Write Cache should be enabled for better results. or maybe even partition 1 - reiserfs ( for use as a cache drive? ) partition 2 - FAT(VFAT) syslinux /boot Unraid supports the use of encrypted drives in both the cache and the array. Theme . If this happens again then it’s a sign that the drive is on its way out the door. So i added the new nvme drive to my cache pool and realised it was set to raid1 when i did that. Poked around dmesg and the drive logs and see the below: sadly the trick with the part_table copying worked on just 2 HDDs - with the others UD shows a partition but is not able to check them - very strange. Mover doesn't help, nothing helps! I had to accept the tiny text saying that starting it would remove the missing cache drive. The 8TB data drive: "Unmountable: Unsupported partition layout" The NVME cache drive "Unsupported or no file system". It turns out that none of the user shares are accessible and so the VM manager will not operate and allow VM's to start. lol Was this a disk in the parity array, was it part of a cache pool, was it the only cache drive, or was it unassigned? You should have asked for help before trying to work with the disk outside of Unraid. 2 Beta 18, unRAID started support for NVMe devices as cache/pool-disk. My configuration options seem to be: It seems to be signalling itself whenever it sees a change in the mounted partitions table, or when it times out at 3 sec accessing disk info. Asking for cache data failed Jun 24 08:42:47 Tower kernel: sd 1:0:0:0: [sda] Assuming drive cache: write through Jun 24 08:42: Hi Team, I tried migrating my Unraid server unsuccessfully to a different piece of tin and after wrestling with the new machine, decided to revert everything back to where it originally came from. I rebooted to get the second drive detected again and I the only way to expand ZFS pools is by doubling the drives you already have in a single go. If it’s worth it is entirely depend on many other factors. 0 introduced a 1MiB Partition alignment in an attempt to fix the excessive docker writes issue. Still full, still locked. But Unraid 6. 9. Anything like a super micro, proliant, or a power edge. It give the flexibility to add, remove or even upgrade : All of the contents of the old drive will be copied onto the new drive, making it an exact replacement, except possibly with more capacity than the old drive. when i start the array Any benefits of using NVME drive for cache (no VM's there), like faster data transfer to the array for example might be worth looking at some second hand enterprise hardware with more expandability if you decide to upgrade your unraid hardware. if that problem happens again, and I have 2 cache drives in a parity type of arrangement, however unraid actually manages that, having them in party/replicated wouldn't help because the bad ram will affect both? doing that particular setup will Btw, I do also like the idea to be able to remove a drive while keeping parity protection, I did it once last year for testing by manually zeroing a drive with dd, then used "New Config" and "Parity is already valid" options, it worked fine, but there are surely risks while doing it manually you mistake a drive number or even while reassigning Yes, it's btrfs. Then let the magic happen. 3) I should have kept track of which shares were configured for Cache, Array, and Mover I am buying 2 because I believe I have to increase the size of my Cache drive to match the largest drive in the array. so we are working on the assumption that the faulty ram module caused the corruption. Anytime I tried to format and partition cache to xfs, it would revert back to btrfs. 1. If you just put it on your cache disk, unRAID has already taken care of all that. if you use btrfs (the unraid default) you can just slap in a second drive and it will raid 1 it automagically. What about 1 file that is in use? (on the cache drive) If you do it as a separate disk you will have to partition, format, mount, unmount yourself. So a couple days ago I encountered fs corruption on my cache drive. Ah that totally makes sense. Stop Plex Container. then I highly recommend you shut down the Unraid server, remove the drives, remove the partitions using a Windows system I have already got 2 Samsung 960 EVO m. It looked like it was plotting onto a slow array drive instead of my ssd cache drive where I'd intended it to go. 2 has a bug preventing the format of drives above 2TB. Drive encryption is one of Unraid's many good features. (eg: Plex should have all metadata, If you do not have a cache drive, will store on the array, and if a cache becomes available the data will move to the cache. but you do need to have more than 1 drive to get it started. For those of you using the Cache Dirs plugin, you need to specify folders to be included so UD mounted disks and Hey fellow unraiders, I'm new to unraid and in need of a bit of guidance on how cache disks work in unraid and how best to utilize them. I find that with UnRaid menu managing the array to be relatively straight forward not requiring me to do command line instructions. The NVMe drive is partitioned with the primary partition as the cache (XFS) and the second partition as a VM disk. on start, it waits 300s and the attaches the L2ARC-partitions to all my ZFS-disks. free), so its an accurate reflection of the space that isn't available in the cache partition, rather than reporting the space used on the cache partition like'df' would this is actually what I think you want to know from the webgui, and was a pleasant surprise, bearing in mind this is Just bought a PCI-E card from Amazon, attached an SSD to it, but when trying to add it to unraid, it is coming up "Unsupported partition layout". The drive had at least two partions on it, one of which was the windows recovery section. partition 1 - FAT(VFAT) syslinux /boot partition. I didn't read any wiki before doing this test and so I noticed that the cache pool concept was applied. 4] Adding a cache (L2ARC) to a ZFS-Disk in the unRAID-Array makes the disk unmountable on Array-Startup. I wanted to try this solution, but the Beta Preclear plugin doens't seem to exist any more. this is also one of the main reasons why ZFS is dumb in home servers. /dev/sdX1). Adding a 6TB drive as the Cache. I setup a cache drive using a 500gb and 1tb SSD. Find drive label - The following command will list all detected hard disks:. i should have did a little more research in the unraid gui. Unraid IS NOT RAID, but just like RAID, Unraid parity allows you to calculate the data for a missing disk from all the other disks, so a failed disk can be rebuilt. Just setup different user shares for different purposes, and configure each to use cache as appropriate for your use. Anyway, after rebooting (not detecting the second cache drive) it started the array, without the second cache drive. x has cache drive pooling setup in the webgui, but I've not been able to see how it works in the latest iteration. switch all the shares that you wish to store on the cache drive to Prefer, before installing the drive (s). When I run several commands from PUTTY it even tells me my VM is 322GB and appdata is 1GB. 9 releases, so that is what your shares are likely configured to use and any path to cache you might have specified explicitly. Hey Guys, First of all, I know that you're all very busy on getting version 6. My primary concern is speed of the server as a whole when doing file transfers. So, my build: I have unraid setup with 5 data drives, 1 Parity drive, 2 cache drives (2x 250GB SSDs in btrfs, giving me 250GB space), and some other drives in Unassigned devices. What i'm trying to work out is the best cache settings to use, whilst also minimizing HDD drive-spin up, and SSD write usage too (obviously depends on the apps In share settings I set "Use cache (for new files/directories):" to Yes/Preferred (forgot which one, I keep changing to test them out). I've read several posts in the forum about how unRaid 6. To assign devices tothe array and/or cache, first login to the server's webGui. dmesg(1) may have more information after failed mount system call. I made a foolish mistake this morning before work. Reboot and the same issue. 83 stating the cache drive was almost out of space. Then used fdisk to create a new partition table on each drive. That button should not show until all partitions are unmounted. To get a little more technical, we don't actually store data on drives, we store it in file systems on partitions of those drives. I stopped the running command and redid the command above as venv/bin/chia plots create -b 5000 -r 2 -n 1 -t But now I see that the drives are showing up with partition formats of "MBR: 1MiB-aligned" rather than GPT. Partition info is outside parity, so if you rebuild one disk at a time Unraid should recreate the partitions, to confirm, stop the array, unassign one of the unmountable disks, start the array, check that the emulated disk mounts correctly and data looks OK, also good to check filesystem, if all is well rebuild, you can rebuild on top of the The major benefit for most people is simply transferring data to a cache drive is faster than directly to an array drive, maybe twice as fast, but for me, I’m rarely transferring data from one computer to UnRaid, usually just direct downloading and I don’t care much If it takes a few minutes more for a new download to be transferred to my This was done for safety and yes you have to remove the partitions before a disk can be precleared. fdisk Recently (within the past hour or so), my Unraid server went unresponsive. zip. For those of you using the Cache Dirs plugin, you need to specify folders to be included so UD mounted disks and At the bottom of the main GUI there should be a checkbox and dialog to initiate Unraid's formatting of any unformatted disks in the array. Now in the GUI, my drives are shown as only: Cache (sdb) Cache 2 (sdc) So where do I find the partition number (if there is any)? or do I just put: /dev/sdb and /dev/ sdc or /dev/ sdb1 and /dev/ sdc1 edit: Also, I ran the command: If the original cache is xfs, you have to clear the drive, format the drive and create a new cache pool. You can have a cache pool, which is where you have two or more same size drives mirroring each other (the same data on both). " Seems like what it's actually saying is that only the I have 7 Unassigned Drives connected via the HBA. size - sdX1. New - DARK - What happened in my case is that I wanted to mount a disk to make it visible to the system and put it as second cache drive. Start the Array, the cache pool drives should show as "unmountable". you get disregard my question. Wait until it mirrors all the data to the new drive. uwyj kaiaxxd jtswkc vrozh gpbtadm xov xnjssx lgcf sppo oze
