August 3, 20178 yr With advice, this is reposted from General Support: I just got my new machine up and running this evening and was attempting to start the array. I have assigned 1 parity disk, 2 data disks (all 3TB Seagates) and 2 cache drives (500GB Samsung EVO). Each time the page refreshes it shows the error message, "Array Stopped: Missing Device node(s)". I've replugged all of my disks into the motherboard and I attempted to search the forums for this, but got 29k hits. I've attached the diagnostics, and I'm afraid I don't know what else to do at this point. If I can give more information, please let me know. Help please! server-diagnostics-20170802-2334.zip Edited August 4, 20178 yr by Meodato Adding Solved tag.
August 3, 20178 yr Author So apparently taking my two SSDs out of the Cache pool has allowed me to start the array and start parity check... I don't understand why my Samsung 850 EVOs in the cache pool would cause the failure to get nodes (they weren't being properly handled by udev/kernel?) Can anyone help me with these new findings?
August 3, 20178 yr That's strange, they are used by a lot of unRAID users, are they new or been used somewhere else before? If they aren't clean try wiping them with: blkdiscard /dev/sdX
August 3, 20178 yr Author All of my hardware is new. I have run that command against both of the SSDs, but as my array is currently computing parity I will have to wait until it is done in order to add them. I'll update this when I can stop the array. Thank you for your help this far.
August 3, 20178 yr If they're new it won't help, I'm hoping someone from LT will know what the problem is.
August 4, 20178 yr Author So parity finally finished and had to set up a new config in order to attempt to add the cache disks again. Still a no go. Instead of a green circle stating "normal operation, device active" the ssds are showing with a blue "new device" next to them. I'm still at a total loss.

August 4, 20178 yr I didn't look at your diagnostics- I had the same mode missing nodes message when I tired to put an unformatted logical drive into the cache pool in If your drives aren't formatted, try giving them a quick xfs format with the unassigned devices plugin (enable destructive mode to do so, in settings) then re-add to the pool. That's what worked for me. if you have data on them, then obviously don't format the disks unless it's easily replaceable data already.

I will try that after I get home from workSent from my XT1650 using Tapatalk
August 4, 20178 yr Since you're using a pool it would be best to just partition the devices and then let unRAID format them, to do it you can use sfdisk like so: sfdisk /dev/sdX then type in this order followed by enter in the end of each line: 64 write You'll need to do this for both cache devices to be able to start the array, then you just need to format the pool.

I'm glad you were able to understand my semi-incoherent post... I should not get on the internet until the morning caffeine kicks in...
August 4, 20178 yr Author Thank you so much. Doing the partition on the two drives allowed me to include them in the array. You have no idea how much relief such a simple thing has brought
August 20, 20178 yr Just wanted to add to this in case someone is searching. I tried to replace my WD 250gb SSD with an M.2 Samsung 500gb and got this error. Did not start up the array. Went into unattached devices settings and set to destructive mode. (in case you don't have it installed, you can install it as well without the array, I did) Formatted. Started Array. Array formatted it again and it was fine.
August 20, 20178 yr I just struggled with this issue today when I tried to replace my 515GB Samsung SSD cache with a larger 1TB Samsung SSD cache disk. I had to format the disk first. I've changed out many cache drives and this is the first time I have had any trouble. It was rather disconcerting. I ended up doing a new config and when that didn't work I formatted the SSD cache drive and it finally worked. Now I am waiting for a parity rebuild to finish. Has anyone reported this as a bug so LT can see it and address?
August 20, 20178 yr @johnnie.black tagged @limetech above about it but I have no idea if it went anywhere.
