(Ouch, I did the command while my array was already started in Normal mode) However, after the command, I stopped the array and restarted it in Normal mode, and now I see the drive connected to the pool. I see some standard folders and files, and the Lost+Found folder with (empty) folders and some file named as random numbers. So, now I have two remaining doubts: 1) Is there still the chance I totally lost some file? I suppose there's no easy way to understand it. 2) Those Lost+Found files, should I simply try to move them to another folder, then, try to randomly apply a file extension hoping that they will be usable again? EDIT: about this point I found there's a linux command that I can launch in the folder: file * EDIT: marked the topic as Solved. However, if you have suggestions about those two points, I'm listening.

Ok, the command ended. Now what? In Main, the drive is still shown as unmountable. Should I stop the array and start it again? Or, is the drive still unmountable even from now on, so I need a way to manually mount it, check the files, then at the end blank it and re-add it to the pool as a blank drive?

Hi! I try to keep this as short as possible. In the past I had problems with drives (maybe the controller, mabye the wire, maybe the whole hardware not high-level - more a noob-lab Frankestein...), however I simply removed the bad drive (or blanked it) then re-attached, and the whole thing come alive again, after the usual parity rebuilt. I never lost anything, and I usually could have used the Unraid server in the meantime. This time probably I did a mess, so I'm here simply to understand if I can recover the files (I have a manual backup for the important things, just not so recent). In short: even this time I had a drive with the "x" in Main. I removed it and I substitute it with a used Western Digital I had here, unused. The last thing I saw was the usual parity rebuilding. Today I see that the WD drive shows in Main as partially full (as the old one was), but the file in it are "gone" After a reboot I get "Unmountable: wrong or no file system" on that drive. From my totally noob point of view, I suppose that the parity rebuilding went bad, so the system initially thought that all was good instead. Now the question is: may I try to access to the "unmountable" HDD, hoping for recovering what I can? With the started array I tried to do a xfs_repair /dev/md4p1, but I got: Phase 1 - find and verify superblock... - reporting progress in intervals of 15 minutes Phase 2 - using internal log - zero log... ERROR: The filesystem has valuable metadata changes in a log which needs to be replayed. Mount the filesystem to replay the log, and unmount it before re-running xfs_repair. If the filesystem is a snapshot of a mounted filesystem, you may need to give mount the nouuid option. If you are unable to mount the filesystem, then use the -L option to destroy the log and attempt a repair. Note that destroying the log may cause corruption -- please attempt a mount of the filesystem before doing this. I read that I could do the same command with a -L in addition, to discard the journal and trying again, but I'm really scared to do that, and I don't know if doing it could impact on the rest of the Unraid. I'm not desperate, I have an (old...) backup, so I'll probably lose only the last month, not so critical, data, however I'm not sure what those data are, so even a file list could be useful to understand what I'm really losing. Any suggestion is really welcome. Thanks in advance. PS: I had the chance to copy this part of the Log before the reboot: Jun 2 04:59:12 nastower kernel: Call Trace: Jun 2 04:59:24 nastower kernel: XFS (md4p1): Internal error !(flags & XFS_DABUF_MAP_HOLE_OK) at line 2751 of file fs/xfs/libxfs/xfs_da_btree.c.

Here I am, just to throw a Thank You. I'm almost a noob user, needing a NAS at home, capable of putting just a couple of ccommands in the Terminal or following a tutorial on YouTube. I got Unraid only for a reason: no worries about HDD dimensions and combinations, no worries for the PC hardware. I used it as a sort of secondary NAS, then I convinced to keep it as primary. I had an extra old Intel i3 with 8GB DDR3 RAM and an Asus motherboard with 6 SATA. I decided to do a sort of upgrade, with limited budget. I bought an used Ryzen 7 3700X, a cheap chinese motherboard, a cheap M.2 6x SATA controller, and I recovered some DDR4 RAM I had in a drawer... I moved all the HDDs, I moved the USB key with Unraid, I turned on the PC, and BAM! I had my NAS upgraded. This is exactly what I wanted. No mo fear about the HDDs, no more fear about the hardware. Hope it goes this way for a while. And maybe, that we'll get cheaper upgrade for the updates...

Ok, probably I read too much lot of topics (badly) and made the wrong idea it was possibile, in first place. So, in short, Parity Rebuild is mandatory if I remove a drive from the array, even an empty one. Thanks for the tip.

I stay in this topic instead of opening another one with the same title. I tried to educate myself, but I'd love a "green light" from you experts. I need to remove a drive from the array (I still have a very limited license, so have pity for my cheap configuration...), probably adding a cache SSD in the near future. Because I already did several tests with HDDs / changes / upgrades, stress the whole system with days of writes/reads, again, it's not optimal for the life of my hardware. So: 1) I installed UNBALANCED plugin, and tried to move all the data from my disk4 to other disks. I think I removed all the files in the drive I want to get rid, HOWEVER there are still two empty folders (Apps and System), and under MAIN window I see about 3GB occupied by... idunno, and this thing scares me a little 😅 EDIT: 1bis) on SHARES page, I told all my share to not use the HDD I want to remove (I excluded it). From here, this is how I think I have to proceed: 2) shut down the server 3) remove the HDD 4) restart the server, then go into TOOLS -> New Config 5) choose "Preserve current assignments" 6) probably here in New Config menu I'll see, sooner or later, an option to flag for "trust parity" 7) in MAIN, on the removed HDD slot, I simply choose "no device" If I operate this way do I preserve my system, now with a new free slot ready to be populated later, and with the Parity operative with no need to another "parity rebuild"? Thanks in advance for the attention 💜

I'm not a pro, anyway, did you try to operate with Krusader? You can install it as an APP (it creates a Docker), then in Krusader you can browse your shares, also you can navigate your network, etc. Search for useful video in youtube from SpaceInvaderOne, for example: move file with krusader

Hi everybody. Hope I don't disturb too much, with my wishlist/request. Following a video showing useful Apps, I installed Dynamix Day and Night. I tried to follow directions for the whole API stuff, saw that usually you need to pay for it, and drop it. So, I have to ask: why to have all that precise system, instead of offering (also?) a simple "passive" way, something like: start night theme: [ 21:00 ] stop night theme: [ 6:00 ] Probably this could be enough for simple (or frugal) persons like me.

Given that I'm a total noob, and I - for what is possible - avoid every solution that force me to keep opening the Terminal, or editing config files, I still want to say that I solved it with a simple WireGuard VPN installed into my router, and as an App on my android phones. When I want to use / access Nextcloud or Unraid, I simply turn the VPN on, and voilà, I'm into my local Lan with (hoping) no risks for my security. Now, I have to solve another problem with Nextcloud on my home Windows PC... but that's another matter. Edit: 😔 obviously, I don't share my file outside my network. I can't have links working for people outside my network...

Yeah, thanks for the info. Anyway, as I said, the "issues" Windows-side are minor, at least in my case. With Everything, and working directly on the network files, I'm fine. It's all the Android-side part that baffles me. I really miss those apps. However, the "dynamic" space-saving mode of file management in the cloud services in Windows 10 / 11 it's very cool (I see the same functions with Google Drive, OneDrive, Qsync etc.). I mean, it's good that if I have 12TB of shares I can see them as I actually have them all in my local drive, while I'm on a laptop with 500GB of disc space. Sure, it's not a real syncing, but it's virtually impossible to have a real sync of those big shares that (probably) we all are building with our collection of ever growing photos, videos, music, PDF manuals etc. EDIT: I would have liked to avoid this, but I'm now trying to setup the whole Nextcloud stuff, hoping for a management similar to the Qnap apps 😢

Actually, I'm trying to get accustomed to Unraid, while I still have an old Qnap that sooner or later will die for old age. Mainly, I'm missing a feature: the Qsync / Qsirch apps. On windows, it's cool and useful because I see all the folders and files as they were locals folders and files. The files that I'm seeing occupy no space on the window HDD, but there's a "cache space", so when I access to a file the first time, it's "downloaded" and quick to read/modify/etc. Every time I save the file, the app silently sync the newer version on the NAS. Also, the searches in the Qsync folders are very quick, 'cause they are treated as local files. On Windows, I can actually renounce to those features, because working directly on network files is not so painful, and I can avoid the absurdly sluggish Windows search using the free and nice Everything software. Everything reads the network folders and creates an internal list/map, so when I use it for searching a file, the results are immediate (while, sadly, Qsirch searches into the file text - for PDFs, DOCs etc., so it's doubly useful). On Android, I can't find a suitable substitute. I activated a VPN, and with a simple file browsing app I can browse the folders and download a file, but this is slow, and searches are almost prone to fail. So, if there's some cool solution that I overlooked or I totally ignore, that it's (quite) easy to setup, i'm all ears.

Ok, nice, never thought to search other pages / parts. I'm moving some stuff right now 💜

May I use this topic too? As others probably did before me, I installed the Unbalanced plugin, 'cause I'd like to try to empty a disk before to remove it from my configuration. I launch the Unbalance UI, and after the 2nd step (monitor), it gives me this text on the right window (emphases mine): So, I installed the Fix Common Problems plugin. i ran it. It gave me some suggestions about activating various alerts (mainly for security reasons). I did it. Now when I scan with it again, I get: So, I suppose here I'm done, I'm ok. But then, I'm stuck. The initial suggestion was "run the Docker Safe New Permissions command", however I can't find that command in the "Fix Common Problems" plugin. Where do I find that command? I was hoping for a UI button... I hope I didn't have to mess with the command line. Thanks in advance for your attention 💜

I retried again, this time it worked. Not sure about extra spaces, probably not, 'cause I was simply copy/pasting, however, thanks a lot for the attention. 💜

As a total noob I opened the terminal, launched the first two commands, then the quoted one. I got a github 404 error, not found.
