I've been having issues trying to preclear multiple drives at once. Couple nights ago, I managed to successfully preclear 12 drives with 1 cycle. Once that finished, I started another 11 drives. During the Post read phase, one drive timed out and the raid controller failed it. PreClear also failed the rest of the drives due to the one drive timing out. I'm still not sure if preclear caused it or the raid controller. But the drive appears fine. So in order to complete the cycle on all the drives that stopped/failed. I used the verify option thinking, it was going to do a pre-read and post read. But after the pre read phase, it started zero'ing the drives again, which is not what I wanted. This plugin is not stable enough for me to clear a bunch of drives at once. An enhancement request I have, is to be able to select multiple drives at once to pre-clear. It takes me close to 10mins to click through 24 drives to select the options and start the pre-clear. Not to mention the massive gui slowdown/stall the more drives you pre-clear at once.

So I attempted to preclear 24 HGST 4TB SAS drives at once. One thing I noticed during the zero'ing phase, the web gui hangs. I thought unraid crashed and rebooted. I started zero'ing the drives after the reboot. I noticed after about 8 drives, the web gui starts to get slower and slower till it's unresponsive. I decided to do 12 drives at once instead of 24. System Specs: i7-5820k 64gb ram Areca 1882ix-16 SuperMicro CSE-846 used as HDD enclosure. I wanted to run a few cycles through these drives, because these are datacenter pulls and I want to be sure these drives are good before putting data on them. Also, is there any way to just opt in or out when sending usage reports instead of it constantly popping up a dialog asking to send the usage reports? When pre-clearing 24 drives the usage report pop up gets quite annoying.

Thanks sureguy, I'll give that a try tonight when they finish clearing. When I unassign the parity drive, can I just re-assign it to the new cleared drive on another slot/port? Or am I combining too many steps at once? Thanks

I just got two 3tb Reds and I want to make sure I add them to the array safely. I'm running v5.0 rc8a They're currently pre-clearing and I don't want to remove the drives after they're done. So first thing I want to do is assign my current parity drive slot to the new 3tb slot. Is it as simple as removing the parity drive, boot it up with the array stopped, then re-assigning the parity drive slot to the new 3tb? Or, should I just play it safe and physically replace my current 1.5tb parity drive with the 3tb, rebuild the parity, then move the slots? I just wanted to be safe and efficient when doing this and double check my steps. Thanks for your time
