.log into a reply, and then we can go from there. The "insert code" </> tool in the toolbar is useful for that.
It would also be useful to power down the NAS, and test drive 2 with WD's lifeguard program in a PC.
