Disk failure during volume resent / can I stop resync ?
I have a Pro Pioneer Edition 6-bay running OS6.6. This NAS acts as a backup for some other NAS-es. The available space on the Pro was running low, so I decided to expand it with a HDD that I had used before. I formatted the "new" disk and inserted it in the Pro. Volume expansion stared as expected.
On the admin page, the expected resync time is very very high, in the order of 400hours. Also, there was an error message regarding the health of the newly added disk.
What should I do:
Can I stop the resync? How?
Should I remove the newly added disk? Will this affect the volume, in other words, will the NAS still be avaiulable?
Should I just let the resync run until it finishes? And then maybe replace the disk that is giving errors?
Thanks for looking and answering :-)
Cheers,

That was the error message? Perhaps check the current smart stats on the "new" disk.
If the disk is really failing, the resync won't complete anyway. Since it is a backup, restoring the data shouldn't be a huge concern. So if the disk is struggling, perhaps pull it.
Assuming single redundancy, the volume would be degraded. So you'd want to get a healthy disk that matches the size of the "new" one.
Error message is:
Detected high command timeouts: […]. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.
So, you recommend that I just pull the faulty disk and change it for a new healthy one?

If the timeout count is continuing to rise, I would do that, yes.
Of course there always is some risk when the volume isn't redundant, but I don't think changing out the disk will make that risk worse.
