Re: [HPDD-discuss] Strange Issue, No space left, where there actually over 500TB

I believe like you said stripe count could be an issue. Our default stripe count is 1 and the applications that are running out of space are probably writing to an OST that have reached 100% on its space usage. But I assumed this being the most common case, this is something Lustre would handle it on its own? What puzzles me is why would a copy command fail at times, because during a copy I am sure file system would checked on available space on an OST and then obtained an Object index to write to where there was enough space. Do I get this right? Or Am I missing something? Should I change my default stripe count on the file system to higher than 1? Thank you for your prompt response!!
