Hi Lana, Lustre dispatches the data across several servers, MDTs and OSTs. It is likely that one of this OST is full. To see the usage per sub-component, you should check:
lfs df -h lfs df -ih See if this reports one OSTs or MDT is full.

Do not click links or open attachments unless you can confirm the sender and know the content is safe. I have a Lustre 2.12 setup running on CentOS 7. It has been working fine for some months but last night one of my users tried to untar a large file, which (among other things) created a single directory containing several million subdirectories. At that point the untar failed, reporting "no space on device". All attempts to create a file on this Lustre system now produce the same error message, but "df" and "df -i" indicate there is plenty of space and inodes left. I checked the mount point on the metadata node and it appears to have plenty of space left too. I can list directories and view files on this filesystem. I can delete files or directories on it. But even after removing a few files and a directory I cannot create a new file. If anyone can offer some help here it would be appreciated. .. Lana ([email protected]<mailto:[email protected]>)
