I have been having issues with my FileServer recently.
I just rebuilt it since I couldn't get any guidance on the issue. Unfortunatley, its resyncing my array again.
Seeing how this has been done multiple time in the last few days, I'm fairly confident that its "in sync".
I have a few questions to that regard.
- When it resync's what is happening, is it just doing read operations on every piece of data? I feel i'm really abusing my HDD's at the moment
- Can I cancel resync? (I still want to be able to use the MDADM Though!)
- So Can I force it to "clean" state and remount?
- Is resync automatic when you mount a new MDADM (This is a new VM), or is there an error in the metadata that is forcing a resync and I NEED to let it finish. (It takes about 24 Hours and my server is extremely slow during that time)
Update: There are 4x 5tb HDDs in raid5 passed through via mapped raw lun to a VM guest which then exports nfs and smb.
This question is mostly about if the commands i want exist for mdadm and what sync does.
