ReadyNAS Pro6 fails to boot (at 98%, "Management service is offline") after hard shutdown
My ReadyNAS Pro 6 is using OS 6.10.10 - and had no issues in the past. Recently, I had to replace a disk (because it started to show problems): 3 TB -> 6 TB (WD). Replacing was no issue, syncing to...

I've only removed drive #1 (troubled 3TB) first and replaced it with a new 6 TB drive; then powered up. That would resulted in a sycn (took about 5h).
Only afterwards (and after having shutdown the Pro 6) I've added the additional 6 TB drive. That 2nd sync did not succeed.
The second drive would have needed TWO syncs one for the original 3 TB partition, and then a second sync to expand using the extra capacity. If the first sync succeeded, then it would be better to attempt to mount the volume with that disk install. It would need to be inserted with the NAS powered down though.
Without logs, we don't know what we are dealing with. It would be useful to see the disk partitioning, so if you could post the output of lsblk, that would be helpful.

Yes, I do have (weekly) backups but I'd like to avoid a factory reset.
While we might be able to get the volume mounted, there will be some corruption. The best path is to do the reset and restore the files from backup. In addition to getting you a clean system, it could well be the fastest path.

Is the volume mounted? /home is a mount point for /data/home - so if the volume isn't there, /home will also be empty.
Do you have a backup of the files?

Hmm - just checked: I've only a pretty old manual backup (2020) and I should have also the incremental backup (using the scheduled backup job of the ReadyNAS Pro 6) but I've not confirmed whether that's really readable.
So, I'd really like to mount /data manually so see what's still there.
Should I insert all 3 disks (incl. the one which is not entirely synched) or should I only use the 2 disks which were previously used successfully?

I've done so all the time (3 disks).
How to continue? Is there a chance to mount /data manually?
And how to verify that my external USB drive did actually contain the backup data?My ReadyNAS Pro 6 manages to boot up to 99%, then it remains there for a while and finally it fails to respond even to pings, so I have to perform a hard shutdown.
Also interesting: I'm still able to access my own home share - but actually that cannot be (since /home is empty). So, I assume that there's some buffering.
