In this video, I test some drives, and find some that will do very well in the DIY DAS. I finally managed to get the DAS up to the 100TB with 10x 10TB drives,, plus the 4 smaller drives.

I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.

Great as always. If you setup a TrueNAS at both locations you can setup TailScale and replication between the 2 servers - no more travelling hard drives for you

Actually you can get CMR (non-SMR) drives larger than 2.4TB (e.g. Seagate Iron Wolf) but 2.4TB is afaik the current limit of 10K RPM drives

I guess what you mean with "TrueNAS is not as flexible as Synology" is that you cannot easily add additional drives to a pool. That is correct, but not a problem of TrueNAS, but a problem of ZFS. Actually not a problem, but something that simply comes as a downside with the huge benefits that ZFS otherwise offers. Having that said, you can obviously add drives to a pool by just adding another pool. This other pool obviously should have about the same amount of drives as the first one, otherwise they can negatively influence their performance. Also, they must be the same type of pool, meaning you cannot combine a Z1 and a Z2 pool. This is why I typically add them as bundles of 4 in Z1. So yes, Synology and their hybrid raid approach is more flexible in those regards, but obviously it does not provide all the counter measures against bit-rot and so on that ZFS provides by default. That is specifically important when talking about long time back-up storage.
@MyPlayHouse
@MyPlayHouse 2 месяца назад
Well I have 25 year old Raid controllers that can add a drive to an array. I was really disappointed, when I found out that ZFS can't do that. Software,, you can do anything! but not that? If I had put 40TB of data on my DAS, and wanted to expand it on ZFS to 70TB,, I would have to copy everything off, and remake it.
@Burnman83
@Burnman83 2 месяца назад
@@MyPlayHouse Yes, again, these old controllers can do that, because they are not locked by this additional functionality that makes ZFS way better than hardware raid or simple software raid solutions such as the one used by Synology, but ZFS therefore comes with that single downside only. Having said that, you can OF COURSE, as I described above, add drives to your liking to existing pools WITHOUT copying data off of it, creating new and copying it back up: You simply add the drives to the system, then click storage (this might be a bit different as I am using TrueNAS Scale, but the functions stay the same) and scroll to the pool you want to expand, click "Manage Disks", select the new disks and add them to the pool you want to expand. Then you go back to Storage and click "Manage Devices". In there you click "Add VDEV" in which you select the new disks and add them to a new VDEV that is the same type as the existing VDEV you want to expand and click enter. TADA! If the available storage on the pool is not automatically updated you just click "Expand" and confirm you want to expand the pool size to all that is available. Done. (No waiting time, no risk of losing a disk during the sync process, no nothing) If your original VDEV is e.g. a RaidZ1 with 5 disks and the additional VDEV is a RaidZ1 with only 3 disks, he will warn you that this change will come at the cost of performance, because he will obviously leverage what goes where as per available free disk space, and if it goes to the VDEV with 3 disks, this will be slower than the other one, but he will still let you add it. I really don't see a problem there. If you want the filesystem to tolerate not replacing, but adding or removing disks from an existing VDEV, you have to live with these crappy old "Raid functionalities" that your raid controllers give you that are "hardware and problem unaware". Namely, if you run a raid 5 on your hardware raid controller and a disk dies, he will be able to reconstruct the data from the existing disks. If however the disks are all healthy, but one single bit is flipped somewhere and he realizes that during a scrub, he will not be able to correct the error, because he does not know on which disk the error happened. If things go wrong, you might lose files or even an entire array due to that exact problem. This and a lot more is absolutely no topic for ZFS, which has "multiple dimensions" of redundancy built in. Obviously, due to that huge gain in data protection, you lose the ability to add single disks, but can only add them as part of a new VDEV, which is a small price if you ask me =)

Name them with the last 4 or 5 numbers of the serial number bay device numbers might not always match on the number in truenas, scale and core also displays them differently like sda and da1 on scale my boot drive seems to move between last letter and first letter sda and sdh at boot time, core seems to stay as da1 and 2 After using scale for a bit I don't like that it lacks any io relating to latency (just has busy and rw speed, temperature) I am also starting to appreciate SAS drives especially HP and Dell (I haven't tried any others yet to see if they do a background drive scan every 24 hours or at power up, like my dell Toshiba 600gb drives do) If you wanting to pre test a drive use clean all or zero fill in truenas, this writes Zeros from Start to end to makes sure 99.99% of the drive is working (obviously this is time consuming) if your using sata hdds recommend scheduling a monthly smart extended/long scan, if your using sas this isn't usually needed as they run there own backgrounds and it's does slow down the whole array (you can see the progress/status of scans under smartctl -x /dev/ usually you do -a but the background section isn't shown when using -a) Also branded (dell/hp) sas drives usually have drive write cache off by default (as it's expected to be used under hardware raid) if you pass -s wcache,on (you can save this on each drive tab in truenas under smart options) this can significantly incresses write performance (if this a sata drive drive write cache is usually default on)

something to note, some of those HGST / Hitatchi SAS drives requires Read and Write cache to be enabled. on Some HGST/ Hitachi Drives Write Cache is disabled. I would verify this under smartmontools on Linux, Install smartmontools then run smartctl -x /dev/sda. This will tell you everything about the drive. I have some 2TB and 4TB Hitatchi Drives with the same problem where the drive would perform well then just drop in performance this can be due to the write cache being exhausted, Thought I'd mention this.

Hello. Thank you for the videos, and sorry for replying a little bit late. 100TB is a lot for such a tiny PC. Why such non-conventional config? If you need to move these 100TB over 1Gb/s Ethernet, it would take more than 20 days if not interrupted. Furtheremore, the HBA card is probably limited to PCIe 2.0 x1 (~5Gbps). "x1" because of the cheap PCIe expander cable that you are using. If Truenas needs to rebuild a broken disk, it will be very very slow due to that limitation. And the CPU, a Pentium G3240T is also very slow.

If you use Tc it creates Checksums as it reads and writes then verifies after write that it hasn't changed You can also use tc to create the md5 sum files as well (so if you have static folders you can create hash file for the whole folder).
