Re: RAID Group 1 "Not active"
next step would be to peek at the config file...did you open a ticket with qnap yet ?

Re: RAID Group 1 "Not active"
Hi,
I got a similar issue as reported by others in this thread.
I had a failed disk, and RAID Group 1 turned to Not Active.
I've put a new disk in, which the GUI sees correctly. All 4 disks are green, but the recover RAID Group is failing.
When running md_Checker, it seems I got disk #2(3rd slot disk that failed and got replaced) as missing.
It also seems that #3 is slightly out of sync by a few minutes.
Recommendation on what command to do next??
thanks!

Re: RAID Group 1 "Not active"
Backup available?
If so, dont hesitate, rebuild raid and restore.With two disks failed (one missing, one seems out of sync) raid5 is gone usually.

Re: RAID Group 1 "Not active"
Unfortunately not.
Even if mdadm assemble will succeed, you need to reconstruct the LVM information.
Best is may be to contact QNAP support.

Re: RAID Group 1 "Not active"
Hi - Wondering if anyone can help diagnose what I'm seeing w/ my raid, and how I might be able to get it sorted. What's weird is md_checker shows 2 devices missing, but the qnap interface shows disk2 missing despite it being physically there. Previously they were scanned as fine / ok.
Thanks

Re: RAID Group 1 "Not active"
Hello! Did you find the solution?
I have the same problem with very small difference.
I have "Status: OFFLINE" and "Chunk Size : 64K"

These commands can be extremely destructive if you have now idea what you are doing, so best to open a support ticket if you already have to ask what and where SSH access it.
