Denne Posted September 17, 2018 Share Posted September 17, 2018 I have/had a strange problem. I'm migrating from another Server (another OS installed) to a totally new Server with Unraid (still trial) installed. Since today I get messages from Windows that there isn't enough space left in my Media share which isn't true at all. Folder structure: Media/movies Here comes the funny part: My share is called "Media" and in there is a folder called "movies" in the "Media" share. I tried copying some files with 254GB in size to "movies" and did get the error that there isn't enough space. Tried a reboot and it didn't work. Copying less files at a time (in total more than the 254GB) seems to work fine. Tried copying the exactly same files to "Media" worked. Afterwards tried to copy the same files again to "movies" and now it works even though it didn't work before. Yesterday there weren't any problems at all copying 500GB+ at a time. I attached some screens and diagnostics (before any reboot). Anyone got an idea what is going on? Is it some config I messed up? If so why is it working after trying to copy the files to the upper directory? Any help would be much appreciated. ne0-diagnostics-20180917-1110.zip Quote Link to comment
lionelhutz Posted September 17, 2018 Share Posted September 17, 2018 Is one of the disks full? What did you set for allocation method, split level and minimum free space on the Media share? I wouldn't use a share called media. I would use a share for each type of media. IE, use a Movies share. If you have TV use a TV share. Quote Link to comment
Denne Posted September 17, 2018 Author Share Posted September 17, 2018 Hey, thanks for the reply. All the answers to your questions can be taken from the screens I attached to my first post. But here is the info you seek: Disk full? No, each disk has 5+TB free space Allocation method: Most-free Split level: Automatically split any directory as required Minimum free space: 100GB I mean it works for now, after trying to copy the files to the upper directory. I don't know if this triggered something that fixed my problem. Just wanted to know why I had it in the first place. Concerning shares: I'd like one share for media and subfolders for movies, tv shows etc.. Is there any reason this is not recommended? Quote Link to comment
JorgeB Posted September 17, 2018 Share Posted September 17, 2018 Strange problem and can't see a reason why it's happening, is any error logged when the copy fails? BTW, you might want to use a different allocation method when you add a parity disk since that one is usually slower due to overlapping parity writes. 19 minutes ago, Denne said: Concerning shares: I'd like one share for media and subfolders for movies, tv shows etc..

trurl Posted September 17, 2018 Share Posted September 17, 2018 Did you change any of the share settings after you had the problem, or were they exactly as in your screenshot? I don't see anything either. Maybe there was some problem that Windows incorrectly reported as out of space? Quote Link to comment

Do you mean in Windows or on Unraid? I did check the Unraid logs in the diagnostics folder I uploaded and didn't find anything out of the ordinary but it could well be that I missed something. 1 hour ago, johnnie.black said: BTW, you might want to use a different allocation method when you add a parity disk since that one is usually slower due to overlapping parity writes. That's really good advise, I didn't know that. Is High Water the recommended allocation method in this case? 16 minutes ago, trurl said: Did you change any of the share settings after you had the problem, or were they exactly as in your screenshot?

Than I had the problem and searched this forum and found out this isn't a good idea so I changed it to 100GB which didn't solve my problem. Everything else was and still is like in the screenshots. It could well be that this is/was a windows problem. Quote Link to comment

The syslog in Unraid. 5 minutes ago, Denne said: Is High Water the recommended allocation method in this case? Yes, High water or Fill up, depending with your preferences, both work better.

lionelhutz Posted September 18, 2018 Share Posted September 18, 2018 Should have worked unless you were trying to use the cache drive. The minimum free space should be set larger than the largest file you usually copy to avoid errors when disks are getting full. Quote Link to comment

The minimum free space should be set larger than the largest file you usually copy to avoid errors when disks are getting full. And if you did have that share using cache, then this was likely the problem. Cache has its own Minimum Free in Global Share Settings. If it has less than minimum, it will overflow to the array. Just like Minimum Free on the user shares, Unraid doesn't know how large a file will become when it begins to write it. If a disk has less than minimum, it will choose another disk. If it has more than minimum, it can choose the disk and if it runs out of space you get an error. Quote Link to comment
Denne Posted September 18, 2018 Author Share Posted September 18, 2018 The cache isn't used though for that share 😅 Quote Link to comment
