  1. Hi, This is doing my head in! A few weeks ago I managed to unwittingly delete my entire NAS of media..... approx 35TB worth. It appears, though I still have no conclusive proof, that I may have misconfigured the Appdata backup.... Never mind, I have a tape backup, so inconvenient it certainly is, but not a disaster...... However, since then, it just gets weirder and weirder. I removed the Appdata app just in case..... I restore the media files onto the NAS.... all is fine...... and then...... they just start disappearing..... first the files.... then the folders.... It's not like.... bang, they've all gone..... they just dribble away slowly over a day or so! The way I first found out was by restoring my Plex app (on a different server) once the data was back on. Plex rebuilt all it's thumbnails and data and I thought all was hunky dory..... But then, I try and play something and Plex reported that it couldn't find the media..... Sure enough, dig into the NAS and find that the media was no longer there I've tried different ways of restoring.... e.g. putting them onto an intermediate drive before putting them on the NAS.... no different.... The NAS doesn't do anything else.... No VM's.... just a Krusader Docker and that's it. Can anybody think of any mechanism that would strip files out like this? I've virus checked it as much as I know how to, but any lines of enquiry gratefully received please. TIA tower-diagnostics-20210303-1215.zip
  2. Yep, I'd seen that and have one called "appdatabackup", so I still don't know what I did wrong.... I was meaning more into the mechanism of how it happens and why? It's one thing to read a dire warning.... it's another to understand how that happens, that's all I'm trying to do. Now that I'm fully conversant with the consequences!
  3. Wow... I still don't know what I did, but this was the very thing I was trying to sort the night before.... Ironically, because I thought I'd been a little lax in keeping on top of it.. It does seem to be something a hidden hazard for the unwary and nowhere near as overt as positively selecting stuff and hitting a big fat delete button! I've done a little reading on XFS file recovery and it seems to be an order of magnitude more difficult and less certain than other file systems... I'm sticking with restore from my tape backup for now..... The cache is full, so just the odd 30TB @40Mb/s to go....... For my understanding, and I'm sure others, is there any chance of expanding on the subject please?
  4. oh dear.... I did look at that only last last night...... If it was an "orderly deletion", rather than corruption.... Is there a possibility that file recovery utilities may still be of help?
  5. Oh dear! (that's my printable reaction.....) Can you think of any mechanism within Plex or MyMedia (or any other program) that would lead to mass deletion of files.... but not quite all them... ? Their parent folders are still there as well....
  6. Could there be any clues in my Appdata Backups? If so, what should I be looking for? The only other unusual thing that comes to mind recently is that my Docker/VM machine hosts Plex and MyMediaforAlexa and they've both been playing up. They both have paths back to the media server with the problems..
  7. No, there is/was 35TB on there! I was kinda hoping it was some kind of corrupted file system rather than complete deletion....
  8. Hi, a bit of a strange one........... I have two unraid servers, this one is mainly a NAS. After a long period of stability, I've suddenly had problems with both. With regard to this NAS, I've not done any arranging/meddling/editing recently but whole folders have gone missing. It's all media, films, photos, music etc... Most of it has gone missing, but not all of it. That to me is the strange bit.... e.g. If I'd "accidently" deleted the "FLAC" folder, it would have all gone... but it hasn't... I have remnants of it. It's exactly the same with the other folders. Any thoughts please? The other server is mainly a docker/VM machine which had completely different symptoms which I'll detail if thought necessary/relevant. I did wonder whether I'd been subject to some kind of "attack", but both do sit behind what I considered to be a tight pfsense firewall... TIA Paul tower-diagnostics-20210222-1427.zip
  9. It's nothing complicated at all.... Everything is on a standard W10 pc. The LTO drive is connected to a RocketRAID 2720 SAS Controller (Other HBA cards are available). A PCIe x8 slot required for this... With LTFS installed on windows, no other software beyond the normal file manager is required. That's a big plus because the software I used with previous LTO incarnations wasn't cheap. If you're proficient with Linux/Unix software (I'm not!), then I believe handling TAR files (Tape Archives) is native. https://en.wikipedia.org/wiki/Linear_Tape_File_System Your tape appears as a drive and you can drag and drop to your heart's content. You wouldn't want to use it like a HD, but for archiving and backup, it's perfect. Interestingly, LTO6 is a jump in capacity but not so much speed. There's a big jump for LTO7 in both capacity and speed..... but the costs are eyewatering. https://en.wikipedia.org/wiki/Linear_Tape-Open Good luck!
  10. I thought I understood DNS records! Now I'm in a tailspin..... I have.......... two domains with Godaddy, but gave control of the nameservers to Cloudflare. I have managed to corrupt the IP address in the A name in one of my domains and I can't figure out how to recover the original IP address. I thought that putting the domain name in a DNS lookup would show me the answer. Whilst the answer does belong to Cloudflare, it doesn't take me to my Godaddy webpage... My simple brain thinks that I have a web page constructed and godaddy still have that. But, if I type my domain name in the address bar, it doesn't go there.... I have a direct comparison to my other (unmolested) domain name. Also hosted by Godaddy and, again, dns handled by Cloudflare. If I type in that domain name, it correctly takes me to my Godaddy homepage. However, if I do a DNS lookup on the domain name in shows me the cloudflare NS, not the original A name IP that transferred from Godaddy in the first place. I've asked Godaddy, but yet to get a reply..... I was hoping that the assembled masses might know a way of recovering the same info. ATB Paul
  11. Sterling has picked up a bit against the dollar recently......... Typically quoted at $69.95..... Over here, they somehow translate that to £67.74....... using some unspecified, other planet, exchange rate... Thanks to ipcamtalk, they offer it at $57.99 which paypal translated to £44.74. Good deal. .........Old enough to remember when the math(s) was easy..... £1 = $2
  12. Hi, After an update of a working instance of Zoneminder, I have the problem of; Unable to connect to ZM db.SQLSTATE[HY000] [2002] No such file or directory On inspection of the log (bottom), it references the MariaDB. When I use mc to try and navigate to the floder/files referred too..... they don't exist.... presumably because the "kill" at the end deletes them? After much frustration, I installed a fresh Zoneminder on my other unRaid server. This server runs as a NAS with no other dockers........ and that works fine! So........... if it's an interaction between Zoneminder and my MariaDB, is there a workaround? I only have MariaDB because of my Nextcloud instance, and they work fine together. This server is my high core/high memory VM and docker server so, although it works, I dont want to leave Zoneminder on my NAS server. Having read through the forum, I've tried deleting templates for a fresh install from CA...... I've tried deleting log files.... but they didn't exist.... presumably because it's never done anything............ I noticed from comparing the Appdata folders that the non-working instance has an extra directory "opencv". My working version doesn't have this even though it was installed after the broken one???

  13. Well, I'm really happy to say that on my W10 machine, with a direct path of the file sitting on the NVMe drive, through the PCIe bus, direct to the tape drive gets me a constant write of 138 Mb/s. I'm a very happy bunny. What's even more pleasing is that he tape is in a constant "write" state rather than a "stop/wind/start writing again" cycle. Which must be better all round for the mechanics of both tape and drive........
  14. I'm in a working Mac.... Yay! Thanks Ed Following up with the VirtManager example, I get the following screen thrown up....... Any ideas gratefully received thanks...........
  15. Thanks for the reply, No, unfortunately not yet..... My system is in pieces at the moment. I've just acquired a rack to rehome/tidy the rats nest that my attic has become! The reboot will be an opportune time to see if that works for me. ATB
