Ouze

Thanks again. Everything is good now. I reseated my cables. This reconnected the drive. I see a CRC errror count of 6. If this climbs, I will replace the cables and maybe plug into a different port. I ran the scrub and repaired corrupted blocks. I stopped docker, deleted my image, and restarted docker. Then, I reinstalled my apps from the "previously installed" spot. Very easy. I really appreciate your help.

OK - I am going to go do that now. When I do the scrub, should I check the box for "repair corrupted blocks" or not? Thank you again for holding my hand through this, I really appreciate it. I have replaced disks in the array many time no problem but this is the first time I have had to deal with issues with the cache pool so I feel especially lost.

I don't have anything important in the domains or system shares. I don't have any VMs. I'm not sure what a NOCOW share is, though? thank you

Hello all, I got a weird email so I logged into one of my Unraid boxes and found that I think sdb, one of the cache drives, might have died. I honestly have no idea what my next steps would be. I am attaching what I have for logs here. Right now the server is up and seems fine. I am hesitant to take any steps without checking in because I don't want to make it worse - I'm not sure if the disk is just unmounted, or of it's dead, or... what. Thank you! min-syslog-20230509-0436.zip min-smart-20230508-2333.zip min-diagnostics-20230508-2345.zip min-smart-20230508-2349.zip

Awesome. Thanks again!

Ok, mostly good news, some minor bad news: Before I rebooted I tried copying the syslog to disk1. It did so, but it doesn't seem to be useful: whatever broke seems to have broken prior to when the log went sideways, but attaching what I have anyway. The other minor issue: I rebooted dirty. I thought "poweroff" was safe from googling, but that clearly is not correct, as it's doing a parity check (Powerdown didn't seem to do anything). Is there a command I could be using in the future? Thank you again for the swift assistance, I really appreciate it! syslog.zip

Thank you, crossing my fingers and rebooting now. 😨

Hello all, At 0800 I got the following email from myself, as follows: When I went to check my server, every menu is blank. There is a warning about my license key missing. All shares are accessible and up. Plex via a docker is working OK. I can get in via SSH. I have re-seated the USB key, but have taken no other actions yet - I have not rebooted - for fear of making it worse. What should I do next? I'm not sure how to get diagnostics: root@Min:~# diagnostics Starting diagnostics collection... mkdir: cannot create directory ‘/boot/logs’: Input/output error done. ZIP file '/boot/logs/min-diagnostics-20211019-1130.zip' created. I don't have flash exported, so I have no way - that I know of? - to get to that path. Thank you!

Kind of a general admin question here. I have a PEC2100 with 16gb of RAM, running the current stable of Unraid. In my Docker, I have 2 main dockers: Plex and Valheim, currently. I have some other stuff that is either low impact, or just plain turned off when not actively being used. The Plex instance has maybe 4 people tops at a time, if that, Valheim has maybe 3. What kinds of things should I be looking at to determine how good I am on RAM? When I look at the dashboard, all the usage meters seem reasonable, not pegged. Should I be going any more in depth than that? Thanks!

Yeaah buddy. Thank you, that seems way less involved!

Current cache is BTRFS.

Hello all, My cache drive is no longer big enough for what I store on it. I want to replace my single 500gb SDD with a 1TB SSD. I did a search, and I found this guide: https://wiki.unraid.net/Replace_A_Cache_Drive which seems straightforward, but it's also pretty old. I believe it was last updated in 2017, before cache pools were a thing. Is that above tutorial still the best way to do it, or is it better do something with cache pool shenanigans (add the new drive to a cache pool, and then subtract the original drive) or some other new way of doing it that I hadn't found in my search? I am terrified of doing this wrong and screwing up my Plex install. Thank you!

Hi guys, I used to try to keep my directories under x number of files, because Windows would bog down when navigating them. That's not really a problem any more: since the only one looking in the directory is Plex, I almost never navigate to those directories anymore. So I was wondering: Is there a point where too many files in a directory will impact performance or cause performance problems? I have about 3,000 movies in a single directory, and it SEEMS ok, but wondering if I should start breaking those up at some point in the future. I googled it, and it seems like the answers is "no" for XFS, but those searches aren't unraid-specific. Thanks!

Ugh really sorry I didn't see this until now. I'm glad someone else showed up with that. The file he linked is what I used.

Happened again - did a check, out the output: "bunker: error: SHA256 hash key mismatch, rnal.720p.bluray.x264-reward.mkv is corrupted" According to a search, that narrows it down to 125 files. There has got to be a way to get this plugin to output more useful (specific) information, right? Why are these error messages being truncated this way? I did an md5 check against all 125 files individual checksums and of course, they pass just fine. These files got dropped onto the server once and have not been touched since then. If this plugin is going to generate output vague as it is, and as prone to false positives as it seems to be; then ultimately it's just contributing noise, not value.
