NetApp DS4486 - Errors in log, no temps or smart reports
live4soccer7 replied to live4soccer7's topic in General Support
I am not sure. I thought about changing to global setting, but I also have 25 or so other disks a part of the unraid array that I didn't want to lose data for. I would imagine the global setting would persist. I would like to run smart tests on all 48 disks and be able to see the temps. The smart tests for now because the unit is newer and the seller said he would replace and disks that failed the smart test. -
Help Identifying this Supermicro 24bay (cse846) backplane
live4soccer7 replied to live4soccer7's topic in Hardware
Thanks. I have compared pics and given the serial number and the build model number to supermicro and everything indicates SAS2 EL1 -
I have a scenario where I have to change from the "default" settings on the spin up and spin down settings when you click into a disk. Same things for SMART test controller. I change the settings and then once I go back into their they are set back to say "Default". I have clicked apply in that specific section the settings applies to. I have then tried clicking "done" and also just going back to the main tab. If they do persist, it is only for a few minutes/hours and then they seem to revert back to say "Default". Any ideas? Edit: I'm usually trying to change these when the array has already been started.

This: If you mix user shares and disks when moving/copying files, you can actually lose data, because Linux doesn't realize that the source path and the destination path might actually be the same file, and so tries to overwrite what it is trying to read. This is often referred to as the User Share Copy Bug. I tried it out of curiosity, pretty sure lost that data. It wasn't a ton though, so not a big deal. I've been searching the whole server for it.

Help Identifying this Supermicro 24bay (cse846) backplane

SM said it was BPN-SAS2-846EL1, which is what I was thinking. I am also trying to confirm with the seller as I really don't want a SAS1 backplane. -

Thank you. I will try to give them a call. I am trying to compare some pics online as well. -
I am buying this, but am having the seller check which backplane is installed. He does not know much about it and can't seem to locate the number of the backplane for some reason. I think he simply has no idea what/where to look. I pretty much just want to be sure it is one of the SAS2 backplane/expanders and not the BPN-SAS-846A backplane. I'm not terribly familiar with them and never had one in person, so I can't tell from the pics. This is the cable that is in the picture: https://store.supermicro.com/supermicro-internal-to-external-minisas-2-ports-low-profile-cascading-85cm-cable-cbl-0352l-lp.html

Well.... I learned the hard way that if you don't do background and your ssh loses connection then the transfer will fail. That lost about 16 hours. haha. Is there a way to check progress of the background process? I started a new one. Also, what is the behavior of "background" for copying a file if it already exists in the destination? I see that it doesn't ask you or mention it. I had too many files to manually go through, so I just copied all the original files to the destination again.

Great idea! I just did raid 5, but it is giving me some wonky numbers for free/available space. I'm not sure if it is a bug within unraid or some other issue. I have two identical raid5 setups and one says 92tb available and the other is 96. Regardless, I'm going with what you suggested on the raid0. I just did half the disks with 4 raid0 pools (6 disks a pool to keep numbers even). When I create a new share, how can I add the "pools" to the share? I just see use cache and then I can select one pool/cache, but not multiple.

They are 4TB disks. The idea is to maximize space. Each raid 5 I create, I would lose 4tb worth of space. So, when I go to the pool for the raid and click to change to raid5, it says *see help. I don't see this and there is no additional information in the wiki/manual. https://wiki.unraid.net/Manual/Storage_Management#Change_Pool_RAID_Levels In the manual it says: BTRFS supports raid0, raid1, raid10, raid5, and raid6 (but see the section below about raid5/6) I can not find this section.

A few here have been helping me with disk configuration, etc... with my new netapp ds4486. I settled on using the pool feature for the disks and splitting the 48 disks into 2 pools. I had already created a pool with about 12 disks to try and then added in the additional 12 after I had added 10tb of data or so to the pool. Now it is taking FOREVER to "balance" the raid1 with the new disks added. I realized that I actually want to do raid5 to increase the available capacity to me to the max and not be able to lose the entire array with a single disk failure. Ideally, raid0 would be best to give me the most space, but it seems I would lose the entire array if a single disk fails, which I don't want. I don't mind if I lose the data on that disk, but I don't want to lose the entire array/pool of data at once from one disk failure. To the point. Can I cancel the balance and then immediately switch it to raid5? The balance is at 43% done and it has been about 2 days?

NetApp DS4486 - Errors in log, no temps or smart reports
live4soccer7 replied to live4soccer7's topic in General Support
I've pretty much confirmed it is literally just the spin-up time of the disks. If I do a FS check on the disk when it is spun down then I will get the errors posted above. The check will fail and the disk will be spun up moments after (automatically). If I do the check again when the disk is spun up then it works perfectly and there are no errors. It is simply a timeout issue while waiting for the disk to spin up. It takes roughly 3s more to spin up than a disk not on the netapp and that difference is the problem.
